Hi! If you reload your vs code window it should fix the problem. You can find a command to do so in the command palette "developer: refresh window"

[Saran33]

Facing the same issue. "developer: relaod window" doesn't resolve it for me. In one of my workspaces, the "Python tests" tab is duplicated, with one working and one showing the above error message. In another workspace, it's the exact same error as above (with no duplicate tab)

[grumBit]

I'm also having the same problem. Running "developer: reload window" didn't help either.

[grumBit]

After messing about in settings.json, I got it to work by setting "python.testing.unittestEnabled": false (it had been true).

These are all the settings related to testing in my settings.json;

  "python.analysis.enablePytestExtra": true,
  "python.analysis.enablePytestSupport": true,
  "python.testing.pytestEnabled": true,
  "python.testing.unittestEnabled": false,
  "testing.automaticallyOpenPeekView": "never",
  "testing.defaultGutterClickAction": "debug",

I'm guessing the last two have no impact on this problem. However, I've no idea how the first four may interact with one another. All I do know is setting unittestEnabled to false got it working on my machine.

[eleanorjboyd]

Hi! For these two settings- one must always be true while the other is false, maybe thats why it helped in your scenario?

"python.testing.pytestEnabled": true,
  "python.testing.unittestEnabled": false,
