Testing, checking, linting

Abstract

Chapter 2 covers tools that help you identify mistakes in your code, such as automated testing and linting tools. These tools all make it easier to write code that you can be confident in, whether it's a large codebase, one that you rarely need to edit, or one that will garner contributions from third parties. The tools covered here are all ones I would recommend; however, the focus will be on understanding their advantages and disadvantages. You may have used one or more of these tools, and you may have opinions on whether some of them are appropriate to use. This chapter will help you understand the trade-offs to help you make informed decisions.
