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,

}
expectedArticles = append(expectedArticles, expectedArticle1)
expectedArticle2 := util.Article{

}
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

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

return articles

下面是完整的源代码(分支:运行测试服务)

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
=== RUN TestServiceSuite
=== RUN TestServiceSuite/TestGetArticleService

通过从语言中删除
t *testing.T
解决了该问题。qncylg1j2#
我也有同样的问题
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
