Detects it.only in specs on commit (example)

How to stop committing test files with it.only in BDD tests?

1. Use eslint with whatever rules you want
2. Add eslint-plugin-no-only-tests and maybe set it as a warning by default

{
  "plugins": [
    "no-only-tests"
  ],
  "rules": {
    "no-only-tests/no-only-tests": 1
  }
  }

3. Use husky and lint-staged to grab changed files before commit
4. Enable "no-only-tests" rule in the lint-staged command from command line using eslint --rule to enable the rule. The package.json should define a script name invoked by the linter

"scripts": {
  "test": "eslint src/*.js",
  "precommit-lint": "eslint --fix --rule 'no-only-tests/no-only-tests: 2'",
  "precommit": "lint-staged"
},
"lint-staged": {
  "src/*.js": ["precommit-lint", "git add"],
  "verbose": false
}

Try committing JS file with it.only block and it reports and error

$ git commit -m "try commit"

> husky - npm run -s precommit
> husky - node v6.8.1
