Foster Collaboration: Encourage communication between developers, testers, and business stakeholders. This helps ensure test coverage aligns with real user needs and business goals.
By following these practices, teams can create a robust, scalable automation strategy that not only improves app quality but also accelerates release cycles. As we progress through 2025, we can expect these techniques to evolve further, driven by advancements in technology and changing market demands.
How Developers Can Enhance Testability for Automation
Making an application testable from the start is a key part of successful automation. Developers can boost testability by collaborating closely with QA teams to define test-friendly design principles early in the development process.
A few best practices include:
Assigning unique and stable identifiers to UI elements, so automated scripts can reliably locate and interact with them.
Designing modular components with predictable input and output behaviors, which simplifies writing comprehensive unit and integration tests.
Providing test hooks or configurable environments that allow testers to trigger application states or bypass complex workflows without manual effort.
Ensuring that logs and error messages are detailed and actionable, aiding rapid diagnosis of failures detected during automated testing.
By considering these aspects throughout development, teams can streamline the automation process, reduce script maintenance headaches, and improve the overall reliability of automated tests.
Limitations of Emulators and Simulators
While emulators and simulators offer a convenient way to test mobile apps during early development stages, they have notable limitations when it comes to replicating real-world user experiences. These tools can only partially reproduce the behavior and conditions of physical devices.
Limited Realism: Emulators and simulators often fall short in mimicking hardware-specific conditions, such as battery drain, varying processor speeds, or fluctuating network connectivity (like switching between 2G, 4G, and 5G). For example, it's challenging to simulate a weak Wi-Fi signal or low battery situation accurately.
Incomplete Sensor Support: Features relying on device sensors (GPS, accelerometer, gyroscope, etc.) may not be fully supported. Real-world interactions, such as shaking the device or changing orientation in unpredictable ways, are difficult to reproduce reliably.
Fragmentation Challenges: The diversity of actual devices—considering differences in screen size, manufacturer modifications, and operating system versions—is difficult to capture in simulated environments. Testing exclusively on emulators might miss device-specific bugs or compatibility issues.
Performance vs. Reality: An app that performs smoothly on an emulator or simulator may still experience lag, rendering issues, or unexpected crashes on a real device with limited resources.
User Experience Gaps: Automated tools cannot truly replicate unique quirks users experience in daily life, like incoming calls or background app interference, which may affect app behavior in complex ways.
Due to these limitations, relying solely on emulators and simulators can lead to gaps in test coverage and may allow significant issues to slip through to users in production. A comprehensive mobile testing strategy should combine both simulated environments and real device testing to ensure apps deliver consistent and reliable experiences in the hands of actual users.
Leveraging Accessibility IDs for Enhanced Testability
Effectively incorporating accessibility IDs into your mobile application can make a significant difference in your automation testing process. Assigning unique accessibility IDs to UI elements enables test automation tools—such as Appium and others—to easily and reliably identify these elements, regardless of changes in layout or screen hierarchy.
This approach offers several benefits:
Improved Stability: Unlike XPath selectors, which can be fragile and susceptible to breaking with UI updates, accessibility IDs provide a stable locator strategy. This reduces test maintenance and flakiness.
Expanded Test Coverage: With well-defined accessibility IDs, testers can script more complex and flexible user interactions, allowing for broader scenario coverage across both Android and iOS devices.
Inclusive Development: Utilizing accessibility IDs not only enhances testability but also contributes to better app accessibility for users with assistive technologies.
By making UI elements more accessible to automation scripts, development teams can streamline their testing efforts, increase reliability, and ensure their apps are robust across a wide range of devices and use cases.
Considering View States in Mobile App Testing
One crucial aspect often overlooked in mobile app automation testing is the management of view states within the application. View states refer to the specific condition or configuration a page or screen is in at any given point—capturing details like entered data, user choices, and navigational progress. Paying attention to view states can make a significant difference in the efficiency and effectiveness of your testing process.
When automating tests, starting each scenario from the appropriate view state helps avoid unnecessary repetition. For example, if multiple test cases require you to log in and navigate to a specific page, resetting the view state for each test can save testers from repeating the same setup steps. Not only does this streamline test execution, but it also ensures that testing time is spent validating unique functionalities rather than routine navigation.
Carefully managing view states allows teams to:
Reduce duplicated setup steps, increasing overall test execution speed
Focus resources on verifying new or complex app behaviors, rather than routine actions
Minimize the risk of introducing errors during repetitive navigation
Ensure tests are more maintainable and adaptive to changes in application flow
By incorporating smart handling of view states into your automation strategy, you can dramatically cut down on wasted effort and improve both the accuracy and coverage of your testing activities.
Best Practices for Arranging Selectors in Test Automation
Selecting the right element locator is a vital part of building efficient and stable automated tests. The order in which you arrange selectors can have a significant impact on both performance and reliability.
As a general rule, prioritize selectors in the following order:
ID: IDs are unique and, when available, provide the fastest and most reliable way to identify elements.
Name or Accessibility Attributes: For elements without IDs, consider attributes like
name
,aria-label
, oraccessibilityId
as these are usually stable and descriptive.CSS Selectors: CSS selectors offer flexibility and are generally faster than other location strategies, making them a solid fallback option.
Link Text: When working with links, using link text can be effective if the text is unique and unlikely to change.
XPath: Reserve XPath for situations where no other selector works. While powerful, XPath expressions can be more brittle to UI changes and tend to be slower, especially on complex mobile interfaces.
By consistently following this hierarchy—starting from the most specific and performant selectors and moving to the more general—you can reduce test flakiness and improve execution speed. Aim to review your selectors periodically to maintain efficient and robust test scripts.
Use XPath with Care in Mobile App Automation
While XPath is a powerful tool for locating elements within an app’s user interface—especially when navigating complex hierarchies—it’s important not to rely on it excessively during mobile automation testing. Unlike native selectors provided by Apple and Google, XPath queries often require additional behind-the-scenes processing. When a testing tool like Appium needs to interpret XPath, it undertakes extra steps to traverse the app’s structure, which can slow down test execution.
Overusing XPath can negatively impact the overall performance of your tests, leading to longer run times and less efficient automation. It may also become brittle with frequent updates to UI layouts, causing maintenance headaches down the line. Instead, consider using more efficient selector strategies, like accessibility IDs or class names, which are typically faster and more reliable for mobile environments.
Understanding these aspects of mobile app automation testing is crucial for effectively implementing and managing an automation strategy. By leveraging the benefits while being aware of the challenges, teams can significantly enhance their mobile app testing processes, leading to higher quality applications and faster release cycles.
Best Practices for Automated Mobile App Testing
To get the most out of automation, keep these essential best practices in mind:
Build Testable Apps from the Start: Open communication between developers and testers is critical. Developers should assign unique IDs to UI elements to make automated identification and interaction easier.
Be Mindful with XPath Usage: While XPath is a powerful tool for navigating elements, it can be slower and less efficient—especially since it isn’t natively supported by iOS or Android automation frameworks. Relying too heavily on XPath can lead to performance bottlenecks. Whenever possible, prioritize faster locator strategies, such as IDs or accessibility IDs.
Order Selectors Logically: Arrange your element selectors so that the most efficient (like ID) are used first, falling back to slower methods like XPath only as a last resort. This helps speed up test execution and reduces flakiness.
Use Accessibility IDs: Assigning accessibility IDs to elements not only improves app accessibility for users but also makes automated tests more reliable and maintainable.
Optimize for View States: Avoid redundant test steps by designing your tests to start in the correct app state. For example, if multiple tests require the user to be logged in, set up the necessary state programmatically, rather than repeating login steps in every test.
Mix Real Devices and Emulators/Simulators: Emulators and simulators are useful for early development, but they can’t always replicate real-world conditions such as varying network speeds, battery states, or hardware differences. For comprehensive coverage, include testing on a diverse set of real devices to uncover issues that might slip through on virtual ones.
Applying these best practices not only streamlines the automation process, but also ensures higher quality releases and better alignment between development and testing teams.
As we progress through 2025, we can expect these techniques to evolve further, driven by advancements in technology and changing market demands.

Optimize for View States: Avoid redundant test steps by designing your tests to start in the correct app state. For example, if multiple tests require the user to be logged in, set up the necessary state programmatically, rather than repeating login steps in every test.
Mix Real Devices and Emulators/Simulators: Emulators and simulators are useful for early development, but they can’t always replicate real-world conditions such as varying network speeds, battery states, or hardware differences. For comprehensive coverage, include testing on a diverse set of real devices to uncover issues that might slip through on virtual ones.
Applying these best practices not only streamlines the automation process, but also ensures higher quality releases and better alignment between development and testing teams.
As we progress through 2025, we can expect these techniques to evolve further, driven by advancements in technology and changing market demands.
As mobile app development continues to evolve, so do the techniques for automation testing. In 2025, several approaches stand out for their effectiveness in ensuring app quality, speed, and reliability. Let's explore these techniques in detail.
A. Continuous Integration/Continuous Deployment (CI/CD) Integration
Integrating automation testing into CI/CD pipelines has become a cornerstone of modern mobile app development. This approach ensures that every code change is automatically tested before it's merged into the main codebase. In a CI/CD workflow, each code commit triggers an automated build process, followed by a series of automated tests including unit tests, integration tests, and UI tests. This provides developers with immediate feedback on the impact of their changes.
The benefits of CI/CD integration are numerous. It allows for faster detection and resolution of bugs, improves overall code quality, and significantly reduces time-to-market. Moreover, it increases confidence in releases by ensuring that every change has passed through a comprehensive testing process.
Implementing CI/CD requires careful planning and the right set of tools. Popular options for mobile app development include Jenkins, CircleCI, and GitLab CI. These can be integrated with mobile-specific tools like Fastlane to automate the build and deployment processes, creating a seamless pipeline from code commit to app store submission.
B. Cloud-Based Testing
Cloud-based testing has gained significant traction, offering scalability and access to a wide range of devices without the need for physical hardware. This approach allows teams to test on hundreds of real devices and OS versions, run tests simultaneously on multiple devices, and easily scale their testing infrastructure based on project needs.
One of the key advantages of cloud-based testing is its cost-effectiveness. By reducing the need for in-house device labs, companies can significantly cut down on hardware and maintenance costs. Moreover, cloud platforms provide easy access to the latest devices and OS versions, ensuring that apps can be tested on the most current configurations.
While emulators and simulators remain helpful for initial development and quick checks, they are limited in their ability to mimic real-world user conditions. For example, emulators cannot accurately reproduce scenarios like low battery, varying network speeds (such as switching to a 2G connection), or the behavior of device-specific sensors. Relying solely on virtual devices can lead to undetected bugs or negative user experiences when the app is deployed to actual users.
Testing on real devices through the cloud addresses these shortcomings. Teams can interact with native device features, test geolocation scenarios, and throttle network conditions to simulate a wide range of real-world environments. Many cloud platforms also integrate seamlessly with popular mobile testing frameworks such as Appium, EarlGrey, and XCUITest, making it easier to automate and manage complex test suites.
This comprehensive access to diverse devices and testing conditions results in more robust, reliable apps—and ultimately, happier users.
Popular cloud-based testing platforms include AWS Device Farm, Firebase Test Lab, and Sauce Labs. These platforms often provide additional features like video recordings of test runs, detailed logs, and performance metrics, which can be invaluable for debugging and optimizing app performance.
When implementing cloud-based testing, it's important to consider factors like data security, network latency, and integration with existing CI/CD pipelines. Despite these considerations, the benefits of increased test coverage and faster execution through parallelization make cloud-based testing an attractive option for many development teams.
C. AI and ML in Mobile App Testing
Artificial Intelligence (AI) and Machine Learning (ML) are revolutionizing mobile app testing by making it more intelligent and efficient. These technologies are being applied in various aspects of testing, from test case generation to bug prediction.
With the increase in smartphone penetration and the sheer amount of time users spend on their devices, delivering a seamless mobile app experience is now mission-critical. To achieve this, teams must not only select the right testing frameworks but also embrace best practices that leverage the latest advancements, including AI and ML.
AI can analyze an app and generate relevant test cases, potentially uncovering edge cases that human testers might miss. ML algorithms can adapt tests to UI changes, reducing the maintenance burden of test scripts. In visual testing, AI can detect subtle anomalies and inconsistencies across different devices, ensuring a consistent user experience.
Tools like Testim, Applitools, and Test.ai are at the forefront of incorporating AI/ML into mobile app testing. These platforms offer features like AI-driven functional testing, self-healing tests, and predictive analytics for identifying high-risk areas of an app.
While the potential of AI/ML in testing is enormous, it's important to maintain a balance with human oversight. The technology is best used to augment human testers, not replace them entirely. As these technologies continue to evolve, we can expect even more sophisticated applications in mobile app testing.
By strategically adopting AI- and ML-powered solutions as part of a comprehensive testing strategy, development teams can accelerate release cycles, improve app quality, and deliver the kind of seamless experience that today’s mobile users expect.
D. Test-Driven Development (TDD) Approach
Test-Driven Development is a software development approach where tests are written before the actual code. In mobile app development, TDD can significantly improve code quality and reduce bugs. The TDD cycle involves writing a failing test, writing the minimum amount of code to pass the test, and then refactoring the code.
For iOS development, the XCTest framework is commonly used for TDD. Android developers often rely on JUnit and Espresso. For cross-platform development, Appium can be used in conjunction with various unit testing frameworks.
The benefits of TDD include cleaner, more modular code, improved code coverage, and easier refactoring. It also leads to a better understanding of requirements, as developers need to think through the expected behavior of the code before writing it.
Implementing TDD requires a shift in development mindset and may initially slow down development. However, it often leads to fewer bugs and easier maintenance in the long run, making it a valuable approach for many mobile development teams.
E. Behavior-Driven Development (BDD) Frameworks
BDD extends the concept of TDD by focusing on the behavior of the application from the end user's perspective. It bridges the gap between technical and non-technical team members by using natural language to describe app behavior. In BDD, scenarios are typically written in a Given-When-Then format, making them accessible to all stakeholders.
Popular BDD frameworks for mobile testing include Cucumber, which works well with Appium for cross-platform testing; Specflow, which integrates with .NET for Windows app testing; and Jasmine, often used with Protractor for hybrid app testing.
The primary advantage of BDD is improved communication between team members. It provides clear documentation of app behavior and creates tests that closely align with user stories and acceptance criteria. This approach can lead to more user-focused development and testing processes.
Implementing BDD requires training for the entire team and a commitment to collaborative test creation. However, the resulting improvements in communication and alignment between development, testing, and business objectives can make it a worthwhile investment for many mobile app development teams.
By leveraging these techniques, mobile app development teams can significantly enhance their automation testing processes. The key is to choose the approaches that best fit the project requirements, team skills, and overall development strategy. As we progress through 2025, we can expect these techniques to evolve further, driven by advancements in technology and changing market demands.
To maximize the benefits of automated mobile app testing, consider the following best practices:
Start Early and Integrate Often: Begin automation as early as possible in the development lifecycle and integrate tests into your CI/CD pipelines. This ensures rapid feedback and helps catch issues when they’re easiest to fix.
Prioritize Test Cases: Not every test should be automated. Focus on repetitive, high-value, and regression-prone scenarios first. Functional, performance, and compatibility tests are often ideal candidates.
Maintain Clear Test Data Management: Use consistent and reliable test data to ensure stable, repeatable results. Isolate test environments to minimize flakiness and reduce false positives or negatives.
Keep Tests Modular and Maintainable: Write modular test scripts so they’re easy to update as your app evolves. Regularly review and refactor tests to keep the suite lean and effective.
Leverage Real Devices and Emulators: Balance your use of real devices with emulators and simulators to cover a broad range of device types, OS versions, and network conditions.
Monitor and Analyze Results: Don’t just run tests—review the outcomes. Analyze failed tests to identify root causes, address flaky tests promptly, and use reporting tools for actionable insights.
Foster Collaboration: Encourage communication between developers, testers, and business stakeholders. This helps ensure test coverage aligns with real user needs and business goals.
By following these practices, teams can create a robust, scalable automation strategy that not only improves app quality but also accelerates release cycles. As we progress through 2025, we can expect these techniques to evolve further, driven by advancements in technology and changing market demands.
How Developers Can Enhance Testability for Automation
Making an application testable from the start is a key part of successful automation. Developers can boost testability by collaborating closely with QA teams to define test-friendly design principles early in the development process.
A few best practices include:
Assigning unique and stable identifiers to UI elements, so automated scripts can reliably locate and interact with them.
Designing modular components with predictable input and output behaviors, which simplifies writing comprehensive unit and integration tests.
Providing test hooks or configurable environments that allow testers to trigger application states or bypass complex workflows without manual effort.
Ensuring that logs and error messages are detailed and actionable, aiding rapid diagnosis of failures detected during automated testing.
By considering these aspects throughout development, teams can streamline the automation process, reduce script maintenance headaches, and improve the overall reliability of automated tests.
Limitations of Emulators and Simulators
While emulators and simulators offer a convenient way to test mobile apps during early development stages, they have notable limitations when it comes to replicating real-world user experiences. These tools can only partially reproduce the behavior and conditions of physical devices.
Limited Realism: Emulators and simulators often fall short in mimicking hardware-specific conditions, such as battery drain, varying processor speeds, or fluctuating network connectivity (like switching between 2G, 4G, and 5G). For example, it's challenging to simulate a weak Wi-Fi signal or low battery situation accurately.
Incomplete Sensor Support: Features relying on device sensors (GPS, accelerometer, gyroscope, etc.) may not be fully supported. Real-world interactions, such as shaking the device or changing orientation in unpredictable ways, are difficult to reproduce reliably.
Fragmentation Challenges: The diversity of actual devices—considering differences in screen size, manufacturer modifications, and operating system versions—is difficult to capture in simulated environments. Testing exclusively on emulators might miss device-specific bugs or compatibility issues.
Performance vs. Reality: An app that performs smoothly on an emulator or simulator may still experience lag, rendering issues, or unexpected crashes on a real device with limited resources.
User Experience Gaps: Automated tools cannot truly replicate unique quirks users experience in daily life, like incoming calls or background app interference, which may affect app behavior in complex ways.
Due to these limitations, relying solely on emulators and simulators can lead to gaps in test coverage and may allow significant issues to slip through to users in production. A comprehensive mobile testing strategy should combine both simulated environments and real device testing to ensure apps deliver consistent and reliable experiences in the hands of actual users.
Leveraging Accessibility IDs for Enhanced Testability
Effectively incorporating accessibility IDs into your mobile application can make a significant difference in your automation testing process. Assigning unique accessibility IDs to UI elements enables test automation tools—such as Appium and others—to easily and reliably identify these elements, regardless of changes in layout or screen hierarchy.
This approach offers several benefits:
Improved Stability: Unlike XPath selectors, which can be fragile and susceptible to breaking with UI updates, accessibility IDs provide a stable locator strategy. This reduces test maintenance and flakiness.
Expanded Test Coverage: With well-defined accessibility IDs, testers can script more complex and flexible user interactions, allowing for broader scenario coverage across both Android and iOS devices.
Inclusive Development: Utilizing accessibility IDs not only enhances testability but also contributes to better app accessibility for users with assistive technologies.
By making UI elements more accessible to automation scripts, development teams can streamline their testing efforts, increase reliability, and ensure their apps are robust across a wide range of devices and use cases.
Considering View States in Mobile App Testing
One crucial aspect often overlooked in mobile app automation testing is the management of view states within the application. View states refer to the specific condition or configuration a page or screen is in at any given point—capturing details like entered data, user choices, and navigational progress. Paying attention to view states can make a significant difference in the efficiency and effectiveness of your testing process.
When automating tests, starting each scenario from the appropriate view state helps avoid unnecessary repetition. For example, if multiple test cases require you to log in and navigate to a specific page, resetting the view state for each test can save testers from repeating the same setup steps. Not only does this streamline test execution, but it also ensures that testing time is spent validating unique functionalities rather than routine navigation.
Carefully managing view states allows teams to:
Reduce duplicated setup steps, increasing overall test execution speed
Focus resources on verifying new or complex app behaviors, rather than routine actions
Minimize the risk of introducing errors during repetitive navigation
Ensure tests are more maintainable and adaptive to changes in application flow
By incorporating smart handling of view states into your automation strategy, you can dramatically cut down on wasted effort and improve both the accuracy and coverage of your testing activities.
Best Practices for Arranging Selectors in Test Automation
Selecting the right element locator is a vital part of building efficient and stable automated tests. The order in which you arrange selectors can have a significant impact on both performance and reliability.
As a general rule, prioritize selectors in the following order:
ID: IDs are unique and, when available, provide the fastest and most reliable way to identify elements.
Name or Accessibility Attributes: For elements without IDs, consider attributes like
name
,aria-label
, oraccessibilityId
as these are usually stable and descriptive.CSS Selectors: CSS selectors offer flexibility and are generally faster than other location strategies, making them a solid fallback option.
Link Text: When working with links, using link text can be effective if the text is unique and unlikely to change.
XPath: Reserve XPath for situations where no other selector works. While powerful, XPath expressions can be more brittle to UI changes and tend to be slower, especially on complex mobile interfaces.
By consistently following this hierarchy—starting from the most specific and performant selectors and moving to the more general—you can reduce test flakiness and improve execution speed. Aim to review your selectors periodically to maintain efficient and robust test scripts.
Use XPath with Care in Mobile App Automation
While XPath is a powerful tool for locating elements within an app’s user interface—especially when navigating complex hierarchies—it’s important not to rely on it excessively during mobile automation testing. Unlike native selectors provided by Apple and Google, XPath queries often require additional behind-the-scenes processing. When a testing tool like Appium needs to interpret XPath, it undertakes extra steps to traverse the app’s structure, which can slow down test execution.
Overusing XPath can negatively impact the overall performance of your tests, leading to longer run times and less efficient automation. It may also become brittle with frequent updates to UI layouts, causing maintenance headaches down the line. Instead, consider using more efficient selector strategies, like accessibility IDs or class names, which are typically faster and more reliable for mobile environments.
Understanding these aspects of mobile app automation testing is crucial for effectively implementing and managing an automation strategy. By leveraging the benefits while being aware of the challenges, teams can significantly enhance their mobile app testing processes, leading to higher quality applications and faster release cycles.
Best Practices for Automated Mobile App Testing
To get the most out of automation, keep these essential best practices in mind:
Build Testable Apps from the Start: Open communication between developers and testers is critical. Developers should assign unique IDs to UI elements to make automated identification and interaction easier.
Be Mindful with XPath Usage: While XPath is a powerful tool for navigating elements, it can be slower and less efficient—especially since it isn’t natively supported by iOS or Android automation frameworks. Relying too heavily on XPath can lead to performance bottlenecks. Whenever possible, prioritize faster locator strategies, such as IDs or accessibility IDs.
Order Selectors Logically: Arrange your element selectors so that the most efficient (like ID) are used first, falling back to slower methods like XPath only as a last resort. This helps speed up test execution and reduces flakiness.
Use Accessibility IDs: Assigning accessibility IDs to elements not only improves app accessibility for users but also makes automated tests more reliable and maintainable.
Optimize for View States: Avoid redundant test steps by designing your tests to start in the correct app state. For example, if multiple tests require the user to be logged in, set up the necessary state programmatically, rather than repeating login steps in every test.
