What is the primary goal of quality engineering in software development?
✔✔ The primary goal of quality engineering in software development is to ensure that the final
product meets the required quality standards and functions correctly in real-world scenarios,
thereby enhancing customer satisfaction.
Explain the concept of test-driven development (TDD).
✔✔ Test-driven development (TDD) is a software development approach where tests are written
before the actual code. Developers write a failing test case first, then write the minimum code
necessary to pass the test, followed by refactoring the code to improve quality.
What is the significance of automation in quality engineering?
✔✔ Automation in quality engineering increases efficiency by reducing the time and effort
required for repetitive testing tasks, improves accuracy by minimizing human error, and allows
for more frequent testing cycles, enabling quicker feedback on product quality.
Describe the role of continuous integration (CI) in the software development lifecycle.
1
,✔✔ Continuous integration (CI) involves regularly integrating code changes into a shared
repository, where automated builds and tests are run. This practice helps identify defects early,
improves collaboration among team members, and accelerates the development process.
What is the purpose of regression testing?
✔✔ Regression testing aims to verify that recent code changes have not adversely affected
existing functionality. It ensures that previously working features continue to perform as
expected after updates or enhancements.
How can exploratory testing complement automated testing?
✔✔ Exploratory testing allows testers to use their intuition and experience to explore the
application without predefined test cases, identifying issues that automated tests might miss. It
complements automated testing by adding a layer of human insight and creativity to the quality
assurance process.
What are the key principles of the Agile testing mindset?
✔✔ The key principles of the Agile testing mindset include collaboration between developers
and testers, iterative testing throughout the development cycle, adaptability to change, and a
focus on delivering working software frequently.
2
,Explain the difference between functional and non-functional testing.
✔✔ Functional testing evaluates whether the software functions as intended and meets specified
requirements, while non-functional testing assesses aspects such as performance, usability,
reliability, and security, focusing on how the software behaves under various conditions.
What is a test case, and what are its essential components?
✔✔ A test case is a set of conditions or variables under which a tester determines whether an
application or system is functioning correctly. Essential components include a unique identifier,
test description, preconditions, test steps, expected results, and postconditions.
How do you prioritize test cases in a testing strategy?
✔✔ Test cases can be prioritized based on factors such as risk assessment, the criticality of
features, user impact, and historical defect data. High-priority test cases are typically those that
cover core functionalities or areas that have been problematic in the past.
What is the purpose of performance testing, and how is it conducted?
✔✔ Performance testing evaluates how a system behaves under various workloads to determine
its responsiveness, stability, and scalability. It is conducted by simulating multiple users and
transactions using tools that measure metrics such as response time, throughput, and resource
utilization.
3
, How can a quality engineer ensure effective communication within a development team?
✔✔ A quality engineer can ensure effective communication by fostering a collaborative
environment, actively participating in meetings, utilizing collaboration tools for transparency,
and encouraging open discussions about testing challenges and findings.
What are the characteristics of a good defect report?
✔✔ A good defect report is clear, concise, and contains essential information such as a unique
identifier, description of the issue, steps to reproduce, severity level, expected vs. actual results,
and any relevant screenshots or logs.
Describe the role of metrics in quality engineering.
✔✔ Metrics play a crucial role in quality engineering by providing quantitative data that helps
assess the effectiveness of testing efforts, track progress, identify trends, and inform decision-
making regarding process improvements and resource allocation.
What is the importance of user acceptance testing (UAT)?
✔✔ User acceptance testing (UAT) is vital as it involves real users validating the software
against their requirements and expectations. It ensures that the final product is fit for use and
meets the business needs before it is deployed to the production environment.
