02
Write test cases for live order tracking in a food delivery app.
Show answer
Verify each status change appears in order: placed, accepted, preparing, picked up and delivered. Check the rider's location updates on the map at the expected interval. Test the estimated time updates when there is a delay. Verify notifications for each status. Check behaviour when the network drops and recovers, when the app is reopened, and when the order is cancelled midway. Confirm tracking stops after delivery and the rating screen appears.
03
The UI shows the correct order total, but the database has a different value. What do you check?
Show answer
Note the order ID and compare the UI value, the API response and the database value to find where they differ. Check if the UI calculates the total on the screen instead of using the saved value, whether taxes, discounts or rounding are applied at different layers and whether a later update job changed the record. Log the bug with all three values, because invoices and reports will use the database figure.
04
Write a SQL query to find duplicate records.
Show answer
SELECT email, COUNT(*) FROM users GROUP BY email HAVING COUNT(*) > 1;
05
How do you plan testing for a two-week sprint?
Show answer
In sprint planning, review each story's acceptance criteria and estimate test effort, including test data and regression. Write test cases in the first days while development starts. Ask for early builds so testing is spread across the sprint, not crowded at the end. Keep time for regression and bug retesting in the last two or three days. Track progress on the board and raise risks in stand-up.
06
How do you set up and clean test data for database tests without affecting other testers?
Show answer
Create your own data with a clear prefix or tag, such as emails starting with qa_ravi_, or IDs in a reserved range. Insert data through the app or API where possible so it follows real rules, and keep SQL setup scripts in version control. After testing, delete only your tagged rows, or run inside a transaction and roll back. Never edit shared master data without telling the team.
07
What is a bug bash and how do you run one?
Show answer
A bug bash is a short, time-boxed session where people from across the team, including developers, product and support, test the product together to find as many issues as possible before a release. To run one, share a build, scope and test accounts, assign focus areas, give a simple bug template and a shared board, then triage findings at the end. It brings fresh eyes and finds usability issues formal tests miss.
08
What is a traceability matrix?
Show answer
A grid mapping requirements to test cases and defects, proving every requirement is tested.
09
Write test cases for a change password screen.
Show answer
1. Correct current password and valid new password: success, old password stops working. 2. Wrong current password: error, no change. 3. New password same as current: rejected if policy says so. 4. New and confirm fields do not match: error. 5. New password below minimum or above maximum length: error. 6. Missing digit or special character: policy message. 7. Other active sessions are logged out. 8. Confirmation email or alert is sent. 9. Password fields are masked.
10
What is the definition of done?
Show answer
A shared checklist for when a story is complete, usually including code review, tests passing, no open critical bugs and documentation updated.
11
A training portal is adding recorded video lessons and podcasts. What accessibility checks do you run?
Show answer
Check that prerecorded videos have accurate, synchronised captions, not just auto-generated ones with errors, and that audio-only content like podcasts has a transcript. Important visual information that is not spoken should have audio description or be covered in the transcript. Media should not autoplay with sound, and player controls must work by keyboard and be announced by screen readers. Also check that nothing flashes more than three times per second.
12
Difference between black box, white box and grey box testing?
Show answer
Black box tests behaviour without code knowledge; white box tests internal logic and paths; grey box uses partial knowledge of the internals.
13
What is regression testing, and when do you automate it?
Show answer
Re-testing existing features after a change. Automate stable, repetitive, high-value flows that run every release.
14
How do you test touch target size and gestures for accessibility in a mobile app?
Show answer
Check that buttons and icons are large enough to tap without hitting neighbours: Android guidance is 48 by 48 dp and iOS is 44 by 44 points. Test with large font settings and one-handed use. Any action using complex gestures, such as swipe to delete or pinch, must have a simple tap alternative. Then turn on TalkBack and VoiceOver and confirm each control can be focused, named and activated.
15
A manager says the app has 50,000 daily users, so the load test must run 50,000 virtual users at once. How do you respond?
Show answer
Explain that daily users are not concurrent users. Of 50,000 users a day, only a fraction are active at the same moment, and even they pause between actions because of think time. Use analytics to find the real peak concurrency and request rate, for example 1,500 concurrent users at peak hour, and model that with a safety margin. Running 50,000 users clicking at once tests a load that never happens and wastes effort.
16
What do you do in the test execution phase when a test fails?
Show answer
Re-run the test once to confirm the failure and rule out wrong data or environment issues. Capture evidence such as screenshots, logs and the build number. Check for an existing bug, then log a new one with clear steps and link it to the test case. Mark the test as failed, and mark dependent tests as blocked if they cannot run. After the fix, retest and run related regression.
17
What sensitive data checks do you do in API responses and logs?
Show answer
Check that responses return only needed fields, with no passwords, password hashes, full card numbers, full ID numbers or internal keys. Verify personal data is masked where required, for example only the last four digits of a phone number. Look at application and browser console logs for tokens or personal data. Check error responses do not expose stack traces, SQL or server versions. Raise any leak as a high-severity bug.
18
What do you check when testing an API in Postman?
Show answer
Status code, response body and schema, headers, response time, error messages for invalid input, authentication (401/403) and that data is saved in the database.
19
What is a bug triage meeting?
Show answer
A regular review where QA, development and product assess new bugs and decide severity, priority, owner and target release.
20
A dashboard shows pass or fail status only with red and green dots. What is the issue?
Show answer
This relies on colour alone to give information, which fails WCAG criterion 1.4.1. Users with red-green colour blindness, which affects a noticeable share of men, cannot tell the states apart, and screen readers announce nothing. Recommend adding text or icons such as a tick and a cross with labels like 'Passed' and 'Failed', and accessible names for the dots. Test with a colour blindness simulator in browser developer tools.
21
How do you test push notifications?
Show answer
Verify notifications arrive when the app is in foreground, background and closed. Check title, text, icon and that tapping opens the right screen with the correct data. Test with notifications disabled at OS level and inside app settings. Check behaviour after logout, reinstall and on multiple devices with the same account. Test grouping of many notifications, time-sensitive ones, and that no notification shows private data on the lock screen.
22
How do you test app permissions such as camera, location and contacts?
Show answer
Check that the app asks for permission only when the feature is used, with a clear reason. Test allow, deny, and deny with do not ask again. When denied, the app must not crash and should explain how to enable it in settings. Revoke permission from settings while the app is in background and return. Test allow only once or only while using the app options on newer OS versions.
23
What do testers look for during a requirement review?
Show answer
Check that each requirement is clear, complete, consistent and testable. Look for vague words like fast or user-friendly, missing error handling, undefined limits, conflicting rules and missing roles or states. For each requirement ask how you would test it and what the expected result is. Record questions in a review log and get answers from the business analyst before writing test cases, so ambiguity does not turn into defects later.
24
What is a Three Amigos session?
Show answer
Three Amigos is a short meeting where a business person or product owner, a developer and a tester discuss a story before development. The business explains the need, the developer considers how to build it and the tester asks what could go wrong and how it will be verified. The output is clear acceptance criteria and example scenarios. It prevents misunderstandings and reduces bugs found late.
25
Why do performance reports use percentiles like p90 and p95 instead of averages?
Show answer
An average hides slow requests. If 90 requests take 1 second and 10 take 10 seconds, the average is 1.9 seconds, which looks fine, but one user in ten waits 10 seconds. The p95 value means 95 percent of requests were faster than it, so it shows what most users actually experience, including the slow tail. Service level targets are usually written as percentiles, such as p95 under 2 seconds.
26
How do you do cross-browser testing and choose which browsers to cover?
Show answer
Use analytics to pick browsers and versions that most real users have, plus the ones listed in the requirement, usually the latest two versions of major desktop and mobile browsers. Run the main flows on each and check layout, fonts, forms, date pickers, file upload and JavaScript errors in the console. Use responsive mode for screen sizes, and real devices or a cloud device lab for mobile browsers.
27
How do you run a moderated usability test session?
Show answer
Define goals and three to five realistic tasks, such as 'Book a train ticket for next Friday'. Recruit participants who match real users. In the session, explain that you are testing the product, not them, ask them to think aloud, and avoid hinting even when they struggle. Record the screen with consent, note where they hesitate or fail, and finish with a short questionnaire. Then group findings by severity and frequency.
28
What is SQL and why do testers use it?
Show answer
A language to query databases. Testers use it to verify data saved by the application, prepare test data and check backend results.
29
A user updates their phone number in the app, but the old number still appears in reports. What do you check?
Show answer
First query the main users table to see whether the update was saved. If it was, check where the report reads from: a view, a reporting copy, a cache or a nightly ETL table. The report may simply be stale until the next refresh, which may be by design. If the main table still has the old value, check the API request, the update query and any errors in logs, then log a bug with both query results.
30
What does INVEST mean for user stories?
Show answer
INVEST is a checklist for good user stories: Independent, Negotiable, Valuable, Estimable, Small and Testable. For testers, testable is the most important: a story must have clear acceptance criteria so you can say pass or fail. Small stories are easier to test within a sprint. If a story fails INVEST, raise it in refinement rather than discovering the gaps during testing.
31
What are stubs and drivers?
Show answer
Both are temporary pieces of code used in integration testing when some modules are not ready. A stub replaces a called lower-level module and returns fixed responses, used in top-down testing; for example, a stub payment service that always returns success. A driver replaces a calling higher-level module and sends inputs to the module under test, used in bottom-up testing. In API testing, mock servers play the role of stubs.
32
What are severity and priority? Give examples.
Show answer
Severity is impact on the system; priority is urgency of the fix. A crash in a rare report is high severity, low priority; a spelling mistake in the logo is low severity, high priority.
33
What is a sprint planning meeting and what does QA contribute?
Show answer
The team selects stories for the sprint. QA helps estimate testing effort, clarifies acceptance criteria and flags dependencies and risks.
34
What is the role of a QA lead across the STLC?
Show answer
A QA lead reviews requirements and plans testing, including scope, estimates, resources and risks. They assign work, set standards for test cases and bug reports, and review test artefacts. During execution, they track progress, run triage and remove blockers. At the end, they give a clear release recommendation, prepare closure reports and drive lessons learned. They also mentor the team and improve the process over time.
35
What is a test scenario for the login functionality at a high level?
Show answer
Valid login, invalid login, forgot password, locked account and session handling are the main scenarios to cover.
36
What is network condition testing for mobile apps?
Show answer
It checks app behaviour on different networks: Wi-Fi, 4G, 5G, slow 2G or 3G, high latency, packet loss and no network. Also test switching between Wi-Fi and mobile data in the middle of an action, and airplane mode. The app should show loaders and clear offline messages, retry safely without duplicate actions and not freeze. Network throttling tools in developer options or proxy tools help simulate these conditions.
