在TFS API中,如何获取给定测试的完整类名？

Question

我有一个ITestCaseResult对象,我无法弄清楚如何从中提取测试类信息.该对象在TestCaseTitle属性中包含测试方法的名称,但在我们的代码库中有很多重复的标题,我想了解更多信息.

假设我有Foo.Bar类Baz和方法的汇编ThisIsATestMethod,我目前只能访问ThisIsATestMethod标题中的信息,但我想获得Foo.Bar.Baz.ThisIsATestMethod.

如何使用TFS API执行此操作？

这是一些精简代码:

var def = buildServer.CreateBuildDetailSpec(teamProject.Name);
def.MaxBuildsPerDefinition = 1;
def.QueryOrder = BuildQueryOrder.FinishTimeDescending;
def.DefinitionSpec.Name = buildDefinition.Name;
def.Status = BuildStatus.Failed | BuildStatus.PartiallySucceeded | BuildStatus.Succeeded;

var build = buildServer.QueryBuilds(def).Builds.SingleOrDefault();
if (build == null)
    return;

var testRun = tms.GetTeamProject(teamProject.Name).TestRuns.ByBuild(build.Uri).SingleOrDefault();
if (testRun == null)
    return;

foreach (var outcome in new[] { TestOutcome.Error, TestOutcome.Failed, TestOutcome.Inconclusive, TestOutcome.Timeout, TestOutcome.Warning })
    ProcessTestResults(bd, testRun, outcome);

...

private void ProcessTestResults(ADBM.BuildDefinition bd, ITestRun testRun, TestOutcome outcome)
{
    var results = testRun.QueryResultsByOutcome(outcome);
    if (results.Count == 0)
        return;


    var testResults = from r in results // The "r" in here is an ITestCaseResult. r.GetTestCase() is always null.
                      select new ADBM.Test() { Title = r.TestCaseTitle, Outcome = outcome.ToString(), ErrorMessage = r.ErrorMessage };
}

您可以通过从TFS下载TRX文件并手动解析来完成此操作.要下载测试运行的TRX文件,请执行以下操作:

    TfsTeamProjectCollection tpc = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri("http://my-tfs:8080/tfs/DefaultCollection"));
    ITestManagementService tms = tpc.GetService<ITestManagementService>();
    ITestManagementTeamProject tmtp = tms.GetTeamProject("My Project");
    ITestRunHelper testRunHelper = tmtp.TestRuns;
    IEnumerable<ITestRun> testRuns = testRunHelper.ByBuild(new Uri("vstfs:///Build/Build/123456"));
    var failedRuns = testRuns.Where(run => run.QueryResultsByOutcome(TestOutcome.Failed).Any()).ToList();
    failedRuns.First().Attachments[0].DownloadToFile(@"D:\temp\myfile.trx");

然后解析TRX文件(XML),查找<TestMethod>元素,该元素包含"className"属性中的完全限定类名:

<TestMethod codeBase="C:/Builds/My.Test.AssemblyName.DLL" adapterTypeName="Microsoft.VisualStudio.TestTools.TestTypes.Unit.UnitTestAdapter, Microsoft.VisualStudio.QualityTools.Tips.UnitTest.Adapter, Version=11.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" className="My.Test.ClassName, My.Test.AssemblyName, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null" name="Test_Method" />
