- When $WINEPREFIX is not set, create a prefix directory in behalf of the user with the name being the ulwgl id. Currently, we create the directories as ~/Games/ULWGL/<ULWGL_ID>. In effect, the only required environment variable will be $GAMEID.
- Arguably the most important test of this test suite as we do **not** want to remove files that isn't ours. We test both the positive and negative case. In the latter, the state of the cache or Steam compat should be left the same state as it was before executing the function when passed files that do not exist.
- Also, update the test to check for expected environment variables in the dictionary. Notably, when a valid ULWGL_ID is set, the STEAM_COMPAT_ID and related env var should be the stripped ULWGL_ID.
- Before, the executable and its options were joined as a single string to be executed. Instead, prefer separating them as distinct arguments. As a result, the command as an Array becomes something like:
['/home/foo/.local/share/ULWGL/ULWGL', '--verb', 'waitforexitandrun', '--', '/home/foo/GE-Proton8-30/proton', 'waitforexitandrun', '/home/foo/foo.exe', '-foo', '-bar', '-baz']
