VS 2019 - Open in browser works, runner does not

[djjohnjoseph]

Can someone point me in the right direction of how to get this working under VS 2019 using the context menu test runner?

I have a .NET Core 3.0 MVC app and am trying to test some javascript compiled from typescript (MSBuild which compiles on save) - Jasmine nuget pacakage 2.6.4.

chutzpah.json (in the project root):

 {
   "Framework": "jasmine",
   "EnableTestFileBatching ": true,
   "RootReferencePathMode ": "SettingsFileDirectory",
   "Compile": {
     "Mode": "External",
     "Extensions": [ ".ts" ],
     "ExtensionsWithNoOutput": [ ".d.ts" ]
   },
   "References": [
     {
       "Path": "scripts/compiled/site.js"
     }
   ],
   "Tests": [
     {
       "Includes": [ "*.spec.js" ],
       "Path": "scripts/tests",
       "ExpandReferenceComments": true
     }
   ]
 }

Project structure:

scripts/
--compiled/
    -- site.js
--tests/
   --app.spec.js
app.ts
ajax.ts

Using the context menu to 'Open in Browser' on the app.spec.js file passes tests. Selecting 'Run JS Tests' however returns an 'Cannot find variable: 'Format'.

app.spec.js:

/// <reference path="../compiled/site.js" />
describe("Format Tests", function () {
    it("Can format a variable in a message", function () {
        var message = "Request failed: {0}";
        var replacement = "Reason";
        var result = "Request failed: Reason";

        expect(Format(message, [replacement])).toBe(result);
    });

    it("Does not replace without placeholder", function () {
        var message = "Request failed:";
        var replacement = "Reason";
        var result = "Request failed:";

        expect(Format(message, [replacement])).toBe(result);
    });
});

compiled/site.js (extract)

function Format(pattern, ...variables) {
    return pattern.replace(/{(\d+)}/g, (match, index) => {
        return typeof variables[index] !== undefined ? variables[index] : match;
    });
}

Stack trace in VS output:

ReferenceError: Can't find variable: Format in file:///C:/Users/test/source/repos/CCBCForms/src/CCBCForms/scripts/tests/app.spec.js (line 8)

I'm stuck as to why the app.spec.js file doesn't seem to be picking up that compiled file that is referenced both using the <reference path> and the References section within the chutzpah config file.

Can anyone shed any light?
