In
.travis.yml
, the versions ofcoveralls
andpytest-cov
were unconstrained, creating a risk of failure in Travis CI builds if an incompatible version ofpytest-cov
orcoveralls
is released.As suggested in #89, use
pip-tools
to address this risk. The dependencies for coverage testing are inrequirements-cov.in
. The frozen set of packages is inrequirements-cov.txt
, compiled forpython 2.7.
This is only for coverage testing, since
pip-tools
doesn't handle relative paths and a minimal environment can help detect undeclared dependencies.
