Mock constructor with mockito
提问by Mathew Rock
I want to mock a constructor into method.
我想将构造函数模拟为方法。
public String generaID() {
GeneraIDParaEntidadCliente aux = new GeneraIDParaEntidadCliente(nombre, registro);
entidad.setID(aux.generaID);
}
In my test I want do something like this :
在我的测试中，我想做这样的事情：
when(new GeneraIDParaEntidadCliente(anyString(), any(Entidad.class)).thenReturn(generaIdMock)
but give me this errororg.mockito.exceptions.misusing.InvalidUseOfMatchersException:
但给我这个错误org.mockito.exceptions.misusing.InvalidUseOfMatchersException:
Any idea why?
知道为什么吗？

You can use PowerMockto mock constructors.
您可以使用PowerMock来模拟构造函数。
If you can't use PowerMock for some reason, the most workable solution is to inject a factory to whatever class contains this method. You would then use the factory to create your GeneraIDParaEntidadClienteobject and mock the factory.
如果由于某种原因不能使用 PowerMock，最可行的解决方案是将工厂注入包含此方法的任何类。然后您将使用工厂来创建您的GeneraIDParaEntidadCliente对象并模拟工厂。

There are a couple of ways of doing this, described in my article on the Mockito wiki
有几种方法可以做到这一点，在我在 Mockito wiki 上的文章中有所描述

you can send mocked objects as paramemters to your class constructor, form example:
您可以将模拟对象作为参数发送到类构造函数，例如：
// define you object
public MainClassObj instanceClass;
// mock input parameter
MYClassObj mockedObj = Mockito.mock(MYClassObj.class);
// call construvtor with mocked parameter
instanceClass = new instanceClass(mockedObj);
