[QGIS-Developer] compare failing/succeeding CI builds (how to?)

My long-standing PR about preventing testsuite run from changing
files in source tree is currently having a Travis failure which
seems to start with:


Trying to understand what's going wrong with that test I see a lot
of warnings/errors being printed, like:

  GEOS exception: IllegalArgumentException: Points of LinearRing do not form a closed linestring
  ERROR 6: EPSG PCS/GCS code 7992 not found in EPSG support files.  Is this a valid EPSG coordinate system?

And eventually the actual failure printed in yellow:

	FAIL: test_algorithms:20
	'Find projection', {'algorithm': 'qgis:findprojection', 'name': 'Find projectio (__main__.TestQgisAlgorithms3)
	Traceback (most recent call last):

	AssertionError: 9 != 8

Now, as the test name mentions "projection" and one of the earlier errors are
about projections, I wanted to compare the failing run with the successful run
but the successful run is silent so I cannot compare. 

Would it make sense to enable verbosity on Travis for tests or should
I create a fake PR just for the sake of seeing those logs ?

Or more simply, can any other developers successfully running that
test let me know if those messages are printed ?

Thank you !
