What tools or libraries for automated testing do you prefer to use in your work?

In Go, the built-in testing package is commonly used for automated testing, allowing you to write unit tests and run them with the go test command. For more complex scenarios, libraries such as:

• Testify — extends the capabilities of the standard testing, adding convenient assertion functions.
• GoMock — for creating mocks and stubs.
• Ginkgo and Gomega — for BDD-style testing.

An example of a simple test using testing:

package mypackage

import "testing"

func TestSum(t *testing.T) {
    result := Sum(2, 3)
    if result != 5 {
        t.Errorf("Expected 5, got %d", result)
    }
}
