Parameterized tests in Selenium Python - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to import the parameterized decorator from the correct module.

Selenium Python

from [1] import parameterized

class TestLogin:
    @parameterized.expand([
        ("user1", "pass1"),
        ("user2", "pass2")
    ])
    def test_login(self, username, password):
        pass

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

💡 Hint

Common Mistakes

Importing parameterized from unittest or selenium instead of the parameterized module.

The parameterized decorator is imported from the parameterized module to enable parameterized tests.

2fill in blank

medium

Complete the code to use the parameterized decorator to run the test with multiple username and password pairs.

Selenium Python

@parameterized.expand([
    ("user1", "pass1"),
    ("user2", [1])
])
def test_login(self, username, password):
    pass

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

A"pass3"

B"password"

C"pass2"

D"1234"

💡 Hint

Common Mistakes

Using a password not matching the test data pairs.

The second tuple should have the password "pass2" to match the example pairs for parameterized testing.

3fill in blank

hard

Fix the error in the test method signature to accept parameters from the parameterized decorator.

Selenium Python

@parameterized.expand([
    ("user1", "pass1"),
    ("user2", "pass2")
])
def test_login(self, [1]):
    pass

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

Ausername, password

Buser, pass

Cself

Dargs

💡 Hint

Common Mistakes

Using only one parameter or incorrect parameter names.

The test method must accept the parameters username and password to receive the values from the parameterized decorator.

4fill in blank

hard

Fill both blanks to assert the page title after login using parameterized username and password.

Selenium Python

def test_login(self, username, password):
    self.driver.get("http://example.com/login")
    self.driver.find_element_by_id("username").send_keys(username)
    self.driver.find_element_by_id("password").send_keys(password)
    self.driver.find_element_by_id("submit").click()
    assert self.driver.title [1] [2]

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

A==

B"Dashboard"

C"Home"

D!=

💡 Hint

Common Mistakes

Using wrong comparison operators or incorrect expected title strings.

The assertion checks if the page title equals "Dashboard" after login.

5fill in blank

hard

Fill all three blanks to create a parameterized test that checks login with multiple credentials and asserts the welcome message.

Selenium Python

from parameterized import parameterized

class TestLogin:
    @parameterized.expand([
        ("user1", "pass1", [1]),
        ("user2", "pass2", [2])
    ])
    def test_login(self, username, password, expected_message):
        self.driver.get("http://example.com/login")
        self.driver.find_element_by_id("username").send_keys(username)
        self.driver.find_element_by_id("password").send_keys(password)
        self.driver.find_element_by_id("submit").click()
        message = self.driver.find_element_by_id("welcome").text
        assert message == [3]

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

A"Welcome user1!"

B"Welcome user2!"

Cexpected_message

D"Welcome!"

💡 Hint

Common Mistakes

Using string literals directly in the assertion instead of the expected_message variable.

The test uses parameterized tuples with expected welcome messages. The assertion compares the actual message to the expected_message parameter.
