If the issue closing pattern is not present in the merge request description, the MR is not considered to the measurement time of the stage. |
 | Test      | Measures the median time to run the entire pipeline for that project. It's related to the time GitLab CI takes to run every job for the commits pushed to that merge request defined in the previous stage. It is basically the start->finish time for all pipelines. |
