Selecting elements:
The best practice for selecting elements on a page is to use data attribute: data-cy=”unique-value” and then cy.get('data-cy="unique_value"')

For readability use aliases:
cy.get('data-cy="unique_value"').as('some_element') then use cy.get('@some_element')

Select as jQuery element:

Why

Engineers:

  • better understanding the scope of the solution

Team:

  • faster progress in implementation
  • easier to involve new people in the project
  • limits future complications

Project:

  • clean retrospection
  • measuring progress
  • for sure, the final result started from designing will be better and faster than without one
