单元测试在发布配置中失败，但在调试模式下通过

Question

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();
}

上述测试失败，在释放模式下出现以下错误：

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

当我在调试模式下运行它时，这个完全相同的测试通过了。

正如Ken Y-N所建议的，在设置中对浮点数进行四舍五入有助于在调试和发布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)));
