Automatic retry mechanism in Cypress - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of the automatic retry mechanism in Cypress?

It helps Cypress automatically retry commands and assertions until they pass or a timeout occurs, making tests more stable and reliable.

beginner

Which Cypress commands benefit from automatic retries?

Commands like cy.get(), cy.contains(), and assertions such as should() are automatically retried until they pass or timeout.

How does Cypress decide when to stop retrying a command?

Cypress stops retrying when the command or assertion passes or when the default timeout (usually 4 seconds) is reached.

How can you customize the retry timeout in Cypress?

You can set a custom timeout by passing the { timeout: milliseconds } option to commands, for example: cy.get('.btn', { timeout: 10000 }) retries for 10 seconds.

Why is automatic retry better than adding manual waits in tests?

Automatic retry waits only as long as needed for the condition to pass, making tests faster and less flaky compared to fixed manual waits.

What happens if a Cypress command fails initially?

A The test immediately fails without retrying.

B Cypress retries the command until it passes or times out.

C Cypress skips the command and continues.

D The test pauses and waits for manual input.

Cypress automatically retries commands and assertions until they pass or the timeout is reached.

Which of these commands does Cypress retry automatically?

A cy.task()

B cy.log()

C cy.exec()

D cy.get()

cy.get() is retried automatically; commands like cy.log() do not retry.

How can you increase the retry timeout for a specific command?

A By adding <code>{ timeout: value }</code> option to the command

B By changing the global Cypress config only

C By adding <code>cy.wait()</code> before the command

D By disabling retries in Cypress

You can pass a timeout option directly to commands to customize retry duration.

What is the default timeout for retries in Cypress?

A 4 seconds

B 10 seconds

C 1 second

D No timeout, retries forever

By default, Cypress retries commands for up to 4 seconds before failing.

Why should you avoid using fixed waits instead of relying on automatic retries?

A Fixed waits are required for retries to work.

B Fixed waits make tests faster.

C Fixed waits slow down tests and can cause flakiness.

D Automatic retries do not work with dynamic content.

Fixed waits add unnecessary delay and can cause flaky tests; automatic retries wait only as long as needed.

Explain how Cypress automatic retry mechanism improves test reliability.

Think about how waiting for elements or conditions works in real life.

Describe how to customize retry timeout for a Cypress command and why you might do it.

Consider a slow website or network delay scenario.
