Hi while trying to build the doc i encountered several issues.

Here is what i have done so far :

• make directive to fetch all branches (thanks to https://gist.github.com/grimzy/a1d3aae40412634df29cf86bb74a6f72 https://stackoverflow.com/a/10312587)
• make directive to failfast on lastfailed tests.
• Xfail some tests but there seems so be missing branches.

Please let me know if on pushes the missing branches to that i can redo the test and fix it locally then improve this PR.
