Question

我有一套测试，使用GoConvey和Go 1.3.1在本地工作得很好。但是当我用Jenkins触发构建时，Go 1.3.1也是如此，我得到了Goconvey的恐慌，这与我在测试中使用的go例程有关。

可以在这里看到测试：

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：

Hint: Perhaps you meant to use `Convey(..., func(c C){...})` ?

Answer 1

因为您尝试从另一个goroutine执行断言，所以您需要在C签名中使用最近添加的上下文结构（func()），然后调用{{1}离开那个背景。这是您的版本稍作修改：

So

这是拉request #264的结果。

Answer 2

此例外由context.go#mustGetCurrentContext()启动您可以在story_conventions_test.go#TestFailureModeNoContext

中看到触发相同异常的测试

Convey("Foo", t, func() {
    done := make(chan int, 1)
    go func() {
        defer func() { done <- 1 }()
        defer expectPanic(t, noStackContext)
        So(len("I have no context"), ShouldBeGreaterThan, 0)
    }()
    <-done
})

从测试示例中，如果看起来在Convey测试中从goroutine中调用goroutine会触发无上下文恐慌。

由于Jenkins从goroutine启动测试，这可能解释了为什么GoConvey测试失败（即使它在Jenkins之外直接调用go test时运行）

Goconvey引起恐慌与詹金斯的常规
