Spock中的运行时异常模拟groovy.sql [英] Runtime Exception Mocking groovy.sql in Spock

问题描述

为了寻找能够在Spock规范中运行此代码的正确配置/语法，我一直在StackOverflow和Google周围搜寻:

I've scoured around StackOverflow and Google for a while trying to find the right configuration/syntax for being able to run this code in a Spock Specification:

Sql mockSql = Mock()

但是，当我运行单元测试时，CGLIB抛出了一个令人讨厌的异常:

However when I run the unit test, I get a nasty exception thrown in my face by CGLIB:

java.lang.IllegalAccessError: tried to access method groovy.sql.Sql.<init>()V from class groovy.sql.Sql$$EnhancerByCGLIB$$d0b7cd7f
at org.spockframework.mock.runtime.MockInstantiator.instantiate(MockInstantiator.java:33)

我查看了这个问题/答案-使用GroovyMock或类似方法模拟静态方法在Spock中-希望它可以为我提供一个很好的起点，但是对于我而言，该类是在groovy.Sql中被嘲笑的，所以它是一个groovy类，因此我不确定它是否是正确的起点.

I looked at this question/answer - Mock static method with GroovyMock or similar in Spock - hoping it might give me a good starting point, but the class being mocked in my case, groovy.Sql IS a groovy class, so I'm not sure it's the right place to start.

我已经使用GroovyMock在其他单元测试中成功测试了Groovy.Sql，但是我希望也许我只是错过了可以做到的东西，这样我才能让Spock magic和Groovy SQL一起开心.如果我只是在某个地方错过了答案，我深表歉意-希望我不会重复别人的询问.

I've successfully tested Groovy.Sql in other unit tests using GroovyMock, but I was hoping maybe I just missed something that can make it so that I can have Spock magic and Groovy SQL all happy together. My apologies if I just missed the answer somewhere - hopefully I'm not repeating someone else's inquiry.

推荐答案

使用Spock模拟类(而不是接口)时，建议将objenesis-1.2或更高版本放在测试运行时类路径上(除CGLIB之外).否则，Spock将无法避免执行要模拟的类的构造函数，这可能会带来不良后果.

When mocking classes (rather than interfaces) with Spock, putting objenesis-1.2 or higher on the test runtime class path is recommended (in addition to CGLIB) . Otherwise, Spock won't be able to avoid executing the constructor of the class to be mocked, which may have undesired side effects.
