Installation

This module is distributed via npm which is bundled with node and should be installed as one of your project's devDependencies:

npm install --save-dev cypress-testing-library

With typescript

Typings are defined under cypress-testing-library/typings, and should be added as follows in tsconfig.json:

{
  "compilerOptions": {
    "types": ["cypress", "../cypress-testing-library/typings"]
  }
}

Usage

cypress-testing-library extends Cypress' cy command.

Add this line to your project's cypress/support/commands.js:

import 'cypress-testing-library/add-commands';

You can now use all of dom-testing-library's getBy, getAllBy, queryBy and queryAllBy commands. See dom-testing-library repo for reference

To show some simple examples (from cypress/integration/commands.spec.js):

cy.getAllByText('Jackie Chan').click()
cy.queryByText('Button Text').should('exist')
cy.queryByText('Non-existing Button Text').should('not.exist')
cy.queryByLabelText('Label text', {timeout: 7000}).should('exist')
cy.get('form').within(() => {
  cy.getByText('Button Text').should('exist')
})
cy.get('form').then(subject => {
  cy.getByText('Button Text', {container: subject}).should('exist')
})

cypress-testing-library supports both jQuery elements and DOM nodes. This is necessary because Cypress uses jQuery elements, while dom-testing-library expects DOM nodes. When you pass a jQuery element as container, it will get the first DOM node from the collection and use that as the container parameter for the dom-testing-library functions.
