02
How do you handle dropdowns in Selenium?
Show answer
Use the Select class with selectByVisibleText, selectByValue or selectByIndex; for custom dropdowns click and choose from the list of elements.
03
How do you handle environment-specific configuration?
Show answer
Keep URLs and credentials in per-environment config files or variables, choose with a command-line parameter and never hard-code secrets.
04
What are timers in JMeter and why is think time important?
Show answer
By default JMeter fires requests back to back, which is far more aggressive than real users who read pages and fill forms. Timers add delays: Constant Timer, Uniform Random Timer and Gaussian Random Timer add think time, while Constant Throughput Timer and Precise Throughput Timer control request rate. Realistic think time makes the user count meaningful; without it, 100 threads may generate the load of thousands of real users.
05
You need the same test to support Chrome, Firefox and Edge. How would you design driver creation in Java?
Show answer
Use a factory: a BrowserType enum and a DriverFactory.create(BrowserType) that returns the right WebDriver with its options, using a switch. Read the browser from a system property with a default. For remote runs, return RemoteWebDriver with the same options. Tests depend only on the WebDriver interface, so adding a new browser changes one class, following the open-closed principle.
06
Response times are fine with 50 users, but at 300 users the error rate jumps to 20 percent. How do you analyse it?
Show answer
Look at which requests fail and their error codes: 503 or 504 suggest overloaded servers or gateways, connection refused points to exhausted connection pools or ports. Find the user count where errors start by running a stepped ramp-up. Correlate with server metrics such as CPU, thread pools, database connections and GC. Confirm the load generator itself was not overloaded. Report the saturation point and the bottleneck with evidence, not just the error percentage.
07
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.
08
A login action can lead either to the dashboard or to an error message. How should the page object method return?
Show answer
Make the outcome explicit with separate methods instead of one method guessing. For example loginAs(user) returns DashboardPage for valid credentials, while loginExpectingError(user) returns the same LoginPage so the test can check the error. Each method waits for its expected page and fails clearly if it does not appear. This keeps tests readable and avoids returning a generic Object or checking types in tests.
09
How do you run only selected scenarios using tags in Cucumber?
Show answer
Add tags like @smoke or @regression above a Feature or Scenario, then filter with a tag expression. In the runner use @ConfigurationParameter(key = FILTER_TAGS_PROPERTY_NAME, value = "@smoke and not @wip") with the JUnit Platform engine, or pass -Dcucumber.filter.tags="@smoke" from Maven. Tag expressions support and, or, not and brackets, so CI can run smoke on every commit and regression nightly.
10
Difference between ArrayList and LinkedList?
Show answer
ArrayList has fast random access and slower inserts in the middle; LinkedList has fast inserts and deletes but slow access by index.
11
How do you run Appium tests in parallel on several Android devices?
Show answer
Give each device its own session: unique appium:udid, a separate appium:systemPort for UiAutomator2 and, for hybrid apps, a separate chromedriverPort. Store the driver in a ThreadLocal so threads never share it. Pass device details through TestNG parameters or a DataProvider and run with parallel="tests", one test tag per device. One Appium server can handle several sessions, or use a Selenium Grid 4 with Appium nodes or a cloud device farm for larger matrices.
12
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.
13
What is the difference between noReset and fullReset in Appium?
Show answer
By default Appium clears app data between sessions but keeps the app installed. noReset set to true keeps app data and login state, which speeds up tests but can leak state between them. fullReset set to true uninstalls and reinstalls the app, giving the cleanest state but adding time. A common approach is noReset for fast suites with explicit cleanup in the test, and fullReset only for first-launch or onboarding scenarios.
14
Tests pass on QA but fail in the staging pipeline. How do you investigate?
Show answer
Compare what differs: configuration URLs, test data, feature flags, user permissions, network or proxy, browser versions and timing due to slower servers. Check logs and screenshots from staging and rerun one failing test with verbose logging. Often the issue is missing data or a flag. Fix by making environment settings explicit and creating required data in test setup.
15
How do you publish Allure or Extent reports from Jenkins?
Show answer
For Allure, install the Allure Jenkins plugin, configure the commandline tool, and add allure results: [[path: 'target/allure-results']] in the post always block. For Extent, archive the HTML file and use the HTML Publisher plugin to show it as a build link. Keep report history per build and share the link in failure notifications.
16
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);
17
Write Appium Java code to perform a vertical swipe using W3C Actions.
Show answer
// Swipe up from 80% to 20% of the screen height
Dimension size = driver.manage().window().getSize();
int x = size.width / 2;
int startY = (int) (size.height * 0.8);
int endY = (int) (size.height * 0.2);
PointerInput finger = new PointerInput(PointerInput.Kind.TOUCH, "finger");
Sequence swipe = new Sequence(finger, 1);
swipe.addAction(finger.createPointerMove(Duration.ZERO, PointerInput.Origin.viewport(), x, startY));
swipe.addAction(finger.createPointerDown(PointerInput.MouseButton.LEFT.asArg()));
swipe.addAction(finger.createPointerMove(Duration.ofMillis(600), PointerInput.Origin.viewport(), x, endY));
swipe.addAction(finger.createPointerUp(PointerInput.MouseButton.LEFT.asArg()));
driver.perform(List.of(swipe));
18
Tests running inside Docker cannot reach the application running on the host's localhost. Why, and how do you fix it?
Show answer
Inside a container, localhost means the container itself, not the host machine. On Docker Desktop use host.docker.internal as the host name. On Linux add extra_hosts with host.docker.internal:host-gateway, or use the host's IP. A cleaner option is running the application in the same Compose network and calling it by its service name, such as http://web:8080. Make sure the app listens on 0.0.0.0, not only 127.0.0.1.
19
Half of your TestNG tests are skipped in CI with no failure shown. What could cause it?
Show answer
Usually a configuration method failed, such as @BeforeClass or @BeforeSuite throwing an exception, which makes TestNG skip dependent tests. Other causes are dependsOnMethods on a failed test, a group filter excluding setup methods without alwaysRun, or a DataProvider that threw an exception. Check the configuration failures section of the report and the log for the first exception.
20
Business stakeholders never read your feature files. Is BDD still worth it?
Show answer
Partly. Readable scenarios still help testers and developers, but if nobody discusses examples before coding, Cucumber is only an extra layer over normal tests. I would first try to restart three-amigos sessions for complex stories. If the business truly will not engage, I would keep Gherkin only for key business flows and write lower-level tests in plain TestNG to reduce maintenance.
21
How do you make page objects work with dynamic locators, such as a row containing a given name?
Show answer
Write a method that builds the locator from a parameter, for example private By rowFor(String name) { return By.xpath("//tr[td[normalize-space()='" + name + "']]"); }, and expose actions like deleteUser(name). Keep the template in the page class, not in tests. Escape quotes if names may contain them, and prefer CSS with data attributes when the application provides them.
22
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.
23
How would you explain to a manager why mobile automation estimates are higher than web estimates?
Show answer
Situation: a manager questioned why my mobile estimate was nearly double the web one. Task: justify it with facts. Action: I listed the extra work: two platforms with separate locators, device and OS version matrix, slower sessions, app builds and signing, gestures and permissions, and device lab maintenance. I showed timings from a pilot of five tests. Result: the manager accepted a phased plan starting with Android smoke tests, and later estimates were trusted because they were data-backed.
24
How do you decide what to automate?
Show answer
Automate stable, repetitive, high-risk and data-heavy flows (smoke, regression). Skip one-time tests, frequently changing UI and checks needing human judgement. Compare run frequency × manual time with build and maintenance cost.
25
How do you share state between step definition classes in Cucumber Java?
Show answer
Use dependency injection. With cucumber-picocontainer (or Spring/Guice), create a context class such as TestContext holding the driver, page objects and scenario data, and add it as a constructor parameter in every step class. Cucumber creates one instance per scenario and injects the same object everywhere, so state is shared within a scenario but never leaks between scenarios. Avoid static fields because they break parallel runs.
26
How does running Selenium Grid on Kubernetes with autoscaling differ from Docker Compose?
Show answer
Docker Compose runs a fixed number of nodes on one machine, which is simple but limited to that host's CPU and memory. On Kubernetes, typically installed with the Selenium Helm chart, nodes are pods spread across a cluster, and KEDA can scale node pods up based on the queue length and back to zero when idle. It suits large teams with bursty CI demand but needs cluster knowledge and monitoring.
27
You see ConcurrentModificationException in your test utility. What causes it and how do you fix it?
Show answer
It occurs when a collection is modified while being iterated with a for-each loop, for example removing items from an ArrayList inside the loop. Fix by using Iterator.remove(), removeIf(), collecting items to remove separately, or using CopyOnWriteArrayList or ConcurrentHashMap when threads share the collection. In parallel tests, shared lists are a common source.
28
How would you design an automation framework from scratch?
Show answer
Maven project → POM with a BasePage → driver factory with ThreadLocal → config files → data-driven utilities (Excel/JSON) → TestNG or Cucumber runner → logging → Extent reports with screenshots on failure → Jenkins pipeline.
29
How do you capture a screen recording of a mobile test and attach it on failure?
Show answer
// Start before the test, stop and save only if it fails
driver.startRecordingScreen();
// ... test steps ...
String base64 = driver.stopRecordingScreen();
if (result.getStatus() == ITestResult.FAILURE) {
byte[] video = Base64.getDecoder().decode(base64);
Files.write(Paths.get("target/videos/" + result.getName() + ".mp4"), video);
}
30
What is a DataProvider in TestNG?
Show answer
@DataProvider returns Object[][]; a @Test(dataProvider = "name") method runs once per row — the basis of data-driven tests, often reading Excel or JSON.
31
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
32
A mobile test fails intermittently because an animation is still running when you tap. How do you fix it?
Show answer
Wait for a stable end state instead of sleeping, for example wait until the target element is visible and enabled or until a spinner disappears. On test devices and emulators you can disable animations with adb shell settings put global window_animation_scale 0, along with the transition and animator scales. Ask developers for an idle indicator if needed. Disabling animations makes tests faster and more stable, but keep one manual check of the real animations.
33
How do you handle StaleElementReferenceException?
Show answer
Re-locate the element after the DOM refreshes, use explicit waits for the refreshed element, don't keep element references for long, or wrap the action in retry logic.
34
What are TestNG and JUnit 5 differences that matter in automation?
Show answer
TestNG has built-in groups, dependencies, suite XML, DataProvider and flexible parallel options, which suit large Selenium suites. JUnit 5 has a modular platform, tags, parameterized tests, extensions and strong IDE and tool support, and is the default for Spring and Cucumber's JUnit Platform engine. Both are capable; the choice usually follows team standards and existing frameworks.
35
How do you run Selenium tests in Docker containers in CI?
Show answer
Use official Selenium images, either standalone-chrome for simple runs or a Grid with hub and node containers via Docker Compose. The test container or Jenkins agent points RemoteWebDriver to http://selenium-hub:4444. Containers give the same browser version everywhere and are cleaned after each run. Add shm_size for Chrome stability and record videos for failed tests if needed.
36
What is the LoadableComponent pattern in Selenium?
Show answer
LoadableComponent is a Selenium support class that standardises how a page object ensures it is loaded. You extend it and implement load(), which navigates to the page, and isLoaded(), which throws an Error if the page is not ready. Calling get() checks isLoaded and calls load only if needed, then checks again. It gives a consistent, self-verifying way to open pages and fails fast with a clear message.
37
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.
38
Where do you use OOP concepts in your framework?
Show answer
Encapsulation: private locators with public page methods. Inheritance: pages extend a BasePage. Polymorphism: the WebDriver interface for different browsers. Abstraction: utility layers hiding Selenium details.
39
What is JsonPath and how do you use it for nested JSON?
Show answer
JsonPath (Groovy GPath syntax in REST Assured) navigates JSON with dot notation. For {"data":{"items":[{"price":10}]}} you use data.items[0].price. You can also filter: data.items.findAll { it.price > 5 }.name returns names of items costing more than 5. Use it inside body() assertions or via response.jsonPath().getList("data.items.name") to extract values for further checks.
40
How do you make WebDriver thread-safe for parallel runs?
Show answer
Store each driver in a ThreadLocal so every thread gets its own instance and tests do not interfere.
