coverage raw data with empty url is created when the test case include Deno.statSync call

[kt3k]

Save the below file as test.ts:

Deno.test("test", () => {
  Deno.statSync(".");
});

And run the command deno test --coverage -A test.ts, then something like the following 2 json files are created:

{
  "scriptId": "308",
  "url": "file:///path/to/test.ts",
  "functions": [
    {
      "functionName": "",
      "ranges": [{ "startOffset": 0, "endOffset": 50, "count": 1 }],
      "isBlockCoverage": true
    },
    {
      "functionName": "",
      "ranges": [{ "startOffset": 18, "endOffset": 47, "count": 1 }],
      "isBlockCoverage": true
    }
  ]
}

{
  "scriptId": "303",
  "url": "",
  "functions": [
    {
      "functionName": "",
      "ranges": [{ "startOffset": 1, "endOffset": 1679, "count": 1 }],
      "isBlockCoverage": false
    }
  ]
}

The second json file has empty url property and causes deno coverage command failure.

Notes:

• Deno.stat doesn't cause the same issue.
• The same issue happens when Deno.statSync called at the top level.
• The same issue happens when Deno.statSync is called in dependencies (and therefore this affects the @std/fs test coverage reports, for example)

Version: Deno 1.43.6

This happens because statSync internally use Function constructor and that part is caught as another script (with empty url).

The below causes the same issue:

Deno.test("test", () => {
  eval("console.log(1)");
});
