CDP 207 design patterns in automated testing
Test code is code. This cannot be emphasized enough. So many developers don't treat tests as real code that needs to be designed with longevity in mind. Just like in other areas of the code patterns have emerged to aid in the design of tests.
To have successful automation in testing you need to design your test code correctly. Testing design patterns are solutions or ways of setting up code that have been successful over and over again. They were created to solve common problems are generally considered to be best practices in writing the code that tests other code.
This is a high level overview of some of the design patterns used in automated testing. Since test code is code these are similar to coding design patterns. The implementation details will vary between languages and frameworks. Use this information to understand the concepts behind these patterns when you are learning or implementing them in your own testing.
