Question

我有这个方法签名，我想用EasyMock模拟

public BigDecimal getRemainingPremium(BigDecimal baseAmount, Date commencementDate, Date effectiveDate, boolean isComplete)

我的测试代码有

Premium premium = createMock(Premium.class);
// add this line
EasyMock.expect(premium.getCommencementDate()).andReturn(EasyMock.anyObject(Date.class)).anyTimes();
expect(
    premium.getRemainingPremium(
        EasyMock.anyObject(BigDecimal.class),
        EasyMock.anyObject(Date.class),
        EasyMock.anyObject(Date.class),
        EasyMock.anyBoolean()
    ))
    .andReturn(BigDecimal.TEN).anyTimes();

但我一直得到这个匹配器异常。我已经尝试了所有原语组合和EasyMock.anyObject（Boolean.class）＆＃39;。有关解决方法的任何建议吗？

java.lang.IllegalStateException: 4 matchers expected, 5 recorded.
This exception usually occurs when matchers are mixed with raw values when recording a method:
    foo(5, eq(6));  // wrong
You need to use no matcher at all or a matcher for every single param:
    foo(eq(5), eq(6));  // right
    foo(5, 6);  // also right

您正在使用匹配器，您应该使用实际对象。

EasyMock.expect(premium.getCommencementDate()).andReturn(EasyMock.anyObject(Date.class)).anyTimes();

在上面的一行中，您使用了anyObject()匹配器，您真正想要使用Date对象。

我想知道你是否在这个意义上混淆了嘲笑者。 anyObject()匹配器是一种确认使用Date类型的对象调用您模拟的方法的方法。它不会创建可用作Date类的实例的日期对象。为此，您需要创建Date的模拟实例。因此，请记住，匹配器应该用作模拟方法的参数，而不是返回值。

以下预期将解决您的问题：

    Date mockDate = EasyMock.createMock(Date.class);
    final IPremium premium = EasyMock.createMock(IPremium.class);
    EasyMock.expect(premium.getCommencementDate()).andReturn(mockDate).anyTimes();
    expect(
            premium.getRemainingPremium(
                    (BigDecimal) EasyMock.anyObject(),
                    (Date) EasyMock.anyObject(),
                    (Date) EasyMock.anyObject(),
                    EasyMock.anyBoolean()
                    ))
                    .andReturn(BigDecimal.TEN).anyTimes();
    replay(premium);

EasyMock - 匹配器与原始值混合在一起？
