Unit tests

Overview

We use the standard golang testing environment.

The following conventions are used:

• White box unit tests: Tests for internal functionality are placed in files
• Black box unit tests: Tests for public interfaces are placed in files with <package name>_test.go and belong to the package <package_name>_test. There only exists one package test file per package.
• Integration tests: Tests that use multiple componenents are placed in a package test file. These are named <package name>_test.go and belong to the package <package_name>_test.
• Test assets: Any required files are placed in a directory ./testdata within each package directory.

Executing tests

Visual Studio Code has a very good golang test integration. For debugging a test this is the recommended solution.

The Makefile provided by us has a test target that executes:

> go clean -testcache
> go build ./...
> go vet ./...
> go test ./...

Of course the commands can also be used on the command line. For details about golang testing refer to the standard documentation:

• Testing package
• go test command
