On occasion, when executing a test suite for multiple classes, the act of mocking is omitted.

edit

This can lead to inaccurate results and can undermine the overall integrity of the test suite. Since mocking is an important part of testing, it should always be included in any test suite that involves multiple classes. A failure to do so can result in unexpected behavior and can cause developers to waste time debugging code that should have been caught by the test suite. As a general rule, always include mocking as part of your testing process, and make sure to thoroughly test all classes in your system. This will help ensure that your code is reliable and that your tests are accurate and effective.
