Function VerifyTestMain

testmain.go:52–69

VerifyTestMain can be used in a TestMain function for package tests to verify that there were no goroutine leaks. To use it, your TestMain function should look like: func TestMain(m *testing.M) { goleak.VerifyTestMain(m) } See https://golang.org/pkg/testing/#hdr-Main for more details. This w

(m TestingM, options ...Option)

// This will run all tests as per normal, and if they were successful, look
// for any goroutine leaks and fail the tests if any leaks were found.
func VerifyTestMain(m TestingM, options ...Option) {
	exitCode := m.Run()
	opts := buildOpts(options...)

	var cleanup func(int)
	cleanup, opts.cleanup = opts.cleanup, nil
	if cleanup == nil {
		cleanup = _osExit
	}
	defer func() { cleanup(exitCode) }()

	if exitCode == 0 {
		if err := Find(opts); err != nil {
			fmt.Fprintf(_osStderr, "goleak: Errors on successful test run: %v\n", err)
			exitCode = 1
		}
	}
