You want to use [DOM Testing Library][dom-testing-library] methods in your
[Cypress][cypress] tests.
This allows you to use all the useful
[DOM Testing Library][dom-testing-library] methods in your tests.

- With TypeScript
- Intellisense for JavaScript with VS Code
- Usage

This module is distributed via [npm][npm] which is bundled with [node][node] and
should be installed as one of your project's devDependencies:
```
npm install --save-dev @testing-library/cypress
Typings should be added as follows in tsconfig.json:
`json`
{
"compilerOptions": {
"types": ["cypress", "@testing-library/cypress"]
}
}
If you're not using TypeScript, you use VS Code, and want to have
code-completion with the methods from this library, simply add the following
line to your project's root-level jsconfig.json file:
`json`
{
"include": ["node_modules/cypress", "./cypress/*/.js"]
}
Cypress Testing Library extends Cypress' cy command.
Add this line to your project's cypress/support/commands.js:
`javascript`
import '@testing-library/cypress/add-commands'
You can now use all of DOM Testing Library's findBy and findAllByDOM Testing Library
commands.
See the docs for reference
You can find
all Library definitions here.
To configure DOM Testing Library, use the following custom command:
`javascript`
cy.configureCypressTestingLibrary(config)
To show some simple examples (from
cypress/e2e/find.cy.js):
`javascript
cy.findAllByText('Button Text').should('exist')
cy.findAllByText('Non-existing Button Text').should('not.exist')
cy.findAllByLabelText('Label text', {timeout: 7000}).should('exist')
cy.findAllByText('Jackie Chan').click()
// findAllByText _inside_ a form element
cy.get('form').findAllByText('Button Text').should('exist')
`
Cypress Testing Library supports both jQuery elements and DOM nodes. This isDOM Testing Library
necessary because Cypress uses jQuery elements, while subject
expects DOM nodes. When you chain a query, it will get the first DOM node from of the collection and use that as the container parameter for theDOM Testing Library functions.
query* queries are not supported. You should use the should('not.exist')
assertion instead to check for the absence of an element.
get queries are not supported. find queries do not use the Promise API ofDOM Testing Library, but instead forward to the get* queries and useget*
Cypress' built-in retryability using error messages from APIs to forward
as error messages if a query fails.
findAll* can select more than one element and is closer in functionality tofind*
how Cypress built-in commands work. commands will fail if more than one
element is found that matches the criteria which is not how built-in Cypress
commands work, but is provided for closer compatibility to other Testing
Libraries.
Cypress handles actions when there is only one element found. For example, the
following will work without having to limit to only 1 returned element. The
cy.click will automatically fail if more than 1 element is returned by thefindAllByText:
`javascript`
cy.findAllByText('Some Text').click()
If you intend to enforce only 1 element is returned by a selector, the following
examples will both fail if more than one element is found.
`javascript`
cy.findAllByText('Some Text').should('have.length', 1)
cy.findByText('Some Text').should('exist')
If you would like to change the default testId from data-testId todata-test-id, add to your project's cypress/support/index.js:
`javascript``
import {configure} from '@testing-library/cypress'
configure({testIdAttribute: 'data-test-id'})
It accepts all configurations listed in
DOM testing library.
