golang银杏测试包覆盖率

我有以下文件结构：

❯ tree
.
├── go.mod
├── go.sum
├── Makefile
├── p1
│   └── p1.go
└── tests
    └── integration
        └── integration_suite_test.go

3 directories, 5 files

p1/p1.go

❯ cat p1/p1.go
package p1

func MyTestFunction(s string) string {
        return "hello " + s
}

我从另一个目录的银杏测试中测试：

❯ cat tests/integration/integration_suite_test.go 
package integration_test

import (
        "testing"

        "example.com/test-ginkgo/p1"
        . "github.com/onsi/ginkgo/v2"
        . "github.com/onsi/gomega"
)

func TestIntegration(t *testing.T) {
        RegisterFailHandler(Fail)
        RunSpecs(t, "Integration Suite")
}

var _ = Describe("Testing external function", func() {
        _ = Context("from integration test", func() {
                It("and verify coverage", func() {
                        input := "test"
                        want := "hello " + input
                        got := p1.MyTestFunction(input)
                        Expect(got).To(Equal(want))
                })
        })
})

我通过以下方式执行案例：

$ ginkgo -r -v -race --trace --cover --coverprofile=.coverage-report.out --coverpkg=./... ./...

--coverpkg

❯ cat .coverage-report.out 
mode: atomic

--coverpkg
