As Kornel has explained:
There is an incompatibility between luainputenc.sty and ectaart.cls.
luainputenc.sty loads luatex.sty. Both files (luatex.sty and
ectaart.cls) define the latex-command \setattribute.
These tests should be inverted because the conflict may one day be
resolved at which point we can begin testing for regressions.
(This commit also rearranges the europeCV lines to below the
corresponding explanation comment.)
a) test export/templates/ectaart_pdf5 removed, because
of incompatibility between ectart.cls and luatex.sty
b) renamed some tests to reflect their purpose
tex2lyx2lyx/roundtrip/ => tex2lyx/cmplyx/
# the tests are comparing files written by lyx (not by tex2lyx)
autotests/ => keytest/
# we are testing reactions of lyx to some key strokes
c) add tests for lyx2lyx. This is rather rudimental, in that it only
checks for created output, error codes and error output.
d) use correct environment variable to set up the userdir for testing
