Beego - 端点测试 [英] Beego - Endpoint Testing

问题描述

我正在为beego测试http定制端点

  package test 
 
 import（
github.com/astaxie/beego
github.com/smartystreets/goconvey/convey
 _golife-api-cons / routers
net / http
net / http / httptest
path / filepath
runtime
testing
）
 
 func init {
 _，file，_，_：= runtime.Caller（1）
 apppath，_：= filepath.Abs​​（filepath.Dir（filepath.Join（file，..+ string（ filepath.Separator））））
 beego.TestBeegoInit（apppath）
} 
 
 // TestGet是运行端点测试的示例
 func TestGet（t * testing.T）{
r，_：= http.NewRequest（GET，/ my / endpoint / fetches / data，nil）
w：= httptest.NewRecorder（）
 beego .BeeApp.Handlers.ServeHTTP（w，r）
 
 beego.Trace（testing，TestGet，Code [％d] \\\
％s，w.Code，w。 Body.String（））
 
 Convey（Subject：Test Station Endpoint \\\
，t，func（）{
 Convey（状态代码应该是200，func（）{
 So（w.Code，ShouldEqual，200）
}）
 Convey（结果不应该为空，func （）{
 So（w.Body.Len（），ShouldBeGreaterThan，0）
}）
}）
} 
  

当我运行去测试-v ，

$ b $我得到了响应 dial tcp：0：getsockopt：connection refused

我正在使用MariaDB运行在我的本地
我已经验证使用 netstat -tulpn ，我的数据库运行得很好（如果我使用邮递员并且服务器正在运行，我会得到一个有效的响应）

包含行 _golife-api-cons / routers后，我得到了一个奇怪的观察结果错误甚至在测试运行之前运行

我的测试通过响应200 OK，但没有任何数据，因为我得到的响应上述错误

编辑

由使用的默认路径TestBeegoInit 使用的函数是 / path / to / my / project / test
其中是不是所需的路径，所以我试着给绝对路径，我仍然无法连接数据库。

很多尝试我都知道，beego在 beego / conf.go 中初始化它的名为 AppPath 的变量，比如 -

  AppPath，_ = filepath.Abs​​（filepath.Dir（os.Args [0]））
  

当你运行你的测试时，你用去测试-v

但结果是 os.Args [0] 是文本可执行文件，它将是 / tmp / path / to / test 而不是 path / to / app / exe

因此，它找不到 config / app.conf ，它位于具有db连接详细信息的应用程序路径中。
beego / conf.go 中的负责行 -
$ b

  appConfigPath = filepath.Join（ AppPath，conf，app.conf）
  

这一切都发生在beego的<$ c $当你说

  import（
github.com/astaxie / beego
 _path / to / routers
）
  

因为这是 -

用init函数创建一个新的包/文件，它看起来有 -

 包通用
 
导入（
os
字符串
）
 
 func init（）{ 
 cwd：= os.Getenv（PWD）
 rootDir：= strings.Split（cwd，tests /）
 os.Args [0] = rootDir [0] //你的路径dir 
} 
  

这里你改变 os。 Args [0] 并指定目录路径

确保在beego之前导入它，所以现在导入将看起来像

 导入（
 _path / to / common
github.com/astaxie/beego
 _path / to / routers
）
  

最后连接到DB！

I am testing http custom endpoint for beego

package test

import (
    "github.com/astaxie/beego"
    . "github.com/smartystreets/goconvey/convey"
    _ "golife-api-cons/routers"
    "net/http"
    "net/http/httptest"
    "path/filepath"
    "runtime"
    "testing"
)

func init() {
    _, file, _, _ := runtime.Caller(1)
    apppath, _ := filepath.Abs(filepath.Dir(filepath.Join(file, ".."+string(filepath.Separator))))
    beego.TestBeegoInit(apppath)
}

// TestGet is a sample to run an endpoint test
func TestGet(t *testing.T) {
    r, _ := http.NewRequest("GET", "/my/endpoint/fetches/data", nil)
    w := httptest.NewRecorder()
    beego.BeeApp.Handlers.ServeHTTP(w, r)

    beego.Trace("testing", "TestGet", "Code[%d]\n%s", w.Code, w.Body.String())

    Convey("Subject: Test Station Endpoint\n", t, func() {
        Convey("Status Code Should Be 200", func() {
            So(w.Code, ShouldEqual, 200)
        })
        Convey("The Result Should Not Be Empty", func() {
            So(w.Body.Len(), ShouldBeGreaterThan, 0)
        })
    })
}

When i run using go test -v ,

I get in response dial tcp :0: getsockopt: connection refused

I am using MariaDB running on my local, I have verified using netstat -tulpn that my database is running perfectly fine (I get a valid response if i use postman and my server is running)

One weird observation , after inclusion of line _ "golife-api-cons/routers" i get this error even before test's are ran

My test passes with response 200 OK , but without any data as i get in response the above mentioned error

EDIT

The default path by used by TestBeegoInit function used is /path/to/my/project/test which is not the desired path , so i tried giving the absolute path too , still i am not able to connect DB.

解决方案

After much trying I came to know that beego initializes its variable called as AppPath in beego/conf.go like -

AppPath, _ = filepath.Abs(filepath.Dir(os.Args[0]))

when you run your tests you run them with go test -v

but as a result the os.Args[0] is the text executable which will be /tmp/path/to/test and not path/to/app/exe

hence as a result it does not find config/app.conf which is in your app path which has db connection details. Responsible line in beego/conf.go -

appConfigPath = filepath.Join(AppPath, "conf", "app.conf")

This all happens in beego's init function when you say

import (
  "github.com/astaxie/beego"
  _ "path/to/routers"
)

Hack for this is -

create a new package / file with init function which looks has -

package common

import (
    "os"
    "strings"
)

func init() {
    cwd := os.Getenv("PWD")
    rootDir := strings.Split(cwd, "tests/")
    os.Args[0] = rootDir[0] // path to you dir
}

here you are changing os.Args[0] and assigning your directory path

make sure you import it before beego so now import will look like

import (
  _ "path/to/common"
  "github.com/astaxie/beego"
  _ "path/to/routers"
)

And finally you connect to DB !
