gocov

Exclude some code from test coverage reports

• Originally github.com/dave/courtney
• Main differences
  • gocov does NOT implicitly exclude any code
  • gocov prints not-covered lines in a format which is understandable by VS Code:

The following lines are not tested:
./context.go:47:2
./context.go:102:101
./ebnf.go:105:18
./ebnf.go:114:17
./ebnf.go:118:19
./ebnf/ebnf.go:41:26

Quick start:

• Install: go install github.com/heeus/gocov@latest
• Exclude code from test coverage:
  • Exclude the rest of the code block forever: // notest
  • Exclude the rest of the code block due to lack of time: // notestdept
• Show coverage-excluded code:
  • Excluded by // notest: gocov notest
  • Excluded by // notestdept : gocov notestdept
• Run tests and show uncovered lines:
  • Current package: gocov .
  • Current package + sub-packages: gocov ./...
  • Default (if nothing specified): ./...
• Verbose mode
  • Show output from the go test -v: gocov -v

Exclusion nuances

func foo() {
  fmt.Println("foo 1")
  fmt.Println("foo 2")
  // notest
  fmt.Println("foo 3") // excluded
  fmt.Println("foo 4") // excluded
}

func foo() {  
  fmt.Println("foo 1")
  fmt.Println("foo 2")
  {
    // notest
    fmt.Println("foo 3") // excluded
  }
  fmt.Println("foo 4")
}
