Automation Testing Interview Questions for Managers (₹30–40 LPA)

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.

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

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.

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

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.

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

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).

A subclass redefines a parent method. Frameworks use it to customise base behaviour, such as overriding a wait or click method in a base page class.

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

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

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

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

Behaviour-driven development writes scenarios in Given-When-Then Gherkin that map to step definitions in code, so business and QA share one language.

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

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

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.

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.

Use CSS or XPath with contains(), starts-with() or stable attributes, relative axes, or data-test attributes agreed with developers.

If the element is <input type="file">, use element.sendKeys("C:/path/file.pdf"). Use the Robot class or AutoIt only as a last resort for OS dialogs.

SOAP is a strict XML protocol with WSDL and WS-Security; REST is a lighter architectural style using HTTP and usually JSON.

A framework combining data-driven, keyword-driven and POM approaches with reporting and utilities, giving flexibility and reuse.

findElement returns the first match and throws NoSuchElementException if nothing is found. findElements returns a List (empty if nothing is found) — handy to check whether an element exists.

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

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

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

It manages dependencies through pom.xml, builds the project, runs tests with Surefire and standardises structure across teams.

Implement IRetryAnalyzer with a retry count and attach it through the test annotation or a listener to rerun flaky tests.

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.

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

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

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.

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

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.

A callback where one system sends an HTTP request to another when an event occurs. Test with a mock receiver or tools such as webhook.site and verify the payload.

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

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

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

Compare effort saved by running automated tests repeatedly against the cost of building and maintaining scripts, counting execution time, defects found earlier and release speed.

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

Implement ITestListener.onTestFailure(): File src = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE); then copy it into the reports folder.

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

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

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

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

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

switchTo().frame(index, name or element) enters the frame, and switchTo().defaultContent() returns to the main page.

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

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.

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

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