Optimizing Automated GUI Tests: Strategies and Best Practices

3 July 2024 Stephan Petzl Leave a comment QA

Automated GUI tests are an essential part of the software development lifecycle, ensuring that applications function correctly from an end-user perspective. However, these tests can sometimes be inefficient, leading to longer execution times. In this article, we will explore strategies to optimize automated GUI tests, making them more efficient without compromising their effectiveness.

Assess the Usefulness of Your Tests

One of the first steps in optimizing your automated GUI tests is to ensure that all tests are still relevant and useful. Over time, some tests may become obsolete or redundant. Regularly review your test suite to identify and remove any tests that no longer add value. This practice not only reduces the overall test execution time but also helps maintain the quality of your test suite.

Parallelize Test Execution

Running tests in parallel across multiple machines can significantly reduce the total execution time. By breaking down your test suite into smaller subsets and distributing them across different machines, you can achieve faster feedback. Consider using a scheduler to manage the distribution of tests and ensure consistency in test execution.

Distinguish Between Feature and End-to-End Tests

Not all tests need to simulate the entire user journey. For feature tests, focus on the specific functionality being tested and avoid unnecessary steps. Reserve end-to-end tests for scenarios that require a complete simulation of user interactions. This differentiation can help in reducing the time required for feature tests while maintaining thorough end-to-end testing.

Use Configurable Constants for Timing

Configurable constants for time intervals between actions can make your tests more adaptable. By adjusting these intervals, you can control the speed of test execution based on the current needs. For instance, you might run tests at a faster pace during regular development cycles and at a slower pace for more thorough testing over weekends.

Prioritize and Schedule Tests

Not all tests need to run every night. Prioritize your tests based on their importance and run the most critical ones first. You can schedule lower-priority tests to run less frequently, such as once a week. This approach ensures that you get the most important results quickly, saving resources and time.

Optimize Test Scripts

Efficient test scripts are crucial for reducing execution time. Avoid using static wait times; instead, use dynamic waits that check for conditions before proceeding. This ensures that your tests run as quickly as possible without unnecessary delays. Additionally, modularize your tests to allow for reusable components, making it easier to maintain and optimize them.

Invest in Hardware and Infrastructure

Sometimes, the most effective way to reduce test execution time is to invest in better hardware and infrastructure. Setting up a robust environment with multiple machines dedicated to running tests can significantly cut down on execution time. This initial investment can pay off in the long run by providing faster feedback and reducing the need for extensive test optimization.


Optimizing automated GUI tests is an ongoing process that requires regular review and adaptation. By implementing the strategies outlined above, you can make your tests more efficient and effective, ultimately improving the quality of your software.

For those looking for a no-code solution to streamline their test automation, consider using tools like Repeato. Repeato allows you to create, run, and maintain automated tests for iOS and Android applications quickly and efficiently. With its computer vision and AI capabilities, Repeato ensures that your tests are both fast and reliable, making it an excellent choice for quality assurance.
