Interview preparation for testers in Testing Fundamentals - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to print the result of a simple test assertion.

Testing Fundamentals

assert [1] == 5

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

A2 * 2

B2 + 3

C10 - 6

D3 + 1

Attempts:

💡 Hint

Common Mistakes

Choosing an expression that does not equal 5 causes assertion failure.

The expression 2 + 3 equals 5, so the assertion passes.

2fill in blank

medium

Complete the code to check if a list contains a specific element.

Testing Fundamentals

assert 'bug' [1] ['bug', 'test', 'fix']

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

💡 Hint

Common Mistakes

Using '==' compares the whole list, not membership.

The keyword in checks if an element is inside a list.

3fill in blank

hard

Fix the error in the test function definition.

Testing Fundamentals

def test_example():
    result = 10 / [1]
    assert result == 5

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

A2

B10

C5

D0

Attempts:

💡 Hint

Common Mistakes

Using 0 causes a ZeroDivisionError.

Dividing 10 by 2 gives 5, so the assertion passes. Dividing by 0 causes an error.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension filtering even numbers.

Testing Fundamentals

evens = {num: num[1]2 for num in range(1, 6) if num [2] 2 == 0}

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

B%

C//

D+

Attempts:

💡 Hint

Common Mistakes

Using '//' divides and floors, not squares.

Using '+' adds numbers, not squares.

The expression num**2 squares the number. The condition num % 2 == 0 filters even numbers.

5fill in blank

hard

Fill all three blanks to create a filtered dictionary with uppercase keys and positive values.

Testing Fundamentals

filtered = [1]: [2] for [3] in data.items() if [2] > 0

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

Ak.upper()

Bv

Ck, v

Ditems

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'items' as a loop variable causes errors.

Mixing keys and values incorrectly.

Keys are converted to uppercase with k.upper(). Values v are used and filtered to be positive. Loop variables are k, v for key and value.
