Regex for Gitlab CI Test coverage parsing

Question

I have been struggling to find a regular expression that will work in the "Test coverage parsing" input on the "CI/CD Pipelines" page. It doesn't help that the examples show inconsistent examples, i.e. some escape parenthesis and other don't, same with percent symbols, some capture the explicit result in $1, etc. Anyway, here is my text - whats the regex?

CI Badge:

![coverage](https://gitlab.com/mycompany/master/badges/master/coverage.svg?job=coverage)

Output text:

Unit test coverage:
   10.01% blocks
   10.01% lines

Tried so far: (added the slashes simply to represent the space at front or regex)

/ \(\d+\.\d+\%\) blocks/
/ (\d+\.\d+\%) blocks/
/ (\d+\.\d+%) blocks/
/ (\d+\.\d+)% blocks/

Answer 1

There is a useful Ruby regex web page.

I didn't not help for me with my GitLab code coverage parsing. I think it is because there seems to be a bug registered for a regex problem in GitLab. https://gitlab.com/gitlab-org/gitlab-ce/issues/21495

Answer 2

This regex should grab the blocks coverage:

^\s*(\d+(?:\.\d+)?%)\s*blocks

If you want to grab the line coverage instead then use this:

^\s*(\d+(?:\.\d+)?%)\s*lines

GitLab adds the leading and trailing / automatically so you don't need to add them to your regex.

For future reference, GitLab is written in Ruby so you can test this regular expression in Ruby over at rubular.com
