Cypress architecture (runs in browser) - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main environment where Cypress tests run?

Cypress tests run directly inside the browser, the same place where your application runs. This allows Cypress to control and observe the app closely.

intermediate

How does Cypress communicate with the browser during test execution?

Cypress uses a special server and a driver inside the browser to send commands and receive information, enabling real-time control and feedback.

beginner

Why is running tests inside the browser beneficial in Cypress?

Running tests inside the browser lets Cypress see everything the user sees, making it easier to catch UI bugs and interact with the app naturally.

beginner

What role does the Cypress Test Runner play in the architecture?

The Test Runner is the user interface that shows tests running in real time inside the browser, letting you watch commands and app behavior step-by-step.

intermediate

Explain how Cypress handles asynchronous commands in its architecture.

Cypress queues commands and runs them one by one inside the browser, automatically waiting for each to finish before moving on, so you don't need manual waits.

Where do Cypress tests execute?

A Inside the browser alongside the application

B On a separate server outside the browser

C Only in the command line interface

D In a virtual machine

Cypress runs tests inside the browser, allowing direct interaction with the app.

What does the Cypress Test Runner display?

A Only test results summary

B Database queries

C Server logs

D Real-time test execution inside the browser

The Test Runner shows tests running live inside the browser with detailed command info.

How does Cypress handle waiting for commands to finish?

A Runs all commands simultaneously

B Requires manual wait commands

C Automatically queues and waits for each command

D Ignores command completion

Cypress automatically queues commands and waits for each to complete before continuing.

Which component helps Cypress communicate with the browser?

A Command line tool

B Browser driver inside the browser

C Database connector

D External API server

Cypress uses a driver inside the browser to send and receive commands.

Why is running tests inside the browser useful?

A It allows direct observation and control of the app

B It speeds up server response

C It reduces browser memory usage

D It hides the app from the user

Running tests inside the browser lets Cypress see and control the app like a real user.

Describe the main components of Cypress architecture and how they work together inside the browser.

Think about how Cypress controls the app and shows test progress.

Explain why Cypress running tests inside the browser is different from other testing tools.

Compare Cypress to tools that run tests outside the browser.
