I am trying to write Robot Framework tests using Visual Studio Code. Everything seems promising otherwise, but I am not able to get environment variables passed to the test execution runs no matter what I try.

I have a Python library accessed from my test cases that looks up values in os.environ. I need to populate this somehow.

I have a launch.json configuration of type robotframework-lsp (Robot Framework Language Server), but at least the env parameter does nothing. Likewise having an envFile does nothing.

I'm a bit of a VSCode beginner and the earlier responses I have been able to google seem confusing.
