Skills for modern testers in Testing Fundamentals - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a test case that checks if a function returns the expected result.

Testing Fundamentals

def test_addition():
    result = add(2, 3)
    assert result == [1]

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

💡 Hint

Common Mistakes

Using a wrong expected value in the assertion.

Forgetting to use assert to check the result.

The function add(2, 3) should return 5, so the assertion checks if result == 5.

2fill in blank

medium

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

Testing Fundamentals

def test_contains_element():
    items = ['apple', 'banana', 'cherry']
    assert [1] in items

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

A'melon'

B'orange'

C'grape'

D'banana'

Attempts:

💡 Hint

Common Mistakes

Checking for an element not present in the list.

Forgetting to put quotes around the string.

The list items contains 'banana', so the assertion checks if 'banana' is in the list.

3fill in blank

hard

Fix the error in the test function to correctly check if a number is even.

Testing Fundamentals

def test_is_even():
    number = 8
    assert number [1] 2 == 0

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

A%

B+

C-

D*

Attempts:

💡 Hint

Common Mistakes

Using addition or multiplication instead of modulo.

Checking equality incorrectly.

The modulo operator % returns the remainder. If number % 2 == 0, the number is even.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps words to their lengths for words longer than 3 characters.

Testing Fundamentals

lengths = {word: [1] for word in words if len(word) [2] 3}

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

Alen(word)

B<=

C>

Dword

Attempts:

3 left

💡 Hint

Common Mistakes

Using the word itself as the value instead of its length.

Using the wrong comparison operator.

The dictionary comprehension maps each word to its length using len(word). The condition filters words with length greater than 3 using len(word) > 3.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps uppercase keys to their values for items with positive values.

Testing Fundamentals

result = [1]: [2] for k, v in data.items() if v [3] 0

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

Ak.upper()

Bv

C>

Dk

Attempts:

3 left

💡 Hint

Common Mistakes

Using the original key instead of uppercase.

Using wrong comparison operator or filtering condition.

The comprehension uses k.upper() as keys, v as values, and filters items where v > 0.

Practice

1. Which skill is most important for a modern tester to communicate effectively with developers and stakeholders?

easy

A. Graphic design skills

B. Ability to write complex code

C. Physical endurance

D. Good communication skills

Solution

1. Step 1: Understand the role of communication in testing

   Testers must explain bugs and test results clearly to developers and stakeholders.

2. Step 2: Identify the skill that supports this role

   Good communication skills enable clear, effective sharing of information.

3. Final Answer:

   Good communication skills -> Option D

4. Quick Check:

   Communication = C [OK]

Hint: Think about talking and writing clearly [OK]

Common Mistakes:

• Confusing technical coding skills with communication
• Choosing unrelated skills like graphic design
• Ignoring the importance of clear explanations

2. Which of the following is the correct way to describe automation testing?

easy

A. Manually checking each feature every time

B. Using scripts to run tests automatically

C. Ignoring test cases to save time

D. Writing test cases only after release

Solution

1. Step 1: Define automation testing

   Automation testing uses scripts or tools to run tests without manual effort.

2. Step 2: Match the correct description

   Using scripts to run tests automatically fits this definition.

3. Final Answer:

   Using scripts to run tests automatically -> Option B

4. Quick Check:

   Automation = A [OK]

Hint: Automation means using scripts, not manual work [OK]

Common Mistakes:

• Confusing manual testing with automation
• Thinking automation means skipping tests
• Believing tests are written only after release

3. Consider this Python snippet used by a tester to check if a bug is fixed:

def is_bug_fixed(status):
    return status == "fixed"

result = is_bug_fixed("Fixed")
print(result)

What will be the output?

medium

A. True

B. Error

C. False

D. fixed

Solution

1. Step 1: Analyze the function comparison

   The function checks if status equals the string "fixed" exactly (case-sensitive).

2. Step 2: Check the input value

   The input is "Fixed" with uppercase F, which does not match "fixed" lowercase.

3. Final Answer:

   False -> Option C

4. Quick Check:

   Case-sensitive comparison = False [OK]

Hint: Remember string comparisons are case-sensitive [OK]

Common Mistakes:

• Ignoring case sensitivity in string comparison
• Expecting the function to return the input string
• Assuming no output or error

4. A tester wrote this code to check if a number is positive:

def check_positive(num):
    if num > 0:
        return True
    else
        return False

What is the error in this code?

medium

A. Missing colon after else

B. Wrong comparison operator

C. Function missing return statement

D. Indentation error on if statement

Solution

1. Step 1: Check syntax of if-else statements

   Python requires a colon (:) after else to mark the block start.

2. Step 2: Identify the missing colon

   The else line lacks the colon, causing a syntax error.

3. Final Answer:

   Missing colon after else -> Option A

4. Quick Check:

   Syntax requires colon after else [OK]

Hint: Look for missing colons after if/else [OK]

Common Mistakes:

• Thinking comparison operator is wrong
• Assuming return statements are missing
• Ignoring syntax errors like missing colons

5. A modern tester wants to improve test coverage by automating tests but also needs to adapt quickly to frequent changes in requirements. Which combination of skills best supports this goal?

hard

A. Automation skills and adaptability

B. Manual testing and strict process adherence

C. Graphic design and communication

D. Physical endurance and documentation

Solution

1. Step 1: Identify skills needed for automation

   Automation skills help create scripts to run tests faster and more often.

2. Step 2: Recognize the need for adaptability

   Adaptability allows testers to adjust tests quickly when requirements change.

3. Final Answer:

   Automation skills and adaptability -> Option A

4. Quick Check:

   Automation + Adaptability = A [OK]

Hint: Combine automation with flexibility for changing projects [OK]

Common Mistakes:

• Choosing manual testing only
• Ignoring adaptability in fast-changing projects
• Selecting unrelated skills like graphic design
