This is quite possible: Git has a command, `git merge-base`, which can be used to figure out the relation between two branches you're interested in. In particular, a call

  $ git merge-base --fork-point test release

should print the SHA-1 name of the last commit both branches share with each other (before their histories have diverged) and exits with status code 0. Otherwise ("test" was not forked off "release") the command would print nothing and exit with status code 1.

I would suggest to read [1] to get better understanding of what it does.
