What did you do?

$ go test -count=1 -coverprofile coverage.out ./... -v -coverpkg=./...
$ go tool cover -func=coverage.out

Example file:

package errors

type CustomError1 struct {}

func (e *CustomError1) Error() string {
    return "error 1 description"
}

type CustomError2 struct {}

func (e *CustomError2) Error() string {
    return "error 2 description"
}

What did you expect to see?

gitlab.com/a-novel/tools/logs/internal/errors/errors.go:5:         CustomError1.Error                   100.0%
gitlab.com/a-novel/tools/logs/internal/errors/errors.go:11:        CustomError2.Error                   100.0%

What did you see instead?

gitlab.com/a-novel/tools/logs/internal/errors/errors.go:5:         Error                   100.0%
gitlab.com/a-novel/tools/logs/internal/errors/errors.go:11:        Error                   100.0%

Description

More a suggestion than an actual issue, but I think it would be nice if go tool cover could display methods receivers (when any) when logging results to console.

It will make output more readable and convenient for codes highly relying on interfaces and structs :)
