pytest-cov detection assumes entry point name #25590
Description
Type: Bug
Behaviour
In python_files/vscode_pytest/init.py:
has_pytest_cov = early_config.pluginmanager.hasplugin("pytest_cov")
assumes that the plugin was loaded using its entry point name, but it can also be loaded via its module name:
[project.entry-points.pytest11]
pytest_cov = "pytest_cov.plugin"
This should be an easy fix to check for both, but I don't have time at the moment to look into how to test a patch for this in the repo, so filing an issue for this in case it is easier for someone else to address.
Thank you so much!
Steps to reproduce:
- Disable all plugin loading in pytest using --disable-plugin-autoload
- Load pytest-cov directly using -p pytest_cov.plugin
- Observe that test collections fails since it thinks pytest-cov isn't available.
