How to test for trailing whitespace?

[loziniak]

In #62 I encountered a problem. I have a whitespace before comments (line comment 1, 2 and 3), but cannot write tests, because Rubocop complains during CI. Is this possible to:

• turn off Rubocop trailing whitespace check

or

• have snippet extractor cut trailing whitespace?

This is a sample code for snippet-extractor test:

          x: 1 ; line comment 1
          y: 11
          x: 2   ;-- line comment 2
          x: 3		;@@ line comment 3

Rubocop complains for the expected part:

          x: 1 
          y: 11
          x: 2   
          x: 3

Mmm this is awry. The snippet extractor will always trim any whitespace from the lines (I have to double check but I'm quite sure the only thing it preserves are tabs/spaces at the start).

It rather seems a problem with Rubocop failing linting checks. Could you paste your error please? (Try first to check your other issue and limit your test to 10 lines to see if it keeps complaining and we can go from there)

#66 is fixed now, but here nothing changed.

In 0c374d9 I tried to get into account the fact, that Extractor will clear whitespace, but id didn't.

[joshiraez]

I'm quite sure this is a rubocop issue, but I think the extractor will remove any trailing whitespace at the right anyway, so you should be safe to remove those from the expected,

Oh wait, I just saw your commit. Let me take a look at this then
