[6.x] Add new assertions assertSeeEmptyTextIn() and assertDontSeeEmptyTextIn()

[u01jmg3]

Sometimes it is helpful to check that a selector has some text (or conversely has no text) particularly when the value of the text is dynamically populated. This means it's less about asserting what the value of the text is but rather that there is some text (i.e. the contents of the selector is not empty).

This is where assertSeeEmptyTextIn() and assertDontSeeEmptyTextIn() comes into play.

Can't you pass an empty string to assertSeeIn and assertDontSeeIn?

[u01jmg3]

@taylorotwell: nope, assertSeeIn() and assertDontSeeIn() both use Str::contains(). This means you cannot check if a string is empty as it will always return false (as empty needles are discarded).

dump(Str::contains('text', '')); // false

dump(Str::contains('', '')); // false

@driesvints: any chance this can be looked at again? Apologies but I don't know what the procedure is for getting Taylor to take another look at a closed PR once he's made a comment.

I've given an explanation above as to why I believe assertSeeIn() and assertDontSeeIn() can't be used for checking if a selector has empty text or not. Unless I'm missing something...

[driesvints]

Re-opened this for Taylor to review.

Renamed to assertSeeAnythingIn and assertSeeNothingIn.
