Why Should You Prefer Flaky Tests For Testing Software?

Testing of software programs before using them ensures that the software behaves as expected under various conditions. There are numerous methods to test the software, and one of them is called flaky test. These tests play an important role in discovering hidden bugs and ensure the robustness of the software systems. There are many reasons for why you should refer to this test over any other testing method, and some points are mentioned below.

Reveals non-deterministic behaviour: This test is designed to uncover the non-deterministic behaviour of the software applications. It is a situation where the results of any operations are not predictable. This test help to identify such problems and the test may pass or fail as per the race condition or the timing issues. By detecting such issues in the software, you can improve the program.
Hidden defects: Software systems are complex and comprise of numerous components interacting in many ways. In such cases flaky tests can help to detect the defects in the software program. If you are able to detect these problems at an early stage, then the test can prevent big issues that may happen in the future, saving both time and resources.
Reliability: During the development of any software, these tests act as the backbone of the software applications. To maintain the integrity of the software, you should pass it through these tests so that problems can be identified and fixed before they become big. That’s why developers ensure that the test remains reliable and provides accurate feedbacks on the behaviour of software.
Continuous improvements: For a continuous improvement during the development period, flaky test are preferred. If the test fails, then developers delve deeper into its cause, and does a good introspection of the problem and tries to solve. By addressing the root cause of the problem, developers are able to strengthen their software programs leading to higher quality applications.
Real-world conditions: In the real world, software operates in a dynamic environment where external factors can also influence its behaviour. But, flaky tests help to simulate these unpredictable conditions that the software may encounter during the production. Software that withstands the test is considered better and is able to handle bugs and changes in the real world.

Conclusion:

While you are using the flaky tests at the beginning of your programs, you may think they can create problems, but these tests are invaluable and can help you develop a good software application. Flaky tests reveal the non-deterministic behaviour, hidden defects, and enhance the reliability and continuous improvement in the software. By performing this test, you can also reflect real-world conditions and find ways to improve those.

During testing process if flakiness appears at an early stage, then developers can build much stronger and dependable software that can stand the test of time. This will not only save your time but will also use less resource and make your software bug free.
