以上的解决方案在我的案例中并不适用。我不能使用ArgumentCaptor方法被调用了几次，我需要验证每一个。一个简单的使用“argThat”的Matcher很容易做到这一点。

定制的匹配器

// custom matcher
private class PolygonMatcher extends ArgumentMatcher<PolygonOptions> {
    private int fillColor;
    public PolygonMatcher(int fillColor) {
        this.fillColor = fillColor;
    }

    @Override
    public boolean matches(Object argument) {
        if (!(argument instanceof PolygonOptions)) return false;
        PolygonOptions arg = (PolygonOptions)argument;
        return Color.red(arg.getFillColor()) == Color.red(fillColor)
                && Color.green(arg.getFillColor()) == Color.green(fillColor)
                && Color.blue(arg.getFillColor()) == Color.blue(fillColor);
    }
}

测试运行器

// do setup work setup
// 3 light green polygons
int green = getContext().getResources().getColor(R.color.dmb_rx_bucket1);
verify(map, times(3)).addPolygon(argThat(new PolygonMatcher(green)));

// 1 medium yellow polygons
int yellow = getContext().getResources().getColor(R.color.dmb_rx_bucket4);
    verify(map, times(1)).addPolygon(argThat(new PolygonMatcher(yellow)));

// 3 red polygons
int orange = getContext().getResources().getColor(R.color.dmb_rx_bucket5);
verify(map, times(3)).addPolygon(argThat(new PolygonMatcher(orange)));

// 2 red polygons
int red = getContext().getResources().getColor(R.color.dmb_rx_bucket7);
verify(map, times(2)).addPolygon(argThat(new PolygonMatcher(red)));

refEq的javadoc提到了相等性检查是浅的!你可以在下面的链接找到更多的细节:

https://static.javadoc.io/org.mockito/mockito-core/2.2.29/org/mockito/ArgumentMatchers.html refEq (T) % 20以…)

当你使用其他没有实现.equals()方法的类时，“浅相等”问题无法控制，“DefaultMongoTypeMapper”类就是一个没有实现.equals()方法的例子。

support提供了一种方法，可以生成bean定义，而不是创建对象的实例，并且可以使用它来摆脱比较失败。

 genericBeanDefinition(DefaultMongoTypeMapper.class)
                        .setScope(SCOPE_SINGLETON)
                        .setAutowireMode(AUTOWIRE_CONSTRUCTOR)
                        .setLazyInit(false)
                        .addConstructorArgValue(null)
                        .getBeanDefinition()

**“bean定义只是对bean的描述，而不是bean本身。 bean描述正确地实现了equals()和hashCode()，所以我们提供了一个定义，告诉spring应该如何创建一个DefaultMongoTypeMapper()，而不是创建一个新的DefaultMongoTypeMapper。”

在你的例子中，你可以这样做

Mockito.verify(mockedObject)
       .doSoething(genericBeanDefinition(YourClass.class).setA("a")
       .getBeanDefinition());

如果使用Java 8，可以使用Lambda表达式进行匹配。

import java.util.Optional;
import java.util.function.Predicate;

import org.hamcrest.BaseMatcher;
import org.hamcrest.Description;

public class LambdaMatcher<T> extends BaseMatcher<T>
{
    private final Predicate<T> matcher;
    private final Optional<String> description;

    public LambdaMatcher(Predicate<T> matcher)
    {
        this(matcher, null);
    }

    public LambdaMatcher(Predicate<T> matcher, String description)
    {
        this.matcher = matcher;
        this.description = Optional.ofNullable(description);
    }

    @SuppressWarnings("unchecked")
    @Override
    public boolean matches(Object argument)
    {
        return matcher.test((T) argument);
    }

    @Override
    public void describeTo(Description description)
    {
        this.description.ifPresent(description::appendText);
    }
}

示例调用

@Test
public void canFindEmployee()
{
    Employee employee = new Employee("John");
    company.addEmployee(employee);

    verify(mockedDal).registerEmployee(argThat(new LambdaMatcher<>(e -> e.getName()
                                                                         .equals(employee.getName()))));
}

另一个简单的方法是:

import org.mockito.BDDMockito;    
import static org.mockito.Matchers.argThat;
import org.mockito.ArgumentMatcher;

BDDMockito.verify(mockedObject)
        .someMethodOnMockedObject(argThat(new ArgumentMatcher<TypeOfMethodArg>() {

            @Override
            public boolean matches(Object argument) {
                final TypeOfMethodArg castedArg = (TypeOfMethodArg) argument;

                // Make your verifications and return a boolean to say if it matches or not
                boolean isArgMarching = true;

                return isArgMarching;
            }
        }));
