Grab test's pass/fail from TestCase via TFS Rest API - tfs

Question

I'm trying to grab the Outcome off of a testcase in TFS, looks something like this.
and I can't seem to find a straightforward way to do it. I've tried to grab the workitem directly, query for the property with no success. I was able to use the SDK to get the data (which I'm trying to avoid)
_tfs = new TfsTeamProjectCollection(new Uri(website)) { ClientCredentials = what };
_tfs.EnsureAuthenticated();
var testService = _tfs.GetService<ITestManagementService>();
var aPoint = plan.QueryTestPoints("SELECT * FROM TestPoint WHERE TestCaseId = 10").SingleOrDefault();
console.Write(aPoint.MostRecentResultOutcome);
I have the ID for the testcase from the webhook so that's not a problem. All I want is that "MostRecentResultOutcome". Is there a way to get that data from the REST api in 1 call?

You could also use below REST API which will return a list of test points through test case ID according to your code info:
GET https://Fabrikam-Fiber-inc.VisualStudio.com/DefaultCollection/fabrikam-fiber-tfvc/_apis/test/plans/1/suites/1/points?testcaseid=39&api-version=1.0
Then will get a response with lastTestRun, lastResutl, outcome...
{
"value": [
{
"id": 1,
"url": "https://fabrikam-fiber-inc.visualstudio.com/DefaultCollection/fabrikam-fiber-tfvc/_apis/test/Plans/1/Suites/1/Points/1",
"assignedTo": {
"id": "d291b0c4-a05c-4ea6-8df1-4b41d5f39eff",
"displayName": "Jamal Hartnett"
},
"configuration": {
"id": "2",
"name": "Windows 8"
},
"lastTestRun": {
"id": "28"
},
"lastResult": {
"id": "100000"
},
"outcome": "Passed",
"state": "Completed",
"testCase": {
"id": "39",
"url": null,
"webUrl": null
},
"workItemProperties": [
{
"workItem": {
"key": "Microsoft.VSTS.TCM.AutomationStatus",
"value": "Not Automated"
}
}
]
}
],
"count": 1
}

As Patrick said, you can't as of right now. What I ended up doing its grabbing the ID and System.TeamProject off of the webhook passing that along as such
private TfsTeamProjectCollection _tfs;
private ITestManagementTeamProject _project;
private readonly ITestManagementService _service;
public TfsThing(string instanceUrl, string user, string password)
{
var cred = new VssBasicCredential(user, password);
_tfs = new TfsTeamProjectCollection(new Uri(instanceUrl)) { ClientCredentials = cred };
_tfs.EnsureAuthenticated();
_service = _tfs.GetService<ITestManagementService>();
}
public string GetTestStatus(int id, string projectName)
{
var project = _service.GetTeamProject(projectName);
var result = project.TestResults.ByTestId(id);
return result.LastOrDefault()?.Outcome.ToString();
}
This was the shortest way I found -- may not be the most efficient though
Incase you were wondering, these are the two packages I used
Install-Package Microsoft.TeamFoundationServer.Client
Install-Package Microsoft.TeamFoundationServer.ExtendedClient
