cy.fixture() for loading data in Cypress - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is cy.fixture() used for in Cypress?

cy.fixture() is used to load external fixed data files (like JSON) to use in tests. It helps keep test data separate from test code.

How do you load a JSON fixture file named user.json in Cypress?

You use cy.fixture('user').then((data) => { ... }) to load the file and access its contents inside the then callback.

Why is using cy.fixture() better than hardcoding test data inside tests?

It separates data from code, making tests cleaner and easier to maintain. You can reuse data and update it without changing test logic.

intermediate

Can cy.fixture() load non-JSON files?

Yes, it can load text, CSV, or other file types as strings if you specify the correct encoding or parse them manually.

beginner

How do you use fixture data inside a test to fill a form?

Load the fixture with cy.fixture(), then use the data inside commands like cy.get(...).type(data.field) to fill form fields.

What does cy.fixture('data.json') return?

A A promise with the file content

B A DOM element

C A Cypress command chain

D An error

cy.fixture() returns a Cypress command chain that yields the file content.

Where should fixture files be placed in a Cypress project?

A cypress/support folder

B cypress/fixtures folder

C root folder

D cypress/integration folder

Fixture files belong in the cypress/fixtures folder by default.

How do you access fixture data inside a test?

A Using <code>cy.get()</code>

B Directly calling the file name

C Using <code>cy.visit()</code>

D Using <code>cy.fixture().then()</code>

You use cy.fixture('file').then((data) => { ... }) to access the data.

Which of these is a benefit of using cy.fixture()?

A Separates test data from test code

B Runs tests faster

C Automatically generates test data

D Replaces <code>cy.visit()</code>

Fixtures help keep test data separate from test code for clarity and reuse.

If you want to load a fixture file as plain text, what should you do?

A Pass encoding option to <code>cy.fixture()</code>

B Use <code>cy.readFile()</code> instead

C Rename the file to .txt

D Fixtures only support JSON

You can pass an encoding option like { encoding: 'utf-8' } to load as text.

Explain how to use cy.fixture() to load test data and use it in a Cypress test.

Think about loading JSON files and using their content inside your test steps.

Describe the advantages of using fixtures for test data in Cypress.

Consider how managing data separately helps when tests grow.
