func CheckNotParallel ¶

func CheckNotParallel(t testing.TB)

CheckNotParallel checks if t.Parallel() was not called on the current test. There's no public method to check this, so we use reflection to check the internal field set by t.Parallel() https://github.com/golang/go/blob/8e658eee9c7a67a8a79a8308695920ac9917566c/src/testing/testing.go#L1449

Since this is not a public API, it might change at any time.
