TFS 2017运行功能测试在OutOfMemoryException中运行（未保存结果）

我有一个大约280个测试的测试运行。在这237个测试中，有一个被执行（其余的被跳过）。测试通过运行功能测试执行，并在一台机器上运行。运行完成后

但TFS从未显示这些结果，因为存在OutOfMemory异常。根据日志，我假设这是在传输测试结果时发生的

DTAExecutionHost.exe Error: 0 : ExecutionTaskStateModel.ExecuteTask: Recived error while executing task: System.AggregateException: One or more errors occurred. ---> System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.

构建日志中的详细信息错误是什么？您是否在构建定义中使用发布测试结果任务？我添加了一些日志，您指的是这些日志吗？我使用分布式测试运行。这一个发布测试结果本身。很抱歉，缺少注释。你的问题解决了吗？什么是分布式测试运行？在生成定义中使用哪个测试任务？您使用的是Visual Studio测试任务还是运行功能测试任务？能否将280个测试分为多个测试运行，以查看问题是否仍然存在。我还打开了一个github。但是还没有得到任何反馈。在那里我发布了我尝试过的不同的东西。我已将测试拆分为6个，并将VM重置为干净的快照。这很有效。但是大约需要半个小时。用户运行功能测试任务。生成日志中的详细错误是什么？您是否在构建定义中使用发布测试结果任务？我添加了一些日志，您指的是这些日志吗？我使用分布式测试运行。这一个发布测试结果本身。很抱歉，缺少注释。你的问题解决了吗？什么是分布式测试运行？在生成定义中使用哪个测试任务？您使用的是Visual Studio测试任务还是运行功能测试任务？能否将280个测试分为多个测试运行，以查看问题是否仍然存在。我还打开了一个github。但是还没有得到任何反馈。在那里我发布了我尝试过的不同的东西。我已将测试拆分为6个，并将VM重置为干净的快照。这很有效。但是大约需要半个小时。我运行用户功能测试任务。
