This line is fine, but I don't believe the abspath is necessary. Normally:

os.path.join(os.path.dirname(__file__), 'mpl.rc')

Would suffice.


def test_rcparams():

usetex = mpl.rcParams['text.usetex']
linewidth = mpl.rcParams['lines.linewidth']

# test context given dictionary
with mpl.rc_context(rc={'text.usetex': not usetex}):
assert mpl.rcParams['text.usetex'] == (not usetex)
assert mpl.rcParams['text.usetex'] == usetex

# test context given filename (mpl.rc sets linewdith to 33)
with mpl.rc_context(fname=fname):
assert mpl.rcParams['lines.linewidth'] == 33
assert mpl.rcParams['lines.linewidth'] == linewidth

# test context given filename and dictionary
with mpl.rc_context(fname=fname, rc={'lines.linewidth': 44}):
assert mpl.rcParams['lines.linewidth'] == 44
assert mpl.rcParams['lines.linewidth'] == linewidth

# test rc_file
mpl.rc_file(fname)

This will have a global effect on the tests and will need to be undone at the end of execution. Perhaps:

try:
    mpl.rc_file(fname)
    assert mpl.rcParams['lines.linewidth'] == 33
finally:
    linewidth = mpl.rcParams['lines.linewidth']

assert mpl.rcParams['lines.linewidth'] == 33
