Question

我正在尝试测试在echo框架/路由器上构建的golang API。我有以下测试.....

func TestLogout(t *testing.T) {
loadConfig()
db := stubDBs(t)
Convey("When you post to /logout", t, func() {
    Convey("with a valid token, you should get aa success msg and be logged out", func() {
        e := echo.New()
        e.Use(middleware.JWTWithConfig(middleware.JWTConfig{
            SigningKey:  []byte("secret"),
            TokenLookup: "query:user",
        }))
        req, err := http.NewRequest(echo.POST, "auth/logout", strings.NewReader(""))
        if err == nil {
            req.Header.Set(echo.HeaderAuthorization, fmt.Sprintf("Bearer %v", Token))
            rec := httptest.NewRecorder()
            c := e.NewContext(req, rec)
            Logout(db, Models.Redis)(c)
            body := GetJsonBody(rec.Body.String())
            error := body.Path("error").Data()
            msg := body.Path("error").Data().(string)
            pw := body.Path("data.user.password").Data().(string)
            token := body.Path("data.user.token").Data()
            So(error, ShouldEqual, nil)
            So(msg, ShouldEqual, "Logged Out")
            So(rec.Code, ShouldEqual, 200)
            So(pw, ShouldEqual, "")
            So(token, ShouldEqual, nil)
        }

    })
})
}

并在控制器......

//Logout ...
func Logout(db *sqlx.DB, r *redis.Client) echo.HandlerFunc {
    return func(c echo.Context) error {
        var user Models.User
        log.Println(c.Get("user")) //<-----This Logs NIL only on testing
        if c.Get("user") == nil {
            res := createAuthErrorResponse(user, "Invalid Token")
            return c.JSON(http.StatusOK, res)
        }
        token := c.Get("user").(*jwt.Token)
        err := Models.Redis.Del(token.Raw).Err()
        if err != nil {
            handleErr(err)
            res := createAuthErrorResponse(user, "Token not in storage")
            return c.JSON(http.StatusOK, res)
        }
        user.Password = ""
        user.Token = null.StringFrom("")
        res := createAuthSuccessResponse(user, "Logged Out.")
        return c.JSON(http.StatusOK, res)
    }
}

关于如何在cho框架中测试此功能的任何建议？这是我不希望的行为（c.Get（“user”）在测试中的行为与在实时环境中的行为不同）。

通过很多痛苦，我能够弄清楚这一点。这是工作代码。说明如下。

        Convey("with a valid token, you should get a success msg and be logged out", func() {
        e := echo.New()
        req, err := http.NewRequest(echo.POST, "auth/logout", strings.NewReader(""))
        if err == nil {
            req.Header.Set(echo.HeaderAuthorization, fmt.Sprintf("Bearer %v", Token))
            rec := httptest.NewRecorder()
            c := e.NewContext(req, rec)
            middleware.JWTWithConfig(middleware.JWTConfig{
                SigningKey: []byte("secret"),
            })(Logout(db, Models.Redis))(c)
            body := GetJsonBody(rec.Body.String())
            error := body.Path("error").Data()
            msg := body.Path("msg").Data().(string)
            pw := body.Path("data.user.password").Data().(string)
            token := body.Path("data.user.token").Data()
            So(error, ShouldEqual, nil)
            So(msg, ShouldEqual, "Logged Out")
            So(rec.Code, ShouldEqual, 200)
            So(pw, ShouldEqual, "")
            So(token, ShouldEqual, nil)
        }

    })

我已正确设置了Header但未执行JWT echo中间件，这意味着我的令牌未经过验证，并且使用c.Get（）命令可以进行扩展。

这里的关键是测试echo middlware而不运行服务器需要你执行中间件函数，然后它接受一个处理函数（这是你要测试的函数），然后获取上下文。因此，该函数应如下所示来测试您的中间件路由。如果是全部大写，则需要将其替换为特定情况。

A: middleware.MIDDLEWARE_FUNC(NECESSARY_CONFIGS) // <--- this returns echo.MiddlewareFunc

B: (YOUR_HANDLER(req, res)) // <---echo.MiddlewareFunc takes an echo.HanlderFunc as its only argument and you pass your handler you test req, res

(c) // <--Finally, you call the resulting compose function with your test context

A(B())(c)

echo c.Get（“user”）在测试env时不起作用
