c# - "Cannot verify on real object - use a fake object instead"异常

Question

我使用的是 Typemock Isolator 8.6.2.0 版。 我有以下类(class):

public class A
{
    public B b { get; }

    public A()
    {
        b = new B();
    }
}

public class B
{
    public B()
    {
        Console.WriteLine("In B c'tor");
    }
    public void doSomething()
    {

    }
}

测试方法是:

public void test()
{
    Isolate.Fake.NextInstance<B>();
    A a = new A();
    var bObject = a.b;
    bObject.doSomething();
    Isolate.Verify.WasCalledWithAnyArguments(() => bObject.doSomething());
}

当我运行测试时，出现以下异常:“无法在真实对象上验证 - 请改用伪造对象”，但对象是伪造的! 有谁知道它为什么会发生以及我该如何解决？

像这样写你的测试: `

   public void test()
   {
       var fake = Isolate.Fake.NextInstance<B>();
       A a = new A();
       var bObject = a.b;
       bObject.doSomething();
       Isolate.Verify.WasCalledWithAnyArguments(() => fake.doSomething());

   }
