How to run unit tests for appengine go project
问题
我在~/Applications/google_appengine中有我的appengine SDK。
在Eclipse中，我设置了一个外部工具来运行开发服务器。它指向：
~/Application/google_appengine/dev_appserver.py
同样在Eclipse中（进入首选项），我设置了GOROOT指向
~/Application/google_appengine/goroot
现在，我正在尝试运行一些项目的单元测试。如果我使用常规的go安装（而不是appengine的），我会得到以下错误：
../../context/context.go:4:2: 无法在以下任何位置找到包“appengine”：
/usr/local/go/src/pkg/appengine（来自$GOROOT）
/Users/home/src/go/foodbox/src/appengine（来自$GOPATH）
../../context/data.go:4:2: 无法在以下任何位置找到包“appengine/datastore”：
/usr/local/go/src/pkg/appengine/datastore（来自$GOROOT）
/Users/home/src/go/foodbox/src/appengine/datastore（来自$GOPATH）
../../context/context.go:5:2: 无法在以下任何位置找到包“appengine/user”：
/usr/local/go/src/pkg/appengine/user（来自$GOROOT）
/Users/home/src/go/foodbox/src/appengine/user（来自$GOPATH）
如果我使用appengine的go，我会得到以下错误：
load cmd/cgo: package cmd/cgo: 在/Users/home/Application/google_appengine/goroot/src/cmd/cgo中没有Go源文件
似乎默认安装无法找到appengine包（我猜这并不奇怪）。当我使用appengine的go工具时，我不确定问题是什么。有人可以告诉我如何解决这个问题吗？
谢谢！

I have my appengine SDK in ~/Applications/google_appengine
In Eclipse, i've got an external tool setup to run the dev server. It's pointed at:
~/Application/google_appengine/dev_appserver.py
Also in Eclipse (Go Preferences), I've set the GOROOT to point to
~/Application/google_appengine/goroot
Now, I'm trying to run some unit tests for my project. If I use my regular go installation (not the appengine one), I get this error:
../../context/context.go:4:2: cannot find package "appengine" in any of:
/usr/local/go/src/pkg/appengine (from $GOROOT)
/Users/home/src/go/foodbox/src/appengine (from $GOPATH)
../../context/data.go:4:2: cannot find package "appengine/datastore" in any of:
/usr/local/go/src/pkg/appengine/datastore (from $GOROOT)
/Users/home/src/go/foodbox/src/appengine/datastore (from $GOPATH)
../../context/context.go:5:2: cannot find package "appengine/user" in any of:
/usr/local/go/src/pkg/appengine/user (from $GOROOT)
/Users/home/src/go/foodbox/src/appengine/user (from $GOPATH)
If i use the appengine go, I get this one:
load cmd/cgo: package cmd/cgo: no Go source files in /Users/home/Application/google_appengine/goroot/src/cmd/cgo
It seems like the default installation can't find the appengine packages (I guess that's not surprising). I'm not sure what the problem is when I use the appengine go tools. Can anyone tell me how to get this to work?
Thanks!

可能值得一提的是，appengine/aetest包现在已经包含在SDK中，自1.8.6版本起。请参阅文档。
基本上，您可以在测试中使用appengine.Context，类似于icub3d/appenginetesting。
引用文档中的示例：
import (
"testing"
"appengine/aetest"
)
func TestMyFunction(t *testing.T) {
c, err := aetest.NewContext(nil)
if err != nil {
t.Fatal(err)
}
defer c.Close()
// 使用c运行需要appengine.Context的代码和测试。
}
英文:
It may be worth mentioning that the appengine/aetest package is now included in the SDK, since 1.8.6. See the documentation.
Basically you get an appengine.Context that can be used in your tests, similar to icub3d/appenginetesting.
Quoting the example from the docs:
import (
"testing"
"appengine/aetest"
)
func TestMyFunction(t *testing.T) {
c, err := aetest.NewContext(nil)
if err != nil {
t.Fatal(err)
}
defer c.Close()
// Run code and tests requiring the appengine.Context using c.
}

查看文档：
http://blog.golang.org/appengine-dec2013
查看名为“本地单元测试”的部分
我认为你要找的是随 SDK 一起提供的 goapp test。
英文:
See the docs:
http://blog.golang.org/appengine-dec2013
Check out the section called "Local Unit Testing"
I think what you are looking for is goapp test that comes with the sdk.
