💡 Hint

Common Mistakes

Using 'contain' instead of 'include' causes assertion failure.

Using 'includes' is not a valid Cypress assertion method.

The include method checks if a string contains a substring in Cypress BDD assertions.

3fill in blank

💡 Hint

Common Mistakes

Omitting parentheses causes syntax errors.

Using capitalized 'Of' is incorrect.

The correct syntax is length(5) with parentheses to call the method.

4fill in blank

hard

Fill both blanks to assert that the variable is a string and equals 'test'.

Cypress

expect(variable).to.be.a([1]).and.[2]('test');

💡 Hint

Common Mistakes

Using 'equals' instead of 'equal' causes errors.

Using 'str' instead of 'string' for type check is invalid.

Use a('string') to check type and equal('test') to check value equality.

5fill in blank

hard

Fill all three blanks to assert that the object has a property 'name' with value 'Alice' and is not null.

Cypress

expect(obj).to.have.property([1], [2]).and.to.not.be.[3];

Using undefined instead of null for the last blank.

Omitting quotes around property name or value.

The property method checks for a property and its value. Use not.be.null to assert the object is not null.
