How Can I Efficiently Skip Specific Go Tests?

Skipping Tests with Go Test: Custom Exclusion and Efficiency

When running integration tests in Go with the go test command, it can be cumbersome to manually specify all tests to exclude. This article explores methods for excluding specific tests efficiently.

Individual Test Exclusion

The testing package offers SkipNow() and Skip() methods to skip individual tests:

func skipCI(t *testing.T) {
  if os.Getenv("CI") != "" {
    t.Skip("Skipping testing in CI environment")
  }
}

func TestNewFeature(t *testing.T) {
  skipCI(t)
}

By prepending skipCI() to a test, you can skip it under specific conditions (such as when running in a CI environment).

Short Mode Exclusion

Another option is to use the short mode of go test. Add a guard to a test:

if testing.Short() {
  t.Skip("skipping testing in short mode")
}

When you run tests with go test -short, tests containing this guard will be skipped.

Advantages of Custom Exclusion

Custom exclusion methods provide several advantages:

• Precision: Exclude specific tests without having to specify all the tests to run.
• Flexibility: Skip tests based on conditions, such as the environment or server availability.
• Efficiency: Avoids performing unnecessary tests, especially for large test suites.
