首先，我想告訴你，我對 Go 非常陌生，而且我來自 Python。話雖如此，我可以繼續解決我的問題。我遇到以下問題：cacciald@cacciald-Lenovo-G470:~/workspace/gopath/src/github.com/lcacciagioni/bosh_web_console/executor$ go testRunning Suite: Executor Suite=============================Random Seed: 1409854483Will run 1 of 1 specs?

"github.com/lcacciagioni/bosh_web_console/executor" . "github.com/onsi/ginkgo" . "github.com/onsi/gomega")var _ = Describe("Executor", func() { var ( cmd string params string )如果有人能告訴我為什么這不起作用，那就太好了?。。?

你忘了\n的echo。
這工作正常：
var _ = Describe("Executor", func() {
var (
cmd string
params string
)
It("Should execute a command", func() {
cmd = "echo"
params = "Hello World"
Expect(Runner(cmd, params)).To(BeEquivalentTo(params + "\n"))
})
})
