jest-extended adds many additional matchers to Jest's default assertions but knowing when to use these matchers isn't always obvious.
eslint-plugin-jest-extended aims to tell you when you should use a specific matcher available in jest-extended.
With npm:
npm install --save-dev eslint-plugin-jest-extendedWith yarn:
yarn add -D eslint-plugin-jest-extendedAdd jest-extended to the plugins section of your .eslintrc configuration file.
{
"plugins": ["jest-extended"]
}See ESLint plugin documentation for more information about using plugins.
Add jest-extended to the extends section of your .eslintrc configuration file to use the recommended setup.
{
"extends": ["plugin:jest-extended/recommended"]
}See ESLint configuration documentation for more information about extending configuration files.
Add rules to your .eslintrc configuration file to either use a rule or override the default configuration if you are
using the recommended setup.
See ESLint rules documentation for more information about adjusting rule settings.
