How to set up and validate locally
Numbered steps to set up and validate the change are strongly suggested.
- Have a project configured with a .gitlab-ci.yml file and runner, if you don't have a project I recommend cloning the following project from Fabio's project list https://gitlab.com/fabiopitino/job-log-tester
- Create a merge request and while the pipelines are running you can test the MWPSorMerge when pipeline succeedsscenarios, to test theMTandMTWPS(Merge Trains) scenarios, see 3.
- To test merge trains go to Settings -> Merge Requestsand tickEnable merge results pipelinesandEnable merge trains, create a new pipeline for the previous merge request and play around with "Mr. Widget"
