How Can I Effectively Separate Unit and Integration Tests in Go?

Best Practices for Separating Unit and Integration Tests in Go

Introduction:

To separate unit and integration tests effectively in Go using testify, it's essential to follow established best practices. This allows you to control which tests to include based on project requirements.

Solution:

One common approach is to utilize a -integrate flag in main:

var runIntegrationTests = flag.Bool("integration", false
    , "Run the integration tests (in addition to the unit tests)")

This flag can be used to skip integration tests when running go test. However, it requires manually adding an if statement to the beginning of each integration test:

if !*runIntegrationTests {
    this.T().Skip("To run this test, use: go test -integration")
}

Alternative Solutions:

Another option suggested by @Ainar-G is to employ build tags to select which tests to run:

// +build integration

// ... Integration test code ...

This approach allows you to call go test -tags=integration to specifically run integration tests. Similarly, you can specify // build !unit to default to running integration tests and disable them with go test -tags=unit.

Additional Considerations:

• When using build tags, ensure that the // build comment is the first line in the file with a blank line following it.
• Build tags cannot contain dashes, so use underscores instead (e.g., // build unit_tests instead of // build unit-tests).
