Question

Mockito的新手 - 为什么这会给我一个InvalidUseOfMatchers异常的任何想法？我在调用Mockito.verify（）时对方法的每个参数都使用了匹配器。验证是在一个接口方法上运行的，我已经让它在具有类似签名的相同接口上使用其他方法，所以我认为我必须遗漏一些明显的东西。

对于后台，这里有几个参与测试的精简应用程序类：

public class QueueEntry {
   private String _id;

   public QueueEntry(String theId) {
       _id = theId;
   }

   public String getId() { return _id; }
}

public interface IHandler {
   public void onError(QueueEntry arg1, String arg2, String arg3);
}

...我正在为IHandler设置一个模拟器，它是被测试类的依赖项，并希望验证＆＃39; onError＆＃39;使用Mockito匹配器使用特定参数调用方法。这是我对QueueEntry参数的自定义匹配器（上面接口定义中的arg1）：

class EntryMatcher extends BaseMatcher<QueueEntry> {
    private QueueEntry _entry = null;
    public EntryMatcher(QueueEntry theEntry) {
        _entry = theEntry;
    }

    @Override
    public void describeTo(Description description) {
        description.appendText("Queue entry id of <" + _entry.getId() + ">");
    }

    @Override
    public boolean matches(Object item) {
        QueueEntry theEntry = (QueueEntry)item;
        return theEntry.getId().equals(_entry.getId());
    }
}

...我正在创建这样的模拟：

IHandler theHandler = Mockito.mock(IHandler.class);

...然后像这样实例化自定义匹配器：

EntryMatcher matchesEntry = new EntryMatcher( anEntryInstance );

......这就是我得到异常的地方

Mockito.verify(theHandler).onError( Mockito.argThat( matchesEntry ),
                                    Mockito.eq( anObject.aMethodReturningAString() ),
                                    Mockito.eq( "Job failed" ) );

...这里是异常追踪：

org.mockito.exceptions.misusing.InvalidUseOfMatchersException:  Invalid use of argument matchers! 0 matchers expected, 1 recorded:
-> at unit.be.publishing.TestCases.testCase(TestCases.java:183)

This exception may occur if matchers are combined with raw values:
    //incorrect:
    someMethod(anyObject(), "raw String"); When using matchers, all arguments have to be provided by matchers. For example:
    //correct:
    someMethod(anyObject(), eq("String by matcher"));

For more info see javadoc for Matchers class.
