Baker Hughes QA Engineer Interview Questions and Answers

My test automation framework is a modular, scalable solution that enhances testing efficiency and reliability across applications.

• Utilizes Selenium WebDriver for browser automation, allowing for cross-browser testing.

• Incorporates TestNG for test management, enabling parallel execution and detailed reporting.

• Employs Page Object Model (POM) design pattern to enhance code reusability and maintainability.

• Integrates with CI...read more

OOP concepts like encapsulation and inheritance enhance test automation frameworks for better maintainability and scalability.

• Encapsulation: Wrapping data and methods in classes. Example: A 'TestCase' class that contains test steps and results.

• Inheritance: Creating a base class for common functionalities. Example: 'BaseTest' class that other test classes extend.

• Polymorphism: Using a single interface for different data ...read more

RTM stands for Requirements Traceability Matrix, a tool used to ensure all requirements are met in software development.

• RTM links requirements to their corresponding test cases, ensuring coverage.

• It helps in tracking changes in requirements throughout the project lifecycle.

• Example: If a requirement changes, RTM shows which test cases need updates.

• RTM aids in identifying gaps in testing and ensures all requirements are

Static binding occurs at compile time, while dynamic binding happens at runtime in Java.

• Static binding is resolved during compile time, e.g., method overloading.

• Dynamic binding is resolved during runtime, e.g., method overriding.

• Static binding is faster as it doesn't involve runtime overhead.

• Dynamic binding allows for polymorphism, enabling flexible code behavior.

Abstract classes and interfaces are key concepts in Java for defining abstract types and enforcing contracts for classes.

• An abstract class can have both abstract methods (without implementation) and concrete methods (with implementation).

• An interface can only have abstract methods (prior to Java 8) and default methods (from Java 8 onwards).

• A class can extend only one abstract class but can implement multiple interfaces...read more

Git commands are essential for version control, enabling collaboration and tracking changes in code repositories.

• git init: Initializes a new Git repository in the current directory.

• git clone <repository>: Creates a local copy of a remote repository.

• git add <file>: Stages changes to be committed.

• git commit -m 'message': Records the staged changes with a descriptive message.

• git push: Uploads local commits to ...read more

PUT replaces a resource, while PATCH updates a resource partially.

• PUT is idempotent; multiple identical requests have the same effect as a single request.

• PATCH is not necessarily idempotent; repeated requests may yield different results.

• Example of PUT: Updating a user's profile by sending the entire profile data.

• Example of PATCH: Updating just the user's email address without affecting other fields.
