Question

我在Grails 3中使用Spock进行测试。一个特定的测试用例正在破坏，因为Grails在这种情况下在两个不同的会话中与我的数据库对话。我的规范用@Rollback注释，以回滚每次测试所做的所有更改。

有没有办法为这一个方法禁用@Rollback，然后在测试完成后手动回滚更改？

更新

我的测试规范的精简示例如下：

@Log4j
@Integration
@Rollback
class PublicationReportBreakingSpec extends Specification {

    @Unroll
    @Rollback
    void "Invalidate #type object and check not in report"(type, status, hits, expect)
    {
        //We want to roll back the changes made to the publication after each pass.

        given: "Find a valid #type publication"
        //Finding publication which is Read (valid, should appear in report)
        final Publication pub = getSinglePub(type, status, hits)

        //Set publication to be Unread (invalid, shouldn't appear in report)
        when: "The #type publication is altered to fail"
        pub.setStatus('Unread')
        pub.save(flush:true, failOnError: true)

        then: "Check the properties match the test case"
        pub.status = 'Unread'

        //Generate report of read publications
        when: "The report is run"
        def resp = PublicationController.reportReadPublications()

        //Make sure report doesn't contain the publication
        then: "Check for expected result #expect"
        checkReportExpectedResult(resp, expect)

        where:
        clause                                            | type       | status   | hits || expect
        "Book is unread"                                  | 'Book'     | 'Read'   | 1200 || 0
        "Article is unread"                               | 'Article'  | 'Read'   | 200  || 0
    }

    //Checks report for expect value
    public void checkReportExpectedResult(resp, expect){...} 

    //Returns single publication based on passed in parameters
    public Publication getSinglePub(type, status){...}
}

错误的堆栈跟踪是：

Answer 1

根据Javadoc使用@Rollback(false)注释测试应该可以解决问题。

Answer 2

如果if answer == 'y'无效，可能会出现问题......

作为一种解决方法，注释也可以放在方法级别。因此，从测试类中删除注释并将其放在测试方法上，除了您不想回滚的注释。然后在该规范中添加@Rollback(false)部分以清理您创建的数据。

Answer 3

如果您对回滚更改不感兴趣，则不想使用交易...因此您可以跳过THAT方法中的交易。您可以使用@NotTransactional。

执行此操作

如何在特定方法中阻止@Rollback？
