First we'll update your local master branch. Go to your local project and check out the branch you want to merge into (your local master branch)
$ git checkout master
Fetch the remote, bringing the branches and their commits from the remote repository. You can use the -p, --prune option to delete any remote-tracking references that no longer exist in the remote. Commits to master will be stored in a local branch, remotes/origin/master

This test runner flushes the test db after all tests are run, and retains the schema (all tables will be truncated) | |
You can safely run all tests using --keepdb (recommended) parameter where in it will only keep the schema , but not the actual data | |
This saves times in frequent test runs as the entire test db schema doesnt have to be recreated every time | |
note that this will still apply newer migrations (if any) from last known point when the tests were run | |
if you actually want to retain test data, then do not use this test runner | |
