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.
02
A test configuration value has to be the same for the whole run and accessed from many classes. How do you implement it?
Create a ConfigReader that loads properties once, using a singleton or a static holder initialised lazily in a thread-safe way, and exposes typed getters like getInt("timeout"). Let system properties and environment variables override file values so CI can change them. Keep it read-only after loading so parallel threads cannot change settings mid-run.
03
What is the execution order of TestNG annotations?
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.
06
How do you handle a test that is flaky only in headless mode?
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.
12
How do you publish Allure or Extent reports from Jenkins?
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.
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.
15
Tell me about a time you mentored a junior tester in Java and automation.
Situation: two new joiners from manual testing struggled with framework code. Task: help them contribute within a sprint. Action: I paired with them daily for an hour, gave small tasks like adding a locator then a full test, and reviewed their code with explanations rather than rewriting it. Result: within three weeks both were writing tests independently, and our automation backlog shrank.
16
How do you run Selenium tests in Docker containers in CI?
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.
17
How do you undo a commit that has already been pushed?
Use git revert <commit>, which creates a new commit that reverses the changes and keeps history intact, safe for shared branches. git reset moves the branch pointer backwards and is fine for local commits, but resetting and force-pushing a shared branch rewrites history and breaks teammates' clones. If force push is truly needed, use --force-with-lease and tell the team.
Shift-left means testing earlier in the development cycle: reviewing requirements, writing acceptance criteria and test cases before coding, running unit and API tests on every commit, and giving developers fast feedback. Defects found early are cheaper to fix. In practice SDETs pair with developers, add tests to pull request pipelines and test APIs before the UI is built.
19
Tests on the Grid fail with SessionNotCreatedException saying the new session request timed out. What do you check?
It means no matching free slot appeared in time. Check the Grid UI to see whether nodes are registered and whether their capabilities match the request, such as browser name, version or platform. Compare the test thread count with total slots, since extra threads just wait in the queue. Look for stuck sessions holding slots after aborted builds. Then increase capacity, reduce threads, or raise the session request timeout.
20
How do you read data from Excel or properties files in Java?
Likely shared state. Common causes are static RestAssured settings changed by one test, shared test data like the same user being updated by two tests, token reuse after another test logged out, or rate limits. Fix by using per-test RequestSpecification instead of global statics, creating unique data per test, isolating tokens, and checking server rate-limit responses such as 429.
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.
23
What are Appium capabilities and which ones are essential to start a session?
Capabilities are key-value settings sent when creating a session that tell Appium what to automate. Essential ones are platformName, appium:automationName (UiAutomator2 or XCUITest), appium:deviceName or appium:udid, and either appium:app (path to the apk or ipa) or appPackage and appActivity for an installed Android app. In Appium 2 non-standard capabilities need the appium: prefix. In Java you usually set them through UiAutomator2Options or XCUITestOptions.
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.
A special method that initialises an object. It can be overloaded with different parameters, and testers use it to pass the WebDriver into page classes.
27
How would you design a CI pipeline for nightly regression?
Schedule the job, spin up environments or containers, run suites in parallel, store reports and screenshots, notify failures on Slack or email and track trends.
Surefire runs unit tests in the test phase and stops the build as soon as tests fail. Failsafe runs integration tests in the integration-test phase and checks results later in the verify phase, so post-integration-test steps, like stopping a server or Docker containers, still run after failures. By default Failsafe picks classes named *IT. Many teams run UI and API suites through Failsafe with mvn verify for that reason.
Add the rerun plugin, for example rerun:target/failed.txt, to the main runner. It writes the location of each failed scenario. Create a second runner whose features point to @target/failed.txt and run it after the main run in Maven or Jenkins. Use reruns to separate real failures from flaky ones, but track flaky scenarios and fix them instead of hiding them.

Write Java code to find the second largest number in an integer array.
public static int secondLargest(int[] nums) {
int first = Integer.MIN_VALUE, second = Integer.MIN_VALUE;
for (int n : nums) {
if (n > first) {
second = first;
first = n;
} else if (n > second && n != first) {
second = n;
}
}
if (second == Integer.MIN_VALUE) throw new IllegalArgumentException("No second largest");
return second;
}
32
What is the difference between average, median and 95th percentile response time?
Average is the sum divided by count, so a few very slow requests can distort it. Median is the middle value, meaning half the requests were faster. The 95th percentile means 95 percent of requests were faster than that value, which reflects what most users experience including slow cases. SLAs are usually written on 90th, 95th or 99th percentiles because averages hide long tails that frustrate real users.
33
What is the difference between imperative and declarative Gherkin?
Imperative Gherkin lists UI actions: enter username, enter password, click submit. Declarative Gherkin states intent: Given a registered customer is logged in. Declarative steps are shorter, survive UI changes and are understood by business people; the UI detail lives in step definitions and page objects. Imperative style is acceptable only when the exact interaction is the behaviour being tested.
34
Parallel TestNG runs open browsers that interact with each other's tests. How do you fix it?
The WebDriver is shared, probably through a static field. Replace it with a ThreadLocal<WebDriver> in a DriverManager, create the driver in @BeforeMethod and call quit() and remove() in @AfterMethod(alwaysRun = true). Make page objects take the driver from the current thread. Also check test data, reports and loggers are thread-safe.
35
How do you handle environment-specific configuration?
compile is the default and available everywhere. test is only for test compile and run, such as TestNG and REST Assured. provided is needed for compiling but supplied at runtime by the container. runtime is not needed to compile but needed to run, like JDBC drivers. system and import are rarer. In test projects, mark test libraries as test scope unless framework code in src/main uses them.
39
What are appPackage and appActivity in Android automation?
appPackage is the unique application id of an Android app, such as com.example.shop, and appActivity is the activity screen that Appium launches first, such as .MainActivity. Together they let Appium start an app that is already installed without passing the apk path. You can find them with adb shell dumpsys window or by reading the manifest. A wrong activity name is a common reason a session fails to start.
40
How do you get reports, screenshots and downloaded files out of a Docker container?
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.
