如何编写不等于某物的匹配器

2022-01-14 00:00:00 mockito java junit matcher

我正在尝试为通话创建模拟.假设我有这个方法，我正在尝试存根:

I am trying to create a mock for a call. Say I have this method I am trying to stub out:

class ClassA {
  public String getString(String a) {
    return a + "hey";
  }
}

我想模拟的是:第一个实例是

What I am trying to mock out is: 1st instance is

when(classA.getString(eq("a")).thenReturn(...);`

在同一个测试用例中

when(classA.getString([anything that is not a])).thenReturn(somethingelse);

第二种情况是我的问题:我如何匹配 anyString() 而不是 "a"?

The 2nd case is my question: How do I match anyString() other than "a"?

推荐答案

有了 Mockito 框架，你可以使用 AdditionalMatchers

With Mockito framework, you can use AdditionalMatchers

ClassA classA = Mockito.mock(ClassA.class);
Mockito.when(classA.getString(Matchers.eq("a"))).thenReturn("something"); 
Mockito.when(classA.getString(AdditionalMatchers.not(Matchers.eq("a")))).thenReturn("something else");

希望对你有帮助.
