How do I use assertions in Cypress for Vue testing?

In Cypress, you can use assertions to verify that your Vue components behave as expected. You can use commands like cy.get() to select elements and then chain assertions like .should('be.visible') or .should('have.text', 'expected text').

Can you give me an example of an assertion for a button?

Sure! If you have a button with the class .submit-btn, you can check if it's visible and enabled like this:

cy.get('.submit-btn')
  .should('be.visible')
  .should('not.be.disabled');

What about testing the output of a computed property?

To test a computed property, you can set the component's data and then assert the computed value. For example:

cy.get('.computed-output')
  .should('have.text', 'expected computed value');

Are there any best practices for writing assertions?

Yes! Some best practices include keeping assertions clear and concise, grouping related assertions, and using custom commands for repetitive checks.
