Summary

This chapter was about a recent addition to Go testing, which is fuzz testing. Fuzz testing can help you find bugs in your code by generating test data on its own. While fuzz testing offers several benefits, it is important to note that it is not a silver bullet. This means that it should be used in conjunction with other testing techniques and security practices to ensure comprehensive coverage and robust security measures.

You might say that after making sure that your software has no bugs, you may need to make it faster. In such cases, you need to understand how your resources are being used—observability is about collecting performance-related information that helps you identify the behavior of your application.

Observability is crucial in modern, complex systems where traditional monitoring methods may fall short. It enables engineers and operators to gain insights into the inner workings of a system, diagnose problems, and improve the overall system reliability...
