Disallow the use of describe.only() and it.only().

Rationale

When developers fix tests they may make the process easier by filtering tests using method only on it & describe.

However, such filters should not be in the repo when the project is running on CI. So, we add this rule to our ESLint config to check the existence of only in the tests files. And we run linter using precommit-hook, which make it possible to prevent committing when only does exist in the code.

Installation

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install the plugin:

$ npm install @funboxteam/eslint-plugin-no-only-tests --save-dev

Usage

Add @funboxteam/eslint-plugin-no-only-tests to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
  "plugins": [
    "@funboxteam/no-only-tests"
  ]
}

Then configure the rule under the rules section.

{
  "rules": {
    "@funboxteam/no-only-tests/no-only": 2
  }
}
