cy.contains() for text matching in Cypress - Test Execution Trace

Test Overview

This test checks if a button with specific text is present on the page and clicks it. It verifies that the button click triggers the expected change in the page content.

Test Code - Cypress

Cypress

describe('Test cy.contains() for text matching', () => {
  it('Finds button by text and clicks it', () => {
    cy.visit('https://example.cypress.io')
    cy.contains('type').click()
    cy.url().should('include', '/commands/actions')
    cy.get('.action-email').should('be.visible')
  })
})

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Test runner initialized, no browser opened yet	—	PASS
2	Browser opens and navigates to 'https://example.cypress.io'	Browser shows the Cypress example homepage	—	PASS
3	Finds element containing text 'type' using cy.contains('type')	Button or link with text 'type' is visible on the page	Element with text 'type' is found	PASS
4	Clicks the element found by cy.contains('type')	Page navigates to '/commands/actions' section	URL includes '/commands/actions'	PASS
5	Finds input element with class '.action-email' and checks visibility	Input field for email is visible on the page	Element '.action-email' is visible	PASS

Failure Scenario

Failing Condition: The text 'type' is not found on the page, so cy.contains() fails to find the element

Execution Trace Quiz - 3 Questions

What does cy.contains('type') do in this test?

A Finds an element with the class 'type'

B Finds an element with the id 'type'

C Finds an element that has the text 'type' anywhere inside it

D Finds an element with the attribute type='button'

Key Result

Using cy.contains() is a simple and readable way to find elements by their visible text, making tests easier to write and understand.

Practice

1. What does cy.contains('Submit') do in a Cypress test?

easy

A. Finds the first element containing the visible text 'Submit'.

B. Clicks the button named 'Submit' automatically.

C. Types 'Submit' into an input field.

D. Checks if the page URL contains the word 'Submit'.

Solution

1. Step 1: Understand cy.contains() basic function

   The command searches the page for an element that has visible text matching the given string.

2. Step 2: Analyze the given text 'Submit'

   It finds the first element that contains the text 'Submit' anywhere inside it.

3. Final Answer:

   Finds the first element containing the visible text 'Submit'. -> Option A

4. Quick Check:

   cy.contains('text') finds element by visible text [OK]

Hint: cy.contains() finds elements by visible text quickly [OK]

Common Mistakes:

• Thinking cy.contains() clicks automatically
• Confusing cy.contains() with typing commands
• Assuming it checks URL instead of page content

2. Which of the following is the correct syntax to find a button with text 'Login' using cy.contains()?

easy

A. cy.contains(button, Login)

B. cy.contains('button', 'Login')

C. cy.contains('Login', 'button')

D. cy.contains('button' + 'Login')

Solution

1. Step 1: Recall cy.contains() syntax with selector

   The correct syntax is cy.contains(selector, text) where selector is a string like 'button'.

2. Step 2: Match the correct option

   cy.contains('button', 'Login') uses cy.contains('button', 'Login') which is correct. Other options misuse quotes or argument order.

3. Final Answer:

   cy.contains('button', 'Login') -> Option B

4. Quick Check:

   cy.contains('selector', 'text') correct syntax [OK]

Hint: Use cy.contains('selector', 'text') to narrow search [OK]

Common Mistakes:

• Omitting quotes around selector or text
• Swapping the order of selector and text
• Concatenating strings incorrectly inside cy.contains()

3. What will the following Cypress code do?

cy.contains('Submit').click()

medium

A. Types 'Submit' into the focused input field.

B. Throws an error because click() cannot be chained.

C. Finds the first element with text 'Submit' and clicks it.

D. Finds all elements with 'Submit' text but does not click.

Solution

1. Step 1: Understand cy.contains() chaining

   cy.contains('Submit') finds the first element with visible text 'Submit'.

2. Step 2: Analyze the chained click()

   Calling .click() on the found element triggers a click event on it.

3. Final Answer:

   Finds the first element with text 'Submit' and clicks it. -> Option C

4. Quick Check:

   cy.contains('text').click() clicks matched element [OK]

Hint: Chain .click() after cy.contains() to click element [OK]

Common Mistakes:

• Thinking click() types text instead
• Assuming click() cannot be chained
• Believing it clicks multiple elements

4. You wrote cy.contains(button, 'Save').click() but the test fails with a syntax error. What is the problem?

medium

A. You must use cy.get() before cy.contains().

B. cy.contains() cannot be chained with click().

C. The text 'Save' must be uppercase.

D. The selector button should be a string: 'button'.

Solution

1. Step 1: Check argument types in cy.contains()

   The selector argument must be a string, so 'button' needs quotes.

2. Step 2: Identify the syntax error cause

   Using button without quotes causes a syntax error because it's treated as a variable.

3. Final Answer:

   The selector button should be a string: 'button'. -> Option D

4. Quick Check:

   Selector must be string in cy.contains() [OK]

Hint: Always quote selectors in cy.contains() [OK]

Common Mistakes:

• Forgetting quotes around selector
• Thinking click() can't be chained
• Assuming text case matters in cy.contains()

5. You want to verify that a page contains a link with text 'Learn More' inside a <nav> element. Which Cypress command is best?

hard

A. cy.get('nav').contains('a', 'Learn More').should('exist')

B. cy.contains('nav a', 'Learn More').click()

C. cy.contains('Learn More').should('be.visible')

D. cy.get('a').contains('nav', 'Learn More')

Solution

1. Step 1: Narrow search inside <nav> for link text

   Use cy.get('nav') to select the nav element first.

2. Step 2: Use contains() with selector 'a' and text 'Learn More'

   Calling .contains('a', 'Learn More') inside nav finds the link with that text.

3. Step 3: Assert existence with should('exist')

   This confirms the link is present inside nav.

4. Final Answer:

   cy.get('nav').contains('a', 'Learn More').should('exist') -> Option A

5. Quick Check:

   Use get() then contains() to scope text search [OK]

Hint: Use cy.get() then contains() to scope text search [OK]

Common Mistakes:

• Using contains() without scoping to nav
• Trying to chain contains() incorrectly
• Assuming contains() alone checks element existence
