4. Which testing type verifies that different modules work together correctly?

Unit testing

Integration testing

Smoke testing

Performance testing

Integration testing verifies that different modules or components of a system interact correctly. It focuses on the interfaces and communication between modules, ensuring that they work together as intended. This type of testing helps identify issues that may arise when combining individual units, which might not be evident during unit testing.

5. What is the main goal of a smoke test in CI/CD?

Test every code line thoroughly

Verify basic functionality works after deployment

Check for memory leaks

Measure application response time

A smoke test in CI/CD aims to ensure that the most critical functions of an application work after a new deployment. It serves as a preliminary check to identify any major issues before proceeding with more detailed testing, allowing teams to catch significant problems early in the development process.

6. Which tool is commonly used for continuous integration and automated testing?

Jenkins

Notepad

Paint

Calculator

Jenkins is a widely used open-source automation server that facilitates continuous integration and continuous delivery (CI/CD). It allows developers to automate the building, testing, and deployment of software, ensuring that code changes are integrated smoothly and tested automatically, which enhances collaboration and efficiency in software development processes.

7. True or False: Manual testing is completely replaced by automated testing in CI/CD.

True

False

Manual testing remains essential in CI/CD because it addresses aspects that automation cannot, such as user experience, exploratory testing, and complex scenarios. While automated testing enhances efficiency and consistency, manual testing is crucial for validating functionality, usability, and overall quality, ensuring a comprehensive testing approach.

8. A____test checks that the application performs well under heavy user load.

A performance test evaluates how an application behaves under high user demand, ensuring it can handle increased traffic without compromising speed or functionality. This type of testing identifies potential bottlenecks and helps optimize the system for scalability and reliability, ultimately enhancing user experience during peak usage times.

9. Which statement about unit tests is true?

They test the entire application at once

They test individual functions or methods

They replace integration testing

They are run only after deployment

Unit tests focus on verifying the functionality of specific components, such as individual functions or methods, in isolation from the rest of the application. This allows developers to identify and fix bugs at a granular level, ensuring that each part of the code behaves as expected before integrating it with other components.

10. What does test automation improve in a CI/CD environment?

Developer salaries

Code feedback speed and release frequency

Hardware costs

Office productivity

Test automation enhances code feedback speed by allowing immediate testing after changes, enabling developers to identify issues quickly. This leads to faster iterations and more frequent releases, as automated tests can run continuously throughout the CI/CD pipeline, ensuring that code quality is maintained while accelerating the deployment process.
