I am trying to show the build status of my branch on that branch's readme.md.
https://mygitlab.com/<namespace>/<project>/badges/<branch>/coverage.svg
I tried this but branch place holder isn't getting evaluated.
You could create a README.md with the following for each branch
[![Coverage](https://gitlab.com/<namespace>/<project>/badges/<branch>/coverage.svg)](https://gitlab.com/<namespace>/<project>/)
for example:
Master Branch README.md
Other Branch README.md
