java - 如何模拟/ stub jOOQ UpdatableRecordImpl store() 方法？

Question

我已经设法 stub update():

@Test
public void updateStubbed() {
    UpdatableRecordTest updatableRecordTest = spy(new UpdatableRecordTest());
    doReturn(1).when(updatableRecordTest).update();
}

但是，当我尝试 stub store() 时:

@Test
public void storeStubbed() {
    UpdatableRecordTest updatableRecordTest = spy(new UpdatableRecordTest());
    doReturn(1).when(updatableRecordTest).store();
}

我得到错误:

org.mockito.exceptions.misusing.WrongTypeOfReturnValue:
Integer cannot be returned by fieldsRow() fieldsRow() should return Row

If you're unsure why you're getting above error read on. Due to the nature of the syntax above problem might occur because:

1. This exception might occur in wrongly written multi-threaded tests. Please refer to Mockito FAQ on limitations of concurrency testing.
2. A spy is stubbed using when(spy.foo()).then() syntax. It is safer to stub spies -
   • with doReturn|Throw() family of methods. More in javadocs for Mockito.spy() method.

如何 stub store()方法？

Answer 1

您不能使用 Mockito 模拟 store() 方法，因为它是一个 final 方法，并且 Mockito 不支持模拟 final 方法。您可以做的是:

• 对于单元测试，使用 PowerMock(它提供了一种模拟 final 方法的方法，但对 Spring 不友好。只是提一下，以防你使用 Spring)，
• 对于功能测试，创建嵌入式数据库架构，并配置您的 JOOQ 以在测试环境中使用它。

很遗憾，我没有更好的答案。
