Should read assertion

This assertion comes from the cypress-map plugin. It is useful for checking the text content of list of elements against strings or regular expressions.

<ul id="todos">
  <li>Write code</li>
  <li>Add tests</li>
  <li>Pay $10 fine</li>
</ul>

Let's confirm the exact text of the first LI element:

cy.get('li').first().should('have.text', 'Write code')

We can confirm partial text using cy.contains

cy.contains('li', 'Add').should('have.text', 'Add tests')

To confirm multiple exact text matches, you can use the should read custom assertion from the cypress-map plugin

cy.get('li').should('read', [
  'Write code',
  'Add tests',
  'Pay $10 fine',
])

You can use either exact text matches or match against regular expressions. For example, if we do not know the precise fine amount, we could use:

cy.get('li').should('read', [
  'Write code',
  'Add tests',
  /^Pay \$\d+ fine$/,
])
