Grails Spock单元测试需要模拟事务管理器

Question

在Grails 3.1.12中，我想对一个服务进行单元测试:

@Transactional
class PlanService {
    List<Plan> getPlans(Map params) {
        def currentUser = (User)springSecurityService.getCurrentUser()
        return Plan.findAllByCompany(currentUser.employer, params)
    }
}

:

@TestFor(PlanService)
@Mock([Plan, User, Company])
class PlanServiceSpec extends Specification {
    void "Retrieve plan from the current user"() {
        setup:
        // create and save entities here
        when: "the plans are retrieved"
        def params = null
        def plans = service.getPlans(params)
        then: "the result should only include plans associated to the current user's company"
        plans.size() == 2
}

从控制台运行测试:

grails> test-app my.PlanServiceSpec -unit

失败:

my.FundingPlanServiceSpec > Retrieve plan from the current user FAILED
java.lang.IllegalStateException at PlanServiceSpec.groovy:48

和测试报告(HTML):

java.lang.IllegalStateException: No transactionManager was specified.
Using @Transactional or @Rollback requires a valid configured transaction manager.
If you are running in a unit test ensure the test has been properly configured
and that you run the test suite not an individual test method.

现在，如果我注释掉服务中的@Transactional注释，测试通过了，但这不是预期的实现。我可以通过模拟事务管理器来解决这个问题:

service.transactionManager = Mock(PlatformTransactionManager) {
    getTransaction(_) >> Mock(TransactionStatus)
}

但这看起来很尴尬，如果不是错误的话。

是不是有什么咒语我忘记用了?

编辑:看起来和以前的bug很像，但是已经关闭一年多了

Answer 1

你试过什么评论说，解决这个问题吗?如果没有，试着用:

注释测试类

@TestMixin(DomainClassUnitTestMixin)

然后:

service.transactionManager = getTransactionManager()

Answer 2

在grails 3.3.2中测试事务性服务时遇到了同样的错误。

添加DataTest接口为我解决了这个问题。

class HelloServiceSpec extends Specification implements ServiceUnitTest<HelloService>, DataTest { }
