`make tests` fails with another osquery process running.
The backing-store check happens after a config plugin is setUp and
the initial load occures. This may involve calls to cached keys, the
check should occur pre-config initialize.
There are a couple places where this was an issue.
The first place was in the filesystem plugin where it was only checked that it
existed, and not that it was an actual file.
The second was a lack of try and catch on the parse call in config.cpp.
Both of those issues are addressed in this diff.
Move /osquery/python_tests/* to /tools/tests
Move test_extensions process controls to test_base module
Use test_base.Testing to implement each module's main()
- This applies a default argparse with --build
- test_base.ARGS is the argparse-parsed namespace
- Use test_base.ARGS.build for the platform-specific dir
Move WatchdogTests to /tools/tests/test_watchdog.py
