Frequently Asked Questions
What is the difference between functional and non-functional testing?
Functional testing verifies that the software functions as intended and meets specified requirements, while non-functional testing assesses aspects like performance, usability, and reliability.
Can you explain the software testing life cycle (STLC)?
The STLC consists of several phases including requirement analysis, test planning, test case development, test environment setup, test execution, defect reporting, and test closure.
What are some common types of software testing?
Common types include unit testing, integration testing, system testing, acceptance testing, regression testing, and performance testing.
How do you prioritize testing tasks?
Prioritization is based on factors such as risk assessment, functionality criticality, customer requirements, and the impact on users. High-risk areas and frequently used features are typically tested first.
What is a test case, and what are its components?
A test case is a set of conditions under which a tester will determine whether a system or software application is working correctly. Key components include test case ID, description, preconditions, test steps, expected results, and actual results.
What is the difference between a bug, defect, and error?
An error is a mistake made by a developer, a defect is a flaw in the software that causes it to produce incorrect results, and a bug is a defect that needs to be fixed.
What tools do you use for automated testing?
Common tools include Selenium, QTP, JUnit, TestNG, and Cucumber, depending on the application and testing requirements.
How do you handle test data management?
Test data management involves creating, maintaining, and using data for testing. It can include using production data, synthetic data generation, and data masking to ensure privacy.
What is continuous testing, and why is it important?
Continuous testing is the practice of executing tests as part of the software delivery pipeline. It ensures that testing occurs throughout the development lifecycle, providing immediate feedback to developers and improving software quality.
How do you ensure that your testing is thorough?
Thorough testing can be ensured by creating comprehensive test plans, performing risk analysis, using various testing techniques, and continuously reviewing and updating test cases based on new features and changes.
