Basically, this creates a screenshot and throws tesseract at it to recognize the characters from the screenshot. In order to produce a result that is well enough, we're using lanczos scaling and scale the image up to 400% of its original size. This provides the base functionality for a new Machine method which will be called waitForText. I originally had that idea long ago when writing the VM tests for VirtualBox and Chromium, but thought it would be disproportionate to the case. The downside however is that VM tests now depend on tesseract, but given the average runtime of our tests it really shouldn't have a too big impact and it's only a runtime dependency after all. Another issue is that the OCR process takes quite some time to finish, but IMHO it's better (as in more deterministic) than to rely on sleep(). Signed-off-by: aszlig <aszlig@redmoonstudios.org> |
