Testing With Cypress

The AudioEye Accessibility Testing SDK Cypress Library gives you the ability to write Cypress tests to test for accessibility issues in your web application.

Pre-requisites​

Visit the Getting Started page to learn how to setup Cypress in your project.

Usage​

Use the available tests to test for accessibility issues in your Cypress tests.

describe('accessibility tests', () => {
  it('accessibility for the entire page matches our expectation', () => {
    cy.visit('http://localhost:3000');

    // For full page scan that uses the root element, we need to "get" something first otherwise the page won't be settled
    cy.get('[data-cy="login"]').should('contain', 'Join or Login');

    cy.get('html:root').then((htmlRootElement) => {
      expect(htmlRootElement).to.findAccessibilityIssues();
      expect(htmlRootElement).to.findTheseAccessibilityIssues('Img_Name_Missing');
      expect(htmlRootElement).to.onlyHaveTheseAccessibilityIssues(
        'Img_Name_Missing',
        'Text_Contrast_TooLow',
        'Html_Possible_Heading',
      );
    });
  });

  it('accessibility for the login button matches our expectation', () => {
    cy.visit('http://localhost:3000');

    cy.get('[data-cy="login"]').then((button) => expect(button).to.not.findAccessibilityIssues());
  });
});

Available Tests​

findAccessibilityIssues​

Use .findAccessibilityIssues when checking if a component has accessibility issues.

it('expect to find accessibility issues on the page', () => {
  cy.visit('http://localhost:3000');
  cy.get('html:root').then((htmlRootElement) => expect(htmlRootElement).to.findAccessibilityIssues());
});
it('expect to find no accessibility issues on the page', () => {
  cy.visit('http://localhost:3000');
  cy.get('html:root').then((htmlRootElement) => expect(htmlRootElement).to.not.findAccessibilityIssues());
});

onlyHaveTheseAccessibilityIssues​

Use .onlyHaveTheseAccessibilityIssues when checking if a component has exactly the same issues as those expected. Pass a comma separated list of expected test names.

it('expect to find an accessibility issues when no alt-text is passed to component', () => {
  cy.visit('http://localhost:3000');
  cy.get('[data-cy="company-logo"]').then((htmlRootElement) =>
    expect(htmlRootElement).to.onlyHaveTheseAccessibilityIssues('Img_Name_Missing'),
  );
});

findTheseAccessibilityIssues​

Use .findTheseAccessibilityIssues when checking if a component's accessibility issues includes the issues expected. Pass a comma separated list of expected test names.

it('expect to find an alt-text accessibility issue', () => {
  cy.visit('http://localhost:3000');
  cy.get('[data-cy="company-logo"]').then((htmlRootElement) =>
    expect(htmlRootElement).to.findTheseAccessibilityIssues('Img_Name_Missing'),
  );
});
it('expect to not find an alt-text accessibility issue', () => {
  cy.visit('http://localhost:3000');
  const descriptiveImage = await promisify(cy.get(''));
  cy.get('[data-cy="descriptive-image"]').then((htmlRootElement) => expect(htmlRootElement).to.not.findTheseAccessibilityIssues('Img_Name_Missing'));
});
