Goverage is a JetBrains IDE plugin that displays inline code coverage for Go files based on the go test -coverprofile report.
It supports GoLand, IntelliJ IDEA Ultimate, and any JetBrains IDE with the Go plugin.

🚀 Usage

1. Generate a coverage profile in the root of your Go module:

   go test -coverpkg=./... -coverprofile=coverage.out

2. Open any .go file in your project.

3. You’ll see inline hints like:

   File Coverage: 91.75%
   Function Coverage: 85.00%
   

🛠️ Notes

• Coverage is resolved using the path format found in coverage.out, typically like:
  github.com/your/module/pkg/file.go
• The plugin reads the go.mod file to determine the module name.
• Only works with monorepos if go test and coverage.out are executed per-module.
• Coverage is computed based on Go’s coverprofile format, which counts covered statements, not lines.
• Integration tests might not hit every code path, even if the file is used indirectly.
• Some files may appear with partial coverage if branches or conditions are not fully executed.
