XF 1.2 Fill the forum with test data easily?

I'm working on a local install of XenForo while developing a in-depth theme but having a lot of difficulty in regards to testing the changes.

Is there an easy way to fill a XenForo install with a lot of test data instead of manually logging in -> Posting -> Repeat for each test user?

Even if it's just a case of having it randomly post from a randomly-registered 'user' with lipsum.
