it blocks for test cases in Cypress - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of an it block in Cypress?

An it block defines a single test case in Cypress. It contains the steps and assertions to check if a feature works as expected.

beginner

How do you write a simple it block in Cypress?

You write it like this:<br>

it('checks page title', () => {<br>  cy.visit('https://example.com')<br>  cy.title().should('include', 'Example')<br>})

<br>This runs one test that visits a page and checks the title.

beginner

Can you have multiple it blocks inside a describe block?

Yes! A describe block groups related it blocks (test cases) together. Each it block runs independently.

beginner

What happens if an assertion inside an it block fails?

The test case fails and Cypress stops running the rest of that it block. The test report will show which it block failed and why.

beginner

Why should each it block test only one thing?

Testing one thing per it block keeps tests simple and clear. It helps find exactly what broke when a test fails, making debugging easier.

What does an it block represent in Cypress?

A A single test case

B A group of test cases

C A setup step before tests

D A cleanup step after tests

An it block defines one test case with steps and assertions.

Where do you place multiple it blocks to organize tests?

A Inside another <code>it</code> block

B Inside a <code>describe</code> block

C Outside any block

D Inside a <code>beforeEach</code> block

describe blocks group related it blocks.

What happens if an assertion fails inside an it block?

A The test case fails and stops running

B The test case passes anyway

C The whole test suite stops

D The assertion is ignored

A failed assertion causes the current it block to fail and stop.

Why is it best to test only one thing per it block?

A To skip tests easily

B To run tests faster

C To keep tests simple and easy to debug

D To avoid writing assertions

One test per it block helps find problems quickly.

Which of these is a correct it block syntax in Cypress?

A it(() => { cy.visit('/'); })

B it 'does something' { cy.visit('/'); }

C it('does something')

D it('does something', () => { cy.visit('/'); cy.get('h1').should('exist'); })

Option D shows the correct syntax with a description and a function.

Explain what an it block does in Cypress and why it is important.

Think about how you write one test in Cypress.

Describe how you organize multiple it blocks in Cypress and the benefit of this organization.

Consider how you group similar tests in a test file.
