“ Similarly, we don’t write unit tests for every new feature. The thing that hinders our ability to unit test is precisely the focus on static structures. Static methods and properties are global, harder to replace at runtime, and therefore, harder to “stub” or “mock.” Those capabilities are very important for proper isolated unit testing.” Is it in C#? That’s surprising. It’s relatively easy to stub and mock things out in C++, so you don’t need all these “testability” patterns, although I do find passing dependencies around as constructor parameters or properties makes code easier to understand overall.
