如何从 TFS Api 获取测试结果 trx 文件（从 vstest 生成）答案

【问题描述】：

我需要从 TFS 2013 查询并获取测试结果 trx 文件，以便我可以修改该文件并将其用于生成报告。我在 IBuildServer 中找不到任何允许我查询 trx 文件的方法。是否可以使用BuildDetail.DropLocation 读取文件，其中我有告诉我 trx 文件位置的字符串。我写了几行如下

TfsSerice = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri(tfsUri));
TfsSerice.EnsureAuthenticated();
var buildServer = (IBuildServer)TfsSerice.GetService(typeof(IBuildServer));
BuildDetail = buildServer.QueryBuilds("MyUserLibrary").FirstOrDefault();

【解决方案1】：

您可以使用下面的代码来读取.trx测试结果文件：

TfsTeamProjectCollection tfs = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri("http://tfsservername:8080/tfs/DefaultCollection"));
        ITestManagementTeamProject project = tfs.GetService<ITestManagementService>().GetTeamProject("teamprojectname");

        foreach (ITestRun tRun in project.TestRuns.ByBuild(new Uri(("vstfs:///Build/Build/531"))))
        {
            foreach (ITestCaseResult tr in tRun.QueryResults())
            {
                Console.WriteLine(tr.TestCaseTitle.ToString() + ":" + tr.Outcome.ToString());
            }
        }

请注意，您需要选择将 vstfs:///Build/Build/531 替换为您自己的 buildUri。要获取它，请使用以下代码：

IBuildServer buildServer = (IBuildServer)tfs.GetService(typeof(IBuildServer));
        var buildDefinitions = buildServer.QueryBuildDefinitions("TeamProject");


        foreach (var buildDefinition in buildDefinitions)
        {
            if (buildDefinition.Name == "BuildDefinitionName")
            {
                var builds = buildDefinition.QueryBuilds();
                foreach (var build in builds)
                {
                    Console.WriteLine(build.Uri);
                }
            }

Tx 伙计，我写了一个 TFS Service Wrapper，如下所示。

想通了。我添加了一个 TFS 服务包装器，如下所示，它获取最新版本的 TRX 文件。下面是代码，享受！！！！

                var settings = new XmlReaderSettings {XmlResolver = resolver};
                var reader = XmlReader.Create(latestRun.Attachments[0].Uri.ToString(), settings);
                return XDocument.Load(reader);
            }
        }

    }
}
