Allow for setting up a debug configuration for tests

Environment data

VS Code version: 1.18.1
Python Extension version: 0.8.0
Python Version: 3.6
OS and version: Windows 10 falls update

Actual behavior

"Step into" when debugging does not let me go inside a lib installed in the venv (not the current personal code)

Expected behavior

"Step into" let me step into whatever code (mine or dependencies).

Steps to reproduce:

• Place a breakpoint on a requests.get
• Step into

Logs

N/A

PTVS has an option for that, and possible in PyDev (but full disclosure it was a long time ago for this one...)

@lmazuel this is possible today.
Please try the following and let me know how it goes.

• Open your launch.json,
• find the relevant launch configuration
• add the entry DebugStdLib into the array debugOptions.

Please note, this is only an example, all you need to do is add DebugStdLib into the existing list:

"debugOptions": [
    "RedirectOutput","DebugStdLib"
],

Please let me know how this goes.

Hi the "Debug" button with pytest enabled":

So I don't have a launch.json. Have I?

[DonJayamanne]

Aah, you're debugging a unit test. That's new information.
Currently we don't support debugging non-user code when debugging unit tests.
That would be a new feature.

Sorry, didn't realize it was relevant information :/

I tried using the "Python" launcher and it works! At least I have a workaround when needed in the meantime. Thanks!
