		return
	}

	_, _, err = dbContainer.Exec(

func (itr *IntegrationTestRunner) InitAndRun() error

InitAndRun combines Init() and Run() calls for convenience.

func (*IntegrationTestRunner) Run 

func (itr *IntegrationTestRunner) Run() error

Run starts test workflow.

Workflow steps: 1. Run all preSetup steps 2. Build test binary 3. Start test binary in background 4. Execute test function 5. Cleanup resources

The contents of above steps will depend on given options.

type Opt 

type Opt func(*IntegrationTestRunner) error

Opt is option type for IntegrationTestRunner.

func OptBase 

func OptBase(base string) Opt

OptBase sets execution base path IntegrationTestRunner. OptBase should be usually the first option when passing options to NewIntegrationTestRunner.

func OptBuildArgs(args ...string) Opt

OptBuildArgs adds args to build arguments for test binary.

func OptBuildEnv 

func OptBuildEnv(env ...string) Opt

func OptFuncRunner added in v1.4.3 

func OptFuncRunner(fn func() error) Opt

OptFuncRunner allows wrapping any function as testRunner function. This can be useful injecting code between ready and test code. Example TestMain: 

func TestMain(m *testing.M) {
	itr := it.NewIntegrationTestRunner(
		it.OptBase("../"),
		it.OptTarget("./cmd/app"),
		it.OptCompose("docker-compose.yaml"),
		it.OptWaitHTTPReady("http://127.0.0.1:8080", time.Second*10),
		it.OptFuncRunner(func() error {
			if err := initStuff(); err != nil {
				return err
			}
			if code := m.Run(); code != 0 {
				return errors.New("tests have failed")
			}
			return nil
		}),
	)
	if err := itr.InitAndRun(); err != nil {
		log.Fatal(err)
	}
}

Before using this pattern be sure to read how TestMain should be used!

func OptRunEnv 

func OptRunEnv(env ...string) Opt

OptRunEnv adds env to test binary's run env.

func OptTarget 

func OptTarget(target string) Opt

OptTarget sets path to compilation target.

func OptTestFunc 

func OptTestFunc(t *testing.T, fn func(*testing.T)) Opt

OptTestFunc allows wrapping testing.T into IntegrationTestRunner. Example TestApp: 

func TestApp(t *testing.T) {
	itr := it.NewIntegrationTestRunner(
		it.OptBase("../"),
		it.OptTarget("./cmd/app"),
		it.OptCompose("docker-compose.yaml"),
		it.OptWaitHTTPReady("http://127.0.0.1:8080", time.Second*10),
		it.OptTestFunc(t, testApp),
	)
	if err := itr.InitAndRun(); err != nil {
		t.Fatal(err)
	}
}

func testApp(t *testing.T) {
	// run tests here
}

This pattern allows setting the env for each test separately.

func OptTestMain 

func OptTestMain(m *testing.M) Opt

OptTestMain allows wrapping testing.M into IntegrationTestRunner. Example TestMain: 

func TestMain(m *testing.M) {
	itr := it.NewIntegrationTestRunner(
		it.OptBase("../"),
		it.OptTarget("./cmd/app"),
		it.OptCompose("docker-compose.yaml"),
		it.OptWaitHTTPReady("http://127.0.0.1:8080", time.Second*10),
		it.OptTestMain(m),
	)
	if err := itr.InitAndRun(); err != nil {
		log.Fatal(err)
	}
}

Before using this pattern be sure to read how TestMain should be used!

func OptWaitHTTPReady 

func OptWaitHTTPReady(url string, timeout time.Duration) Opt

OptWaitHTTPReady expects 200 OK from given url before tests can be started.

type PreHandler 

type PreHandler interface {
	Run() error
	Stop() error
}

PreHandler is used for setting up pre conditions for test. Run() allows to perform setup before tests and Stop() the cleanup after the tests.
