Annotating TDs with test results

Coming from https://github.com/w3c/wot-testing/issues/189

Once a Thing is tested via its TD where multiple requests are sent to the Thing, it would be nice to incorporate this information to TD, similar to the badges that repositories have. The question is how to do that. Below is an initial thought:

{
    "@context": "https://www.w3.org/2019/wot/td/v1",
    "title": "My Thing",
    "id": "urn:dev:ops:32473-WoTLamp-1234",
    "links": [{
        "href": "https://app.codecov.io/wot/urn:dev:ops:32473-WoTLamp-1234",
        "rel": "report",
        "testResult": {
            "testSuite": "https://github.com/tum-esi/testbench",
            "totalTests": 120,
            "passedTests": 100
        }
    }]
}

What is definitely needed:

Concrete resource containing the results. href in this case What would be nice to have:
A quick way to see the results. totalTests and passedTests here.
The tool/service that did the tests. testSuite here.
