02
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.
03
Write a REST Assured test using RequestSpecBuilder and ResponseSpecBuilder.
Show answer
RequestSpecification req = new RequestSpecBuilder()
.setBaseUri(Config.baseUrl())
.setContentType(ContentType.JSON)
.addHeader("Authorization", "Bearer " + token)
.build();
ResponseSpecification ok = new ResponseSpecBuilder()
.expectStatusCode(200)
.expectContentType(ContentType.JSON)
.build();
given().spec(req).when().get("/orders").then().spec(ok);
04
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.
05
What new features came with Selenium 4?
Show answer
Relative locators, improved Grid, W3C compliance, new window or tab creation, Chrome DevTools Protocol access and element-level screenshots.
06
How do you switch between windows and tabs?
Show answer
Get getWindowHandles(), loop to find the target, and call driver.switchTo().window(handle); switch back using the stored parent handle.
07
How do you pass parameters from testng.xml?
Show answer
Define parameter name and value in the XML and read them with @Parameters in the test or configuration method.
08
How do you group tests?
Show answer
Tag tests with groups = {"smoke","regression"} and include or exclude them in testng.xml to run chosen sets.
09
A runtime permission pop-up appears on first launch and breaks your Android tests. How do you handle it?
Show answer
The cleanest fix is the capability appium:autoGrantPermissions set to true, which grants all permissions the app declares at install time. If you need to test the permission flow itself, handle the dialog explicitly by waiting for the Allow button using its resource-id and clicking it. Another option is granting a specific permission with adb shell pm grant before the test. Avoid blind try-catch around taps, because it hides real failures.
10
How do you verify that an element is displayed, enabled or selected?
Show answer
Use isDisplayed(), isEnabled() and isSelected() on the WebElement before interacting or asserting.
11
What is Dynamic Grid in Selenium 4?
Show answer
In Dynamic Grid the node does not run browsers itself. It is configured with a Docker socket and a list of browser images, and for each new session it starts a fresh browser container, runs the test and then removes the container. Every test gets a clean browser, and capacity grows without pre-starting many nodes. It can also record video per session. The trade-off is container start-up time for each session.
12
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();
13
How do you build dynamic JSON request bodies without hard-coded strings?
Show answer
Use POJOs with a builder pattern or Lombok @Builder, so tests write User.builder().name("Ravi").role("QA").build(). For quick cases use a HashMap or Jackson ObjectNode. For large templates, keep a JSON file and change fields with a JSON library. Combine with a faker library for unique values. This avoids escaping issues and makes changes to the schema easy to update.
14
What is the difference between parallel="methods", "classes" and "tests" in testng.xml?
Show answer
methods runs each @Test method in its own thread, giving the most parallelism but requiring fully independent tests and thread-safe drivers. classes runs all methods of one class in the same thread, with different classes in parallel. tests runs each <test> tag in parallel, often used to run different browsers. instances is also available for factory instances. thread-count sets the pool size.
15
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
16
Write a docker-compose.yml that runs a Selenium hub with Chrome and Firefox nodes.
Show answer
services:
selenium-hub:
image: selenium/hub:4.25.0
ports:
- "4442:4442"
- "4443:4443"
- "4444:4444"
chrome:
image: selenium/node-chrome:4.25.0
shm_size: 2gb
depends_on:
- selenium-hub
environment:
- SE_EVENT_BUS_HOST=selenium-hub
- SE_EVENT_BUS_PUBLISH_PORT=4442
- SE_EVENT_BUS_SUBSCRIBE_PORT=4443
firefox:
image: selenium/node-firefox:4.25.0
shm_size: 2gb
depends_on:
- selenium-hub
environment:
- SE_EVENT_BUS_HOST=selenium-hub
- SE_EVENT_BUS_PUBLISH_PORT=4442
- SE_EVENT_BUS_SUBSCRIBE_PORT=4443
17
How do you run tests on multiple browsers in parallel in Jenkins?
Show answer
Use a parallel block in the pipeline with a stage per browser, or a matrix directive with axis BROWSER values chrome, firefox and edge. Each branch runs mvn test -Dbrowser=${BROWSER}, ideally against Selenium Grid or containers so agents do not need local browsers. Publish results per branch with clear names so failures show which browser broke.
18
What are Java collections and which ones do testers use most?
Show answer
ArrayList and LinkedList for lists, HashSet for unique values, HashMap for key-value test data, and Iterator for traversing them, for example collecting web elements in a list.
19
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.
20
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.
21
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.
22
What is a quality gate in a CI/CD pipeline?
Show answer
A quality gate is a rule a build must pass before moving forward, such as all smoke tests passing, code coverage above a threshold, no critical static analysis issues, or no new high-severity vulnerabilities. If the gate fails, the pipeline stops and the change is not deployed. Gates make quality an automatic decision instead of a manual check.
23
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.
24
Your Jenkins test stage marks the build green even though tests failed. Why?
Show answer
Possibly testFailureIgnore is set to true in Surefire, the shell step uses || true, or the script swallows Maven's exit code. Sometimes tests catch exceptions and never fail. Check the console log for Maven's BUILD result and Surefire summary. Fix the configuration so failures produce a non-zero exit, or use junit publishing to mark the build unstable when tests fail.
25
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.
26
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);
27
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.
28
How do you assert on an array in a JSON response using Hamcrest?
Show answer
Use collection matchers inside body(). For example body("data.id", hasItems(1, 2)), body("data", hasSize(6)), body("data.email", everyItem(containsString("@"))) and body("data.find { it.id == 3 }.name", equalTo("Neha")). These check the whole collection in one line. For complex rules, extract a List with jsonPath().getList() and assert with Java or AssertJ.
29
Which tests should run at each stage of a CI/CD pipeline?
Show answer
On every commit or pull request: unit tests, static checks and a fast API and UI smoke suite. After deploying to a test environment: broader API and integration tests. Nightly: full UI regression across browsers. Before or after production release: a short production-safe smoke and monitoring checks. Faster feedback first, heavier tests later.
30
How do you get reports, screenshots and downloaded files out of a Docker container?
Show answer
Use volumes. A bind mount maps a host folder into the container, for example -v $(pwd)/target:/app/target, so reports written in the container appear on the CI agent for archiving. Named volumes are managed by Docker and suit data that should survive restarts. For browser downloads, mount the node's download folder or enable the Grid's managed downloads with the se:downloadsEnabled capability to fetch files through the Grid API.
31
What are filters in REST Assured?
Show answer
Filters intercept requests and responses, similar to middleware. They implement the Filter interface and can add headers, refresh tokens, log traffic, or attach request and response details to Allure reports with AllureRestAssured. You add them with given().filter(myFilter) or globally in a RequestSpecification. Filters keep cross-cutting concerns out of individual tests.
32
How do you create a custom parameter type in Cucumber?
Show answer
Annotate a method with @ParameterType, giving a regex and returning a domain object. For example @ParameterType("admin|manager|viewer") public Role role(String name) { return Role.valueOf(name.toUpperCase()); } lets you write steps like "I log in as {role}". It keeps conversion logic in one place, makes steps type-safe and gives clearer errors when an invalid value is used.
33
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.
34
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.
35
How do you read data from Excel or properties files in Java?
Show answer
Use Apache POI for Excel and the Properties class for config files, loaded in a utility class so tests read data instead of hard-coding it.
36
How do you test API security basics as an automation tester?
Show answer
Check that endpoints reject missing or invalid tokens with 401, block users from other users' data with 403 or 404, validate input to prevent injection, do not leak stack traces or sensitive fields, enforce HTTPS and set security headers. Automate these as negative tests in the regression suite and work with the security team for deeper penetration testing.
37
How do you validate an XML response in REST Assured?
Show answer
// REST Assured uses GPath for XML as well as JSON
given()
.accept(ContentType.XML)
.when()
.get("/orders/42")
.then()
.statusCode(200)
.contentType(ContentType.XML)
.body("order.@id", equalTo("42"))
.body("order.items.item.size()", equalTo(3))
.body("order.status", equalTo("SHIPPED"));
38
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.
39
What are the Actions class use cases?
Show answer
Mouse and keyboard actions such as hover, drag and drop, double click, right click and key combinations, built with moveToElement(...).perform().
40
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'].
