Test completed json doesn't include location

It would be nice to get the location of the failure. Am I missing something here?

The command I ran was: elm-test "tests\\RoutingTests.elm" --report json

The current return looks like this:

{
  "event": "testCompleted",
  "status": "fail",
  "labels": [
    "RoutingTests",
    "Route.fromUrl",
    "Parsing hash: \"#login\""
  ],
  "failures": [
    {
      "given": null,
      "message": "Expect.equal",
      "reason": {
        "type": "Equality",
        "data": {
          "expected": "Just Login",
          "actual": "Nothing",
          "comparison": "Expect.equal"
        }
      }
    }
  ],
  "duration": "3"
}

Start by running elm-test "tests\\RoutingTests.elm" --report json and inspect the testCompleted report path that produces the shown payload. Trace whether failure locations are available, then verify the JSON includes location data for this failure without breaking its existing fields.
