1. What is the difference between functional and non-
functional testing?
Functional testing checks if the software works as per requirements (e.g., login
functionality). Non-functional testing evaluates performance, usability, and
scalability (e.g., how fast the login page loads). For example, functional testing
ensures a button works, while non-functional testing ensures it responds quickly
under heavy traffic.
2. How do you prioritize test cases?
I prioritize test cases based on risk, business impact, and frequency of use. Critical
functionalities like payment processing are tested first, followed by less critical
features. For example, in an e-commerce app, I’d test checkout before testing
product reviews.
3. Explain a bug lifecycle.
A bug lifecycle starts with identifying and reporting a defect. It then goes through
stages like review, fixing, retesting, and closure. For example, if a login button fails, I
log it, developers fix it, I retest it, and once verified, the bug is closed.
4. What is regression testing, and when do you perform it?
Regression testing ensures new code changes don’t break existing functionality. I
perform it after every release or bug fix. For example, after updating a search
feature, I retest the entire search module to ensure no side effects.
5. How do you handle tight deadlines in testing?
I focus on risk-based testing, prioritizing critical functionalities first. I also
communicate with the team to adjust scope or timelines. For example, if a release is
due, I test core features like login and payment, leaving less critical features for
later.
6. What tools have you used for test automation?
I’ve used tools like Selenium for web automation, Appium for mobile, and Postman
for API testing. For example, I automated login functionality using Selenium to save
time during regression testing.
, 7. How do you ensure good communication with
developers?
I maintain clear, concise bug reports with steps to reproduce, expected vs. actual
results, and screenshots. For example, if a button isn’t working, I provide a detailed
description and a video if needed.
8. What is the difference between smoke and sanity
testing?
Smoke testing checks if the build is stable enough for further testing, while sanity
testing verifies specific functionality after minor changes. For example, smoke
testing ensures the app launches, while sanity testing checks if a new feature works
as expected.
9. How do you approach testing in an Agile environment?
I collaborate closely with developers and product owners, participate in daily stand-
ups, and test iteratively. For example, I test user stories as soon as they’re
developed, ensuring quick feedback and faster releases.
10. What is your approach to testing a new feature?
I start by understanding requirements, writing test cases, and performing functional,
boundary, and negative testing. For example, for a new search feature, I test valid
inputs, invalid inputs, and edge cases like special characters.
These answers are concise, easy to understand, and can be tailored further based on
your experience.
