func WaitFor

func WaitFor[T any](t *testing.T, timeout time.Duration, poll func() (T, error), check func(T) bool) T

WaitFor continuously calls poll until check returns true. It then polls for a little longer to make sure that poll still returns a value v such that check(v) is true. If the condition never happens, or the condition becomes true and then false, it invokes t.Fatal.

If poll returns an error, WaitFor calls Fatal.

WaitFor returns the last value that poll returned.
