What the tube checks like is not quite everything especially when it comes to oscillators.
Once it starts though it will oscillate forever without problems - it is the start-up condition that is finicky. This is where the tube might potentially influence the behavior of the whole circuit.
You tester checks for certain parameters, it does not check for the whole performance.
