Part 3: Advanced Testing Techniques

The final part is dedicated to discussing the more challenging aspects of testing complex Go code, as all the tools and techniques required for testing applications are provided by the previous two sections. We begin our exploration by learning about Go concurrency mechanisms and what the concurrency untestable conditions are, including how to use Go’s race detector. Then, we revisit and expand our testing of edge cases by making use of fuzz tests and property-based testing, allowing us to test our code with a large amount of input to ensure that it is robust. Finally, we explore how to leverage Go’s recently introduced generics capability to write code that can work with different types, learn how to change table-driven tests to verify generic code, and leverage generics to create custom test utilities.

This part has the following chapters:

• Chapter 9, Challenges of Testing Concurrent Code
• Chapter 10, Testing Edge Cases...
