See:

Not entirely sure I have the test environ set up correctly, but
  79% tests passed, 48 tests failed out of 231
isn't so bad as a starting point (I think...).

The following timed out:
PyQgsComposerHtml Failed  25m 30ms Completed (Timeout)

Most render test comparisons are close, excepting

qgis_composerlabeltest
http://dash.orfeo-toolbox.org/testDetails.php?test=41851057&build=231771
qgis_gradienttest
http://dash.orfeo-toolbox.org/testDetails.php?test=41851093&build=231771
qgis_composerpicturetest
http://dash.orfeo-toolbox.org/testDetails.php?test=41851065&build=231771

Also, about 50% of the Python test errors might be remedied with updating
to Py3 or some trivial module finding fixes.
