VSTS：通过Test Run Id检索TestRun（RunType = Automated）

Question

我正在尝试根据Test Run ID（Run Type = Automated）检索TestRun，但它返回null。如果测试运行id为Manual，则返回TestRun对象。是否有任何选项可以根据ID检索自动测试运行？

var tfsCollection = new TfsTeamProjectCollection(new Uri(vstsCollectionUrl), new VssClientCredentials());
tfsCollection.EnsureAuthenticated();

var testMgmtService = tfsCollection.GetService<ITestManagementService>();
var testMgmtTeamProject = testMgmtService.GetTeamProject(vstsProject);

var testRun = testMgmtTeamProject.TestRuns.Find(testRunId);

var testResults = testRun.QueryResultsByStatus(TestResultState.InProgress);
