Question

我用一个域和一个控制器创建了Grails应用程序。在开发环境中，我为domain插入了两个条目。我想执行集成测试，以便它从数据库中获取记录并返回总大小。下面是我尝试过的源代码。

以下是我的域

Student.groovy.

import grails.gorm.transactions.Transactional

@Transactional
class Student {

String name
String rollnumber
    static constraints = {
    }
}

下面是我的控制器：-

import grails.gorm.transactions.Transactional

@Transactional
class StudentController {

 def readall(){
       println "inside read all "+Student.getAll().size()
       respond Student.getAll()
     }
}

下面是我的集成测试代码：

import grails.testing.gorm.DomainUnitTest
import grails.testing.mixin.integration.Integration
import grails.testing.web.controllers.ControllerUnitTest
import grails.validation.ValidationException
import spock.lang.Specification
@Integration
class StudentControllerSpec extends Specification implements ControllerUnitTest<StudentController>, DomainUnitTest<Student> {

void "getAllStudentList"(){
        given:
        def studentList=[]
        when:
        request.method = 'GET'
        controller.readall()
        println studentList.size()
        then:
        studentList.size()==1

    }
}

下面是我的application.yml文件

                jdbcInterceptors: ConnectionState
                defaultTransactionIsolation: 2 # TRANSACTION_READ_COMMITTED

我在运行测试用例时遇到异常

从您的域类中删除@Transactional。 @Transactional用于在服务/控制器上开始事务-但在域类中没有意义。

错误是GORM试图创建transaction_manager的列，因为@Transactional向类添加了transactionManger的属性，并且该类型的休眠没有意义。

如何在不使用服务的情况下在Grails 3.3.6中测试控制器操作
