Testing two strings with ginkgo trouble
问题
首先,我想告诉你,我对Go语言非常陌生,我之前是用Python的。说完这个之后,我可以继续说我的问题。我遇到了以下问题:
cacciald@cacciald-Lenovo-G470:~/workspace/gopath/src/github.com/lcacciagioni/bosh_web_console/executor$ go test

FAIL

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
)
It("Should execute a command", func() {
cmd = "echo"
params = "Hello World"
Expect(Runner(cmd, params)).To(BeEquivalentTo(params))
})
})
如果有人能告诉我为什么这不起作用,那就太好了!

First of all I want to tell you that I’m very new at go and that I came from Python. Having saying that than I can continue with my problem. I’m having the following trouble:

Here is the code:
// Package executor will provide a way to execute console commands in our

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()
}
And here is my simple test:
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
)
It("Should execute a command", func() {
cmd = "echo"
params = "Hello World"
Expect(Runner(cmd, params)).To(BeEquivalentTo(params))
})
})
If some can tell me why this is not working that will be great!!!

得分: 5
你忘记了echo
的\n
。
这个是正确的写法:
var _ = Describe("Executor", func() {
var (
cmd string
params string
)
It("应该执行一个命令", func() {
cmd = "echo"
params = "Hello World"
Expect(Runner(cmd, params)).To(BeEquivalentTo(params + "\n"))
})
})
英文:
You forgot the \n
of echo
.
this works fine:
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"))
})
})
