使用 Mock 在方法调用中引发作为参数传递的回调

Question

我有一个将回调作为参数的方法：

  public void GetAllAvailableNames(Action<List<string>> callback, Exchange? exchange = null, string symbol = null)
    {
        callback.Invoke(new List<string> {"test"});
    }

如何使用 mock 引发回调，这是我尝试过的方法：

 this._marketDataClientMock
        .Setup(x => x.GetAllAvailableNames( It.IsAny<Action<List<string>>>(), It.IsAny<Exchange>(), It.IsAny<string>()))
        .Callback((List<string> x) => x = this.Vets);

Answer 1

捕获 CallBack 中的操作参数并手动调用它

this._marketDataClientMock
    .Setup(x => x.GetAllAvailableNames( It.IsAny<Action<List<string>>>(), It.IsAny<Exchange>(), It.IsAny<string>()))
    .Callback((Action<List<string>> callback, Exchange? exchange, string symbol) => callback.Invoke(this.Vets));
