Motivation
The strategy of passing the port to LSP reporter via environment variable is a bit weak. For example, if you reload VS Code and then proceed to run tests manually in a terminal that we set up, you will get a connection refused error because we never updated the port variable in that old terminal.
I think we can be a lot more reliable by writing the port to a file.
Implementation
Every workspace reports test results through the same port, so my idea is to write a temporary file with the port information that the LSP reporter can read on its own.
That way, every time the extension reloads, we update the port in the file and, every time the tests are executed (regardless if it's manual or through the explorer), we will read that value again ensuring that we're using the right port.
Finally, I noticed one more hurdle. When running tests manually through the terminal, we were receiving the connection okay, but there was no
runobject to use for reporting the items' statuses. We need to create arunobject on demand when not running through the explorer, otherwise the statuses won't appear as expected.
