Grails Spock单元测试需要模拟事务管理器 [英] Grails Spock unit test requires to mock transaction manager

问题描述

在Grails 3.1.12中，我要对服务进行单元测试:

In Grails 3.1.12, I want to unit test a service:

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

喜欢这个:

@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

并在测试报告(HTML)中:

and in the test report (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批注，则测试会通过，但这不是预期的实现.我可以通过模拟事务管理器来解决此问题:

Now if I comment out the @Transactional annotation in the service, the test passes, but that's not the intended implementation. I am able to work around the problem by mocking the transaction manager:

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

但这似乎很尴尬，即使没有错.

But this seems very awkward, if not wrong.

我忘了援引一些咒语吗?

Is there some incantation I forgot to invoke?

类似于一个老错误，但是已经关闭了一年多.

looks similar to an old bug, but it's been closed more than a year.

推荐答案

您是否尝试过注释说的解决问题的内容?如果没有，请尝试使用以下方法注释测试类:

Have you tried what a comments says that fixes the problem? If not, try to annotate the test class with:

@TestMixin(DomainClassUnitTestMixin)

然后:

service.transactionManager = getTransactionManager()
