Question 1

How to use Testza for fuzz testing in Go?

Accepted Answer

Testza provides functions like FuzzStringEmailAddresses to generate input sets and FuzzUtilRunTests to execute tests on each input. For example, you can create a test set of email addresses and run validation logic on each one, as shown in the README's fuzzing example.

Question 2

Testza vs Testify: which is better for Go testing?

Accepted Answer

Testza offers more built-in features like fuzzing and snapshots, while Testify is more established with a focus on assertions and mocking. Choose Testza if you need advanced utilities, or Testify for a simpler assertion library with broader community adoption.

Question 3

Can I disable the colorful output in Testza?

Accepted Answer

Yes, you can disable colored output by calling SetColorsEnabled(false) in the init() function or using the command-line flag --testza.disable-color. This is useful for CI systems that don't support ANSI colors, as noted in the settings documentation.

Question 4

How do I capture stdout in tests with Testza?

Accepted Answer

Use the CaptureStdout function by passing a function that writes to stdout, such as fmt.Println. It returns the captured string, which you can assert against expected output, as demonstrated in the README's CLI testing example.

Question 5

What are snapshots in Testza and when should I use them?

Accepted Answer

Snapshots allow you to save an object's state and validate it in future test runs to ensure consistency. Use them for regression testing in scenarios like API responses or data structures, with functions like SnapshotCreateOrValidate handling the process.

Question 6

Is Testza compatible with Go modules?

Accepted Answer

Yes, Testza is a Go module and can be installed using 'go get github.com/MarvinJWendt/testza'. It integrates seamlessly with the standard go test tool, so it works with Go modules without additional setup.
