Question 1

What is the purpose of a test fixture in desktop application unit testing?

Accepted Answer

A consistent, known state set up before each test to ensure tests are independent and repeatable

Answer

A test fixture sets up prerequisite objects, database state, or file system conditions before each test runs and tears them down afterward, ensuring test isolation.

Question 2

What does mocking mean in the context of desktop application testing?

Accepted Answer

Replacing real dependencies with controlled fake objects to test a component in isolation

Answer

Mocks replace real dependencies (databases, APIs, file systems) with fake objects whose behavior is controlled by the test, allowing isolated unit testing.

Question 3

What is code coverage and why is it measured in desktop application testing?

Accepted Answer

The percentage of code lines/branches executed by tests, indicating test thoroughness

Answer

Code coverage metrics show which portions of code are exercised by tests, helping teams identify untested areas that may harbor hidden bugs.

Question 4

What is the purpose of stress testing a desktop application?

Accepted Answer

Determine the application's behavior and limits when subjected to extreme load or resource constraints

Answer

Stress testing pushes the application beyond normal operating limits to identify failure points, resource exhaustion, and recovery behavior under extreme conditions.

Question 5

What is a 'test plan' in desktop application quality assurance?

Accepted Answer

A document describing the testing scope, strategy, resources, schedule, and acceptance criteria

Answer

A test plan formalizes what will be tested, how it will be tested, who will test it, and what criteria define a passing release, guiding the entire QA effort.
