Practice - 5 Tasks

1fill in blank

easy

Complete the code to name a test function that pytest will discover automatically.

PyTest

def [1]():
    assert 1 + 1 == 2

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

💡 Hint

Common Mistakes

Naming the function without 'test_' prefix

Using camel case starting with uppercase

Pytest discovers test functions that start with test_. So test_addition is correct.

2fill in blank

medium

Complete the code to name a test file that pytest will discover automatically.

PyTest

# File name: [1]

def test_example():
    assert True

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

Aexample_test.py

BTestExample.py

Ctest_example.py

Dexample.py

💡 Hint

Common Mistakes

Naming file without 'test_' prefix or '_test' suffix

Using uppercase letters in file name

Pytest discovers test files that start with test_ or end with _test.py. Here, test_example.py is correct.

3fill in blank

hard

Fix the error in the test class name so pytest will discover its test methods.

PyTest

class [1]:
    def test_method(self):
        assert True

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

💡 Hint

Common Mistakes

Class name not starting with 'Test'

Using lowercase class names

Pytest discovers test classes that start with Test and do not have an __init__ method. So TestMyClass is correct.

4fill in blank

hard

Fill both blanks to create a test function that pytest will discover and run.

PyTest

def [1]([2]):
    assert [2] > 0

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

Atest_positive

Bvalue

Ccheck_positive

Dnum

💡 Hint

Common Mistakes

Function name not starting with 'test_'

Using invalid parameter names

The function name must start with test_ and the parameter can be any valid name, here value is used.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that filters test data for pytest.

PyTest

filtered = { [1]: [2] for [1] in data if [2] [3] 10 }

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

Akey

Bvalue

C>

D<

💡 Hint

Common Mistakes

Using same variable name for key and value

Wrong comparison operator

The comprehension uses key and value as variable names, and filters values greater than 10 using >.
