BDD can be applied for any type of testing including unit tests, component, integration as well as for many other types. Consider Using a BDD FrameworkīDD is a software development methodology in which software is implemented in the way its behavior is described. Of course you should always run all of these test types! But you always need to think twice if you have some high-level tests that can be completely replaced by low-level, and having them in the UI suite is just redundant. That’s why we have chose to include it at the top of our best practices chart.ĭon’t understand me incorrectly. This whole Agile test automation pyramid mentioned in the beginning of the paragraph was applied with great success in many famous companies across the world. That’s why, in the automation process, I take the dark side first. It nicely represents the stability of low-level tests (black) and high-level tests (white). When somebody asks me why I prefer more low-level tests in my test automation frameworks, I like to show them this picture. Third, low-level tests are much more stable than high-level ones. Of course, this also saves you a lot of costs. If this is true for your project, then you can even say that you do not only catch but you prevent bugs and do not let them get into the project repository. Usually, unit tests are run before each commit in your repository. Second, low-level tests are executed much earlier in the test automation pipeline. Faster feedback from tests execution allows you to catch issues early on, saving you huge amounts of costs. Why is this important? Mainly, because faster tests give you faster feedback. Unit tests are faster than API tests while API tests are much faster than UI tests. First, low-level tests are much faster by nature. Let’s try to think why the pyramid was constructed this way. It shows the recommended proportion of tests to be implemented on each test level, if you want to have a solid test automation pipeline. This is a representation of the agile test pyramid initially designed by Mike Cohn, one of the most successful and wise Agile and Scrum instructors. You always need to remember that high-level tests should be only the third defense shield, for catching all the remaining issues that were not caught on the first two levels. Ideally, you should be confident that if you remove your whole UI automation suite from the test cycle, you will be able to catch up to 90% of existing bugs in your release. One of the main best practices you should consider at first - do not rely on UI test automation alone. Use data-driven instead of repeated testsġ.Make tests simpler instead of adding comments.Take screenshots for failure investigation.Make your test automation framework portable.Separate your tests from your test automation framework.Do not run ALL tests across ALL target browsers.NEVER use Thread.sleep() unless there are specific test requirements.Always use test design patterns and principles.You can reference an example test project on GitHub. Please, feel free to use, fork, improve and share your thoughts!īefore we dive into each principle, here is a summary of the best practices that I am going to talk about, for your convenience: UI Test Automation Best Practices All the principles are still the same and you can easily apply the same rules on your situation as soon as you understand the main concept. But don’t worry if Java language or Serenity are not the tools you plan on using for your framework creation. In addition, I have used Serenity test automation framework as a base framework for my solution, which worked great for me in a couple of past projects. The example UI test automation framework and all the code snippets are based on the Java programming language. You can use it as a starting point for your framework as well. ![]() In addition, I have prepared a fully working UI automation framework that was created following these mentioned principles below. We will also go over some handy examples for each of these principles. In this article, I will aggregate and define the 15 top best practices for creating a solid and maintainable UI testing automation framework.
