02
What is Docker and how does it help tests?
Show answer
Docker packages tools in containers so tests run identically everywhere; Selenium Grid and browsers can be started quickly in containers.
03
How do you test a responsive page in a mobile viewport using Selenium?
Show answer
For layout checks you can set the window size, like driver.manage().window().setSize(new Dimension(390, 844)). For closer emulation in Chrome use mobile emulation in ChromeOptions: options.setExperimentalOption("mobileEmulation", Map.of("deviceName", "Pixel 7")), which also sets the user agent, pixel ratio and touch events. This catches responsive layout bugs quickly, but it is not a replacement for testing on real mobile browsers.
04
What is the difference between extract().response() and extract().path()?
Show answer
extract().response() returns the full Response object, so you can read status, headers, cookies, body as string, and use jsonPath() several times. extract().path("field") returns one value directly from the body. Use path() when you need a single value like an id or token, and response() when you need many details or want to log the response.
05
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.
06
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.
07
What causes an AmbiguousStepDefinitionsException?
Show answer
It occurs when one Gherkin step matches two or more step definitions, usually because of broad regular expressions or duplicate methods in different classes within the glue. Fix it by making expressions more specific, anchoring regexes with ^ and $, or removing the duplicate. Keeping step definitions organised by domain and reviewing new steps in pull requests prevents it.
08
How do you record videos of tests running on a Docker Selenium Grid?
Show answer
Add the selenium/video image as a sidecar container next to each node, sharing the node's display through DISPLAY_CONTAINER_NAME, and mount a folder for the mp4 files. Newer Grid versions also support recording per session by setting the se:recordVideo capability with Dynamic Grid. Name videos with se:name so they match test names. Keep videos only for failed tests or for a few days, because they use a lot of disk space.
09
Mobile tests pass on the emulator but fail on a low-end real device. How do you investigate?
Show answer
Low-end devices are slower, so fixed waits and short timeouts expire before screens render. Replace sleeps with explicit waits and increase timeouts sensibly. Check for vendor-specific pop-ups, battery optimisation dialogs or different keyboards on that brand. Compare screen size and resolution, since coordinate-based taps break. Collect device logs with adb logcat and screen recordings to see what the app was doing. Also check whether the app crashed due to low memory.
10
How does the DataProvider annotation work?
Show answer
A method annotated with @DataProvider returns a 2D object array and the test with dataProvider = "name" runs once per row.
11
How do you automate a two-factor authentication step in a test environment?
Show answer
Do not try to read SMS from a real phone. Ask developers for a test-only approach: a fixed OTP for test users, a bypass flag in non-production, or an API to fetch the latest OTP. For authenticator apps, store the test account's TOTP secret and generate codes in Java with a TOTP library. Keep production 2FA untouched and secrets in the CI credential store.
12
A stakeholder asks whether the system can handle 10,000 users. How do you plan the performance test?
Show answer
First clarify what 10,000 users means: concurrent sessions, users per hour or requests per second, and which journeys they perform. Use production analytics to build the workload mix and think times, then agree on SLAs like 95th percentile under two seconds and errors under one percent. Prepare a production-like environment and data, plan baseline, load, stress and soak runs, set up monitoring, and share a report with clear limits and bottlenecks.
13
How do you set up distributed load testing in JMeter?
Show answer
One controller machine coordinates several worker machines that generate the load. On each worker start jmeter-server with the same JMeter and Java versions, place CSV files locally and open the RMI ports in the firewall. On the controller list the workers in remote_hosts in jmeter.properties, or pass -R host1,host2, and run in non-GUI mode with -r or -R. Remember that thread counts multiply per worker, so 100 threads on 4 workers gives 400 users.
14
What is contract testing?
Show answer
Verifying that a provider and consumer agree on request and response formats, using tools like Pact, to catch breaking changes early.
15
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);
}
16
What is the scope of a step definition class instance in Cucumber?
Show answer
Cucumber creates a new instance of every glue class for each scenario. Instance fields therefore reset between scenarios, which keeps scenarios isolated. This is why you should not rely on static variables for state: they survive across scenarios and threads, causing order-dependent failures and clashes in parallel runs. Share state through injected context objects instead.
17
How do you handle a web table in Selenium?
Show answer
Locate rows and columns with XPath such as //table//tr and //td, loop through them to read or click cells, or build the XPath dynamically from the row text.
18
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).
19
A click works locally but throws ElementClickInterceptedException in CI. How do you fix it?
Show answer
Another element, such as a cookie banner, loader overlay or sticky header, covers the target. In CI the window is often smaller, so the layout differs. Set a fixed window size, wait for the overlay to disappear with invisibilityOfElementLocated, close banners in setup and scroll the element into view. Use a JavaScript click only as a last resort, since it bypasses real user behaviour.
20
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.
21
What is RequestSpecification in REST Assured and why use it?
Show answer
RequestSpecification holds common request settings such as base URI, base path, headers, content type, authentication and filters. You build it once with RequestSpecBuilder and reuse it with given().spec(reqSpec). This removes repetition, keeps environment settings in one place and makes switching between QA and staging easy. ResponseSpecification does the same for common assertions like status code and content type.
22
Tell me about a time you had to automate a very complex or unusual UI.
Show answer
Situation: our app had a drag-and-drop dashboard builder built on canvas. Task: automate the key layout flows. Action: I tried the Actions class, found canvas elements were not in the DOM, and worked with developers to expose test hooks and an API to verify saved layouts. Result: we automated the main flows reliably, combining a few UI actions with API checks.
23
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.
24
How do you handle iframes?
Show answer
switchTo().frame(index, name or element) enters the frame, and switchTo().defaultContent() returns to the main page.
25
A third-party payment API is slow and makes your tests time out in CI. What do you do?
Show answer
Separate concerns: for most functional tests, stub the payment API with WireMock returning success, failure and timeout responses, so tests are fast and deterministic. Keep a small set of integration tests against the sandbox, with longer timeouts and retries for network errors, run on a schedule. Report sandbox slowness separately so it does not block every pull request.
26
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.
27
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);
28
You must read test data from a 50,000-row CSV for a data-driven test. How do you handle it efficiently in Java?
Show answer
Do not load everything as one giant DataProvider; that creates thousands of UI tests. First question whether all rows need UI runs; most can be validated at API level. Read the file with BufferedReader or Files.lines() as a stream, filter to the rows you need, and use a lazy Iterator<Object[]> DataProvider so rows load as tests run, keeping memory low.
29
How does Appium automate iOS apps and what setup is required?
Show answer
Appium uses the XCUITest driver, which builds and installs WebDriverAgent on the simulator or device. WebDriverAgent is a small XCTest-based server that receives commands and drives the UI. You need a Mac with Xcode, the iOS SDK and command line tools. For real devices you also need a valid Apple developer team, provisioning profile and signed WebDriverAgent. Most iOS setup failures come from signing problems or Xcode and iOS version mismatches.
30
How do you handle a test that is flaky only in headless mode?
Show answer
Set window size explicitly, use proper waits, check animations and viewport differences, and capture screenshots and logs to find timing issues.
31
Describe a time you improved the maintainability of an automation framework.
Show answer
Situation: our suite had duplicated locators across 200 tests and each UI release broke many of them. Task: reduce maintenance effort. Action: I introduced page objects and components for the top ten pages, added data-testid attributes with the developers and wrote a short guide. Result: fixing a UI change went from half a day to under an hour, and new joiners wrote tests faster.
32
Tell me about a time you led the design of a test framework for a new project.
Show answer
Situation: a new product had no automation and a three-month release target. Task: I was asked to set up the framework and guide two juniors. Action: I chose Java, TestNG, Selenium with POM and REST Assured, set up Maven, Jenkins and Allure, wrote conventions and reviewed every pull request early on. Result: we had 250 stable tests in CI before release, and the juniors could extend it independently.
33
What is the difference between static and non-static members?
Show answer
Static members belong to the class and are shared by all instances; non-static members belong to each object.
34
What are the disadvantages of POM?
Show answer
POM adds upfront design effort and extra classes, which can feel heavy for tiny projects. Poorly designed page objects become large god classes, mix assertions with actions, or use deep inheritance chains that are hard to follow. It also does not solve flaky waits or bad test data by itself. Good conventions, components and code reviews are needed to get its benefits.
35
Write a TestNG listener that logs test start and failure.
Show answer
public class LogListener implements ITestListener {
@Override
public void onTestStart(ITestResult r) {
System.out.println("START: " + r.getMethod().getMethodName());
}
@Override
public void onTestFailure(ITestResult r) {
System.out.println("FAIL: " + r.getName() + " - " + r.getThrowable());
}
}
// register with @Listeners(LogListener.class) or <listeners> in testng.xml
36
What is the difference between open and closed workload models in load testing?
Show answer
In a closed model a fixed number of users loop through the scenario, so when the server slows down, users wait and the arrival rate drops, which can hide problems. In an open model new requests arrive at a set rate regardless of response time, like real internet traffic, so a slow server builds a queue. JMeter thread groups are closed by default; the Open Model Thread Group or throughput timers approximate open workloads.
37
What is ITestContext in TestNG and how can you use it to share data?
Show answer
ITestContext represents one test tag from testng.xml and is passed to listeners and configuration methods. It holds the suite, included methods and results, and has setAttribute and getAttribute to share values, such as an auth token created in @BeforeTest and read by later classes. Because it is shared by every thread in that test tag, store only thread-safe or read-only data there, not WebDriver instances during parallel runs.
38
What are try-with-resources and why use them?
Show answer
A try block that automatically closes resources such as file readers or streams, preventing leaks without a finally block.
39
How do you switch between native and webview contexts in a hybrid app?
Show answer
// Requires the webview to be debuggable in the app build
Set<String> contexts = driver.getContextHandles();
for (String ctx : contexts) {
if (ctx.startsWith("WEBVIEW")) {
driver.context(ctx);
break;
}
}
driver.findElement(By.cssSelector("#email")).sendKeys("qa@test.com");
// back to native controls
driver.context("NATIVE_APP");
40
How do you test an API that returns paginated results?
Show answer
Call the first page, check page size, total count and the next link or cursor. Loop through pages until there is no next page, collecting IDs, then assert no duplicates and the total matches the reported count. Also test edge cases: page 0, a page beyond the last, invalid page size and sorting stability. Cap the loop to avoid endless runs if the API misbehaves.
