Subject: [PATCH] Allow test repos to be kept locally
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We no longer assume that the test repos don’t exist when we run run-tests.sh. This allows developers to choose to keep them, to allow them to run the tests more quickly.

- Add the test repos to the .gitignore.
- Check if the directory for each repo already exists, before trying to clone it.
- Do a `git pull` for each repo, to ensure that existing copies of repos are up-to-date.
