02
What is a REST API?
Show answer
An API style using HTTP methods on resources identified by URLs, usually exchanging JSON and staying stateless.
03
How do you convert existing manual test cases into automated scripts?
Show answer
Pick a small set of stable, high-value regression cases first. Review each one: make steps precise, remove judgement-based checks and define clear expected results. Prepare test data that the script can create and clean up. Build reusable page objects and helpers for common steps like login. Automate, run several times to confirm stability, then link each script to its manual case ID and mark the manual case as automated.
04
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.
05
Why should we hire you as a manual tester over someone with more automation experience?
Show answer
Answer with strengths and honesty. For example: I am strong at understanding requirements, designing test cases with techniques like boundary values and finding bugs through exploratory testing, which automation depends on to be useful. I also write SQL and test APIs in Postman. I am learning Playwright and have automated a few smoke tests, so I can grow into automation while adding value from the first week.
06
What is localisation and internationalisation testing?
Show answer
Internationalisation tests that the product can support many languages and formats; localisation tests that a specific locale is correct for text, currency, date and layout.
07
What is a sprint retrospective?
Show answer
A team meeting at the end of a sprint to discuss what went well, what did not and what to improve next.
08
The build arrived three days late but the release date has not moved. How do you prioritise execution?
Show answer
Rank test cases by business risk and usage: critical flows like login, payment and data saving first, then new features, then high-risk regression from past defects, and cosmetic checks last. Run smoke testing immediately to avoid wasting time on a broken build. Share the reduced plan with the lead and product owner so they know what will not be covered, and get agreement on the remaining risk.
09
What are the seven principles of testing?
Show answer
Testing shows presence of defects, exhaustive testing is impossible, test early, defects cluster, the pesticide paradox, testing is context-dependent and absence-of-errors is a fallacy.
10
What is the difference between a build and a release?
Show answer
A build is a compiled version of the software created from the latest code, often many times a day, and given to QA for testing. A release is a tested, approved version delivered to customers or production, usually with release notes and a version number. Many builds can go through testing before one of them is promoted as a release. Testers always note the build number in bug reports.
11
What is the difference between a walkthrough and an inspection?
Show answer
Both are static review techniques. A walkthrough is informal and led by the author, who explains the document or code to peers to share knowledge and gather feedback. An inspection is the most formal review: it has defined roles such as moderator, reader and scribe, uses checklists, needs preparation and records defects and metrics. Inspections find more defects but take more effort.
12
What are implicit waits, explicit waits and auto-waiting?
Show answer
An implicit wait, in Selenium, sets a global time the driver keeps retrying to find any element before failing. An explicit wait waits for a specific condition, such as an element being clickable or a spinner disappearing, and is more precise. Auto-waiting, built into Playwright and Cypress, automatically waits for elements to be visible, enabled and stable before acting. Mixing implicit and explicit waits in Selenium can cause unpredictable delays.
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
Write test cases for a shopping cart.
Show answer
Add, remove, update quantity, price and tax calculation, coupon codes, stock limits, cart persistence after login and checkout navigation.
15
Write test cases for a file upload feature.
Show answer
Allowed and disallowed formats, size limits, empty file, duplicate names, special-character names, cancel upload, slow network and multiple files.
16
What is data-driven testing?
Show answer
Data-driven testing runs the same test steps many times with different input and expected values taken from a table, CSV, JSON or spreadsheet. For example, one login test can run with valid users, locked users, wrong passwords and blank fields. It reuses the logic, makes adding cases easy and maps well to equivalence partitioning and boundary values from manual design. Tools support it through parameterised tests, such as pytest.mark.parametrize.
17
Describe a time you missed a bug that reached production.
Show answer
Model answer: Situation: a discount was applied twice when users pressed the pay button quickly. Task: I had tested the feature and missed it. Action: I owned it in the retrospective, helped reproduce and verify the fix, and added double-click and slow network cases to our checklist for all payment buttons. Result: similar issues were caught in later sprints, and I learned to always test repeated actions.
18
What is CSRF and how is it prevented?
Show answer
Cross-site request forgery tricks a logged-in user's browser into sending an unwanted request to a site, such as changing their email, because the browser automatically includes cookies. Prevention includes anti-CSRF tokens in forms, SameSite cookie settings and re-authentication for sensitive actions. Testers check that state-changing requests fail when the token is missing or reused, and that such actions are not done through GET requests.
19
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.
20
What is shift-left testing and why is it cheaper?
Show answer
Shift-left means starting testing activities earlier in the life cycle: reviewing requirements, joining design discussions and writing tests before code is complete. A defect found in requirements may cost a short conversation to fix, while the same defect found in production may need a hotfix, data correction and customer support. Testers shift left by asking questions in grooming, defining acceptance criteria and reviewing designs.
21
SQL: find duplicate emails.
Show answer
SELECT email, COUNT(*)
FROM users
GROUP BY email
HAVING COUNT(*) > 1;
22
What is the difference between a known issue and an open bug at release time?
Show answer
An open bug is any defect not yet resolved. A known issue is an open bug that the team has consciously agreed to release with, after assessing its impact, and has documented in release notes or support notes, often with a workaround. Every known issue is an open bug, but not every open bug should ship. QA makes sure known issues are listed and approved by the product owner.
23
Tell me about a time you started learning automation while working as a manual tester.
Show answer
Situation: our regression took three days every release. Task: I wanted to help but knew only manual testing. Action: I spent an hour daily learning Python and Playwright, automated the login and search smoke cases first and asked a developer to review my code each week. Result: in two months my scripts ran in CI on every build, saving about a day per release, and I moved into a hybrid QA role.
24
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.
25
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.
26
Tell me about a time exploratory testing helped you find a critical bug.
Show answer
Model answer: Situation: a new leave management module had passed all scripted cases. Task: I had a one-hour exploratory session. Action: I applied leave, then changed my manager in the profile while the request was pending. Result: the request disappeared for both managers and could never be approved. It was fixed before release, and the team added role-change scenarios to the regression suite.
27
What is a performance baseline?
Show answer
A performance baseline is a set of measurements of the current system under a known load, such as response times, throughput, error rate and resource usage. Every new build or release is compared with it to spot regressions. For example, if the checkout API had p95 of 800 milliseconds at 200 users last release and now shows 1.5 seconds, the change needs investigation. A benchmark compares against an industry or competitor standard.
28
SQL: find orders that have no matching customer record.
Show answer
-- orphan orders indicate a broken foreign key or bad data load
SELECT o.order_id, o.customer_id
FROM orders o
LEFT JOIN customers c ON c.customer_id = o.customer_id
WHERE c.customer_id IS NULL;
29
How do you test a mobile app when the device storage is almost full?
Show answer
Fill the device storage close to the limit, then install or update the app and confirm a clear message if it cannot proceed. Inside the app, try downloads, photo capture, caching and saving drafts. The app should show a helpful error, not crash or corrupt data. Also check what happens to the local database when a write fails, and whether the app recovers after space is freed.
30
How do you use JIRA in testing?
Show answer
Log and track bugs, link them to stories, build dashboards and filters with JQL, manage sprints and generate reports.
31
What is the difference between alpha and beta testing?
Show answer
Alpha is done in-house by internal teams before release; beta is done by a limited group of real users in their own environment.
32
What are the typical JIRA workflows for bugs?
Show answer
Statuses like To Do, In Progress, In Review, Ready for QA, Done and Reopened, with transitions that depend on the team's configuration.
33
What is a workload model in performance testing?
Show answer
A workload model describes the realistic load to simulate: which user journeys run, their mix in percentages, the number of concurrent users, request rates, think times, data volumes and the ramp-up pattern. For example, 60 percent browse, 25 percent search, 10 percent add to cart and 5 percent checkout at a peak of 2,000 concurrent users. It is built from production analytics and business forecasts, and wrong models produce meaningless results.
34
How do you test an API using Postman?
Show answer
Create a request with method, URL, headers and body, send it, check status and body, add test scripts and save it in a collection.
35
Write a pytest test using requests that checks a GET call returns 200 and a non-empty list.
Show answer
import requests
BASE_URL = 'https://qa-api.example.com'
def test_get_products_returns_list():
response = requests.get(f'{BASE_URL}/products', timeout=10)
assert response.status_code == 200
body = response.json()
assert isinstance(body, list)
assert len(body) > 0
assert 'id' in body[0]
36
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.
