Authentication testing in Testing Fundamentals - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to check if the login function returns True for valid credentials.

Testing Fundamentals

assert login('user1', 'password123') == [1]

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

ATrue

BFalse

CNone

D0

Attempts:

3 left

💡 Hint

Common Mistakes

Using False instead of True for successful login

Checking for None which means no return value

The login function should return True when the credentials are correct, so the assertion checks for that.

2fill in blank

medium

Complete the code to test that the login function raises an exception for empty username.

Testing Fundamentals

with pytest.raises([1]):
    login('', 'password123')

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

AKeyError

BValueError

CTypeError

DIndexError

Attempts:

3 left

💡 Hint

Common Mistakes

Using KeyError which is for missing dictionary keys

Using TypeError which is for wrong data types

The login function should raise a ValueError when the username is empty, indicating invalid input.

3fill in blank

hard

Fix the error in the test that checks login failure with wrong password.

Testing Fundamentals

assert login('user1', [1]) == False

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

A'password123'

BNone

C'wrongpass'

D''

Attempts:

3 left

💡 Hint

Common Mistakes

Using the correct password which makes the test pass incorrectly

Using None which might cause exceptions

The test should use a wrong password like 'wrongpass' to check that login fails and returns False.

4fill in blank

hard

Fill both blanks to create a test that checks if the login function rejects SQL injection attempts.

Testing Fundamentals

assert login([1], [2]) == False

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

A'admin' OR '1'='1'

B'password123'

C' OR '1'='1'

D'admin'

Attempts:

3 left

💡 Hint

Common Mistakes

Putting the injection string as username instead of password

Using correct credentials which makes the test pass incorrectly

The username is 'admin' and the password is an SQL injection string ' OR '1'='1'. The test checks that login rejects this attack and returns False.

5fill in blank

hard

Fill all three blanks to create a test that verifies the lockout after 3 failed login attempts.

Testing Fundamentals

for _ in range([1]):
    assert login('user2', [2]) == False
assert login('user2', [3]) == 'locked'

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

A3

B'wrongpass'

C'password123'

D'locked'

Attempts:

3 left

💡 Hint

Common Mistakes

Using the correct password which makes the test pass incorrectly

Using wrong number of attempts in the loop

The test tries to login 3 times with a wrong password 'wrongpass' and expects failure. Then it tries again and expects the account to be 'locked'.
