How do you perform a compression test with a DI cassette?

[QWICSVT]

Wouldn't the fact that our vehicles are equipped with a DI casette rather than a more common plug wire set-up make it more difficult to perform a standard compression test? How does one get around this fact for a DIY diagnosis?

Just un bolt and lift off the cassette, its out the way you've then got 4 plugs to work with doing the test in the usual way.
