Configure plugins such as pretty for console, html:target/cucumber.html for a built-in report and json:target/cucumber.json for tools. The JSON feeds maven-cucumber-reporting or the Jenkins Cucumber Reports plugin. For richer dashboards, add the Allure or Extent Cucumber adapter. Attach screenshots and logs in hooks so failures can be analysed from the report alone.
02
What is the post section in a Jenkins declarative pipeline?
post defines steps that run after stages based on the result: always, success, failure, unstable, changed, fixed and cleanup. In test pipelines, always publishes JUnit results and archives screenshots and reports, failure sends a Slack or email alert, and cleanup removes the workspace. Putting reporting in post ensures results are saved even when tests fail.
03
What is performance testing and what are its main types?
Performance testing checks how fast, stable and scalable a system is under a given workload. Load testing measures behaviour at expected traffic. Stress testing pushes beyond capacity to find the breaking point and how the system recovers. Spike testing applies sudden jumps in users. Soak or endurance testing runs normal load for hours to find leaks. Scalability testing checks whether adding resources increases capacity as expected.
04
What is the difference between @Test(priority) and dependsOnMethods in TestNG?
priority only orders tests; a lower number runs first, and a failed test does not stop the others. dependsOnMethods creates a real dependency: if the parent test fails, dependent tests are skipped. Both make tests order-dependent, which hurts parallel runs and isolation, so use them sparingly. Prefer independent tests with their own setup.
05
What is WebDriver and how does it communicate with the browser?
The file path is probably hard-coded or relative to the IDE working directory, or uses Windows backslashes while Jenkins runs on Linux. Load the file from the classpath with getClass().getClassLoader().getResourceAsStream("config.properties") and keep it in src/test/resources, or build paths with Paths.get. Also check the file is committed to Git and not ignored.
07
What is the difference between @BeforeTest and @BeforeMethod?
double uses binary floating point, which cannot represent many decimal values exactly, so small rounding errors appear. For money, use BigDecimal created from strings and compare with compareTo(), or compare doubles with a tolerance such as Assert.assertEquals(actual, expected, 0.001). Also strip currency symbols and commas before parsing UI text.
09
How do you make WebDriver thread-safe for parallel runs?
Do not assert on positions when the API does not guarantee order. Use order-independent Hamcrest matchers such as hasItem, hasItems or containsInAnyOrder on the extracted field, for example body("name", hasItems("Pen", "Book")). Or use GPath filtering like find { it.id == 42 } to pick the right item before checking its fields. If order matters for the feature, raise it as a requirement and request a sort parameter.
11
What do number of threads, ramp-up period and loop count mean in a JMeter Thread Group?
Number of threads is how many virtual users run in parallel. Ramp-up period is the time JMeter takes to start all of them, so 100 threads with a 50-second ramp-up starts two users per second. Loop count is how many times each user repeats the samplers, or you can set a duration instead. A gradual ramp-up avoids an unrealistic burst at the start and shows where response times begin to degrade.
Put explicit waits in page methods or BasePage helpers, not in tests. For example click() waits for elementToBeClickable before clicking, and a page's isLoaded() waits for a key element. Avoid Thread.sleep and avoid mixing implicit and explicit waits. Keep the timeout configurable so CI can use a slightly longer value than local runs.
13
What is the difference between a Docker image and a container?
An image is a read-only template that contains an operating system layer, software and configuration, for example selenium/standalone-chrome with Chrome and ChromeDriver installed. A container is a running instance of an image with its own process, network and writable layer. You can start many containers from one image and destroy them after a test run. This is why every run starts from the same clean browser environment.
14
What is the difference between driver.close() and driver.quit()?
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 test a responsive page in a mobile viewport using Selenium?
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.
22
How do you validate a response against a JSON schema in REST Assured?
Add the json-schema-validator dependency, place the schema file in src/test/resources, and assert with then().body(matchesJsonSchemaInClasspath("user-schema.json")). Schema validation checks field types, required fields and structure, so it catches contract changes that value checks might miss. It complements, not replaces, assertions on business values like status or totals.
23
Tests run fine on Chrome but fail on Firefox at the same step. How do you investigate?
Rerun on Firefox with screenshots and logs. Common causes are timing differences, different default window sizes, unsupported CSS or JavaScript behaviour, alerts handled differently, or a driver version mismatch. Compare the DOM in both browsers at that step. Fix by using explicit waits, setting window size, and reporting genuine browser bugs to developers.
24
How do you keep your Java and automation skills up to date?
Situation: tools change fast, and my team was still on older Selenium and Java versions. Task: keep myself and the framework current. Action: I follow release notes, try new features in a small personal project, and present one useful change to the team each quarter, such as moving to java.time or Selenium 4 relative locators. Result: we upgraded smoothly and I became the go-to person for upgrades.
Path params are part of the URL path and identify a resource, such as /users/{id}; you set them with pathParam("id", 5). Query params come after ? and filter or modify the result, such as /users?page=2; you set them with queryParam("page", 2). REST Assured URL-encodes both. Using named params instead of string concatenation makes tests cleaner and safer.
28
How do you create a custom parameter type in Cucumber?
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.
29
Difference between an abstract class and an interface?
An abstract class can hold state and concrete methods; an interface defines a contract (with default methods since Java 8). A class extends one abstract class but can implement many interfaces.
30
How do you include and exclude groups in testng.xml?
Inside a <test>, add <groups><run><include name="smoke"/><exclude name="broken"/></run></groups>. Only methods in the included groups run, minus excluded ones. Configuration methods must have alwaysRun = true or belong to the groups, or they will be skipped. You can also pass -Dgroups=smoke from Maven Surefire for CI selection.
31
What are page components or page fragments in POM?
Components are classes for UI parts that repeat across pages, such as the header, search bar, date picker or a data table. A page object then has-a component: homePage.header().search("laptop"). This follows composition over inheritance, avoids duplicate locators and matches modern component-based frontends. Components are usually scoped to a root WebElement so locators search only inside that element.
32
What are the standalone, hub and node, and distributed modes of Selenium Grid 4?
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.
Split pages into components for repeated or complex areas, keep only user actions as public methods, move generic helpers to BasePage or utilities, and avoid one method per element. If a page has distinct modes like view and edit, use separate classes. Review page classes during code review and refactor when they cross a few hundred lines.
35
A TestNG test passes when run alone but fails when the full class runs. What do you check?
Look for shared state between methods: instance or static fields changed by earlier tests, data created or deleted by another test, cookies or logged-in session kept in the same browser, and priority or order assumptions. Run the class in a different order to confirm. Fix by resetting state in @BeforeMethod, creating unique data per test and avoiding static fields.
36
What is correlation in JMeter and why is it needed?
Correlation means capturing dynamic values from one response and passing them into later requests. Session ids, CSRF tokens, auth tokens and order ids change every run, so a recorded script with hard-coded values fails on replay. In JMeter you use post-processors such as JSON Extractor, Regular Expression Extractor or CSS Selector Extractor to save the value into a variable, then reference it as ${token} in later headers or bodies.
37
What is a Jenkins agent and how do labels help run tests?
An agent is a machine or container that runs build steps on behalf of the Jenkins controller. Labels are tags given to agents, such as linux, docker or windows-chrome. In a pipeline, agent { label 'docker' } sends the job to a matching agent. Testers use labels to send UI tests to agents with browsers or Docker installed, and to keep heavy test runs off the controller, which should only coordinate.
38
What is the difference between noReset and fullReset in Appium?
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.
39
How do you record videos of tests running on a Docker Selenium Grid?
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.

Write a JSR223 Groovy PostProcessor that reads a JSON response and stores a value as a JMeter variable.
// JSR223 PostProcessor, language: groovy
import groovy.json.JsonSlurper
def body = prev.getResponseDataAsString()
def json = new JsonSlurper().parseText(body)
if (json?.orderId) {
vars.put('orderId', json.orderId.toString())
} else {
prev.setSuccessful(false)
prev.setResponseMessage('orderId missing in response')
}
