Common Mistakes

Choosing options that ignore or delay defect handling.

Code reviews help catch defects early, which is a key defect prevention technique.

Fix the error in the code that applies defect prevention by using a checklist.

Testing Fundamentals

def apply_defect_prevention():
    checklist = ['requirements', 'design', 'code']
    for item in checklist:
        if item == '[1]':
            print('Check completed')

💡 Hint

Common Mistakes

Using a word not in the checklist for the condition.

The checklist includes 'code', so the condition should check for 'code' to print the message.

4fill in blank

Fill both blanks to complete the defect prevention code that logs defects and notifies the team.

Testing Fundamentals

def log_and_notify(defect):
    log = []
    log.append([1])
    if [2]:
        notify_team(defect)

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

Bdefect.severity == 'high'

Cdefect.severity != 'low'

Ddefect.id

💡 Hint

Common Mistakes

Using incorrect comparison operators or logging wrong defect attributes.

The defect description is logged, and the team is notified only if severity equals 'high'.

5fill in blank

hard

Fill all three blanks to create a defect prevention function that filters defects by type and counts them.

Testing Fundamentals

def count_defects(defects):
    filtered = [d for d in defects if d.type == [1]]
    count = len(filtered)
    return [2] + [3]

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

A'UI'

Bcount

C0

D'backend'

💡 Hint

Common Mistakes

Using wrong defect types or incorrect return expressions.

The function filters defects of type 'UI', counts them, and returns the count plus zero (no offset).
