用银杏故障测试两个字符串

Question

首先，我想告诉你，我对 Go 非常陌生，而且我来自 Python。话虽如此，我可以继续解决我的问题。我遇到以下问题：

cacciald@cacciald-Lenovo-G470:~/workspace/gopath/src/github.com/lcacciagioni/bosh_web_console/executor$ go test

Running Suite: Executor Suite

=============================

Random Seed: 1409854483

Executor

/home/cacciald/workspace/gopath/src/github.com/lcacciagioni/bosh_web_console/executor/executor_test.go:21

  Should execute a command [It]

  /home/cacciald/workspace/gopath/src/github.com/lcacciagioni/bosh_web_console/executor/executor_test.go:20

  Expected

      <string>: Hello World

  to be equivalent to

      <string>: Hello World

Summarizing 1 Failure:

[Fail] Executor [It] Should execute a command

FAIL

exit status 1

FAIL    github.com/lcacciagioni/bosh_web_console/executor       0.019s

这是代码：

// Package executor will provide a way to execute console commands in our

// Operative System.-

package executor

import (

        "bytes"

        "log"

        "os/exec"

)

func Runner(command, params string) string {

        cmd := exec.Command(command, params)

        var out bytes.Buffer

        cmd.Stdout = &out

        err := cmd.Run()

        if err != nil {

                log.Fatal(err)

        }

        return out.String()

}

这是我的简单测试：

package executor_test

import (

        . "github.com/lcacciagioni/bosh_web_console/executor"

        . "github.com/onsi/ginkgo"

        . "github.com/onsi/gomega"

)

var _ = Describe("Executor", func() {

        var (

                cmd    string

                params string

        )

如果有人能告诉我为什么这不起作用，那就太好了！！！

Answer 1

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