This blog post is part of a series about legacy coderetreat<\/a> and legacy code techniques you can apply during your work. Please click to see more sessions<\/a> about legacy code.<\/p>\n This is a codecast in Java.<\/p>\n In the previous episodes we reach the moment when we extracted one simple class. We used the The Rule of Three<\/a> and pure functions<\/a>. This newly extracted class is covered with characterization tests. But that is not enough, we want to continue adding other types of tests to understand the system better.<\/p>\n This is why during this episode you will see how to add unit tests to code extracted from a legacy code class. These tests have a small granularity level than the characterization tests we already have. This is the moment to dive more into details.<\/p>\n See this video to understand how you can document the current state of the system, by unit testing on legacy code.<\/p>\n Read here<\/a> more about this concept in my blog post.<\/p>\nCodecast<\/h3>\n
