It will fail because no test will be run here you should add an else condition
Edit : As I said, see here : https://travis-ci.org/twbs/bootstrap/jobs/217986589

Subject: Re: [twbs/bootstrap] Fix #22332: Check if the scrollbar affects the document before running the padding tests (#22337)
There's no point running the test when no changes are made to the DOM. I will move the conditional outside and if that fails too I will remove the opening test altogether.

@Johann-S I modified the tests to check if the padding/margin is changed as expected, even if that is zero. Should no longer give errors, but please give it a try. You may want to clear the "changes requested" flag, since I forced a push on the previous commit to keep it clean. |

On macOS and mobile devices the scrollbar is not part of the document, but rather floats above it. This means that it does not affect body/fixed element padding and scrollbarWidth is equal to 0.
The problem in #22332 was caused by the fact that the test expected padding-right to be increased while opening a modal, but threw an error when it was not (because padding + 0 = padding).
To address the issue the following changes have been made:
