Without code lenses after running "Run All Unit Tests".

[linette-zyy]

Environment data

• VS Code version: 1.42.0-insider
• Extension version: 2020.1.56281-dev

Steps to reproduce:

1. Launch VSC and create python file named unit_test.py in folder1
   a. Clear the part of workspace configuration in setting.json
2. Enter below code:

import unittest

class PassingTests(unittest.TestCase):
    def test_passing(self):
        self.assertEqual(42, 42)
    def test_passing_still(self):
        self.assertEqual("silly walk", "silly walk")

class FailingTests(unittest.TestCase):
    def test_failure(self):
        self.assertEqual(42, -13)
    def test_failure_still(self):
        self.assertEqual("I'm right!", "no, I am!")    

3. Repeat step1,2 but in folder2
4. Run "Run All Unit Tests", ensure:
   a. triggers the prompt to configure the test runner
   a). Click "Enable and configure a test framework"
   b). Select "Unittest" and next ". Root directory"
   c). Select first test file name format

Expected behavior

Tests are discovered (as shown by code lenses on each test)

Actual behavior

Without code lenses.

This issue reproduced on Python2.7, Python3.7 and Anaconda environments.

Hi @linette-zyy 👋 Thank you for reaching out!

unittest will discover tests recursively as long as they are inside modules, so you need to add a __init__.py file to each folder containing tests for it to be discovered successfully (see this SO answer):

@kimadeline
1.method of add init.py only useful to python 3.7 , changed current environment to python 2.7, code lens will disappear and you can see my video of steps:
unittest.zip
2.the code lens of failed case was not 'X', it showed like below:

You need to reload the window for the code lenses to reappear (happens when switching interpreters).

You are correct, the icons were updated since the last release (#8486).
