Practice - 5 Tasks

1fill in blank

easy

Complete the code to print the test progress percentage.

Testing Fundamentals

total_tests = 50
completed_tests = 20
progress = (completed_tests [1] total_tests) * 100
print(f"Progress: {progress}%")

💡 Hint

Common Mistakes

Using multiplication instead of division causes wrong progress calculation.

Adding or subtracting numbers instead of dividing.

To calculate progress percentage, divide completed tests by total tests.

2fill in blank

medium

Complete the code to update the progress bar width based on test progress.

Testing Fundamentals

progress_percent = 75
progress_bar_style = f"width: [1]%"
print(progress_bar_style)

💡 Hint

Common Mistakes

Using variables that do not represent percentage causes wrong style.

Forgetting to include the percent sign in the style string.

The variable progress_percent holds the current progress value to set the width.

Fix the error in the code that calculates and prints test progress.

Testing Fundamentals

total = 40
completed = 10
progress = completed [1] total * 100
print(f"Test progress: {progress}%")

💡 Hint

Common Mistakes

Using multiplication instead of division.

Using addition or subtraction which gives wrong results.

Division is needed to get the fraction of tests completed before multiplying by 100.

4fill in blank

hard

Fill both blanks to create a dictionary showing test names and their pass status.

Testing Fundamentals

tests = ['login', 'signup', 'checkout']
results = [True, False, True]
status = {tests[1]: results[2] for i in range(len(tests))}
print(status)

💡 Hint

Common Mistakes

Using parentheses instead of square brackets causes errors.

Mixing up the index variable or forgetting brackets.

Use square brackets to access list elements by index.

5fill in blank

hard

Fill all three blanks to filter tests that passed and create a summary dictionary.

Testing Fundamentals

tests = ['login', 'signup', 'checkout', 'profile']
results = [True, False, True, False]
summary = {tests[1]: results[2] for i in range(len(tests)) if results[i][3]
print(summary)

💡 Hint

Common Mistakes

Using parentheses instead of square brackets for list access.

Forgetting to compare result to True in the if condition.

Use square brackets to access list items and filter where result is True.

Practice

1. What does test progress reporting mainly show during software testing?

easy

A. How many tests have been completed and how many are left

B. The total number of bugs found in the software

C. The time taken to write each test case

D. The number of developers working on the project

Solution

1. Step 1: Understand the purpose of test progress reporting

   Test progress reporting is designed to show the current status of testing, specifically how many tests are done and how many remain.

2. Step 2: Compare options with the definition

   Only How many tests have been completed and how many are left correctly describes this purpose. Other options describe different metrics unrelated to progress reporting.

3. Final Answer:

   How many tests have been completed and how many are left -> Option A

4. Quick Check:

   Progress reporting = tests done vs remaining [OK]

Hint: Focus on tests done and left to find progress [OK]

Common Mistakes:

• Confusing bug count with progress
• Thinking progress shows developer count
• Mixing test writing time with progress

2. Which of the following is the correct way to represent test progress as a percentage?

easy

A. (Total tests / Number of tests completed) * 100

B. (Number of tests completed / Total tests) * 100

C. (Number of tests remaining / Number of tests completed) * 100

D. (Number of tests completed - Number of tests remaining) * 100

Solution

1. Step 1: Recall the formula for percentage progress

   Progress percentage is calculated by dividing completed tests by total tests, then multiplying by 100.

2. Step 2: Evaluate each option

   (Number of tests completed / Total tests) * 100 matches the correct formula. Options B, C, and D use incorrect divisions or operations.

3. Final Answer:

   (Number of tests completed / Total tests) * 100 -> Option B

4. Quick Check:

   Progress % = completed ÷ total x 100 [OK]

Hint: Divide completed by total, then multiply by 100 [OK]

Common Mistakes:

• Reversing numerator and denominator
• Using subtraction instead of division
• Multiplying before dividing

3. Consider this code snippet updating test progress:

total_tests = 50
completed_tests = 20
progress = (completed_tests / total_tests) * 100
print(f"Progress: {progress}%")

What will be the printed output?

medium

A. Progress: 25.0%

B. Progress: 20.0%

C. Progress: 50.0%

D. Progress: 40.0%

Solution

1. Step 1: Calculate the progress value

   progress = (20 / 50) * 100 = 0.4 * 100 = 40.0

2. Step 2: Check the printed output

   The print statement outputs "Progress: 40.0%" exactly.

3. Final Answer:

   Progress: 40.0% -> Option D

4. Quick Check:

   20 ÷ 50 x 100 = 40.0 [OK]

Hint: Divide completed by total, multiply by 100 for percent [OK]

Common Mistakes:

• Misreading completed and total values
• Confusing 20/50 as 25%
• Ignoring multiplication by 100

4. A tester wrote this code to show test progress:

total_tests = 100
completed_tests = 30
progress = completed_tests / total_tests * 100
print("Progress: " + progress + "%")

What is the error in this code?

medium

A. Division by zero error

B. Incorrect formula for progress

C. Cannot concatenate string and float directly

D. Missing parentheses in print statement

Solution

1. Step 1: Identify the data types in the print statement

   progress is a float, and the code tries to concatenate it directly with strings using +.

2. Step 2: Understand Python string concatenation rules

   Python cannot concatenate string and float directly; progress must be converted to string first.

3. Final Answer:

   Cannot concatenate string and float directly -> Option C

4. Quick Check:

   String + float needs conversion [OK]

Hint: Convert numbers to string before concatenation [OK]

Common Mistakes:

• Assuming division by zero
• Thinking formula is wrong
• Ignoring type errors in print

5. You want to create a test progress report that updates after each test and shows both fraction and percentage. Which approach is best?

hard

A. After each test, print: "Completed X/Y tests (Z%)" where Z = (X/Y)*100

B. Print total tests once, then print completed tests separately without percentage

C. Only print percentage after all tests finish

D. Print completed tests count only, no total or percentage

Solution

1. Step 1: Understand the goal of progress reporting

   It should show how many tests are done, total tests, and progress percentage updated continuously.

2. Step 2: Evaluate each option for completeness and clarity

   After each test, print: "Completed X/Y tests (Z%)" where Z = (X/Y)*100 shows fraction and percentage after each test, which is clear and informative. Other options miss key info or delay updates.

3. Final Answer:

   After each test, print: "Completed X/Y tests (Z%)" where Z = (X/Y)*100 -> Option A

4. Quick Check:

   Show fraction and percent continuously [OK]

Hint: Show fraction and percent after each test for clarity [OK]

Common Mistakes:

• Not updating progress continuously
• Omitting total tests count
• Showing only percentage or only count
