I use the pytest-sugar to prettify my tests but need to disable it to have a more standard output to have full file paths instead of coloured shortened ones. This need the -p no:sugar option to be given.

Also many other options need arguments because aren't simple flags, like -c config.file.

When running a specifc test (e.g. clicking in "Run test" or "Debug test" above test definition), the settings.unitTest.pyTestArgs is filtered to remove any argument that doesn't starts with a -, which fails when running options like -p or -c.

The only ways I figure out to work around this is:

• Remove this filter. Not wanted, because would force users to have a setup.cfg or something like it;
• Hardcode all pytest options;
• Separate the positional file_or_dir argument from the rest. E.g. pyTestFilesOrDirs from pyTestArgs. This is my personal choice.

I would submit a pull requests, but the contributing guide says to open a issue first.

Environment data

• VS Code version: 1.20.1
• Extension version 2018.2.1 and master

Actual behavior

Simply put, many pytest options aren't supported when running specific tests

Expected behavior

Steps to reproduce:

1. Use the following setting:

{
    "python.unitTest.pyTestArgs": ["-p", "no:sugar"]
}

2. Click on "Debug test".
