A customer recently emailed me asking why Object Test Bench doesn't work for Web projects and it seems there isn't any documentation on this limitation anywhere. In short, Object Test Bench (OTB) does *not* work with Web projects. Due to a bug, OTB still shows as being an enabled feature for Web projects when it should really be disabled. The OTB team is looking to update the docs to call out this limitation so you don't rack your brain trying to figure out what's wrong...
