Practice - 5 Tasks

1fill in blank

easy

Complete the code to select an element with the class button using cy.get().

Cypress

cy.get('[1]')

Drag options to blanks, or click blank then click option'

A.button

B#button

Cbutton

D*button

💡 Hint

Common Mistakes

Using '#' which selects by id, not class.

Using the tag name without dot for class selection.

The cy.get() command uses CSS selectors. To select by class, prefix the class name with a dot .. So .button selects elements with class button.

Complete the code to select an element with the id submit using cy.get().

Cypress

cy.get('[1]')

Drag options to blanks, or click blank then click option'

A*submit

B.submit

Csubmit

D#submit

💡 Hint

Common Mistakes

Using '.' which selects by class, not id.

Using the tag name without prefix.

To select an element by its id in CSS selectors, prefix the id with a hash #. So #submit selects the element with id submit.

Fix the error in the code to select all input elements inside a form with class login.

Cypress

cy.get('form[1] input')

Drag options to blanks, or click blank then click option'

A#login

B.login

C login

D>login

Attempts:

💡 Hint

Common Mistakes

Using space without dot, which looks for a descendant named 'login'.

Using '#' which selects by id, not class.

To select elements inside a form with class login, use form.login input. The dot . indicates the class selector.

Fill both blanks to select all li elements that are direct children of a ul with class menu.

Cypress

cy.get('ul[1] [2]li')

Drag options to blanks, or click blank then click option'

A.menu

B>

D#menu

Attempts:

3 left

💡 Hint

Common Mistakes

Using space instead of > selects all descendants, not just direct children.

Using '#' instead of '.' for class.

To select direct children, use the child combinator >. To select ul with class menu, use ul.menu. So the full selector is ul.menu > li.

Fill both blanks to select all button elements with class primary inside a div with id container.

Cypress

cy.get('div[1] button[2]')

Drag options to blanks, or click blank then click option'

A#container

B.primary

D>primary

Attempts:

3 left

💡 Hint

Common Mistakes

Using '>' instead of space selects only direct children.

Using '.' instead of '#' for id selector.

The selector div#container button.primary selects button elements with class primary inside a div with id container. Spaces separate elements in the hierarchy.

Practice

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

easy

A. Starts the Cypress test runner

B. Clicks on a button automatically

C. Runs JavaScript code inside the browser

D. Finds elements on the page using CSS selectors

Solution

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

   cy.get() is used to locate elements on the web page by using CSS selectors.

2. Step 2: Differentiate from other Cypress commands

   Other commands like clicking or running code are separate; cy.get() only finds elements.

3. Final Answer:

   Finds elements on the page using CSS selectors -> Option D

4. Quick Check:

   cy.get() = Finds elements [OK]

Hint: Remember: cy.get() locates elements by CSS selectors [OK]

Common Mistakes:

• Thinking cy.get() clicks elements
• Confusing cy.get() with running scripts
• Assuming cy.get() starts tests

2. Which of the following is the correct syntax to select an element with class btn-primary using cy.get()?

easy

A. cy.get('#btn-primary')

B. cy.get('btn-primary')

C. cy.get('.btn-primary')

D. cy.get('button .btn-primary')

Solution

1. Step 1: Understand CSS selector for class

   In CSS, a class selector uses a dot before the class name, so .btn-primary selects elements with that class.

2. Step 2: Check each option

   cy.get('#btn-primary') uses an ID selector (#), which is wrong here. cy.get('btn-primary') misses the dot, so it looks for a tag named 'btn-primary'. cy.get('button .btn-primary') incorrectly uses a descendant selector (space after button), selecting buttons containing .btn-primary elements.

3. Final Answer:

   cy.get('.btn-primary') -> Option C

4. Quick Check:

   Class selector = .classname [OK]

Hint: Use dot (.) before class names in CSS selectors [OK]

Common Mistakes:

• Using # instead of . for classes
• Omitting the dot before class name
• Confusing tag selectors with class selectors

3. Given the HTML snippet:

<ul>
  <li class='item'>Apple</li>
  <li class='item'>Banana</li>
  <li class='item'>Cherry</li>
</ul>

What will cy.get('.item').should('have.length', 3) check?

medium

A. That there are exactly 3 elements with class 'item'

B. That the first element with class 'item' contains '3'

C. That the list has 3 child elements regardless of class

D. That the page has 3 lists

Solution

1. Step 1: Understand cy.get('.item')

   This selects all elements with the class 'item', which are the three <li> elements.

2. Step 2: Understand .should('have.length', 3)

   This asserts that the number of selected elements is exactly 3.

3. Final Answer:

   That there are exactly 3 elements with class 'item' -> Option A

4. Quick Check:

   cy.get('.item').length = 3 [OK]

Hint: '.should(have.length, n)' checks number of matched elements [OK]

Common Mistakes:

• Thinking it checks content inside elements
• Confusing child count with class count
• Assuming it checks number of lists

4. You wrote cy.get('button#submit').click() but the test fails with "Cannot find element" error. What is the most likely cause?

medium

A. The button does not have an ID 'submit'

B. The selector should be cy.get('#submit button')

C. You must use cy.find() instead of cy.get()

D. The click() command is not supported on buttons

Solution

1. Step 1: Analyze the selector button#submit

   This selector looks for a <button> element with ID 'submit'. If the button does not have this ID, it won't be found.

2. Step 2: Check other options

   The selector should be cy.get('#submit button') reverses the selector incorrectly. You must use cy.find() instead of cy.get() is wrong because cy.get() is correct for global selection. The click() command is not supported on buttons is false; click() works on buttons.

3. Final Answer:

   The button does not have an ID 'submit' -> Option A

4. Quick Check:

   Selector must match element attributes [OK]

Hint: Verify element attributes match your selector exactly [OK]

Common Mistakes:

• Using wrong selector syntax
• Assuming click() doesn't work on buttons
• Confusing cy.get() with cy.find()

5. You want to select the second <li> element inside a <ul id='menu'>. Which cy.get() selector is correct?

hard

A. cy.get('ul#menu li[2]')

B. cy.get('#menu li:nth-child(2)')

C. cy.get('#menu li:eq(2)')

D. cy.get('ul#menu > li:nth-type(2)')

Solution

1. Step 1: Understand CSS nth-child selector

   li:nth-child(2) selects the second child <li> element inside its parent.

2. Step 2: Evaluate each option

   cy.get('ul#menu li[2]') uses invalid attribute selector. cy.get('#menu li:eq(2)') uses jQuery syntax not supported in CSS selectors. cy.get('ul#menu > li:nth-type(2)') uses invalid 'nth-type(2)' selector.

3. Final Answer:

   cy.get('#menu li:nth-child(2)') -> Option B

4. Quick Check:

   Use nth-child(n) to select nth element [OK]

Hint: Use :nth-child(n) to pick the nth child element [OK]

Common Mistakes:

• Using jQuery :eq() in CSS selectors
• Using attribute selectors incorrectly
• Confusing nth-child with nth-of-type
