Including all files when not using require or register

[cdibbs]

Expected Behavior

When running a lesser-known testing framework (called Alsatian) with nyc and ts-node, there should be an option to cover all files, despite the absence of a require definition in the config.

Observed Behavior

Coverage seems correct, in terms of individual files, but the results don't include files not directly imported by the tests. My understanding of "all": true that I've gleaned from issues and docs scattered about is that it won't actually include all files without a require. If I try to require ts-node/register with nyc (again, despite it seeming to work, coverage-wise, without that), then all desired files are included, but coverage becomes nonsense, highlighting random byte ranges.

Bonus Points! Code (or Repository) that Reproduces Issue

package.json and runner.ts

  "scripts": {
    "precover": "rimraf ./coverage/*",
    "cover": "nyc npm run unittest",
    "unittest": "ts-node --project tsconfig-xunit.json src/spec-lib/runner.ts"    
  },
  "nyc": {
    "include": [
      "src/lib/**"
    ],
    "extension": [
      ".ts"
    ],
    "exclude": [
      "typings",
      "**/*.d.ts",
      "**/*.test.ts",
      "**/*.spec.ts"
    ],
    "reporter": [
      "json",
      "html"
    ],
    "all": true
  }

I've added a project that demonstrates the bug.

It's also possible this is a ts-node bug, but I am not familiar enough with the inner workings of nyc or ts-node to know for sure.

@cdibbs sorry for the late reply. I'm not sure what you meant by:

there should be an option to cover all files, despite the absence of a require definition in the config.

I was going to suggest trying the newly published https://www.npmjs.com/package/@istanbuljs/nyc-config-typescript but I don't know how you'd get coverage without using a require hook.
