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"
}
}
