单元测试因发布配置失败，但以调试模式通过

问题描述

我的单元测试：

[TestMethod]
public void LogAdjustment()
{
    //arrange
    var mrNumber = 123456;
    var adjustmentAmount = 2.0f;
    var startingWeight = 13.0f;
    var expectedWeight = startingWeight + adjustmentAmount;
    var startingRecord = new MasterRecord
    {
        Number = mrNumber,AcceptableNetWeight = startingWeight,QVolume = startingWeight / 1.031f
    };
    var poolRecord = new PoolRecord { MasterNumber = mrNumber };

    var iStoreMock = new Mock<IStore>();
    iStoreMock.Setup(s => s.GetReceipt(mrNumber)).Returns(startingRecord);
    iStoreMock.Setup(s => s.GetPool(mrNumber)).Returns(poolRecord);
    iStoreMock.Setup(s => s.RecordReceipt(It.Is<MasterRecord>(r => r.AcceptableNetWeight == expectedWeight && r.QVolume == expectedWeight / 1.031f));
    iStoreMock.Setup(s => s.GetReceipt(mrNumber)).Returns(startingRecord);

    var recorder = new ReceiptRecorder(iStoreMock.Object);
    var adjustment = new Adjustment { LotId = _clearacceptableNumber,Adjustment = adjustmentAmount };

    //act
    recorder.LogAdjustment(adjustment);

    //assert
    iStoreMock.VerifyAll();
}

以上测试在发布模式下失败，并出现以下错误：

Moq.MockVerificationException：以下设置不匹配：
IStoreMock s => s.RecordReceipt（It.Is（r => r.AcceptableNetWeight == 15 && r.QVolume == 14.54898））

当我在“调试”模式下运行该测试时，该测试完全通过。

解决方法

根据Ken Y-N的建议，对设置中的浮点数进行四舍五入有助于在Debug和Release模式下通过单元测试。

iStoreMock.Setup(s => s.RecordReceipt(
   It.Is<MasterRecord>(r => r.AcceptableNetWeight == expectedWeight 
       && Math.Round(r.QuarantineVolume,5) == Math.Round((expectedWeight/1.031f),5)));
