01
findElement vs findElements?
Show answer
findElement returns the first match and throws NoSuchElementException if nothing is found. findElements returns a List (empty if nothing is found) — handy to check whether an element exists.

02
Which reporting tools do you use?
Show answer
TestNG reports, ExtentReports and Allure give charts, screenshots and logs that are easy to share with the team.
03
What are generics in Java and how do they help in a test framework?
Show answer
Generics let classes and methods work with a type parameter while keeping compile-time type safety, such as List<String> or a method <T> T readJson(String path, Class<T> type). In a framework they let you write one reusable helper for many types, for example a generic API client that deserializes responses into any POJO, or a BasePage method that returns the correct page type for chaining. They remove casts and catch type errors at compile time.
04
Nightly Jenkins regression runs take 4 hours. How would you bring it down?
Show answer
Measure first: find the slowest tests and setup steps. Then run tests in parallel across Grid nodes or containers, replace UI setup with API calls, remove duplicate coverage, move checks down to API level, split the suite into shards across agents, and cache Maven dependencies. Aim for a smoke stage under 15 minutes on every commit and a parallel regression under an hour.
05
What can testers do with Chrome DevTools Protocol support in Selenium 4?
Show answer
Selenium 4 exposes CDP through the DevTools interface and the newer cross-browser BiDi APIs. Testers can capture console logs and JavaScript errors, intercept or mock network requests, emulate slow networks or geolocation, add basic authentication headers and collect performance metrics. CDP is Chromium-specific and tied to browser versions, so for long-term code prefer WebDriver BiDi features where available, and keep CDP usage behind a small helper class.
06
What is the difference between @BeforeTest and @BeforeMethod?
Show answer
@BeforeTest runs once before all methods in a test tag of testng.xml; @BeforeMethod runs before every test method.
07
Write a Java stream that extracts and sorts product prices from a list of WebElements.
Show answer
List<Double> prices = driver.findElements(By.cssSelector(".price"))
.stream()
.map(WebElement::getText)
.map(t -> t.replaceAll("[^0-9.]", ""))
.map(Double::parseDouble)
.sorted()
.collect(Collectors.toList());
System.out.println(prices);
08
What are the standalone, hub and node, and distributed modes of Selenium Grid 4?
Show answer
Standalone runs every Grid component and a local node in a single process, which suits a laptop or a single container. Hub and node mode runs the router, distributor, queue and session map together as the hub, with separate node processes registering to it, which is the usual team setup. Fully distributed mode runs each component separately, often on Kubernetes, for very large grids that need independent scaling and high availability.
09
How do you validate a JSON response in REST Assured?
Show answer
Use then().statusCode(200).body("data.id", equalTo(5)), or extract() the response and assert fields with JsonPath.
10
Tell me about a time your API tests caught a breaking change before the UI tests did.
Show answer
Situation: a backend team renamed a response field during a refactor. Task: our nightly REST Assured suite had to protect the mobile and web clients. Action: schema validation failed within minutes of the merge, and I shared the failing response and the contract with the developer. Result: the field was restored with a deprecation plan before the UI suite even ran, and the team added our schema tests to their pull request checks.
11
What are Java 8 streams and lambdas?
Show answer
Lambdas are short anonymous functions; streams process collections declaratively with filter, map and collect, for example filtering link text from a list of elements.
12
Write a Dockerfile that runs a Maven and TestNG test suite.
Show answer
FROM maven:3.9-eclipse-temurin-21
WORKDIR /app
# cache dependencies first for faster rebuilds
COPY pom.xml .
RUN mvn -q dependency:go-offline
COPY src ./src
COPY testng.xml .
ENV GRID_URL=http://selenium-hub:4444
CMD ["sh", "-c", "mvn test -Dgrid.url=$GRID_URL -Dsurefire.suiteXmlFiles=testng.xml"]
13
Your recorded JMeter script fails with 403 on every request after login. What is the likely cause?
Show answer
The script is probably replaying hard-coded dynamic values, such as a CSRF token, session cookie or auth header captured during recording. The server rejects them because they belong to the old session. Add an HTTP Cookie Manager so cookies are handled per thread, extract the CSRF or bearer token from the login response with an extractor, and replace the recorded value with the variable. Verify with View Results Tree on one thread.
14
PageFactory with @FindBy or By locators: which do you prefer and why?
Show answer
Many teams now prefer plain By locators with explicit waits. PageFactory proxies look up elements lazily, which can hide timing problems and makes StaleElementReference harder to reason about, and its AjaxElementLocatorFactory waits are less flexible. PageFactory is fine and readable for stable pages. The key is consistency across the framework and always waiting for the right condition before acting.
15
Tell me about a time you worked with a team in a different location or time zone on automation.
Show answer
Situation: our developers were in another time zone and test failures waited a day for replies. Task: reduce delays. Action: I wrote clear failure reports with screenshots, logs and steps, recorded short videos for complex issues, and set a fixed 30-minute overlap call twice a week. Result: turnaround on defects dropped from two days to about one, and fewer issues bounced back.
16
Tell me about a time a CI pipeline you owned broke right before a release.
Show answer
Situation: the night before release, every UI test failed in Jenkins. Task: find the cause fast and unblock the release. Action: I checked the console and saw a browser and driver version mismatch after an agent update, pinned the browser image version, reran the suite and shared a short note. Result: the release went out on time and we added image version pinning to the pipeline.
17
An API test passes alone but fails when the suite runs in parallel. What could be wrong?
Show answer
Likely shared state. Common causes are static RestAssured settings changed by one test, shared test data like the same user being updated by two tests, token reuse after another test logged out, or rate limits. Fix by using per-test RequestSpecification instead of global statics, creating unique data per test, isolating tokens, and checking server rate-limit responses such as 429.
18
Your retry analyzer makes the suite green but bugs are slipping into production. What is wrong?
Show answer
Retries are hiding real intermittent defects, such as race conditions, by treating them as flaky tests. Limit retries to one, report retried tests separately as flaky in the dashboard, and require a ticket for each one. Review retried tests weekly to find whether the cause is the test or the product. Retries should buy time to fix, not replace fixing.
19
Why do Selenium browser containers need a larger shm_size?
Show answer
Chrome and Firefox use shared memory at /dev/shm for rendering and inter-process communication. Docker gives containers only 64 MB of shared memory by default, which is not enough for modern pages, so the browser tab crashes with errors like session deleted because of page crash. Setting shm_size to 2g in Compose, or --shm-size=2g with docker run, fixes it. Mounting /dev/shm from the host is an alternative.
20
What is the difference between an array and an ArrayList?
Show answer
Arrays have a fixed size and can hold primitives; ArrayList grows dynamically, holds objects and offers helper methods.
21
What is OAuth 2.0 in API testing?
Show answer
An authorisation framework where a client obtains an access token from an auth server and sends it as a Bearer token; tests fetch and reuse the token in setup.
22
What is BDD and how does Cucumber work?
Show answer
Behaviour-driven development writes scenarios in Given-When-Then Gherkin that map to step definitions in code, so business and QA share one language.
23
You need 2,000 UI tests to run on every pull request in under 20 minutes. How would you design the infrastructure?
Show answer
First shrink the UI suite by moving checks to API and unit level. Then run the rest on an autoscaling Grid, for example Kubernetes with KEDA, sized so tests divided by slots times average duration fits the budget. Make tests independent with API-based setup and ThreadLocal drivers. Shard tests across CI agents, fail fast on smoke tests first, and track flaky tests separately. Pin image versions and monitor queue time.
24
Write Appium code to scroll to an element by its text using UiScrollable on Android.
Show answer
// Scrolls the first scrollable container until the text is visible
String selector = "new UiScrollable(new UiSelector().scrollable(true))"
+ ".scrollIntoView(new UiSelector().text(\"Order History\"))";
WebElement item = driver.findElement(AppiumBy.androidUIAutomator(selector));
item.click();
25
How do you take a screenshot on failure in TestNG?
Show answer
Implement ITestListener.onTestFailure():
File src = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
then copy it into the reports folder.
26
An API returns 200 but your REST Assured assertion on a field fails with a null value. How do you debug it?
Show answer
Log the full response with then().log().all() to see the actual body. Common causes are a wrong JSON path, such as missing a wrapper like data, the field being in an array needing an index, a different content type like XML or HTML error page, or the field name having different case. Fix the path, and add a schema check so structure changes are caught clearly.
27
What is the Maven Surefire plugin and how do you configure it for TestNG?
Show answer
Surefire runs tests during the test phase. For TestNG, configure suiteXmlFiles with the path to testng.xml, so mvn test runs that suite. You can pass system properties, set parallel and threadCount, and control reports. Make the suite file a property like ${suiteXml} so CI can choose smoke.xml or regression.xml with -DsuiteXml=smoke.xml.
28
What are relative locators in Selenium 4?
Show answer
Locators such as above, below, toLeftOf and near that find elements by their position relative to another element.
29
What locator strategy do you follow inside page objects?
Show answer
Prefer stable attributes in this order: dedicated test attributes like data-testid, id, name, then short CSS selectors, and XPath only when text or complex relationships are needed. Avoid absolute XPaths and index-based locators. Keep locators as private final By fields at the top of the class with clear names, so updates are quick and readable.
30
How do you retry failed tests in TestNG?
Show answer
Implement IRetryAnalyzer with a retry count and attach it through the test annotation or a listener to rerun flaky tests.
31
How do you handle dynamic elements whose ids change?
Show answer
Use CSS or XPath with contains(), starts-with() or stable attributes, relative axes, or data-test attributes agreed with developers.
32
Your code review shows a test class with 30 copy-pasted lines in every method. How do you refactor it with Java features?
Show answer
Extract repeated steps into private helper methods or a page object, move common setup into @BeforeMethod, and use a DataProvider when only data differs. If the repeated code differs only in a small action, pass that action as a lambda, such as a Consumer<WebDriver>. Rerun the tests after each small refactor to confirm behaviour is unchanged.
33
What is idempotency in REST APIs and why does it matter for testing?
Show answer
An idempotent operation gives the same result no matter how many times it is called. GET, PUT and DELETE should be idempotent; POST usually is not. Testers verify that repeating a PUT does not create duplicates and that a second DELETE returns a sensible status like 404 or 204. Retries in networks and CI make idempotency important to verify.
34
Your API tests started failing with SSL handshake errors on a new test server. What do you do?
Show answer
First confirm the server uses a self-signed or internal certificate. The proper fix is to import the company CA certificate into a truststore and configure REST Assured with trustStore(path, password). As a temporary measure in a test environment only, relaxedHTTPSValidation() skips checks. Never use relaxed validation against production, and raise the certificate issue with the infra team.
35
Cucumber says a step is undefined even though the step definition exists. How do you fix it?
Show answer
Check the glue path in the runner points to the package containing the step classes. Check the step text matches exactly, including quotes and parameter types, since {string} expects quoted text. Confirm the step class is under src/test/java and compiled, the annotation import is io.cucumber.java.en, and the Cucumber versions of core, java and the runner module match. Running with dryRun shows all unmatched steps quickly.
36
How do you test an API that depends on another service that is down?
Show answer
Use mocks or stubs such as WireMock to simulate the dependency and test your service in isolation.
37
What is the difference between the normal, eager and none page load strategies in Selenium?
Show answer
Page load strategy decides when navigation commands like get() return. Normal, the default, waits for the full load event including images and stylesheets. Eager returns when the DOM is ready (DOMContentLoaded), which speeds up heavy pages. None returns immediately after the initial response. With eager or none you must rely on explicit waits for the elements you need. Set it through options.setPageLoadStrategy(PageLoadStrategy.EAGER).
38
How do you pass thread count and duration to a JMeter test from the command line?
Show answer
// In the Thread Group fields use property functions with defaults
Number of Threads: ${__P(users,10)}
Ramp-up period: ${__P(rampup,30)}
Duration (seconds): ${__P(duration,300)}
// Then override them when running
jmeter -n -t load.jmx -l out.jtl -Jusers=200 -Jrampup=120 -Jduration=1800
39
How do you use Cucumber with REST Assured for API BDD tests?
Show answer
Write scenarios in business terms, such as "When a customer places an order for 2 items". In step definitions, build the request with REST Assured, store the Response in a shared scenario context, and assert in Then steps using then().statusCode() and JSON path checks. Keep base URI, auth and specs in a helper class so steps stay short and the same steps serve many features.
40
A test configuration value has to be the same for the whole run and accessed from many classes. How do you implement it?
Show answer
Create a ConfigReader that loads properties once, using a singleton or a static holder initialised lazily in a thread-safe way, and exposes typed getters like getInt("timeout"). Let system properties and environment variables override file values so CI can change them. Keep it read-only after loading so parallel threads cannot change settings mid-run.
