    cypress-react-selector is a lightweight plugin to help you to locate web elements in your REACT app using components, props and states. This extension allow you to select elements in a way that is native to React. Designed to help developers in component, integration and E2E testing.

    Internally, cypress-react-selector uses a library called resq to query React's VirtualDOM in order to retrieve the nodes.

    Install and configure

    Add as a dependency:

    npm i --save cypress-react-selector

    Include the commands

    Update Cypress/support/index.js file to include the cypress-react-selector commands by adding:

    import 'cypress-react-selector';

    TSConfig Settings for types

      "compilerOptions": {
        "sourceType": "module",
        "types": ["node", "cypress", "cypress-react-selector"]


    • cypress-react-selector supports NodeJS 8 or higher
    • It supports React 16 or higher
    • Retries each interaction until timeout to handle asynchronous calls
    • Supports shadow DOM
    • Supports wildcard selection for component names
    • Supports nested Props
    • Supports assertion on real-time react properties (props and states)

    How to use React Selector?

    Lets take this example REACT APP:

    // imports
    const MyComponent = ({ someBooleanProp }) => (
      <div>My Component {someBooleanProp ? 'show this' : ''} </div>
    const App = () => (
      <div id="root">
        <MyComponent />
        <MyComponent someBooleanProp={true} />
    ReactDOM.render(<App />, document.getElementById('root'));

    Wait for application to be ready to run tests

    cypress-react-selector needs the react root css-selector information to identify

    • Whether React has loaded
    • Retry React identification queries if state changes in run time/React loads asynchronously

    In order to make sure that the React component tree has loaded, add the waitForReact call immediately after loading a page. Here is an example where it's done in the fixture's before hook.

    before(() => {
      cy.waitForReact(1000, '#root'); // 1000 is the timeout in milliseconds, you can provide as per AUT

    NOTE : The Best Configuration for React root is to declare it as an env variable

    We always recommend to declare the react root as a env variable in the cypress.json file. It is a best approach rather than passing react root information to waitForReact method every time.

    As an example:

      "env": {
        "cypress-react-selector": {
          "root": "#root"

    If you choose to declare the root selector as a configuration, then you will have the freedom to call waitForReact method without passing the root parameter.

    before(() => {

    NOTE: If you are using Webpack with your project, you may need to manually pass in the resq module path.

    There's an optional parameter in waitForReact that can be passed in at runtime.

    This should be the path of the resq entrypoint

    before(() => {
      cy.waitForReact(1000, '#root', 'node_modules/resq/dist/index.js'); // Manually passing in the resq module path

    Find Element by React Component

    You should have React Develop Tool installed to spy and find out the component name as sometimes components can go though modifications. Once the React gets loaded, you can easily identify an web element by react component name:

    // you can have your assertions chained like
    it('it should validate react selection with component name', () => {
      cy.react('MyComponent').should('have.length', '1');

    Element filtration by Props and States

    You can filter the REACT components by its props and states like below:

    cy.react(componentName, reactOpts);
    // ReactOpts:
    //  props: { someProp: someValue },
    //  state: { someState: someValue },
    //  exact: boolean
    // for the example APP
    cy.react('MyComponent', { props: { name: 'John' } });

    Deep Matching with exact flag

    If you are in need of matching exactly every property and value in the object (or nested objects), you can pass the exact flag to the cy.react or cy.getReact function:

    cy.react('MyComponent', { props: { name: 'John' }, exact: true });

    Make sure all the props and/or state are listed while using this flag, if not matched it will return undefined

    Wildcard selection

    You can select your components by partial name use a wildcard selectors:

    // Partial Match
    cy.react('My*', { props: { name: 'John' } });
    // Entire Match
    cy.react('*', { props: { name: 'John' } }); // return all components matched with the prop

    Find element by nested props

    Let's suppose you have an Form component

      <Field name="email" type="email" component={MyTextInput} />
      <ErrorMessage name="email" component="div" />
      <br />
      <Field type="password" name="password" component={MyTextInput} />
      <ErrorMessage name="password" component="div" />
      <br />
      <button type="submit" disabled={isSubmitting}>

    And MyTextInput component is developed as:

    const MyTextInput = (props) => {
      const { field, type } = props;
      return (
        <input {...field} type={type} placeholder={'ENTER YOUR ' +} />

    then you can use cypress-react-selector to identify the element with nested props

    it('enter data into the fields', () => {
      cy.react('MyTextInput', { props: { field: { name: 'email' } } }).type(
      cy.react('MyTextInput', { props: { field: { name: 'password' } } }).type(

    Get React Properties from element

    Let's take same Form example

    Get Props

    You can get the React properties from a React element and validate the properties run time.

    // set the email in the form
    cy.react('MyTextInput', { props: { field: { name: 'email' } } }).type(
    // validate the property runtime
    cy.getReact('MyTextInput', { props: { field: { name: 'email' } } })
      .should('eq', '');
    // to get all the props, simply do not pass anything in getProps() method
    cy.getReact('MyTextInput', { props: { field: { name: 'email' } } }).getProps();


    Get current state

    cy.getReact('MyTextInput', {
      props: { field: { name: 'email' } },
    }).getCurrentState(); // can return string | boolean | any[] | {}


    You can configure the timeouts in the cypress.json configuration file. Alternatively, you can also pass the timeout as a object literal in the react commands like,

    cy.react('MyComponent', { options: { timeout: 50000 } });

    Fetch indexed node

    1. cy.react returns DOM element, so you can fetch the indexed node by .eq(index), like:
    1. cy.getReact() return RESQ node, so you can't fetch it through .eq(). You need to use .nthNode(index), like:
      .should('eq', 'First Item');

    Use fluent chained queries

    You can chain react-selector queries like:

    • combine with cypress native element .find() -
    cy.react('FormComponent').find('input').type('buy milk');
    • fetch HTMLElements by chained react queries
    cy.react('MyComponent', { props: { name: 'Bob' } })
      .should('have.text', '50');
    • fetch react props and states by chained getReact query
    cy.getReact('MyComponent', { props: { name: 'Bob' } })
      .should('eq', '50');

    ⚠️ Fluent commands are not working in some special cases. It is being tracked here

    Tool You Need

    React-Dev-Tool — You can inspect the DOM element by simply pressing the f12. But, to inspect REACT components and props, you need to install the chrome plugin.
