comptest

comptest

API will be unstable until major release.

The package aims to make component testing easier by providing a set of helper functions.

• Build binary from your code and run it
• Inject migrations with seed data
• Run migrations up and down
• Wait for database, mocks and main service to be ready
• Prepare and use gcp pubsub. Send messages to pubsub.

Quickstart

Get package

go get github.com/ingridhq/comptest

And start using it:

func TestMain(t *testing.M) {
	// Initialize comptest lib.

	ctx, cancel := context.WithTimeout(context.Background(), 40 * time.Second)
	defer cancel()

	c := comptest.New(ctx)

	c.HealthChecks(
		waitfor.TCP(os.Getenv("PUBSUB_EMULATOR_HOST")),
	)

	c.BuildAndRun("../main.go", waitfor.HTTP(fmt.Sprintf("http://%s/readiness", cfg.ReadinessPort)))

	t.Run()
}

func Test_response(t *testing.T) {
	resp, _ := http.Get("http://localhost:8080/")

	if resp.StatusCode != http.StatusOK {
		t.Fatalf("unexpected status code : %v", resp.StatusCode)
	}
}

Full example can be found in _example directory. There you will learn how to use most of the package's functionality. You can run it with make.
