Type: Bug

Behaviour

Expected vs. Actual

For settings.json

{
"python.testing.pytestArgs": ["-m", "lazy"]
}

Expect to see vscode to run pytest with argument in TEST RESULT UI

Running test with arguments: --rootdir /home/vdc/git/six --override-ini junit_family=xunit1 --junit-xml=/tmp/tmp-1147287WvATg175YF9w.xml -m lazy

But, -m is gone

Running test with arguments: --rootdir /home/vdc/git/six --override-ini junit_family=xunit1 --junit-xml=/tmp/tmp-1147287NQVjhdMkoSyI.xml

However, if you do something like that, it will work

{
"python.testing.pytestArgs": ["-m lazy"]
}

Steps to reproduce:

1. Set -m in the settings.json

{
"python.testing.pytestArgs": ["-m", "lazy"]
}

1. Run the vscode test

Personally, I clone a open source project six to replicate this issue. HOpefully, this can be replicated with any python project
