odstasktest

Overview ¶

Package odstasktest implements ODS Pipeline specific functionality to run Tekton tasks in a KinD cluster on top of package tektontaskrun.

odstasktest is intended to be used as a library for testing ODS Pipeline tasks using Go.

Example usage:

package test

import (
	"log"
	"os"
	"path/filepath"
	"testing"

	ott "github.com/opendevstack/ods-pipeline/pkg/odstasktest"
	ttr "github.com/opendevstack/ods-pipeline/pkg/tektontaskrun"
)

var (
	namespaceConfig *ttr.NamespaceConfig
	rootPath        = "../.."
)

func TestMain(m *testing.M) {
	cc, err := ttr.StartKinDCluster(
		ttr.LoadImage(ttr.ImageBuildConfig{
			Dockerfile: "build/images/Dockerfile.my-task",
			ContextDir: rootPath,
		}),
	)
	if err != nil {
		log.Fatal("Could not start KinD cluster: ", err)
	}
	nc, cleanup, err := ttr.SetupTempNamespace(
		cc,
		ott.StartNexus(),
		ott.InstallODSPipeline(),
		ttr.InstallTaskFromPath(
			filepath.Join(rootPath, "build/tasks/my-task.yaml"),
			nil,
		),
	)
	if err != nil {
		log.Fatal("Could not setup temporary namespace: ", err)
	}
	defer cleanup()
	namespaceConfig = nc
	os.Exit(m.Run())
}

func TestMyTask(t *testing.T) {
	if err := ttr.RunTask(
		ttr.InNamespace(namespaceConfig.Name),
		ttr.UsingTask("my-task"),
		ttr.WithStringParams(map[string]string{
			"go-os":       runtime.GOOS,
			"go-arch":     runtime.GOARCH,
		}),
		ott.WithGitSourceWorkspace(t, "../testdata/workspaces/go-sample-app"),
		ttr.AfterRun(func(config *ttr.TaskRunConfig, run *tekton.TaskRun) {
			ott.AssertFilesExist(
				t, config.WorkspaceConfigs["source"].Dir,
				"docker/Dockerfile",
				"docker/app",
			)
		}),
	); err != nil {
		t.Fatal(err)
	}
}
