如何在類屬性的模擬單元測試中設置默認值？

Question

public MyClass 
{
    bool myflag ;
    bool detail ;
}

private async Task DemoAsync()
{
    MyClass myclassobj = new();
}
//But in test case I want to set default value for `myflag` and `detail` as `true` using mock I'm trying like below but getting error.

[TestMethod()]
public async Task Demotest()
{        
    bool someProperty = true;
    var mock = new Mock<MyClass>();
    mock.SetupSet(m => m.myflag = It.IsAny<bool>())
        .Callback<bool>(p => someProperty = p)
        .Verifiable();   
}

-> 錯誤 - 不支持的表達式：m => m... 上面顯示的最后一個成員之后的下一個成員是非虛擬的、密封的或對代理工廠不可見。

您應該將myflag和detail屬性設為虛擬。 這允許覆蓋值。

public class MyClass 
{
    public virtual bool myflag { get; set; }
    public virtual bool detail { get; set; }
}
