How to use the "gobco" to show the branch coverage of any test.go file #15

Closed BattleBird closed 4 years ago

BattleBird commented 4 years ago

Dear developer,

  I have a requirement. I want to use the following runtime_test.go file to measure the branch coverage of this test unit. The runtime_test.go is put in the

go/src/github.com/ethereum/go-ethereum/core/v.m/runtime path, this is the go-ethereum project. I just can use the "go tool cover" to measure the statements coverage. I don't know how to use the "gobco" tool to measure the branch coverage.

`package runtime

import ( "fmt" "github.com/ethereum/go-ethereum/common/hexutil" "testing"

"github.com/ethereum/go-ethereum/common"

)
