I have set up a pipeline that generates some gitlab-ci configuration and than triggers all jobs defined in it. There are currently four jobs triggered and all run successfully:
Is the downstream job in a different repo? Do you have Settings → CI/CD Settings → General pipelines → Test coverage parsing set correctly, and in the right place?
The downstream jobs are not physical in any repository - they are generated on-the-fly by the projects “generate-config” job and then triggered for execution (screenshot 1; see also Parent-child pipelines | GitLab). But still they all work on the same repository. The test coverage parsing is also working (screenshot 2). It makes no difference if the regular expression is configured through the setting you mentioned or through the “coverage” keyword in the job configurations or by both means. It is always correctly extracted by the CI but never shown in the badges.
Oh, that’s annoying. I guess you could always write a script to parse the output yourself before it gets to the log, but that might be more trouble than it’s worth.
