QUESTION 43
Which of the following best describes code refactoring?

Adding new features

Fixing bugs

Changing code structure without affecting behavior

QUESTION 44
A Python script is crashing randomly. The team uses the logging module with custom formats and severity levels. They identify repeated IndexError incidents logged at the ERROR level.
Which strategies are most likely helping them trace the issue?

Custom log format with timestamps

Assertion tracking

Log file rotation

Severity-based filtering

Error trace capturing

QUESTION 45
Which testing level focuses primarily on verifying interactions between integrated units or modules?

System testing

Unit testing

Acceptance testing

Integration testing

QUESTION 46
In the test pyramid, which layer typically contains the largest number of tests?

Manual UI tests

Unit tests

End-to-end tests

Performance tests

QUESTION 47
What is the typical first phase in a structured software testing process?

Test execution

Test closure

Test planning

Defect reporting

QUESTION 48
Which are valid types of test coverage metrics?

Branch coverage

Variable coverage

Path coverage

Module documentation coverage

QUESTION 49
Which of the following best defines regression testing?

QUESTION 55
A developer encounters an unexpected error in a Python function. They use pdb, inspect variables, set breakpoints, and finally resolve the issue by modifying a loop condition.
Which debugging steps were likely involved?

Trace stack analysis

Logging with info-level severity

Step into function calls

Conditional breakpoint setting

Output assertion validation

QUESTION 56
Which of the following activities typically occur during the test execution phase?

Logging defects
