Sure! You can run go test -cover ./... in your terminal to see the coverage for all packages in your module.
What does the coverage report look like?
The coverage report shows which lines of code were executed during tests, highlighting covered lines in green and uncovered lines in red.
Is there a way to generate a detailed coverage report?
Yes, you can use go test -coverprofile=coverage.out followed by go tool cover -html=coverage.out to generate an HTML report.
