E2E testing

$ source .ate-dev-env.sh
$ go test -v ./internal/e2e/suites/... -args -e2e

Principles

Keep it simple -- use go test for the harness.
e2e tests live under internal/e2e/suites/<suite>
Each suite should implement TestMain using e2e.RunTestMain()
- e2e tests will be skipped for ordinary unit tests unless the -e2e flag is set e.g. go test ./internal/e2e/suites/... -args -e2e
Helper libraries live under internal/e2e
Setup and Teardown are on a per-component basis and the component's author's responsibility.

Preconditions

The e2e tests assume you have a cluster setup with hack/install.sh.

Creating a new test suite

Copy testmain_test.go from internal/e2e/suites/example into your new suite. It will look like this:

func run(m *testing.M) int {
	Setup()
	defer Teardown()
	// return allows the deferred Teardown to run.
	return e2e.RunTestMain(m)
}

func TestMain(m *testing.M) { os.Exit(run(m)) }

This will handle the standard flags and checks for running an e2e test suite.
