TLDR: Read Michael Feathers "Working Efficiently with Legacy Code". This course falls short - a promise of teaching how to deal with legacy code in 1 hour ends up causing more harm than good.
The course oversimplifies, offering basic suggestions that you probably already know. The recommendation to rapidly achieving code coverage using the approval testing library assumes the code adheres to specific patterns and that you possess knowledge of various inputs and expected results. This may not be the case for complex systems. Additionally, the refactoring suggestion lacks emphasis on the crucial need for a test harness before making any changes.
