Summary
In this chapter, you learned how to use the unit test library to begin a new project using TDD. Even though we only have two tests, we already have a working logging library that is easy to use and understandable by any C++ developer.
The two tests will help ensure we don’t break the simple design started in this chapter as we extend the logging library in later chapters. The next chapter, in particular, will extend the logging library to better fit the needs of our intended user, a micro-services developer. We’ll be adding the ability to tag log messages and then use the tags to enable powerful filtering options.
