ESLint rules for Jasmine

Usage

1. Install eslint-plugin-jasmine as a dev-dependency:

   npm install --save-dev eslint-plugin-jasmine
   

2. Enable the plugin by adding it to your .eslintrc:

   plugins:
     - jasmine
   

ESLint itself provides a Jasmine environment for Jasmine's global variables. It's therefore recommended to also enable it in your .eslintrc:

plugins:
  - jasmine
env:
  jasmine: true

By default, no rules are enabled. See the next section for more.

Configuration

This plugin exports a recommended configuration that enforces good practices.

To enable this configuration, use the extends property in your .eslintrc config file:

plugins:
  - jasmine
env:
  jasmine: true
extends: "plugin:jasmine/recommended"

See the ESLint config docs for more information about extending configuration files.

Rules

Rule	Recommended	Options
expect-matcher	1,
expect-single-argument	1,
missing-expect	0, 'expect()', 'expectAsync()'	expectation function names
named-spy	0
new-line-before-expect	1
new-line-between-declarations	1
no-assign-spyon	0
no-describe-variables	0
no-disabled-tests	1

prefer-jasmine-matcher	1

prefer-toHaveBeenCalledWith	1
prefer-toBeUndefined	0	['always', 'never']

For example, using the recommended configuration, the no-focused-tests rule is enabled and will cause ESLint to throw an error (with an exit code of 1) when triggered.

You may customise each rule by adding a value in your .eslintrc rules property:

plugins:
  - jasmine
env:
  jasmine: true
rules:
  jasmine/no-focused-tests: 0
  jasmine/no-suite-dupes:
    - 2
    - branch

See configuring rules for more information.
