Placing conftest file in the project causes results in failure while using pytest

Issue Type: Bug Open the project in vscode. Download the dependencies mentioned in the pyproject.toml file. Run the test present in the tests folder.

Expected : Test should run and the status of the test should be reflected. Actual : Test runs but we get an error message saying “Error: TypeError: Cannot read property ‘testsuites’ of null”. Also below errors are observed.

This makes it difficult to know the status of any test.

Sample code to reproduce the issue. pytest-test-runner-check.zip

Please note : Removing the conftest.py file solves this issue. Issue persist even if we move the conftest.py file in the root of the project.
