Tech Mahindra Automation Test Engineer Interview Questions, Process, and Tips

Absolute Xpath starts from the root element, while relative Xpath starts from any node in the DOM structure.

• Absolute Xpath starts with a single forward slash (/) and starts selection from the root node.

• Relative Xpath starts with a double forward slash (//) and starts selection from the current node or any node in the DOM structure.

• Absolute Xpath is more brittle and prone to breaking if the structure of the page changes...read more

The return would be the number of tabs open in the browser.

• The return value would be an integer representing the count of open tabs.

• For example, if there are 5 tabs open, the return value would be 5.

Types of waits in Selenium include Implicit Wait, Explicit Wait, and Fluent Wait.

• Implicit Wait: Waits for a certain amount of time before throwing a NoSuchElementException.

• Explicit Wait: Waits for a certain condition to occur before proceeding further in the code.

• Fluent Wait: Waits for a condition to be true with a defined polling frequency.

• Example: driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

Exceptions in Selenium are errors that occur during test execution, disrupting the flow of the test script.

• Exceptions are thrown when there is an unexpected behavior in the application under test or in the test script itself.

• Common exceptions in Selenium include NoSuchElementException, ElementNotVisibleException, TimeoutException, and StaleElementReferenceException.

• Handling exceptions in Selenium can be done using try-...read more

Feature files contain high-level description of the functionality to be tested, while step definitions are the implementation of the steps in the feature file using code.

• Feature files are written in Gherkin syntax and describe the behavior of the application in plain text.

• Step definitions are written in programming languages like Java, Ruby, etc., and map the steps in the feature file to automation code.

• Feature files a...read more

Data can be input in Cucumber using feature files and step definitions.

• Data can be input in feature files using scenarios and scenario outlines

• Step definitions can be used to define the actions to be taken with the input data

• Data tables can be used in feature files to input structured data

• Examples keyword can be used in scenario outlines to provide multiple sets of input data

Test case is a set of conditions or variables under which a tester will determine whether a system under test satisfies requirements. Test plan is a document outlining the scope, approach, resources, and schedule of testing activities. Test scenarios are detailed descriptions of possible interactions with the system.

• Test case: specific conditions to be tested, expected results, steps to execute

• Test plan: overall strate...read more

Hooks in Java are methods that allow subclasses to override or extend the behavior of a superclass.

• Hooks are commonly used in frameworks like JUnit and TestNG for test automation.

• They are often used for setup and teardown operations before and after test methods.

• Examples include @Before, @After, @BeforeClass, and @AfterClass annotations in JUnit.

A constructor is a special type of method in a class that is automatically called when an object of that class is created.

• Constructors have the same name as the class they belong to

• They are used to initialize the object's state or perform any necessary setup

• Constructors can have parameters to customize the initialization process

• Example: public class Car { public Car(String color) { this.color = color; } }

Yes, a static method can be overridden in Java using the concept of method hiding.

• In Java, static methods cannot be overridden in the traditional sense like instance methods.

• When a subclass defines a static method with the same signature as a static method in the superclass, it is called method hiding.

• Method hiding does not follow polymorphism and is resolved at compile time based on the reference type.

• Example: class...read more

Yes, a static local variable can be created inside a static method.

• Yes, a static local variable can be declared inside a static method in programming languages like C++.

• Static local variables retain their values between function calls.

• Example: static void myStaticMethod() { static int count = 0; count++; }

String memory allocation is dynamic and depends on the length of the string.

• String memory allocation is dynamic and can change based on the length of the string.

• In Java, a String object is stored in the heap memory.

• Each character in a String typically takes up 2 bytes of memory.

• String objects in Java are immutable, meaning once a String object is created, it cannot be changed.

Yes, you can create a static method inside an abstract class or interface.

• Static methods can be defined in interfaces since Java 8.

• Static methods in interfaces are used for providing utility methods that are not tied to any specific instance of the interface.

• Static methods in abstract classes can be used for common functionality that does not require an instance of the class.

The parent class of Java is the Object class.

• All classes in Java are directly or indirectly derived from the Object class.

• The Object class is the root class in Java's class hierarchy.

• It provides methods that are common to all objects in Java, such as toString(), equals(), and hashCode().

Window Handles in Selenium are unique identifiers used to handle multiple browser windows in a Selenium test script.

• Window Handles are unique alphanumeric strings assigned to each browser window opened by Selenium.

• They are used to switch between different browser windows during a test script execution.

• Window Handles can be obtained using getWindowHandles() method in Selenium.

• Example: Set handles = driver.getWindowHandl
