是否有可能使用Moq在C＃中從另一個模擬中返回一個模擬？

Question

我正在使用Moq作爲我的嘲笑框架。根據下面的代碼，我有兩個模擬設置，我想設置第二個返回第一個模擬。這是可能的，如果是的話，我會怎麼做呢？目前它說模擬被返回是一個無效的候選人。

[SetUp] 
private void SetupMarketRow() 
{ 
    var marketTotalRow = new Mock<ITotalRow>(); 
    marketTotalRow.Setup(r => r.TotalBudgetCurrentFact).Returns(1860716); 
    marketTotalRow.Setup(r => r.TotalBudgetEvol).Returns(-26); 
    marketTotalRow.Setup(r => r.TotalBudgetPreviousFact).Returns(2514079); 


    var localMarketReport = new Mock<IReport>(); 
    localMarketReport.Setup(r => r.TotalRow).Returns(marketTotalRow); 
    // Red swiggley here saying invalid candidate 

} 

Answer 1

您可以使用marketTotalRow.Object訪問實際的Mocked ITotalRow。

[SetUp] 
private void SetupMarketRow() 
{ 
    var marketTotalRow = new Mock<ITotalRow>(); 
    marketTotalRow.Setup(r => r.TotalBudgetCurrentFact).Returns(1860716); 
    marketTotalRow.Setup(r => r.TotalBudgetEvol).Returns(-26); 
    marketTotalRow.Setup(r => r.TotalBudgetPreviousFact).Returns(2514079); 


    var localMarketReport = new Mock<IReport>(); 
    localMarketReport.Setup(r => r.TotalRow).Returns(marketTotalRow.Object); 
    // Red swiggley here saying invalid candidate 

} 

Answer 2

從

MarketTotalRow TotalRow { get; } 

不斷變化的接口聲明...

ITotalRow TotalRow { get; } 

解決了這一問題。
