👆 Easily create and insert coverage badge (or any other badge) in your readme with go
Using https://shields.io, the executable will generate a coverage badge based on the coverage output. The badge will be inserted on the second line of the readme if it doesn't exist, and will be updated if already present.
How to use
Install the executable
go install github.com/AlexBeauchemin/gobadge@latest
Make sure you generate a coverage file with your total coverage, something like
go test ./... -covermode=count -coverprofile=coverage.out fmt
go tool cover -func=coverage.out -o=coverage.out
Your output should looks like this, with the total as the last line
...
github.com/AlexBeauchemin/go-coverage-badge/gobadge.go:36: retrieveTotalCoverage 87.5%
github.com/AlexBeauchemin/go-coverage-badge/gobadge.go:53: updateReadme 80.0%
total: (statements) 67.4%
Then run the executable
gobadge -filename=coverage.out
