01
Difference between absolute and relative XPath?
Show answer
Absolute starts from the root (/html/...) and breaks easily; relative starts anywhere with // and is more stable, for example //input[@id='email'].

02
How do you pass authentication in an API test?
Show answer
Use headers such as Bearer tokens, basic auth, API keys or OAuth flows; fetch a token in a setup step and reuse it.
03
How do you handle a browser basic authentication pop-up in Selenium?
Show answer
The basic auth dialog is not part of the page, so findElement cannot reach it. The simplest way is putting credentials in the URL, like https://user:pass@site.test, which works in many browsers. In Selenium 4 with Chromium you can register credentials through the HasAuthentication interface: ((HasAuthentication) driver).register(UsernameAndPassword.of("user", "pass")). Keep the credentials in environment variables or a secret store, never in code.
04
Tell me about a time you introduced BDD to a team. How did it go?
Show answer
Situation: requirements were often misread, causing rework late in sprints. Task: I proposed BDD for one module. Action: I ran short three-amigos sessions, wrote example scenarios with the BA, automated them with Cucumber and showed them in sprint review. Result: rework on that module dropped noticeably over two sprints, and the team adopted the practice for other complex stories.
05
How do you log requests and responses in REST Assured?
Show answer
Use given().log().all() for the full request and then().log().all() for the full response. To reduce noise, use log().ifValidationFails() on both, which prints only when a test fails. For a whole suite, set RestAssured.enableLoggingOfRequestAndResponseIfValidationFails() or add RequestLoggingFilter and ResponseLoggingFilter in a shared spec. Mask tokens and passwords before logs reach CI.
06
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.
07
How do you verify that the correct page has loaded in POM?
Show answer
Give each page an isAt() or waitUntilLoaded() method that waits for a unique element, page title or URL fragment. Call it in the constructor or right after navigation. If it fails, throw a clear error such as "Expected Cart page but URL was /login". This catches navigation problems at the right point instead of failing later with a confusing locator error.
08
What are the different types of waits in Selenium?
Show answer
Implicit, explicit (WebDriverWait with ExpectedConditions) and fluent waits; avoid mixing implicit and explicit waits and never rely on Thread.sleep.
09
What is Docker Compose and why is it useful for Selenium Grid?
Show answer
Docker Compose lets you define several containers, their images, ports, environment variables and networks in one docker-compose.yml file and start them together with docker compose up. For Selenium it means a hub plus Chrome, Firefox and Edge nodes, and even the application under test, start with one command on any laptop or CI agent. The file is version-controlled, so every tester and pipeline uses the same Grid setup.
10
How do you integrate Selenium tests with Jenkins?
Show answer
Create a job or pipeline that checks out code, runs mvn test, publishes reports and triggers on commits or schedules.
11
Your Selenium tests in CI produce blank screenshots in headless mode. What could be wrong?
Show answer
The screenshot may be taken before the page renders, the window size in headless mode may be tiny, or the browser is crashing due to low shared memory in Docker. Set --window-size=1920,1080, use the new headless mode, wait for page content before capturing, and add --disable-dev-shm-usage or a larger shm size for containers.
12
Write a declarative Jenkinsfile that runs Maven tests and publishes results.
Show answer
pipeline {
agent any
parameters { choice(name: 'SUITE', choices: ['smoke', 'regression']) }
stages {
stage('Checkout') { steps { checkout scm } }
stage('Test') {
steps { sh "mvn clean test -DsuiteXml=${params.SUITE}.xml" }
}
}
post {
always {
junit 'target/surefire-reports/*.xml'
archiveArtifacts artifacts: 'target/screenshots/**', allowEmptyArchive: true
}
}
}
13
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.
14
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.
15
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.
16
A file download test passes locally but fails in a Grid node. How do you approach it?
Show answer
The file is saved on the remote node, not the machine running the test, so the test cannot find it locally. Options are enabling Selenium Grid's managed downloads with se:downloadsEnabled and fetching the file through the Grid API, sharing a mounted volume with the container, or verifying the download by requesting the file URL with an HTTP client and checking status, size and type.
17
What is dryRun in Cucumber and when do you use it?
Show answer
dryRun=true makes Cucumber parse all feature files and check every step has a matching definition without actually executing anything. It is fast and is useful after writing new features, during refactoring, or as a quick CI gate to catch undefined or ambiguous steps. It also prints snippets for missing step definitions that you can paste and implement.
18
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.
19
A utility method that parses dates from the UI breaks in parallel runs. What might be wrong?
Show answer
It probably uses a shared static SimpleDateFormat, which is not thread-safe, so parallel threads corrupt each other's parsing. Replace it with java.time DateTimeFormatter, which is immutable and thread-safe, and LocalDate or LocalDateTime for values. Generally, avoid shared mutable static objects in test utilities that run in parallel.
20
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.
21
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.
22
File upload tests pass locally but fail when they run on a remote Grid. Why?
Show answer
sendKeys with a file path sends a path that exists on your test machine, but the browser runs on the remote node where that path does not exist. Set a LocalFileDetector on the RemoteWebDriver, using ((RemoteWebDriver) driver).setFileDetector(new LocalFileDetector()), so Selenium zips and transfers the file to the node first. Alternatively mount the test data folder into the node container. Always use absolute paths.
23
How do you handle a dropdown that is not a <select> tag?
Show answer
Click to open the dropdown, then locate the option by its text, e.g. //li[text()='India'], and click it. Add an explicit wait for the animation.
24
How do you upload a file with Selenium?
Show answer
If the element is <input type="file">, use element.sendKeys("C:/path/file.pdf"). Use the Robot class or AutoIt only as a last resort for OS dialogs.
25
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.
26
What is the Rule keyword in Gherkin?
Show answer
Rule, added in Gherkin 6, groups scenarios that illustrate one business rule inside a feature. For example, a Feature: Discounts can have Rule: Orders above 1000 get free delivery, followed by scenarios showing the rule holding and not holding. Each Rule can have its own Background. It makes feature files read like a specification of rules with examples, which helps business stakeholders see exactly what each scenario proves.
27
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.
28
During a load test response times rise sharply. Which server-side metrics do you check?
Show answer
Check CPU and memory usage of application servers, garbage collection pauses and heap usage for Java services, thread pool and connection pool saturation, database slow queries, locks and connection counts, disk I/O and network bandwidth. Also look at load balancer and cache hit rates and error logs. Correlate the timestamp of the slowdown with these graphs in an APM or monitoring tool to find which resource saturated first.
29
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.
30
What is the @Factory annotation in TestNG?
Show answer
@Factory creates test class instances dynamically, each with different constructor data, so all tests in the class run once per instance. For example a factory can create LoginTests for chrome and firefox. It differs from DataProvider, which runs one method many times with different arguments. Factory is useful when a whole class should repeat for each configuration.
31
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.
32
Method overloading vs overriding?
Show answer
Overloading: same method name, different parameters, in the same class (compile time). Overriding: a subclass redefines a parent method with the same signature (runtime polymorphism). WebDriver driver = new ChromeDriver() is runtime polymorphism.
33
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.
34
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.
35
What is a step definition in Cucumber?
Show answer
A step definition is a Java method annotated with @Given, @When or @Then whose expression matches a Gherkin step. When Cucumber runs a feature, it finds the matching method and executes it, passing captured parameters as arguments. Keep step definitions thin: they should call page objects or API helpers rather than contain Selenium code directly, so the same steps stay reusable across many features.
36
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.
37
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.
38
How would you test an API with rate limiting?
Show answer
Read the documented limit, then send requests quickly until you exceed it and assert a 429 Too Many Requests response with headers like Retry-After or remaining quota. Wait for the window to reset and confirm requests succeed again. Also check limits are per user or key as designed. Run these tests in isolation so they do not throttle the rest of the suite.
39
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.
40
What is Postman and how do you automate with it?
Show answer
An API client. Add tests in JavaScript, use environments and collections, and run them with Newman in a CI pipeline.
