easy

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

Testing Fundamentals
def test_addition():
    result = add(2, 3)
    assert result [1] 5
Drag options to blanks, or click blank then click option'
A==
B=
C!=
D<
Attempts:

💡 Hint
Common Mistakes
Using '=' instead of '==' in the assertion.

Complete the code to skip a test when a condition is met.

Testing Fundamentals
import pytest

@pytest.mark.skipif([1], reason="Not supported")
def test_feature():
    assert feature() == True
Drag options to blanks, or click blank then click option'
ATrue
BNone
CFalse
D0
Attempts:
3 left
💡 Hint
Common Mistakes
Using False which causes the test to run instead of skipping.

Fix the error in the assertion to properly check if a list contains an item.

Testing Fundamentals
def test_contains():
    items = ['apple', 'banana', 'cherry']
    assert [1] in items
Drag options to blanks, or click blank then click option'
Aitems
B'banana'
C'grape'
Dbanana

Fill both blanks to create a dictionary comprehension that maps words to their lengths only if length is greater than 3.

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 value instead of its length.
Using '<' instead of '>' in the condition.

Fill all three blanks to create a filtered dictionary with uppercase keys and values greater than 0.

Testing Fundamentals
result = [1]: [2] for [3], v in data.items() if v > 0}
Drag options to blanks, or click blank then click option'
Ak.upper()
Bv
Ck
Dvalue
Attempts:

💡 Hint
Common Mistakes
Using 'value' instead of 'v' for values.
Using 'value' or 'v' instead of 'k' for keys in the loop.

1. Why is good test design important in software testing?
easy
A. It increases the number of bugs in the software
B. It makes the software run faster
C. It saves time and effort by focusing on key test cases
D. It replaces the need for developers

Solution

  1. Step 1: Understand the purpose of test design

    Good test design aims to make testing efficient by selecting important test cases.
  2. Step 2: Identify the effect of good test design

    By focusing on key cases, it saves time and effort during testing.
  3. Final Answer:

    It saves time and effort by focusing on key test cases -> Option C
  4. Quick Check:

    Good test design = saves time and effort [OK]
Hint: Good test design focuses on important cases to save effort [OK]
Common Mistakes:
  • Thinking test design makes software run faster
  • Believing test design increases bugs
  • Confusing test design with developer roles
2. Which of the following is the correct way to write a test case title for clarity?
easy
A. Check stuff
B. Test login functionality with valid credentials
C. Bug fix test
D. Run test

Solution

  1. Step 1: Identify clarity in test case titles

    A clear test case title describes what is tested and under what condition.
  2. Step 2: Compare options for clarity

    Test login functionality with valid credentials clearly states the feature and condition; others are vague.
  3. Final Answer:

    Test login functionality with valid credentials -> Option B
  4. Quick Check:

    Clear test title = Test login functionality with valid credentials [OK]
Hint: Use descriptive titles that explain what is tested [OK]
Common Mistakes:
  • Using vague or generic titles
  • Not specifying conditions in test titles
  • Writing incomplete test case descriptions
3. Consider this test design approach: prioritizing tests that cover critical features first. What is the main benefit?
medium
A. It delays testing of critical features
B. It ensures all minor bugs are found before major ones
C. It increases the total number of tests needed
D. It helps find important bugs faster and saves testing time

Solution

  1. Step 1: Understand prioritizing critical features

    Testing critical features first targets the most important parts early.
  2. Step 2: Identify the benefit of this approach

    This helps find important bugs faster and reduces wasted time on less important tests.
  3. Final Answer:

    It helps find important bugs faster and saves testing time -> Option D
  4. Quick Check:

    Prioritizing critical tests = find bugs faster [OK]
Hint: Test critical features first to find major bugs quickly [OK]
Common Mistakes:
  • Thinking minor bugs are found before major ones
  • Assuming more tests always means better efficiency
  • Believing critical features are tested last
4. A tester wrote many test cases but they overlap and repeat steps unnecessarily. What is the main problem here?
medium
A. Test design is inefficient and wastes time
B. Test cases are too short
C. Test cases are missing assertions
D. Test cases are not automated

Solution

  1. Step 1: Analyze overlapping and repeated test steps

    Overlapping tests cause duplication and waste effort.
  2. Step 2: Identify the impact on efficiency

    This shows poor test design leading to inefficiency and wasted time.
  3. Final Answer:

    Test design is inefficient and wastes time -> Option A
  4. Quick Check:

    Overlapping tests = inefficient design [OK]
Hint: Avoid duplicate steps to keep tests efficient [OK]
Common Mistakes:
  • Confusing test length with efficiency
  • Ignoring missing assertions as the main issue
  • Assuming automation fixes design problems
5. You have a large feature with many possible inputs. How can good test design help you test efficiently?
hard
A. By selecting representative test cases that cover different input types
B. By testing every possible input combination regardless of time
C. By skipping tests for inputs that seem unlikely to fail
D. By writing one test case that covers all inputs at once

Solution

  1. Step 1: Understand the challenge of many inputs

    Testing every input is often impossible due to time limits.
  2. Step 2: Identify efficient test design strategy

    Choosing representative cases covers important variations without excess tests.
  3. Final Answer:

    By selecting representative test cases that cover different input types -> Option A
  4. Quick Check:

    Representative tests = efficient coverage [OK]
Hint: Pick key cases that represent input variety [OK]
Common Mistakes:
  • Trying to test all inputs exhaustively
  • Skipping tests based on guesswork
  • Using one test case for all inputs
