检查接来电（）进行异步方法 [英] Check calls Received() for async method

问题描述

当我运行下面的code：

When I run the following code:

[Test]
public async Task Can_Test_Update()
{
    var response = await _controller.UpdateAsync(Guid.NewGuid());
    response.Valid.Should().BeTrue();

    _commands.Received().UpdateAsync(
        Arg.Is<Something>(
            l => l.Status == Status.Updated)); 
}

如果我增加等待preceding了 _commands.Received（）。UpdateAsync ，它抛出一个空引用异常。我怎样才能阻止这种情况的发生，或者是的await 没有必要？

If I add "await" preceding the "_commands.Received().UpdateAsync", it throws a null reference exception. How can I stop this happening, or is await not necessary?

推荐答案

我这里找到了答案。

I found an answer here.

Received.InOrder(async () =>
{
    await _Commands.Received().UpdateAsync(Arg.Is<Lobby>(l => l.Status == Status.Updated));
});
