Key elements in a defect report

Which of the following is NOT a key element to include in a clear defect report?

A Expected and actual results

B Tester’s personal opinion about the developer

C Environment details like browser or OS version

D Steps to reproduce the defect

💡 Hint

Think about what information helps fix the defect, not personal feelings.

A good defect report focuses on facts and clear information to help developers reproduce and fix the issue. Personal opinions do not help and should be avoided.

Correct assertion for defect severity

You want to write an assertion to check if a defect's severity is set to 'Critical'. Which assertion is correct?

Testing Fundamentals

defect = {'id': 101, 'severity': 'Critical'}

# Choose the correct assertion below:

A assert defect.get('severity') == 'Critical'

B assert defect['severity'] == 'critical'

C assert defect['severity'] = 'Critical'

D assert defect['severity'] != 'Critical'

💡 Hint

Remember Python is case-sensitive and assignment '=' is not used in assertions.

Option A correctly uses the get method and matches the exact case 'Critical'. Option A fails due to case mismatch. Option A uses assignment instead of comparison. Option A asserts the opposite.

Identify the error in defect report code

What error will this defect report submission code raise?

Testing Fundamentals

def submit_defect(defect):
    if defect['title'] and defect['description']:
        print('Defect submitted')
    else:
        print('Missing information')

submit_defect({'title': 'Crash', 'description': 'App crashes on start'})

A TypeError because defect is not a dictionary

B KeyError because 'title' key is missing

C SyntaxError due to missing colon after else

D No error, prints 'Defect submitted'

💡 Hint

Check the syntax of if-else statements carefully.

The else statement is missing a colon at the end, causing a SyntaxError.

Best practice for defect tracking tool usage

Which practice is best when using a defect tracking tool?

A Update defect status promptly and add comments when progress is made

B Only update defect status at the end of the testing cycle

C Create multiple duplicate defect entries for the same issue to get faster attention

D Assign defects randomly without considering expertise

💡 Hint

Think about clear communication and avoiding confusion.

Updating defect status promptly and adding comments helps everyone stay informed and speeds up resolution. Creating duplicates causes confusion. Delayed updates reduce transparency. Random assignment wastes resources.

Output of defect report filtering code

What is the output of this Python code that filters defects by priority?

Testing Fundamentals

defects = [
    {'id': 1, 'priority': 'High'},
    {'id': 2, 'priority': 'Low'},
    {'id': 3, 'priority': 'Medium'},
    {'id': 4, 'priority': 'High'}
]

high_priority_ids = [d['id'] for d in defects if d['priority'] == 'High']
print(high_priority_ids)

A [2, 3]

B []

C [1, 2, 3, 4]

D [1, 4]

💡 Hint

Look for defects where priority equals 'High'.

The list comprehension selects defects with priority 'High', which are ids 1 and 4.
