Mithi Software Technologies Automation Testing Interview Questions and Answers

Xpath for an Anchor tag in Automation Testing

• Use the 'a' tag in the Xpath expression to target anchor tags

• Use '@href' attribute to specify the link of the anchor tag

• Example: //a[@href='https://www.example.com']

Challenges faced in automation project and how they were overcome

• Lack of skilled resources - Conducted training sessions to upskill team members

• Unstable test environment - Implemented robust error handling mechanisms

• Changing requirements - Utilized agile methodologies to adapt quickly

• Integration issues with third-party tools - Collaborated with vendors for solutions

Selenium Architecture is a framework that consists of different components for automated testing of web applications.

• Selenium WebDriver: It is the core component that allows interaction with web elements.

• Selenium Grid: It enables parallel execution of tests across different browsers and environments.

• Selenium IDE: It is a record and playback tool for creating test scripts.

• Selenium RC (Remote Control): It is the predeces...read more

Yes, I have faced synchronization problems while automating tests.

• Yes, I have encountered synchronization issues when elements load at different speeds on a webpage.

• To overcome this, I have used explicit waits in Selenium to wait for specific conditions before proceeding with the test.

• I have also used implicit waits to set a default waiting time for the elements to load.

• In some cases, I have used Thread.sleep() to paus...read more

Other exceptions handled in automation testing besides NoSuchElementException

• ElementNotVisibleException - when element is present in DOM but not visible on the page

• StaleElementReferenceException - when element is no longer attached to the DOM

• TimeoutException - when a command does not complete in a specific time frame

• NoSuchWindowException - when the window target to be switched doesn't exist

• InvalidElementStateException ...read more

OOPS concepts are fundamental principles of Object-Oriented Programming, including inheritance, encapsulation, polymorphism, and abstraction.

• Inheritance: Allows a class to inherit properties and behavior from another class.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Polymorphism: Ability to present the same interface for different data types.

• Abstraction: Hiding the complex imple...read more

Relative xpath is based on the current position of an element, while absolute xpath starts from the root element.

• Relative xpath is shorter and less prone to breaking with changes in the DOM structure.

• Absolute xpath is longer and more specific, starting from the root element of the HTML document.

• Relative xpath is preferred for dynamic web elements, while absolute xpath is more suitable for static elements.

• Example: Relat...read more

Java program to reverse a string

• Create a StringBuilder object

• Use the reverse() method to reverse the string

• Convert the StringBuilder object back to a string

A framework is a set of guidelines, coding standards, concepts, and practices that provide structure and support for automated testing.

• Framework helps in organizing and executing automated tests efficiently.

• Common frameworks include Data-Driven, Keyword-Driven, Hybrid, and Behavior-Driven Development (BDD).

• In my project, I have worked on a Data-Driven framework where test data is separated from test scripts for easy ma

TestNG provides the ability to re-run failed test cases using the 'retryAnalyzer' feature.

• Implement a custom 'IRetryAnalyzer' class to define the retry logic for failed test cases.

• Specify the 'retryAnalyzer' attribute in the @Test annotation with the custom retry analyzer class.

• Set the 'retryAnalyzer' attribute to the custom class name in the testng.xml file to apply the retry logic globally.

• Failed test cases will be a...read more

Interface in Java is a reference type in Java, similar to a class, that can contain only constants, method signatures, default methods, static methods, and nested types.

• An interface is a blueprint of a class that can have abstract methods and constants.

• Interfaces are used to achieve abstraction and multiple inheritance in Java.

• Classes can implement multiple interfaces but can only extend one class.

• Example: interface Sh...read more

Fluent wait, implicit wait, and explicit wait are different types of wait strategies used in automation testing to handle synchronization issues.

• Fluent wait is a dynamic wait mechanism in Selenium WebDriver that waits for a condition to be true with a specified polling frequency.

• Implicit wait is a global wait applied to all elements in the WebDriver instance, allowing a certain amount of time for elements to load befor...read more

Yes, TestNG supports crossbrowser testing by allowing the execution of test cases on multiple browsers in parallel.

• TestNG allows the use of @Parameters annotation to pass browser type as a parameter to test methods.

• TestNG can be integrated with Selenium WebDriver to run tests on different browsers like Chrome, Firefox, and Safari.

• TestNG provides the flexibility to run tests in parallel on multiple browsers for faster e
