cypress-real-events for native events - Test Execution Trace

Test Overview

This test uses the cypress-real-events plugin to simulate a native click event on a button. It verifies that the button's click handler is triggered and the expected text appears on the page.

Test Code - Cypress

Cypress

import 'cypress-real-events/support';

describe('Native click event test with cypress-real-events', () => {
  it('should trigger native click and show confirmation text', () => {
    cy.visit('https://example.cypress.io/commands/actions');
    cy.get('.action-btn').realClick();
    cy.get('.action-btn').should('have.class', 'clicked');
    cy.get('#action-callback').should('contain.text', 'Button clicked');
  });
});

Execution Trace - 6 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Cypress test runner is ready	—	PASS
2	Browser opens and navigates to https://example.cypress.io/commands/actions	Page with action buttons is loaded	Page URL is correct	PASS
3	Find element with class '.action-btn'	Button element is visible and enabled	Element exists and is visible	PASS
4	Perform native click on the button using realClick()	Button receives native click event	—	PASS
5	Check if button has class 'clicked' after click	Button class list updated to include 'clicked'	Button has class 'clicked'	PASS
6	Check if element with id '#action-callback' contains text 'Button clicked'	Confirmation text is displayed on page	Text 'Button clicked' is present	PASS

Failure Scenario

Failing Condition: The button is not found or the native click event does not trigger the expected changes

Execution Trace Quiz - 3 Questions

What does the realClick() command do in this test?

A Scrolls the element into view without clicking

B Simulates a native browser click event on the element

C Triggers a JavaScript click event without user interaction

D Waits for the element to be visible

Key Result

Using cypress-real-events allows tests to simulate real user interactions more accurately by triggering native browser events, which helps catch issues that synthetic events might miss.

Practice

1. What is the main purpose of using cypress-real-events in Cypress tests?

easy

A. To generate random test data automatically

B. To speed up test execution by skipping events

C. To simulate real native browser events like clicks and typing

D. To replace Cypress commands with custom assertions

Solution

1. Step 1: Understand the role of native events in UI testing

   Native events like clicks and typing trigger real browser behaviors that Cypress commands sometimes do not fully simulate.

2. Step 2: Identify what cypress-real-events provides

   This plugin sends real native events to elements, improving test accuracy and reliability.

3. Final Answer:

   To simulate real native browser events like clicks and typing -> Option C

4. Quick Check:

   Native event simulation = C [OK]

Hint: Remember: real-events means real user-like browser events [OK]

Common Mistakes:

• Thinking it speeds up tests by skipping events
• Confusing it with data generation tools
• Assuming it replaces assertions

2. Which of the following is the correct syntax to import and use realClick from cypress-real-events in a test?

easy

A. import { realClick } from 'cypress-real-events'; cy.get('button').realClick();

B. import realClick from 'cypress-real-events'; cy.realClick('button');

C. require('cypress-real-events').realClick('button');

D. cy.get('button').clickReal();

Solution

1. Step 1: Check the correct import style for ES modules

   The plugin exports named functions, so use import { realClick } from 'cypress-real-events'.

2. Step 2: Use the function on a Cypress element

   Call realClick() on the element returned by cy.get().

3. Final Answer:

   import { realClick } from 'cypress-real-events'; cy.get('button').realClick(); -> Option A

4. Quick Check:

   Named import + method on element = B [OK]

Hint: Use named imports and call on element chain [OK]

Common Mistakes:

• Using default import instead of named import
• Calling realClick directly on cy object
• Using require syntax in ES module context

3. Given the code below, what will be the result of the test?

cy.get('#input').realType('Hello');
cy.get('#input').should('have.value', 'Hello');

medium

A. The test passes because realType types the text correctly

B. The test fails because realType does not change input value

C. The test throws a syntax error due to wrong method name

D. The test passes but input value is empty

Solution

1. Step 1: Understand what realType does

   realType sends native keyboard events to type text into input fields, updating their value.

2. Step 2: Check the assertion

   The assertion checks if the input's value matches the typed text, which should be true after realType.

3. Final Answer:

   The test passes because realType types the text correctly -> Option A

4. Quick Check:

   realType updates input value = D [OK]

Hint: realType simulates typing, so input value updates [OK]

Common Mistakes:

• Assuming realType does not affect input value
• Confusing realType with click methods
• Expecting syntax errors from correct method

4. You wrote this test but it fails:

cy.get('#submit').realClick();

What is the most likely reason for failure?

medium

A. The selector '#submit' is invalid syntax

B. realClick is not a valid method in cypress-real-events

C. You forgot to import Cypress

D. The element is not visible or not interactable

Solution

1. Step 1: Check if element is visible and interactable

   realClick requires the element to be visible and enabled to send native click events.

2. Step 2: Verify method and selector correctness

   realClick is valid and selector syntax is correct, so these are unlikely causes.

3. Final Answer:

   The element is not visible or not interactable -> Option D

4. Quick Check:

   Element visibility needed for realClick = A [OK]

Hint: Check element visibility before realClick [OK]

Common Mistakes:

• Assuming realClick method does not exist
• Blaming selector syntax without checking visibility
• Forgetting to import cypress-real-events functions

5. You want to test a hover tooltip that only appears on a real mouse hover event. Which cypress-real-events method should you use to trigger this tooltip reliably?

hard

A. realClick()

B. realHover()

C. realType()

D. realFocus()

Solution

1. Step 1: Identify the event that triggers the tooltip

   Tooltips often appear on mouse hover events, which require a real mouseover or hover event.

2. Step 2: Match the correct cypress-real-events method

   realHover() sends native mouse hover events, triggering tooltips reliably.

3. Final Answer:

   realHover() -> Option B

4. Quick Check:

   Hover event needs realHover() = A [OK]

Hint: Use realHover() to simulate mouse hover events [OK]

Common Mistakes:

• Using realClick() instead of realHover() for hover effects
• Trying realType() which types text, not hover
• Using realFocus() which focuses but doesn't hover
