01
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.

02
How do you handle dropdowns in Selenium?
Show answer
Use the Select class with selectByVisibleText, selectByValue or selectByIndex; for custom dropdowns click and choose from the list of elements.
03
How do you test that a method throws an expected exception in TestNG?
Show answer
Use @Test(expectedExceptions = IllegalArgumentException.class) and optionally expectedExceptionsMessageRegExp to check the message. The test passes only if that exception is thrown. For more control, use Assert.assertThrows(IllegalArgumentException.class, () -> service.withdraw(-5)), which returns the exception so you can inspect it further. This style is clearer because the check applies to one line, not the whole test.
04
How do you handle authentication types in REST Assured?
Show answer
Basic auth uses auth().preemptive().basic(user, pass). Bearer tokens are set as a header: header("Authorization", "Bearer " + token). OAuth 2.0 can use auth().oauth2(token) after fetching the token from the token endpoint. API keys go in a header or query param. Fetch tokens once per suite or cache them with an expiry check rather than logging in before every test.
05
How do you run Cucumber scenarios in parallel?
Show answer
With TestNG, extend AbstractTestNGCucumberTests and override scenarios() with @DataProvider(parallel = true), then set data-provider-thread-count. With JUnit 5, set cucumber.execution.parallel.enabled=true in junit-platform.properties. Each scenario must own its WebDriver, usually through a ThreadLocal or a per-scenario DI context, and test data must not clash. Parallelism is per scenario, not per step.
06
How do you test page objects themselves, or keep them reliable?
Show answer
Page objects are tested indirectly through a smoke suite that exercises each page method at least once. Keep them simple with no logic beyond waiting and interacting. Add clear error messages in waits, log each action at debug level, and run the smoke suite on every pull request that changes framework code, so a broken page method is caught before regression runs.
07
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.
08
A test configuration value has to be the same for the whole run and accessed from many classes. How do you implement it?
Show answer
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.
09
What is Appium and how does its architecture work?
Show answer
Appium is an open-source tool for automating native, hybrid and mobile web apps on Android and iOS using the W3C WebDriver protocol. Your Java test sends HTTP commands to the Appium server, which forwards them to a platform driver such as UiAutomator2 for Android or XCUITest for iOS. That driver talks to the device and returns results. Because it follows WebDriver, Selenium testers can reuse locators, waits and framework design.
10
Implicit vs explicit vs fluent wait?
Show answer
Implicit wait applies globally to element lookups. Explicit wait waits for a specific condition (WebDriverWait + ExpectedConditions). Fluent wait is an explicit wait with custom polling and ignored exceptions.
11
What is the execution order of TestNG annotations?
Show answer
@BeforeSuite → @BeforeTest → @BeforeClass → @BeforeMethod → @Test → @AfterMethod → @AfterClass → @AfterTest → @AfterSuite.
12
How do you measure and assert API response time in REST Assured?
Show answer
Use then().time(lessThan(2000L)) for a quick check or response.getTimeIn(TimeUnit.MILLISECONDS) to log the value. This measures client-side time, including network, so set generous thresholds and treat it as a smoke signal, not a performance test. For real load and latency percentiles, use tools such as JMeter, Gatling or k6.
13
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.
14
What is the difference between average, median and 95th percentile response time?
Show answer
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.
15
How do you undo a commit that has already been pushed?
Show answer
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.
16
What is the difference between throw and throws?
Show answer
throw actually raises an exception object inside a method; throws declares in the method signature that it may pass an exception to the caller.
17
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.
18
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.
19
Write Java code to start an Android Appium session using UiAutomator2Options.
Show answer
UiAutomator2Options options = new UiAutomator2Options()
.setPlatformName("Android")
.setAutomationName("UiAutomator2")
.setDeviceName("Pixel_7_API_34")
.setApp(System.getProperty("user.dir") + "/apps/shop.apk")
.setAutoGrantPermissions(true)
.setNewCommandTimeout(Duration.ofSeconds(120));
AndroidDriver driver = new AndroidDriver(
new URL("http://127.0.0.1:4723"), options);
driver.manage().timeouts().implicitlyWait(Duration.ZERO);
// use explicit waits in tests
driver.quit();
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
What is shift-left testing?
Show answer
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.
22
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.
23
Write a simple page object class for a login page.
Show answer
public class LoginPage {
private final WebDriver driver;
private final By user = By.id("username");
private final By pass = By.id("password");
private final By submit = By.cssSelector("button[type='submit']");
public LoginPage(WebDriver driver) { this.driver = driver; }
public HomePage loginAs(String u, String p) {
driver.findElement(user).sendKeys(u);
driver.findElement(pass).sendKeys(p);
driver.findElement(submit).click();
return new HomePage(driver);
}
}
24
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().
25
What is the difference between git fetch and git pull?
Show answer
git fetch downloads new commits and branches from the remote but does not change your working files; you can inspect them with git log origin/main. git pull is fetch followed by merge (or rebase if configured) into your current branch. Fetch is safer when you want to review changes before integrating them.
26
POST vs PUT vs PATCH?
Show answer
POST creates a resource, PUT replaces the whole resource (idempotent) and PATCH updates part of it.
27
Your API tests started failing with SSL handshake errors on a new test server. What do you do?
Show answer
First confirm the server uses a self-signed or internal certificate. The proper fix is to import the company CA certificate into a truststore and configure REST Assured with trustStore(path, password). As a temporary measure in a test environment only, relaxedHTTPSValidation() skips checks. Never use relaxed validation against production, and raise the certificate issue with the infra team.
28
What is the difference between Comparable and Comparator in Java?
Show answer
Comparable defines the natural order inside the class (compareTo); Comparator defines custom orders externally (compare), useful for sorting test data in several ways.
29
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.
30
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.
31
Write Selenium code to wait for a loader to disappear and then click a button.
Show answer
WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(15));
wait.until(ExpectedConditions.invisibilityOfElementLocated(
By.cssSelector(".spinner")));
wait.until(ExpectedConditions.elementToBeClickable(
By.id("placeOrder"))).click();
32
What are the main OOP concepts in Java?
Show answer
Encapsulation, inheritance, polymorphism and abstraction. Testers use them to build reusable page classes, base tests and utility libraries.
33
How do you send form parameters and headers in REST Assured?
Show answer
Use formParam("username", "asha") and formParam("password", "pass") for application/x-www-form-urlencoded bodies; REST Assured sets the content type for you. Add headers with header("X-Client", "web") or headers(map) for many at once. Cookies use cookie(name, value). Keep common headers in a RequestSpecification so individual tests only add what is specific to them.
34
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.
35
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.
36
What is idempotency in REST APIs and why does it matter for testing?
Show answer
An idempotent operation gives the same result no matter how many times it is called. GET, PUT and DELETE should be idempotent; POST usually is not. Testers verify that repeating a PUT does not create duplicates and that a second DELETE returns a sensible status like 404 or 204. Retries in networks and CI make idempotency important to verify.
37
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.
38
What are access modifiers in Java?
Show answer
public (everywhere), protected (package and subclasses), default (package) and private (same class), used to control visibility of test utilities.
39
What are the UiAutomator2 and XCUITest drivers in Appium?
Show answer
They are the platform drivers that actually control the device. UiAutomator2 drives Android by installing a small server app on the device that uses Google's UiAutomator framework. XCUITest drives iOS through Apple's XCTest framework via WebDriverAgent, which needs Xcode and signing for real devices. In Appium 2 they are installed separately with appium driver install, so each project picks only the drivers and versions it needs.
40
What is the LoadableComponent pattern in Selenium?
Show answer
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.
