More Description:
The video is about how to refactor legacy code without affecting existing functionality. The speaker discusses an example of code, which lacks unit tests and has a method that needs to be refactored. The speaker emphasizes the importance of having a fully covered code before refactoring. They introduce the concept of snapshot testing, where they use the library called Verify to create a snapshot of the test result. The speaker demonstrates how to use Verify to generate data for all conditions of the method, using nested loops to create all possible combinations of values that the method accepts. The goal is to generate unit test coverage of 100% for the code.
