Windows filenames have backslashes, so we need to escape them, otherwise
shlex.split will delete them.
Also, we can't prodive our own executable on frozen tests.
pytest doesn't like test classes which define __init__, and pylint
doesn't like attributes defined outside __init__.
We can disable pylint's check, but we can't force pytest to accept our
test class...
The check `key.startswith('<') and key.endswith('>') is repeated many
times in code to check for a special key. Replace all these with a call
to the same function.
For some reason, when comparing the repr in the two processes, we get different
results on OS X and Windows:
- expected: "fünf"
- "f\xfcnf" coming back from the subprocess on OS X
- "fnf" on Windows
Instead we're comparing the json dump now, which should be more predictable.
There are a lot of problems and flakiness with using a real clipboard.
Instead we now have a :debug-set-fake-clipboard command to set a text, and use
logging when getting the contents.
Fixes#1285.
This broke the tests for older PyQt versions because the test had a
test_utils.Color(test_utils.Color(...)) object (double-wrapped), and the
comparisons failed there for some reason.
