Assert.ThrowsExceptionAsync不起作用

使用Assert.ThrowsExceptionAsync的正确方法是什么？

你没打电话ThrowsExceptionAsync.你在打电话ThrowsException.调用的正确方法ThrowsExceptionAsync是await结果.

这应该工作:

public async Task GetPlaylistByIdAsync_NonExistingPlaylist_ThrowsPlaylistNotFoundException()
{
  var playlistId = Guid.NewGuid().ToString();
  var manager = PlaylistTargetsFakeFactory.GetPlaylistTargetFusionManager();
  await Assert.ThrowsExceptionAsync(async () =>
  {
     await manager.GetPlaylistByIdAsync(playlistId);
  });
}

或者,更简单地说:

  await Assert.ThrowsExceptionAsync(() =>
     manager.GetPlaylistByIdAsync(playlistId));
