In this chapter, we have learned about the unittest, which is Python's unit testing framework. We also learned about how to create test cases and methods used in unit testing.

In the next chapter, we are going to learn how to automate the regular administrative activities of the system administrator. You will learn about accepting inputs, handling passwords, executing external commands, reading config files, adding warning codes to scripts, setting CPU limits, web-browser launching, using the os module, and taking backups.
