By calling e.g. forceHappoScreenshot('empty') you can split up a
component in multiple steps with screenshots happening in each step.
Implementation details:
An error is thrown when you call forceHappoScreenshot, only in a Happo
environment. This will tell happo to take the screenshot. To get to the
next step in the play function, we restart execution. This means that
the play function gets invoked several times, halting at the "next" step
each time.
