Why Cypress auto-retries reduce flakiness - Test Execution Impact

Test Overview

This test checks that a button becomes visible and clickable after a delay. It verifies Cypress auto-retries help reduce flaky failures by waiting and retrying the element check before clicking.

Test Code - Cypress

Cypress

describe('Auto-retry reduces flakiness', () => {
  it('waits for button to appear and clicks it', () => {
    cy.visit('https://example.com/delayed-button')
    cy.get('#delayed-btn').should('be.visible').click()
    cy.get('#message').should('contain.text', 'Button clicked!')
  })
})

Execution Trace - 7 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Test runner initialized, browser ready	-	PASS
2	Browser opens and navigates to 'https://example.com/delayed-button'	Page loads with delayed button element not yet visible	-	PASS
3	Cypress tries to find element with selector '#delayed-btn'	Button element exists in DOM but is hidden initially	Check if '#delayed-btn' is visible	PENDING
4	Cypress auto-retries finding '#delayed-btn' and checking visibility multiple times	Button becomes visible after a short delay	Verify '#delayed-btn' is visible	PASS
5	Cypress clicks the '#delayed-btn' button	Button is visible and clickable	-	PASS
6	Cypress checks that '#message' contains text 'Button clicked!'	Message element shows confirmation text	Verify '#message' contains 'Button clicked!'	PASS
7	Test ends successfully	All assertions passed, test complete	-	PASS

Failure Scenario

Failing Condition: Button '#delayed-btn' never becomes visible within Cypress default timeout

Execution Trace Quiz - 3 Questions

What does Cypress do when '#delayed-btn' is not immediately visible?

A It skips the test step

B It fails the test immediately

C It retries finding and checking visibility until timeout

D It refreshes the page automatically

Key Result

Using Cypress auto-retries for element checks helps tests wait for dynamic page changes, reducing flaky failures caused by timing issues.
