eslint-plugin-jest-async

ESLint rules for Jest to detect improper test assertions for asynchronous (Promise-based) actions

Installation

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install eslint-plugin-jest-async:

$ npm install eslint-plugin-jest-async --save-dev

Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-jest-async globally.

Usage

Add jest-async to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
    "plugins": [
        "jest-async"
    ]
}

Then configure the rules you want to use under the rules section.

{
    "rules": {
        "jest-async/expect-return": "error"
    }
}

Supported Rules

• jest-async/expect-return
