What is regression testing?

Regression testing verifies that changes in the software do not negatively impact existing functionality.

Explain the concept of test-driven development (TDD).

TDD involves writing tests before writing the actual code, promoting a more reliable and well-tested codebase.

What is the purpose of test automation?

Test automation aims to execute test cases automatically, saving time and resources, and providing quick feedback.

What are the advantages of manual testing?

Manual testing allows exploratory testing, human intuition, and is suitable for small-scale projects or when test cases change frequently.

What are the advantages of automated testing?

Automated testing provides faster execution, repeatability, and coverage of a large number of test cases.

Explain the concept of black-box testing.

Black-box testing focuses on testing the functionality of a system without knowledge of its internal code.

What is white-box testing?

White-box testing involves testing the internal logic, code structure, and flow of the software.

What is a test case?

A test case is a set of conditions or variables under which a tester will determine whether an application or software system works correctly.

What is the purpose of a test script?

A test script is a set of instructions written in a programming language to perform a specific test case.

What is the difference between smoke testing and sanity testing?

Smoke testing ensures the basic functionality works, while sanity testing verifies specific functionalities after changes or bug fixes.

Explain the concept of load testing.

Load testing assesses how a system performs under a specific load, ensuring it can handle anticipated user activity.

What is the difference between stress testing and load testing?

Stress testing evaluates how a system performs under extreme conditions, while load testing assesses performance under expected conditions.

What is the purpose of performance testing?

Performance testing ensures a system meets specified performance criteria and identifies bottlenecks and areas for improvement.

What is usability testing?

Usability testing assesses how user-friendly a system is by evaluating user interactions and user satisfaction.

What is the purpose of security testing?

Security testing identifies vulnerabilities and weaknesses in a system to ensure data and resources are protected.

Explain the concept of acceptance testing.

Acceptance testing validates whether a system meets specified business requirements and is ready for deployment.

What is the difference between manual and automated acceptance testing?

Manual acceptance testing is performed by humans, while automated acceptance testing is executed using tools and scripts.

What is exploratory testing?

Exploratory testing involves simultaneously designing and executing test cases, allowing testers to explore the software.

What is the role of a test environment?

A test environment provides the necessary hardware, software, and network configurations for testing.

What is the purpose of a defect report?

A defect report documents information about a defect or issue found during testing, facilitating communication with developers for resolution.

Explain the concept of code coverage.

Code coverage measures the percentage of code executed by tests, helping assess the thoroughness of test cases.

What is the difference between static and dynamic testing?

Static testing involves reviewing documents and code without execution, while dynamic testing involves executing code to identify defects.

What is a test harness?

A test harness is a set of tools, libraries, and software used to execute test cases and collect results.

Explain the concept of a test oracle.

A test oracle is a mechanism used to determine whether the output of a test case is correct.

What is the role of a test manager?

A test manager is responsible for planning, organizing, and leading the testing effort, including resource management and reporting.

What is the V-Model in software testing?

The V-Model is a testing model that correlates testing phases with development phases in a V-shaped manner.

What is the Agile testing methodology?

Agile testing is an iterative testing approach aligned with Agile development methodologies, emphasizing collaboration and flexibility.

Explain the concept of continuous testing.

Continuous testing integrates testing activities into the software development process, ensuring ongoing validation of code changes.

What is the purpose of a test repository?

A test repository stores and organizes test artifacts, including test cases, scripts, and results.

What is the significance of a traceability matrix in testing?

A traceability matrix maps requirements to test cases, ensuring comprehensive test coverage.

What is the difference between alpha and beta testing?

Alpha testing is performed by the internal development team, while beta testing involves real users testing the software in a real-world environment.

What is mutation testing?

Mutation testing involves introducing small changes (mutations) to the code to assess the effectiveness of the test suite in detecting these changes.

Explain the concept of non-functional testing.

Non-functional testing assesses aspects such as performance, usability, security, and scalability, focusing on the system’s behavior under specific conditions.

What is the role of a test lead?

A test lead is responsible for leading a testing team, coordinating test activities, and ensuring the successful execution of the testing process.

What is the difference between alpha and beta testing?

Alpha testing is performed by the internal development team, while beta testing involves real users testing the software in a real-world environment.

What is the importance of a test strategy document?

A test strategy document outlines the testing approach, objectives, and resources for a testing project.

Explain the concept of data-driven testing.

Data-driven testing involves executing test cases with multiple sets of input data to ensure comprehensive coverage.

What is the significance of a test log?

A test log records information about test execution, including test case status, defects found, and other relevant details.

What is the role of a test automation architect?

A test automation architect designs and implements test automation frameworks, ensuring efficient and maintainable test automation.

Explain the concept of API testing.

API testing involves testing the application programming interfaces to ensure proper functionality, security, and performance.

What is the purpose of a test summary report?

A test summary report provides a summary of testing activities, including test results, metrics, and recommendations.

What is risk-based testing?

Risk-based testing prioritizes testing efforts based on the identified risks, focusing on areas with higher potential impact.

Explain the concept of model-based testing.
