cy.check() and cy.uncheck() in Cypress - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does cy.check() do in Cypress?

cy.check() selects a checkbox or radio button, simulating a user clicking to check it.

beginner

How do you uncheck a checkbox using Cypress?

You use cy.uncheck() to unselect a checkbox, simulating a user clicking to remove the check.

beginner

Can cy.check() be used on radio buttons?

Yes, cy.check() works on both checkboxes and radio buttons to select them.

What happens if you use cy.uncheck() on a radio button?

cy.uncheck() does not work on radio buttons because radios cannot be unchecked by user action once selected.

intermediate

Why is it important to use cy.check() and cy.uncheck() instead of click() for checkboxes?

Because cy.check() and cy.uncheck() ensure the checkbox state changes correctly and trigger related events, while click() might not always do this reliably.

Which Cypress command selects a checkbox?

A cy.select()

B cy.uncheck()

C cy.click()

D cy.check()

cy.check() is used to select checkboxes or radio buttons.

What does cy.uncheck() do?

A Clicks a button

B Selects a radio button

C Unselects a checkbox

D Types text into input

cy.uncheck() unselects a checkbox by simulating user unchecking it.

Can cy.uncheck() be used on radio buttons?

A Yes, it unchecks radios

B No, radios cannot be unchecked by user

C Yes, but only if forced

D Only on disabled radios

Radio buttons cannot be unchecked by user action, so cy.uncheck() does not work on them.

Why prefer cy.check() over cy.click() for checkboxes?

A It triggers proper events and state changes

B It is faster

C It works only on radios

D It disables the checkbox

cy.check() ensures the checkbox state changes correctly and triggers related events, unlike click().

Which command would you use to select a radio button in Cypress?

A cy.check()

B cy.selectRadio()

C cy.uncheck()

D cy.clickRadio()

cy.check() works for both checkboxes and radio buttons to select them.

Explain how cy.check() and cy.uncheck() work in Cypress and when to use each.

Think about user actions on checkboxes and radios.

Describe why using cy.check() and cy.uncheck() is better than using cy.click() for checkboxes.

Consider event triggering and state consistency.

Practice

1. What does cy.check() do in Cypress testing?

easy

A. Deselects checkboxes only

B. Clicks buttons on the page

C. Selects checkboxes or radio buttons

D. Types text into input fields

Solution

1. Step 1: Understand the purpose of cy.check()

   cy.check() is used to select checkboxes or radio buttons in Cypress tests.

2. Step 2: Compare with other commands

   cy.uncheck() is used to deselect checkboxes only, so it does not match the question.

3. Final Answer:

   Selects checkboxes or radio buttons -> Option C

4. Quick Check:

   cy.check() selects inputs [OK]

Hint: Remember: check() selects, uncheck() deselects checkboxes [OK]

Common Mistakes:

• Confusing cy.check() with cy.uncheck()
• Thinking cy.check() types text
• Assuming cy.check() clicks buttons

2. Which of the following is the correct syntax to uncheck a checkbox with id agree in Cypress?

easy

A. cy.get('#agree').uncheck()

B. cy.get('#agree').check()

C. cy.get('#agree').click()

D. cy.get('#agree').type('uncheck')

Solution

1. Step 1: Identify the command to deselect a checkbox

   To deselect a checkbox, use cy.uncheck().

2. Step 2: Match the syntax with the element selector

   cy.get('#agree').uncheck() correctly targets the checkbox with id 'agree' and unchecks it.

3. Final Answer:

   cy.get('#agree').uncheck() -> Option A

4. Quick Check:

   uncheck() deselects checkbox [OK]

Hint: Use uncheck() only to deselect checkboxes [OK]

Common Mistakes:

• Using check() to uncheck a box
• Using click() which may toggle unpredictably
• Trying to type 'uncheck' into checkbox

3. Given the following code snippet, what will be the assertion result?

cy.get('input[type="checkbox"]').check().should('be.checked');
cy.get('input[type="checkbox"]').uncheck().should('not.be.checked');

medium

A. First assertion passes, second fails

B. Both assertions pass

C. First assertion fails, second passes

D. Both assertions fail

Solution

1. Step 1: Analyze the first command and assertion

   cy.get('input[type="checkbox"]').check() selects all checkboxes, then should('be.checked') asserts they are checked. This should pass.

2. Step 2: Analyze the second command and assertion

   cy.get('input[type="checkbox"]').uncheck() deselects all checkboxes, then should('not.be.checked') asserts they are unchecked. This should also pass.

3. Final Answer:

   Both assertions pass -> Option B

4. Quick Check:

   check() then be.checked, uncheck() then not.be.checked [OK]

Hint: check() sets checked, uncheck() clears checked [OK]

Common Mistakes:

• Assuming uncheck() works on radio buttons
• Thinking check() does not affect checked state
• Confusing assertion syntax

4. You wrote this Cypress test:

cy.get('input[type="radio"]').uncheck();

Why does this test fail?

medium

A. Because radio buttons cannot be selected

B. Because the selector is incorrect

C. Because uncheck() requires a parameter

D. Because uncheck() cannot be used on radio buttons

Solution

1. Step 1: Understand uncheck() limitations

   uncheck() works only on checkboxes, not radio buttons.

2. Step 2: Analyze the selector and usage

   The selector targets radio buttons, so using uncheck() causes failure.

3. Final Answer:

   Because uncheck() cannot be used on radio buttons -> Option D

4. Quick Check:

   uncheck() only for checkboxes [OK]

Hint: Use uncheck() only on checkboxes, not radios [OK]

Common Mistakes:

• Trying to uncheck radio buttons
• Assuming uncheck() needs parameters
• Confusing selector correctness

5. You want to test a form with multiple checkboxes named features. You want to check only the boxes with values fast and secure, then verify only those are checked. Which Cypress code snippet correctly does this?

hard

A. cy.get('input[name="features"]').check(['fast', 'secure']).should('be.checked')

B. cy.get('input[name="features"]').check('fast').check('secure').should('be.checked')

C. cy.get('input[name="features"]').check(['fast', 'secure']).should('have.value', ['fast', 'secure'])

D. cy.get('input[name="features"]').check(['fast', 'secure']).should('be.checked').uncheck('fast')

Solution

1. Step 1: Use check() with array to select multiple checkboxes

   cy.get('input[name="features"]').check(['fast', 'secure']) checks the boxes with those values.

2. Step 2: Assert that those checkboxes are checked

   should('be.checked') confirms the selected checkboxes are checked.

3. Final Answer:

   cy.get('input[name="features"]').check(['fast', 'secure']).should('be.checked') -> Option A

4. Quick Check:

   check(array) selects multiple, then assert checked [OK]

Hint: Use check(['val1','val2']) to select multiple checkboxes [OK]

Common Mistakes:

• Using multiple check() calls without chaining properly
• Using should('have.value') which is incorrect for checkboxes
• Unchecking after checking without reason
