💡 Hint

Common Mistakes

Using be which checks object identity, not value equality.

Using have or include which are for collections.

The eq matcher checks if the value is equal to the expected value.

2fill in blank

medium

Ruby

expect(numbers).to [1] 5

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

💡 Hint

Common Mistakes

Using eq which checks for exact equality, not inclusion.

Using contain which is not a valid RSpec matcher.

The include matcher checks if a collection contains a specific element.

3fill in blank

hard

Fix the error in the code to check if the string message starts with 'Hello'.

Ruby

💡 Hint

Common Mistakes

Using eq which checks full equality.

Using include which checks for substring anywhere.

Using match which expects a regex.

The start_with matcher checks if a string begins with the given substring.

4fill in blank

hard

Fill both blanks to check if the variable value is greater than 5 and less than 10.

Ruby

expect(value).to be [1] 5.and be [2] 10

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

B<

C==

D>=

💡 Hint

Common Mistakes

Using equality operators instead of comparison.

Reversing the comparison signs.

The be > matcher checks if the value is greater than 5, and be < checks if it is less than 10.

5fill in blank

hard

Fill all three blanks to check if the hash user has a key :name with value 'Alice' and the key :age is greater than 20.

Ruby

expect(user). [1] include([2] => 'Alice'}) and expect(user[:age]).to be [3] 20

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

B:name

C>

💡 Hint

Common Mistakes

Using have_key instead of include for key-value pairs.

Using wrong comparison operators for age.

Use to with include to check the key-value pair, and be > to check the age.
