jenkins - Goconvey 在 Jenkins 上用 go routine 引起 panic

Question

我有一组使用 GoConvey 和 Go 1.3.1 的测试，在本地工作得很好。但是当我使用 Jenkins 触发构建时，也使用 Go 1.3.1，我从 Goconvey 那里得到了一个与我在测试中使用的 go 例程相关的 panic 。

测试可以在这里看到:

func TestListApplication(t *testing.T) {
    s := &Session{}
    s.Username = "foo"
    s.Password = "bar"
    ts := serveHTTP(t)
    defer ts.Close()
    s.Baseurl = ts.URL
    s.initialize()

    go func() {
        <-s.Comms.AppCount
    }()

    Convey("TestListApplication", t, func() {
        s.Comms.MainWaitGroup.Add(1)

        application := &Application{}
        err := json.Unmarshal(applicationJSON(), application)
        So(err, ShouldBeNil)

        revisions := &Revisions{}
        err = json.Unmarshal(revisionsJSON(), revisions)
        So(err, ShouldBeNil)

        var wg sync.WaitGroup
        wg.Add(1)
        go func() {
            defer wg.Done()
            line := <-s.Comms.Msg
            So(line, ShouldEqual, "3        admin       foo\n")
        }()
        s.listApplication(application, revisions)
        wg.Wait()
    })
}

这里的错误:

86 assertions thus far

..
88 assertions thus far

panic: Convey operation made without context on goroutine stack.
Hint: Perhaps you meant to use `Convey(..., func(c C){...})` ?

Answer 1

因为您正在尝试从另一个 goroutine 执行断言，所以您需要在 func() 中使用最近添加的上下文结构 (C)签名，然后从该上下文中调用 So。这是您稍作修改的版本:

Convey("TestListApplication", t, func(c C) {
    s.Comms.MainWaitGroup.Add(1)

    application := &Application{}
    err := json.Unmarshal(applicationJSON(), application)
    So(err, ShouldBeNil)

    revisions := &Revisions{}
    err = json.Unmarshal(revisionsJSON(), revisions)
    So(err, ShouldBeNil)

    var wg sync.WaitGroup
    wg.Add(1)
    go func() {
        defer wg.Done()
        line := <-s.Comms.Msg
        c.So(line, ShouldEqual, "3        admin       foo\n")
    }()
    s.listApplication(application, revisions)
    wg.Wait()
})

这是拉动的结果 request #264 .
