NUnit Assert.AreEqual(LeftObject,RigtObject)

Question

以下链接表明这应该有效。

Compare equality between two objects in NUnit

[TestFixture()]
public class ResponseMessageUnitTests
{

    private Mock<IConfiguration> _IConfigurationMoq;
    private Mock<ICardReader> _ICardReaderMoq;
    private ResponseMessage responseMessage; 

    public ResponseMessageUnitTests()
    {
        //Act
        this._IConfigurationMoq = new Mock<IConfiguration>();
        _IConfigurationMoq.Setup(x => x.REPEATDELAYTIME).Returns(0);
        _IConfigurationMoq.Setup(x => x.COLOUR_WHOLE_RESPONSE_AREA).Returns(true);
        this._ICardReaderMoq = new Mock<ICardReader>();
        this.responseMessage = new ResponseMessage(_IConfigurationMoq.Object, _ICardReaderMoq.Object);
    } 

    [Test(Description =
    "Calling ResponseMessage DisplayAdditionalInfo_Empty Method " +
    "with a Background Colour that populates the fields " +
    "AdditionalInfoLine[1-4] and " +
    "AdditionalInfoNo[1-4]")]
    [TestCase(BACKGROUNDCOLOURS.GOOD)]
    public void ResponseMessage_DisplayAdditionalInfo_Empty(string backgroundColour)

    {
        //Arrange
        _IConfigurationMoq.Setup(x => x.COLOUR_WHOLE_RESPONSE_AREA).Returns(true);
        _IConfigurationMoq.Setup(x => x.REPEATDELAYTIME).Returns(0);

        DisplayLine expected = new DisplayLine(_IConfigurationMoq.Object, null, null, backgroundColour);

        //Act
        responseMessage.DisplayAdditionalInfo_Empty(backgroundColour);

        //Assert
        Assert.AreEqual(expected,responseMessage.AdditionalInfoLine1);
        //Assert.AreEqual(expected, responseMessage.AdditionalInfoLine2);
        //Assert.AreEqual(expected, responseMessage.AdditionalInfoLine3);
        //Assert.AreEqual(expected, responseMessage.AdditionalInfoLine4);
        //Assert.AreEqual(expected, responseMessage.AdditionalInfoNo1);
        //Assert.AreEqual(expected, responseMessage.AdditionalInfoNo2);
        //Assert.AreEqual(expected, responseMessage.AdditionalInfoNo3);
        //Assert.AreEqual(expected, responseMessage.AdditionalInfoNo4);
    }

如果我在带有 Assert.AreEqual 的行上放置一个断点，我会得到以下结果：

测试失败令我惊讶的是，出现以下错误消息：

Message:   Expected: <EPIC.APIS.REST.Models.Android.DisplayLine>
           But was:  <EPIC.APIS.REST.Models.Android.DisplayLine>

我不明白为什么...这 2 个对象属于同一类型并且包含相同的值？

 <package id="NUnit" version="3.12.0" targetFramework="net462" />

Answer 1

以及您链接到的线程建议，Assert.AreEqual 比较作为参考相等，除非您覆盖它。

所以即使一切看起来都一样，它们也可能是不同的对象/引用。

您可以查看此答案中的 PropertyValuesAreEquals：并像那样比较您的对象，或者覆盖对象的比较
