02
The test environment is down for two days just before release. What do you do?
Show answer
Escalate immediately with the impact on the schedule. While it is down, prepare test data, review and update test cases, and test what you can elsewhere: API tests against another environment, UI on a developer machine or a staging copy. Track the lost hours in the status report. When the environment returns, run smoke first, then the prioritised list, and ask whether the release date or scope needs to change.
03
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.
04
What is cold start versus warm start, and why test app launch time?
Show answer
A cold start launches the app from scratch when it is not in memory, loading the process and the first screen; it is the slowest. A warm start happens when the app process exists but the screen must be recreated, and a hot start just brings it to the foreground. Users abandon slow apps, so teams set targets, such as cold start under two seconds on a mid-range device, and measure each release for regressions.
05
How do you handle pressure when many bugs are found close to a release?
Show answer
Model answer: Situation: two days before a release, we found 15 new bugs in checkout. Task: help the team decide what to fix. Action: I stayed calm, retested each one quickly, ranked them by user impact, and shared a clear list in triage with must-fix and can-wait items. Result: we fixed five critical bugs, released on time with documented known issues, and no critical issue reached users.
06
SQL: count today's orders by status.
Show answer
SELECT status, COUNT(*) AS total
FROM orders
WHERE created_at >= CURRENT_DATE
AND created_at < CURRENT_DATE + INTERVAL '1 day'
GROUP BY status
ORDER BY total DESC;
07
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.
08
How do you write steps to reproduce for a bug that needs specific test data?
Show answer
Start with preconditions: environment, build number, user role and the exact data state, such as an account with two pending orders and zero wallet balance. Mention how to create the data or give the test account ID. Then list numbered steps with exact inputs and finish with expected and actual results. If the data is hard to set up, attach the SQL used or a database screenshot so the developer can recreate it quickly.
09
Write a SQL query to find duplicate records.
Show answer
SELECT email, COUNT(*) FROM users GROUP BY email HAVING COUNT(*) > 1;
10
What is the difference between vulnerability scanning and penetration testing?
Show answer
Vulnerability scanning uses automated tools to look for known weaknesses, such as outdated libraries, missing security headers or open ports. It is fast, repeatable and can run in the pipeline, but gives false positives. Penetration testing is a deeper, mostly manual exercise by security experts who try to exploit weaknesses and chain them like a real attacker. Teams scan regularly and run penetration tests before major releases or yearly.
11
What is decision table testing?
Show answer
List conditions and actions in a table and cover every combination of conditions (rules) — ideal for business rules like loan approval: salary > X AND credit score > Y → approve.
12
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.
13
How do you test a web page with a screen reader?
Show answer
Turn on the screen reader, for example NVDA with a browser, and listen rather than look. Navigate by headings to check the structure is logical, by landmarks to find main regions and by Tab through controls. Each control should announce a clear name, role and state, such as 'Subscribe, checkbox, not checked'. Check images, form errors, dynamic updates like cart counts and dialogs. Note exactly what was announced in bug reports.
14
An automated test keeps failing because an element's ID is generated differently on every build. What do you do?
Show answer
Stop using the dynamic ID. Look for a stable alternative: the element's role and visible name, its label, a stable attribute, or a relative locator based on a nearby fixed element. The best long-term fix is asking developers to add a data-testid attribute. Avoid partial matches on random strings, which can break again. Then update the locator in the page object so every test using it is fixed at once.
15
A screen reader announces 'button, button, button' on a toolbar. What is the bug and how do you report it?
Show answer
The toolbar uses icon-only buttons without accessible names, so users hear the role but not the purpose. Report it with the page, the screen reader and browser versions, the exact announcement and the expected one, such as 'Bold, toggle button, not pressed'. Reference WCAG 4.1.2 Name, Role, Value. The fix is an aria-label or visually hidden text on each button, plus a tooltip that also helps sighted users.
16
SQL: find duplicate emails.
Show answer
SELECT email, COUNT(*)
FROM users
GROUP BY email
HAVING COUNT(*) > 1;
17
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.
18
What are test data and how do you prepare them?
Show answer
The inputs used in tests. Prepare using valid, invalid and boundary values from production-like but masked data, spreadsheets or generators.
19
A security scan says your login page can be loaded inside a frame on other sites. What is the risk and how do you confirm it?
Show answer
Clickjacking tricks a user into clicking something on your site while it is hidden inside a frame on an attacker's page, for example a hidden Transfer button under a fake Play button. A tester checks whether sensitive pages can be loaded in an iframe on another site, and inspects response headers for Content-Security-Policy frame-ancestors or X-Frame-Options set to DENY or SAMEORIGIN. If the page loads in the frame, log it.
20
What is CI/CD and how does testing fit?
Show answer
Code is built and tested automatically on each change; tests are quality gates that stop faulty builds from moving forward.
21
A developer changed a shared header component used on every page. What testing do you plan?
Show answer
Retest the change itself, then run a focused regression on every page type that uses the header: home, listing, detail, checkout and account. Check navigation links, search, login and logout state, cart count and the mobile menu. Do cross-browser and responsive checks because layout changes affect all sizes. A quick visual comparison against the previous build helps spot alignment issues across many pages.
22
What new success criteria in WCAG 2.2 should testers know?
Show answer
WCAG 2.2, published in 2023, added criteria including Focus Not Obscured, so sticky headers must not hide the focused element; Dragging Movements, which needs a non-drag alternative; Target Size Minimum of 24 by 24 CSS pixels; Consistent Help placement; Redundant Entry, so users are not asked for the same information twice; and Accessible Authentication, which avoids memory puzzles at login. It also removed the old Parsing criterion.
23
SQL: find customers who placed more than three orders in the last 30 days.
Show answer
SELECT c.id, c.name, COUNT(o.id) AS order_count
FROM customers c
JOIN orders o ON o.customer_id = c.id
WHERE o.order_date >= CURRENT_DATE - INTERVAL '30' DAY
GROUP BY c.id, c.name
HAVING COUNT(o.id) > 3
ORDER BY order_count DESC;
24
What is the OWASP Top 10 and why should testers know it?
Show answer
The OWASP Top 10 is a widely used list of the most critical web application security risks, published by an open community project. It includes broken access control, cryptographic failures, injection, insecure design, security misconfiguration, vulnerable components and authentication failures. Testers use it as a checklist to include basic security checks in their testing and to speak the same language as security teams.
25
What does the absence-of-errors fallacy mean?
Show answer
It means that finding and fixing many defects does not guarantee success if the system itself does not meet user needs. A bug-free product built on wrong or misunderstood requirements is still a failure. For example, a perfectly working report that shows the wrong business metric is useless to the client. This is why testers validate against real user expectations, not just the written specification.
26
What is the difference between authentication and authorization?
Show answer
Authentication checks who you are, for example by password, OTP or biometrics. Authorization checks what you are allowed to do after you are identified, such as whether you can view reports or delete users. Authentication comes first. Testers check authentication with wrong credentials and expired sessions, and authorization by trying actions with a lower-privilege account or by calling restricted URLs and APIs directly.
27
What are suspension and resumption criteria in a test plan?
Show answer
Suspension criteria define when testing should be paused because continuing would waste effort, for example when a blocker bug stops the main flow, the build fails smoke testing or the environment is down. Resumption criteria define what must happen to restart, such as a new build that passes smoke testing or the environment restored. Writing these down avoids arguments and shows clearly why testing time was lost.
28
How do you test API error handling for invalid input?
Show answer
Send requests with missing required fields, wrong data types, values beyond limits, invalid formats such as a bad email, unknown fields and an empty or malformed JSON body. The API should return a 4xx code such as 400 or 422, a clear error message that names the field, and no stack trace or database details. Also check that nothing was partly saved in the database after the failed request.
29
Write a CSS selector and an XPath for a Login button that has the attribute data-testid='login-btn' and the text Login.
Show answer
/* CSS selector using the test id */
button[data-testid='login-btn']
// XPath using the test id
//button[@data-testid='login-btn']
// XPath using the visible text
//button[normalize-space()='Login']
30
Tell me about a time you organised or ran a bug bash before a release.
Show answer
Situation: a new seller onboarding flow was due in a week and only two testers had seen it. Task: I wanted wider coverage quickly. Action: I set up a one-hour bug bash with developers, product and support, shared test accounts, focus areas and a simple bug form, then triaged findings with the lead. Result: we found 18 issues, including two blockers on low-end phones, and fixed them before launch.
31
How do you plan testing for a feature that depends on a third-party service?
Show answer
Identify the integration points and the service's sandbox, limits and test data. Plan to test with a mock or stub early for our logic and error handling, then against the real sandbox for integration. Include failure scenarios: timeout, slow responses, invalid data and the service being down. Add the dependency to the risk list, with contacts and a fallback plan, and confirm production credentials and monitoring before go-live.
32
What are common HTTP status codes?
Show answer
200 OK, 201 Created, 204 No Content, 400 Bad Request, 401 Unauthorized, 403 Forbidden, 404 Not Found, 500 Internal Server Error.
33
You change the order ID in a URL and see another customer's order. What is this and what do you do?
Show answer
This is an insecure direct object reference, a form of broken access control and a critical security bug, because any user can read other users' data. Stop exploring further beyond what is needed to confirm it, record the request, accounts used and evidence, and log it as a critical bug with restricted visibility. Inform the lead and security contact immediately. The fix is a server-side ownership check on every request.
34
How do you decide which automated tests run on every pull request and which run nightly?
Show answer
Pull request checks must be fast, usually under ten to fifteen minutes, and highly reliable, so they include unit tests, API tests for changed services and a small UI smoke set of critical flows. The full UI regression, cross-browser runs, long data-driven suites and performance checks run nightly or before release. Tag tests by suite, measure run times and flakiness, and move tests between suites based on value and speed.
35
What is test automation and what problems does it solve?
Show answer
Test automation means using scripts and tools to run tests, compare results and report them without a person doing each step. It solves slow and repetitive regression, gives fast feedback on every code change in CI, runs the same checks exactly the same way every time and covers many data combinations. It does not replace thinking: exploratory testing, usability judgement and new feature testing still need manual testers.
36
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]
37
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.
38
Write test cases for a signup form.
Show answer
Mandatory fields, email format, password rules, duplicate email, terms checkbox, captcha, confirmation email and field length limits.
39
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.
40
What is defect density?
Show answer
The number of defects per size of software, for example defects per thousand lines of code or per module, used to compare quality.
