Testing Concepts for Development

What is the primary goal of unit testing?

• To validate that individual components of the software work as intended.

• To ensure the software is free of bugs in production.

• To improve the overall performance of the software.

• To document the software's architecture and design.

How does integration testing differ from unit testing?

• Integration testing is only performed on the database layer.

• Unit testing is done after integration testing.

• Integration testing focuses on performance metrics.

• Integration testing differs from unit testing in that it tests the interaction between components, while unit testing focuses on individual components.

What is the purpose of system testing in software development?

• To conduct performance testing under high load conditions.

• The purpose of system testing is to verify that the software system meets its specified requirements and functions correctly as a whole.

• To ensure the software is visually appealing and user-friendly.

• To evaluate the software's market competitiveness and pricing.

Define acceptance testing and its significance.

• Acceptance testing is crucial as it ensures that the software meets user requirements and is fit for use, thereby reducing the risk of defects and increasing user satisfaction.

• Acceptance testing is only for internal use by developers.

• Acceptance testing is a method to test hardware components only.

• Acceptance testing is performed after the software is released to the public.

What is regression testing and when is it performed?

• Regression testing is performed after code changes to ensure existing functionality remains unaffected.

• Regression testing is used to test the performance of the application under load.

• Regression testing is done before code changes to introduce new features.

• Regression testing is only performed for new software releases.

Explain the concept of performance testing.

• Performance testing assesses how a system performs under load, ensuring it meets speed and scalability requirements.

• Performance testing measures user satisfaction with a product.

• Performance testing focuses solely on security vulnerabilities.

• Performance testing is only concerned with user interface design.

What is the main focus of user testing?

• Assessing the technical performance of software

• Gathering demographic data from users

• Measuring the speed of application loading times

• Evaluating usability and user experience through real user interactions.

Describe the principles of test-driven development (TDD).

• Only testing after code is complete

• The principles of TDD include writing tests before code, ensuring tests fail initially, writing minimal code to pass tests, and refactoring while keeping tests passing.

• Writing code before tests

• Refactoring without running tests

What are the benefits of conducting unit tests?

• Increased code complexity

• Benefits of conducting unit tests include early bug detection, ensuring code correctness, facilitating refactoring, improving design, and serving as documentation.

• Higher maintenance costs

• Delayed deployment

How can integration testing help in identifying issues?

• Integration testing helps identify issues by verifying interactions between modules, ensuring they work together correctly.

• It eliminates the need for unit testing.

• It focuses solely on individual module performance.

• It helps in designing the user interface.
