Class中的Playback.Initialize在测试代理机器上从测试控制器运行时，Initialize会抛出异常 [英] Playback.Initialize in Class Initialize throws exception when run on Test agent machine from test controller
问题描述
我需要在Class Initialize方法中做一些与UI相关的事情。我看到播放没有初始化，并在我的类初始化程序中调用Plaback.Initialize（）。当我在本地运行测试时，这工作正常。但是，当我使用Visual
studio的测试控制器在安装了测试代理的另一台机器上远程运行测试时，我收到以下错误。
< ErrorInfo> < Message>类初始化方法Tests.Scenario1.Initialize引发异常。 Microsoft.VisualStudio.TestTools.UITest.Extension.PlaybackFailureException：Microsoft.VisualStudio.TestTools.UITest.Extension.PlaybackFailureException：

当我在注释掉UI相关代码时，测试代理在本地和远程测试都运行良好类初始化程序。但我需要在Class Initializer中做与UI相关的事情，因为它非常重要。有人可以帮忙吗？

这对我有用。可能会有轻微的性能损失。但是，阻止我把剩下的头发拉出来。我注意到，当我中止测试运行并导致Playback初始化被搞砸时，就会发生这种情况。

I need to do some UI related stuff in Class Initialize method. I see that Playback is not initialized and call Plaback.Initialize() in my Class Initializer. This works fine when I run the tests locally. However, when I use the test controller with Visual studio to run the tests remotely on another machine which has Test Agent installed I get the following error.
<ErrorInfo> <Message>Class Initialization method Tests.Scenario1.Initialize threw exception.

The tests run fine both locally and remotely on the test agent when i comment out the UI related code in Class Initializer. But I need to do that UI related stuff in Class Initializer as it is really important. Can someone help?
Madhu
This worked for me. Might have a slight performance penalty. But, stopped me from pulling the rest of my hair out. I noticed that it happens when i abort a test run and causing the Playback initialization to get screwed up.
[AssemblyInitializeAttribute()]
public static void AssembyInitialize(TestContext TestContext)
{
if (Playback.IsInitialized)
{
Playback.Cleanup();
Playback.Initialize();
}}
[AssemblyCleanupAttribute()]
public static void AssembyCleanup()
{
if (Playback.IsInitialized)
{
Playback.Cleanup();
}}
这篇关于Class中的Playback.Initialize在测试代理机器上从测试控制器运行时，Initialize会抛出异常的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
