c# - 检查异步方法的调用 Received()

Question

当我运行以下代码时:

[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)); 
}

如果我在“_commands.Received().UpdateAsync”之前添加“await”，它会抛出空引用异常。我怎样才能阻止这种情况发生，或者 await 不是必需的？

Answer 1

我找到了答案 here .

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