Please find the attached patch to calculate code coverage if pgadmin code(python tests).
I have extended the existing testsuite to enable coverage. I have used python's coverage module.
Some useful commands:
before running the commands make sure you create .coveragerc file under /regression directory(details mentioned in README)
Run coverage
With all modules run 'python runtests.py --coverage --exclude feature_tests' With specific module run 'python runtests.py --pkg browser.server_groups.servers.tests --coverage'
