should() with chainers in Cypress - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of the should() command in Cypress?

The should() command is used to make assertions about the state of elements or variables. It checks if something meets a condition and helps verify expected behavior during tests.

beginner

How do chainers work with should() in Cypress?

Chainers are words like be.visible, have.text, or contain that describe what to check. You can combine multiple chainers inside should() to check several conditions in one step.

beginner

Example: What does cy.get('button').should('be.visible').and('contain', 'Submit') check?

It checks that the button is visible on the page and that it contains the text 'Submit'. Both conditions must be true for the test to pass.

intermediate

Can you use multiple chainers inside a single should() call?

Yes, you can pass an array of chainers like should(['be.visible', 'have.class', 'active']) to check multiple conditions at once.

beginner

What happens if one of the chainers in should() fails?

If any chainer condition fails, the test will fail immediately. Cypress shows which assertion did not pass, helping you find the problem quickly.

What does should('be.visible') check in Cypress?

A If the element is disabled

B If the element is hidden

C If the element is visible on the page

D If the element contains text

should('be.visible') checks that the element is visible to the user on the page.

How can you check multiple conditions on an element using should()?

A Use multiple <code>should()</code> calls separately

B Pass an array of chainers inside one <code>should()</code>

C Use <code>expect()</code> instead

D Use <code>wait()</code> before <code>should()</code>

You can use multiple should() calls separately or chain them with and() to check multiple conditions.

What does cy.get('input').should('have.value', 'hello') verify?

A The input is empty

B The input has the value 'hello'

C The input is disabled

D The input is visible

This checks that the input element's value is exactly 'hello'.

What happens if a should() assertion fails during test execution?

A The test retries the assertion until it passes or times out

B The test skips the assertion

C The test immediately fails and stops

D The test continues ignoring the failure

Cypress retries should() assertions automatically until they pass or the timeout is reached.

Which of these is a valid chainer to use inside should()?

A type

B click

C wait

D be.visible

be.visible is a valid assertion chainer. click, wait, and type are commands, not chainers.

Explain how should() works with chainers in Cypress and why it is useful.

Think about how you check if something is true in a test.

Describe what happens when a should() assertion fails and how Cypress handles it.

Consider how Cypress waits and retries assertions.
