Testing Go code

The subject of this section is the testing of Go code by writing test functions. Software testing is a very large subject and cannot be covered in a single section of a chapter in a book. So, this section tries to present as much practical information as possible.

Go allows you to write tests for your Go code to detect bugs. However, software testing can only show the presence of one or more bugs, not the absence of bugs. This means that you can never be 100% sure that your code has no bugs!

Strictly speaking, this section is about automated testing, which involves writing extra code to verify whether the real code—that is, the production code—works as expected or not. Thus, the result of a test function is either PASS or FAIL. You will see how this works shortly. Although the Go approach to testing might look simple at first, especially if you compare it with the testing practices of other programming languages, it is very efficient and effective...
