How to use Cypress to perform a Google search


This article goes over how to perform a Google search using the Cypress end-to-end (E2E) test runner. See the YouTube video:

Prerequisites

Install

Install cypress with npm or yarn:

npm install cypress

Open

Open Cypress:

npx cypress open

Cypress integration tests

The directories will be created:

tree cypress -L 1
cypress
├── fixtures
├── integration
├── plugins
└── support

4 directories, 0 files

To run a test, click on the test file:

Cypress actions spec

Example

Create file cypress/integration/example.js:

touch cypress/integration/example.js

Write the test:

it('should pass', () => {
  expect(true).to.equal(true);
});

Click on the test so it runs in a new browser window:

Cypress example test

Cypress uses Mocha as the test runner and Chai as the assertion library.

Create file cypress/integration/google-search.js:

touch cypress/integration/google-search.js

Use visit to open a page:

cy.visit('https://www.google.com');

Use get to select a DOM element:

cy.get('input[name="q"]');

The querying behavior is similar to jQuery’s $().

Click Open Selector Playground to try out different selectors:

Click an element or use the browser Inspect tool to get a good selector:

Cypress get selector

Use type to input text and keyboard actions:

cy.get('input[name="q"]').type('remarkablemark{enter}');

{enter} types the Enter key.

An alternative to typing the Enter key is to submit the form:

cy.get('form').submit();

Or to click the search button:

cy.get('input[value="Google Search"]').first().click();

Use invoke to get the first search URL:

cy.get('#search a')
  .first()
  .invoke('attr', 'href')
  .then(href => console.log(href));

then is used to yield the promise value since the command is asynchronous.

Code

describe('Google Search', () => {
  it('loads search page', () => {
    cy.visit('https://www.google.com');
  });

  it('searches for `remarkablemark`', () => {
    cy.get('input[name="q"]').type('remarkablemark{enter}');
  });

  it('gets first search result', () => {
    cy.get('#search a')
      .invoke('attr', 'href')
      .then(href => console.log(href));
  });
});
