运行单元测试时出现主键违规 user_id 错误

我的togglefavourite功能如下

func ToggleTrackToFavourite(c *gin.Context) {
    userID := GetCurrentUserID(c)
    trackID, err := strconv.Atoi(c.Param("id"))
    if err != nil {
        c.JSON(http.StatusBadRequest, gin.H{"error": "Invalid Track ID"})
        return
    }
    if err := favourites.CreateTable(db.DB); err != nil {
        c.JSON(http.StatusInternalServerError, gin.H{"error": "Failed to create table" + err.Error()})
        return
    }
    if isInFavorites(userID, trackID) {
        err = favourites.RemoveFavorite(db.DB, userID, trackID)
        if err != nil {
            c.JSON(http.StatusInternalServerError, gin.H{"error": "Failed to remove track from favorites"})
            return
        }

        c.JSON(http.StatusOK, gin.H{"message": "Track removed from favorites"})
    } else {
        err = favourites.InsertFavorite(db.DB, userID, trackID)
        if err != nil {
            c.JSON(http.StatusInternalServerError, gin.H{"error": "Failed to add track to favorites : " + err.Error()})
            return
        }

        c.JSON(http.StatusOK, gin.H{"message": "Track added to favorites"})
    }
}

func GetCurrentUserID(c *gin.Context) int {
    userID, exists := c.Get("userID")
    if !exists {
        return 0
    }
    if userIDInt, ok := userID.(int); ok {
        return userIDInt
    }
    return 0
}

上述代码的单元测试函数如下

func TestToggleTrackToFavourite(t *testing.T) {
    db.InitTestDB()

    if err := users.CreateTable(db.DB); err != nil {
        t.Fatalf("Failed to create users table: %v", err)
    }
    if err := tracks.CreateTable(db.DB); err != nil {
        t.Fatalf("Failed to create tracks table: %v", err)
    }
    if err := favourites.CreateTable(db.DB); err != nil {
        t.Fatalf("Failed to create favorites table: %v", err)
    }
    user := users.User{
        Username: "Test",
        Email:    "[email protected]",
        Password: "123456",
    }
    if err := users.CreateUser(db.DB, &user); err != nil {
        t.Fatalf("Failed to create user: %v", err)
    }

    sampleTrack := tracks.Track{
        Name:         "Test track",
        Index:        10,
        Track:        "chere.mp4",
        Image:        "image.jpg",
        Album_ID:     4,
        Is_Published: true,
    }
    if err := tracks.CreateTrack(db.DB, &sampleTrack); err != nil {
        t.Fatalf("Failed to insert the example track: %v", err)
    }

    r := gin.Default()
    r.PUT("/user/favorite/toggle/:id", ToggleTrackToFavourite)

    reqAddToFavorites := httptest.NewRequest("PUT", "/user/favorite/toggle/1", nil)
    wAddToFavorites := httptest.NewRecorder()

    r.ServeHTTP(wAddToFavorites, reqAddToFavorites)
    assert.Equal(t, http.StatusOK, wAddToFavorites.Code)
    assert.Equal(t, `{"message":"Track added to favorites"}`, wAddToFavorites.Body.String())

    // reqRemoveFromFavorites := httptest.NewRequest("PUT", "/user/favorite/toggle/1", nil)
    // reqAddToFavorites.Params = append(reqAddToFavorites.Params, httptest.Param{"id", "1"})
    // wRemoveFromFavorites := httptest.NewRecorder()
    // r.ServeHTTP(wRemoveFromFavorites, reqRemoveFromFavorites)
    // assert.Equal(t, http.StatusOK, wRemoveFromFavorites.Code)
    // assert.Equal(t, `{"message":"Track removed from favorites"}`, wRemoveFromFavorites.Body.String())

    if _, err := db.DB.Exec("DROP TABLE IF EXISTS favorite"); err != nil {
        t.Fatalf("Failed to drop the table: %v", err)
    }
    if _, err := db.DB.Exec("DROP TABLE IF EXISTS tracks"); err != nil {
        t.Fatalf("Failed to drop the table: %v", err)
    }
    if _, err := db.DB.Exec("DROP TABLE IF EXISTS users"); err != nil {
        t.Fatalf("Failed to drop the table: %v", err)
    }
}

不知道如何在单元测试中将 GETCURRENTUSER 函数的默认值传递为 1

只想从收藏夹中添加/删除曲目

正确答案

代码中的用户 ID 似乎存储在处理程序之前的某些身份验证中间件的上下文局部变量中名为“userId”的局部变量中，因此设置它足以进行测试，您可以更改这些行：

r := gin.Default()
    c.Set("userID", "1")
    r.PUT("/user/favorite/toggle/:id", ToggleTrackToFavourite)
