Accenture Automation Testing Interview Questions & Answers

Use then().statusCode(200).body("data.id", equalTo(5)), or extract() the response and assert fields with JsonPath.

Do not automate it; ask for a test environment where CAPTCHA is disabled or use test keys, or a bypass token agreed with developers.

Use the Select class with selectByVisibleText, selectByValue or selectByIndex; for custom dropdowns click and choose from the list of elements.

final makes a variable, method or class unchangeable; finally is a block that always runs after try-catch; finalize is a deprecated method called before garbage collection.

TestNG reports, ExtentReports and Allure give charts, screenshots and logs that are easy to share with the team.

Arrays have a fixed size and can hold primitives; ArrayList grows dynamically, holds objects and offers helper methods.

throw actually raises an exception object inside a method; throws declares in the method signature that it may pass an exception to the caller.

Static members belong to the class and are shared by all instances; non-static members belong to each object.

Hard assert stops the test at the first failure; SoftAssert collects failures and reports them together when assertAll() is called.

A method annotated with @DataProvider returns a 2D object array and the test with dataProvider = "name" runs once per row.

ArrayList stores an ordered list (e.g. all product names on a page). HashMap stores key–value pairs (e.g. test data or config properties).

Classes like ITestListener that react to events such as test start, success or failure, commonly used for screenshots and reporting.

Define parameter name and value in the XML and read them with @Parameters in the test or configuration method.

Git tracks changes, enables code review, branching and rollback and lets teams collaborate on the framework safely.

Code pushed to Git → Jenkins job triggers (webhook or schedule) → mvn clean test with the suite XML → reports and screenshots published → notifications on Slack/email → failures triaged before release.

An open-source suite for browser automation: WebDriver, IDE, Grid and the older RC. WebDriver controls browsers through their native drivers.

An interface for systems to talk to each other. GET reads, POST creates, PUT replaces, PATCH updates partially and DELETE removes.

Lambdas are short anonymous functions; streams process collections declaratively with filter, map and collect, for example filtering link text from a list of elements.

BeforeSuite, BeforeTest, BeforeClass, BeforeMethod, Test, AfterMethod, AfterClass, AfterTest and AfterSuite.

A configuration file to define suites, tests, classes, groups, parameters and parallel execution settings.

this refers to the current object; super refers to the parent class, used to call parent constructors and methods.

Use isDisplayed(), isEnabled() and isSelected() on the WebElement before interacting or asserting.

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.

It makes a test run only after specified tests pass, otherwise it is skipped. Use sparingly as it creates coupled tests.

public (everywhere), protected (package and subclasses), default (package) and private (same class), used to control visibility of test utilities.

@BeforeTest runs once before all methods in a test tag of testng.xml; @BeforeMethod runs before every test method.

Locators such as above, below, toLeftOf and near that find elements by their position relative to another element.

Headless mode or screen resolution, timing issues, environment data, missing dependencies, browser–driver version mismatch or parallel conflicts. Check logs and failure screenshots and make waits robust.

A helper that initialises @FindBy elements lazily using initElements; some teams skip it in favour of plain By locators.

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.

ArrayList has fast random access and slower inserts in the middle; LinkedList has fast inserts and deletes but slow access by index.

Set window size explicitly, use proper waits, check animations and viewport differences, and capture screenshots and logs to find timing issues.

String is immutable — every change creates a new object. StringBuilder is mutable and faster for repeated changes (not thread-safe; StringBuffer is).

Use then().time(lessThan(2000L)) and then().header("Content-Type", containsString("json")) along with body assertions.

Use TestNG parallel="methods | classes | tests" with thread-count, keep WebDriver in a ThreadLocal, and use Selenium Grid or a cloud grid for multiple browsers.

A try block that automatically closes resources such as file readers or streams, preventing leaks without a finally block.

id, name, className, tagName, linkText, partialLinkText, CSS selector and XPath. Prefer stable ids or CSS, using XPath when needed.

Classes such as Integer and Double that wrap primitive types as objects, needed for collections and for parsing text from web elements.

Implicit, explicit (WebDriverWait with ExpectedConditions) and fluent waits; avoid mixing implicit and explicit waits and never rely on Thread.sleep.

Continuous Integration builds and tests every commit, and Continuous Delivery ships automatically. Automated tests give fast feedback and gate releases.

Absolute starts from the root (/html/...) and breaks easily; relative starts anywhere with // and is more stable, for example //input[@id='email'].

Mouse and keyboard actions such as hover, drag and drop, double click, right click and key combinations, built with moveToElement(...).perform().

Verifying that a provider and consumer agree on request and response formats, using tools like Pact, to catch breaking changes early.

== compares references (or primitive values); equals() compares content when overridden, as in String.

Automate stable, repetitive, high-risk and data-heavy flows (smoke, regression). Skip one-time tests, frequently changing UI and checks needing human judgement. Compare run frequency × manual time with build and maintenance cost.

An API client. Add tests in JavaScript, use environments and collections, and run them with Newman in a CI pipeline.

Keep credentials in external data, parameterise the test with a data provider, reuse a login method in a page class, and clear sessions between roles.

driver.switchTo().alert() lets you accept, dismiss, read text or send keys. Browser windows are handled with window handles.

Stabilise waits and data, isolate tests, use retries cautiously, quarantine unstable tests, run in consistent containers and track flaky rates.

close() closes the current window; quit() closes all windows and ends the driver session.

200 OK, 201 Created, 400 bad request, 401 unauthenticated, 403 forbidden, 404 not found and 500 server error.

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.

It runs tests in parallel across multiple machines and browsers using a hub and nodes, cutting execution time and increasing browser coverage.

A test framework offering annotations, grouping, prioritisation, parallel runs, data providers and reports, which structure and scale Selenium tests.

Use external files or APIs and database setup scripts, generate unique data per run, and clean up afterwards so tests stay independent.

Cast the driver to JavascriptExecutor and use executeScript, for example to scroll into view or click hidden elements.

A scripted or declarative Jenkinsfile that defines stages such as build, test and deploy as code stored with the project.

200 OK, 201 Created, 204 No Content, 400 Bad Request, 401 Unauthorized, 403 Forbidden, 404 Not Found, 500 Internal Server Error.

Use headers such as Bearer tokens, basic auth, API keys or OAuth flows; fetch a token in a setup step and reuse it.

Docker packages tools in containers so tests run identically everywhere; Selenium Grid and browsers can be started quickly in containers.

A lightweight text format of key-value pairs and arrays used in API requests and responses, validated field by field in tests.

Get getWindowHandles(), loop to find the target, and call driver.switchTo().window(handle); switch back using the stored parent handle.

Keep URLs and credentials in per-environment config files or variables, choose with a command-line parameter and never hard-code secrets.

One interface, many forms. WebDriver driver = new ChromeDriver() lets the same test code run on any browser class that implements WebDriver.

Encapsulation, inheritance, polymorphism and abstraction. Testers use them to build reusable page classes, base tests and utility libraries.

getText returns visible inner text; getAttribute returns an HTML attribute or property such as value, href or class.

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.

Use mocks or stubs such as WireMock to simulate the dependency and test your service in isolation.

Comparable defines the natural order inside the class (compareTo); Comparator defines custom orders externally (compare), useful for sorting test data in several ways.

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.

Re-locate the element after the DOM refreshes, use explicit waits for the refreshed element, don't keep element references for long, or wrap the action in retry logic.

//button[normalize-space()='Login'] //button[contains(text(),'Login')]

It uses the key's hashCode to find a bucket and equals to resolve collisions, giving O(1) average lookups; Java 8 converts long buckets into trees.

An authorisation framework where a client obtains an access token from an auth server and sends it as a Bearer token; tests fetch and reuse the token in setup.

Create a job or pipeline that checks out code, runs mvn test, publishes reports and triggers on commits or schedules.
