I had the bad experience that this doesn't work on Windows: ```yaml - name: Run coverage run: go test -v -race -coverprofile=coverage.out -covermode=atomic ./... ``` Output: ``` no required module provides package .out; to add it: go get .out Error: Process completed with exit code 1. ``` But this works: ```yaml - name: Run coverage run: go test -v -race -coverprofile coverage.out -covermode atomic ./... ``` The only difference is that `=` is replaced with space. I suspect this is a PowerShell quoting issue.
