Not generating remapped with jest ^18.1.0

I just updated my project to jest@^18.1.0 and ts-jest@^18.0.0, and suddenly my coverage isn’t creating a remapped directory. This was working fine with jest@^17.0.3 and ts-jest@^17.0.0. The only change has been version updates.

package.json:

"jest": "^18.1.0",
"ts-jest": "^18.0.0",

and my config;

{
  "globals": {
    "__TS_CONFIG__": "./src/client/tsconfig.json"
  },
  "moduleFileExtensions": [
    "ts",
    "tsx",
    "js"
  ],
  "transform": {
    ".(ts|tsx)": "./node_modules/ts-jest/preprocessor.js"
  },
  "testResultsProcessor": "./node_modules/ts-jest/coverageprocessor.js",
  "testRegex": "src/client/.*\\.spec\\.(ts|tsx|js)$",
  "collectCoverage": true,
  "collectCoverageFrom": [
    "src/client/**/*.{js,ts,tsx}",
    "!src/client/index.*",
    "!**/node_modules/**"
  ],
  "coverageReporters": ["text", "html"]
}

don’t think i can minimze my repro any further.

it has 2 files/tests; running npm run test:series (with the jest -i flag) generates the remapped folder, while npm run test does not.

you can also reproduce the issue by having an empty index.ts, and a.test.ts/b.test.ts containing just:

import '.'
it('', () => {})

, though this might be an unrelated pathological case.
