Allow to change coverage data file location in settings

[andreihes]

I have a need to override a coverage data file location in python project. So I use:

[run]
data_file = .data/coverage.data

or similar in .coveragerc. Once changed then VS Code is not able to render TEST COVERAGE anywhere on the UI.

It would be nice to see some setting like:

"python.testing.coverageFile": "${workspaceFolder}/.data/coverage.data"

to set it on demand instead of default .coverage one.

Yes valid request. From what I can see this would just require allow coverage.Coverage() to have a data_file (FilePath | DefaultValue | None) value here:

vscode-python/python_files/vscode_pytest/__init__.py

Lines 444 to 445 in 92cc4ed

	cov = coverage.Coverage()
	cov.load()

. With the setting passing an env var that could be read and substituted if it exists.
