02
What are listeners in TestNG?
Show answer
Classes like ITestListener that react to events such as test start, success or failure, commonly used for screenshots and reporting.
03
What is a Jenkins agent and how do labels help run tests?
Show answer
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.
04
What is the difference between a declarative and a scripted Jenkins pipeline?
Show answer
Declarative pipelines use a fixed structure: pipeline, agent, stages, steps, post, with built-in options and validation; they are easier to read and are the recommended default. Scripted pipelines use node blocks and full Groovy, giving more flexibility for complex logic but making them harder to maintain. Most test pipelines use declarative syntax with small script blocks only where needed.
05
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.
06
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.
07
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.
08
What is the Fluent Page Object pattern?
Show answer
Fluent page objects return objects from every action so a test reads like a sentence, for example new SearchPage(driver).searchFor("phone").filterByBrand("X").sortByPrice().firstResult(). It improves readability and models navigation. The risk is long chains that hide failures, so keep chains to a single journey and use clear method names that show which page you end on.
09
Tell me about a time you moved from web automation to mobile automation.
Show answer
Situation: my team needed Android regression tests and I only knew Selenium. Task: deliver a smoke suite in one month. Action: I learned Appium 2 setup, used Appium Inspector to find locators, asked developers to add accessibility ids, and reused our TestNG, POM and reporting structure with a new driver factory. Result: twenty smoke tests ran nightly on emulators within four weeks, and release smoke testing dropped from half a day to forty minutes.
10
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.
11
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.
12
In a hybrid Android app, driver.getContextHandles() returns only NATIVE_APP. Why?
Show answer
The webview is probably not debuggable. Android only exposes a webview to automation when the app calls WebView.setWebContentsDebuggingEnabled(true), which developers usually enable only in debug builds, so ask for a debug or test build. Also wait until the webview screen is actually loaded before reading contexts. If the app uses Chrome custom tabs, that is a separate Chrome process, not a webview. Finally check that a compatible Chromedriver is available to Appium.
13
How do you verify response time and headers in REST Assured?
Show answer
Use then().time(lessThan(2000L)) and then().header("Content-Type", containsString("json")) along with body assertions.
14
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.
15
What is the difference between hard and soft assertions?
Show answer
Hard assert stops the test at the first failure; SoftAssert collects failures and reports them together when assertAll() is called.
16
Write Java code to create a RemoteWebDriver for a Selenium Grid using ChromeOptions.
Show answer
String gridUrl = System.getProperty("grid.url", "http://localhost:4444");
ChromeOptions options = new ChromeOptions();
options.addArguments("--window-size=1920,1080");
options.setCapability("se:name", "Login smoke test");
WebDriver driver = new RemoteWebDriver(new URL(gridUrl), options);
try {
driver.get("https://app.test/login");
} finally {
driver.quit();
}
17
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.
18
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.
19
Tell me about a time a flaky test cost your team time and how you fixed it permanently.
Show answer
Situation: a checkout test failed about one run in five and the team started ignoring red builds. Task: fix the root cause, not just rerun it. Action: I added logs and screenshots, found it raced with an async price recalculation, replaced a fixed sleep with a wait on the updated total and asked developers for a loading flag. Result: zero failures in the next sixty runs, and the team trusted red builds again.
20
Why is JSR223 with Groovy preferred over BeanShell in JMeter?
Show answer
JSR223 elements with Groovy compile scripts once and cache them, so they run much faster and use less CPU under load. BeanShell is interpreted on every call and becomes a bottleneck at high thread counts. Groovy also supports modern Java syntax and is the default JSR223 language. Enable caching by keeping the cache compiled script option on and passing values through vars or parameters, not by embedding ${} inside the script.
21
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.
22
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.
23
Tests running inside Docker cannot reach the application running on the host's localhost. Why, and how do you fix it?
Show answer
Inside a container, localhost means the container itself, not the host machine. On Docker Desktop use host.docker.internal as the host name. On Linux add extra_hosts with host.docker.internal:host-gateway, or use the host's IP. A cleaner option is running the application in the same Compose network and calling it by its service name, such as http://web:8080. Make sure the app listens on 0.0.0.0, not only 127.0.0.1.
24
What is the difference between getText() and getAttribute()?
Show answer
getText returns visible inner text; getAttribute returns an HTML attribute or property such as value, href or class.
25
How do you make page objects work with dynamic locators, such as a row containing a given name?
Show answer
Write a method that builds the locator from a parameter, for example private By rowFor(String name) { return By.xpath("//tr[td[normalize-space()='" + name + "']]"); }, and expose actions like deleteUser(name). Keep the template in the page class, not in tests. Escape quotes if names may contain them, and prefer CSS with data attributes when the application provides them.
26
What makes a good Gherkin scenario?
Show answer
A good scenario describes one behaviour in business language, uses declarative steps ("When the user logs in as a manager") rather than UI clicks ("When I click the login button"), has one When and a clear Then, stays under about 5 to 7 steps and is independent of other scenarios. The title should state the rule being checked so failures are understood without opening the code.
27
What are exceptions and how do you handle them?
Show answer
Runtime events that disrupt flow. Use try-catch-finally, throw, throws, and custom exceptions; checked exceptions must be handled while unchecked ones need not be.
28
After aborted Jenkins builds, Grid slots stay busy and new tests wait. How do you handle it?
Show answer
When a build is killed, driver.quit() never runs, so sessions stay open until the node notices. Set a sensible session timeout on nodes, such as SE_NODE_SESSION_TIMEOUT of 300 seconds, so idle sessions are cleaned up. Always call quit in an @AfterMethod with alwaysRun or a finally block. In CI, bring the Compose Grid up per build and tear it down in a post always step, so each build gets a fresh Grid.
29
Your team asks whether mobile tests should run on emulators or real devices. What do you recommend?
Show answer
Use both, for different purposes. Emulators and simulators are cheap, fast to reset and easy to run in CI, so they suit smoke and regression runs on every commit. Real devices reveal issues emulators hide: performance on low-end hardware, camera, biometrics, push notifications, network changes and vendor-specific Android skins. A common plan is emulators in the pull request pipeline and a nightly run on a small matrix of real devices covering the most-used models.
30
How do you handle waits inside page objects?
Show answer
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.
31
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.
32
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.
33
A login action can lead either to the dashboard or to an error message. How should the page object method return?
Show answer
Make the outcome explicit with separate methods instead of one method guessing. For example loginAs(user) returns DashboardPage for valid credentials, while loginExpectingError(user) returns the same LoginPage so the test can check the error. Each method waits for its expected page and fails clearly if it does not appear. This keeps tests readable and avoids returning a generic Object or checking types in tests.
34
How do you validate a response against a JSON schema in REST Assured?
Show answer
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.
35
What is git cherry-pick?
Show answer
git cherry-pick <commit> applies the changes of one specific commit onto your current branch, creating a new commit. It is useful when a fix on one branch, such as a locator fix on develop, is urgently needed on a release branch without merging everything else. Overuse creates duplicate commits and confusing history, so prefer normal merges when possible.
36
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.
37
What is data-driven testing?
Show answer
Running the same test logic with multiple data sets from Excel, CSV, JSON or a database, so coverage increases without duplicating code.
38
What are Java 8 streams and lambdas?
Show answer
Lambdas are short anonymous functions; streams process collections declaratively with filter, map and collect, for example filtering link text from a list of elements.
39
Tests on the Grid fail with SessionNotCreatedException saying the new session request timed out. What do you check?
Show answer
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.
40
What are generics in Java and how do they help in a test framework?
Show answer
Generics let classes and methods work with a type parameter while keeping compile-time type safety, such as List<String> or a method <T> T readJson(String path, Class<T> type). In a framework they let you write one reusable helper for many types, for example a generic API client that deserializes responses into any POJO, or a BasePage method that returns the correct page type for chaining. They remove casts and catch type errors at compile time.
