我正在golang中设置单元测试。
但现在我在运行go test -v时遇到了错误。
我希望解决此错误并使测试成功。

现在我将service_test.go设置为service.go
服务测试.go

package service

// import

type MockDaoInterface struct {
}

func (_m *MockDaoInterface) GetArticleDao() *sql.Rows {
    db, mock, _ := sqlmock.New()
    mockRows := mock.NewRows([]string{"id", "uuid", "title", "content"}).
        AddRow(1, "bea1b24d-0627-4ea0-aa2b-8af4c6c2a41c", "test", "test").
        AddRow(2, "844bc620-7336-41a3-9cb4-552a0024ff1c", "test2", "test2")
    mock.ExpectQuery("select").WillReturnRows(mockRows)
    rows, _ := db.Query("select")
    return rows
}

type ServiceSuite struct {
    suite.Suite
    service *Service
    dao     dao.DaoInterface
}

func (s *ServiceSuite) SetupTest() {
    s.service = NewService(s.dao)
    s.service.dao = &MockDaoInterface{}
}

func (s *ServiceSuite) TestGetArticleService(t *testing.T) {

    articles := s.service.GetArticleService()

    var expectedArticles []util.Article

    expectedArticle1 := util.Article{
        ID:      1,
        UUID:    "bea1b24d-0627-4ea0-aa2b-8af4c6c2a41c",
        TITLE:   "test",
        CONTENT: "test",
    }
    expectedArticles = append(expectedArticles, expectedArticle1)

    expectedArticle2 := util.Article{
        ID:      2,
        UUID:    "844bc620-7336-41a3-9cb4-552a0024ff1c",
        TITLE:   "test2",
        CONTENT: "test2",
    }
    expectedArticles = append(expectedArticles, expectedArticle2)

    assert.Equal(s.T(), expectedArticles, articles)
}

func TestServiceSuite(t *testing.T) {
    suite.Run(t, new(ServiceSuite))
}

service.go

package service

// import 

type Service struct {
    dao dao.DaoInterface
}

func NewService(dao dao.DaoInterface) *Service {
    return &Service{dao: dao}
}

func (s Service) GetArticleService() []util.Article {
    var articles []util.Article

    results := s.dao.GetArticleDao()

    article := util.Article{}
    for results.Next() {
        err := results.Scan(&article.ID, &article.UUID, &article.TITLE, &article.CONTENT)
        if err != nil {
            panic(err.Error())
        } else {
            articles = append(articles, article)
        }
    }
    return articles
}

dao.go

package dao

// import

type Dao struct {
    database *sql.DB
    s3       s3.S3Interface
}

func NewDao(database *sql.DB, s3 s3.S3Interface) *Dao {
    objs := &Dao{database: database, s3: s3}
    return objs
}

type DaoInterface interface {
    GetArticleDao() *sql.Rows
}

下面是完整的源代码(分支:运行测试服务)
https://github.com/jpskgc/article/tree/go-test-service
我期望service_test.go能够成功测试。
但实际是它因错误而失败。
我想解决这个错误并成功测试。

$ go test -v

通过从语言中删除t *testing.T解决了该问题。

func (s *ServiceSuite) TestGetArticleService() {
// some code
}

我也有同样的问题

type AnswerApplicationSvcTestSuite struct {
    mock.Mock
    suite.Suite
    svc                   *answerApplicationService
}

我的问题是犹豫要不要把mock.Mock和suete. suite都放进去
我试着删除模拟。模拟
然后就恢复正常了

此方法不应有任何参数

func (s *ServiceSuite) TestGetArticleService(t *testing.T) {

更改为

func (s *ServiceSuite) TestGetArticleService() {
