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

Question

我用一个域和控制器创建了Grails应用程序。在开发环境中，我已经为域插入了两个条目。我想执行集成测试，以便从数据库中获取记录并返回总大小。下面是我尝试的源代码。

以下是我的域名

Student.groovy.

import grails.gorm.transactions.Transactional

@Transactional
class Student {

String name
String rollnumber
    static constraints = {
    }
}

以下是我的控制器： -

import grails.gorm.transactions.Transactional

@Transactional
class StudentController {

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

以下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

Answer 1

从您的域类中删除@Transactional。 @Transactional用于开始服务/控制器上的事务 - 但它在域类中没有意义。

错误是GORM试图创建一个transaction_manager列，因为@Transactional将transactionManger的属性添加到类中，并且是一种对休眠没有意义的类型。
