eslint-plugin-tdd

Provides tdd ("assert"-like to put it simple) set of rules.

Currently is tested against chai.js

Installation

Install ESLint either locally or globally.

$ npm install eslint

If you installed ESLint globally, you have to install Chai plugin globally too. Otherwise, install it locally.

$ npm install eslint-plugin-tdd

The project is still very young (literally months old), and there are seven rules under the hood so far. This does not mean you can not use this project - after all this project is dedicated to testing the quality of test code. Keeping in mind that, it is production ready.

Configuration

Add plugins section and specify eslint-plugin-tdd as a plugin.

{
  "plugins": [
    "tdd"
  ]
}

Finally, enable all of the rules that you would like to use.

{
  "rules": {
    "tdd/assert-enforce-boolean": 1,
  }
}

List of supported rules

• assert-enforce-below-above: Enforces using of assert.isBelow / assert.isAbove instead of explicit '>' / '<' comparisons in assert, assert.isTrue, assert.isFalse
• assert-enforce-boolean: Enforces using of assert.isTrue and assert.isFalse wherever and whenever it is possible.
• assert-enforce-implicit-comparison: Enforces using of assert.equal / assert.strictEqual instead of explicit comparisons in assert
• assert-enforce-least-most: Enforces using of assert.isAtLeast / assert.isAtMost instead of explicit '>=' / '<=' comparisons in assert, assert.isTrue and assert.isFalse
• assert-no-boolean-negation: Enforces using of assert.isTrue and assert.isFalse without boolean negation.
• assert-no-operator: Disallows using of assert.operator
• assert-no-typeof: Disallows using of typeof a == b sort of expressions in favor of specialiazed assert.isString, assert.isNumber etc. assertions
