It includes Cleber's patch adding some basic Avocado tests and builds on that. The current draft is pretty janky: * The build rules to download and install the necessary pieces are messy * We create the Avocado job files from the exeter sources in the Makefile. Ideally Avocado would eventually be extended to handle this itself * The names that Avocado sees for each test are overlong * There's some hacks to make sure things are executed from the right working directory But, it's a starting point. Stefano, If you could look particularly at 6/22 and 22/22 which add the real tests for passt/pasta, that would be great. The more specific you can be about what you find ugly about how the tests are written, then better I can try to address that. I suspect it will be easier to actually apply the series, then look at the new test files (test/build/build.py, and test/pasta/pasta.py particularly). From there you can look at as much of the support library as you need to, rather than digging through the actual patches to look for that. Cleber, If you could look at 4..6/22 particularly to review how I'm connecting the actual tests to the Avocado runner, that would be helpful.
