This tries to set up checklist for list views, detail views, shared actions, and new/edit forms.

I would like to also add one thing - when you are waiting for API response, that may not be enough, because items must be then rendered and this may cause sporadic failure in situation when you are looking for something that should not exist (for example using contains). Because cypress may (or may not, depends on randomized timing) run before rendering and it then sees that element dont exist, however element may appear after rendering. When you are testing that element do exist, this problem does not appear, because if the contains is not valid (element is not rendered yet), cypres test it several times after several seconds until the element is rendered (to ensure page is in valid state). In this situation, test may fail only if rendering last more than several seconds, which will happen only in rare occasion. So to ensure correct and stable tests, you should use some contains for waiting for some element to be rendered (so it will wait for page render) before you do some test for 'should not exist' element. For example when testing elements in the list, first test the element that should be in the list, then element that should not be in the list.

The readme already says just waiting for the API is not enough, so this sounds like it's solved?

Or is there something I should change here?

(Also, this is not coming from this PR.)

I just wanted to point one problem that may be dangerous, when you "wait" for the render using contains(something).should.not.exists, this will not actualy wait for render, because it will not see the element in the current page state and return true immideately, then element appear in render. Whereas positive contains always wait several seconds if it not sees the element until element eventualy appear in render.

[himdel]

good point, adding a note about should.not.exist specifically 👍

I'll just merge this, it's a README change only, we can always update these later.
