EasyMock - 匹配器与原始值混合在一起？

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的例外.我已经尝试了所有基元组合和'EasyMock.anyObject(Boolean.class)'.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

Answer 1

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();

在上面的行中,您已经使用了anyObject()匹配器,您真正想要使用Date对象.

我想知道你是否在这种意义上混淆了嘲笑者.anyObject()匹配器是一种确认您使用类型对象调用模拟方法的方法Date.它不会创建可用作Date类实例的日期对象.为此,您需要创建一个模拟实例Date.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.

以下期望将解决您的问题:

    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);
