Hard assert stops the execution of the test case if it fails, while soft assert continues the execution and logs the failure.
Hard assert is used when the failure of a particular step makes the further steps irrelevant.
Soft assert is used when you want to continue with the test case execution even if some steps fail.
Hard assert is implemented using 'assert' keyword in testing frameworks like TestNG or JUnit.
Soft assert ...
Annotations in Selenium WebDriver are used to provide additional information about the test methods.
Annotations help in organizing and managing test cases

In my project, I perform validations such as data completeness, data accuracy, data transformation, and data integrity checks.
Data completeness checks to ensure all required fields are populated
Data accuracy checks to verify the correctness of data
Data transformation checks to validate the transformation rules are applied correctly
Data integrity checks to maintain data consistency and reliability
Star Schema is a type of database schema where a central fact table is connected to multiple dimension tables. Snowflake Schema is a normalized form of Star Schema where dimension tables are further normalized into sub-dimension tables.

Fact tables contain quantitative data while dimension tables contain descriptive attributes.
Fact tables store measurable, quantitative data such as sales revenue or quantity sold
Dimension tables store descriptive attributes related to the data in the fact table, such as product name or customer details
Fact tables are typically normalized while dimension tables are denormalized for easier querying
Example: In a sales dat...

API testing is a type of software testing that involves testing APIs directly to ensure they meet functionality, reliability, performance, and security requirements.
API testing involves testing the functionality, reliability, performance, and security of APIs.
It focuses on verifying the communication and data exchange between different software systems.
API testing can be done at different levels such as unit testing, i...
Post is used to create a new resource, while patch is used to update an existing resource.
Post is used to create a new resource in the server.
Patch is used to update an existing resource in the server.
Post request typically includes all the data needed to create the resource, while patch request only includes the data that needs to be updated.
Post requests are idempotent, meaning multiple identical requests will have t...
Priority and severity are used to classify the impact and importance of a defect in software testing.
Priority determines the order in which defects should be fixed, based on business needs.
Severity indicates the impact of a defect on the system or users.
Priority is usually set by the product owner or business stakeholders.
Severity is typically determined by the testing team based on the impact on functionality.
Examples...
I was interviewed in Nov 2024.
HashMap is non-synchronized and allows null values, while Hashtable is synchronized and does not allow null values.
HashMap is non-synchronized and not thread-safe, while Hashtable is synchronized and thread-safe.
HashMap allows null values for both key and value, while Hashtable does not allow null keys or values.
HashMap is faster than Hashtable as it is non-synchronized.
HashMap is part of the Java Collections Framework
Types of exceptions in Selenium include NoSuchElementException, ElementNotVisibleException, StaleElementReferenceException, TimeoutException, and WebDriverException.
NoSuchElementException: Thrown when an element could not be found in the DOM.
ElementNotVisibleException: Thrown when an element is present in the DOM but not visible.
StaleElementReferenceException: Thrown when an element is no longer attached to the DOM.

Abstract class can have both abstract and non-abstract methods, while interface can only have abstract methods.
Abstract class can have constructors, fields, and non-abstract methods, while interface cannot.
A class can implement multiple interfaces but can only inherit from one abstract class.
Abstract classes are used to define a common behavior for subclasses, while interfaces are used to define a contract for classes ...

Project architecture refers to the overall structure of a software project, including components, modules, and their interactions.
Project architecture defines how different components of a software project are organized and interact with each other.
It includes the high-level design of the system, such as the database structure, data flow, and integration points.
Project architecture also involves decisions on technologi...
Challenges in ETL testing include data quality issues, complex transformations, and handling large volumes of data.
Data quality issues such as missing or incorrect data can impact testing results
Complex transformations can be difficult to validate and may lead to errors in the ETL process
Handling large volumes of data can slow down testing processes and require efficient testing strategies
Roles and responsibilities refer to the tasks and duties assigned to an individual within a specific job or position.
Roles define the position or job title of an individual within an organization.
Responsibilities outline the specific tasks, duties, and expectations associated with that role.
Roles and responsibilities help clarify expectations, define boundaries, and ensure accountability.
Examples include testing data e...
Use a dictionary to find duplicate values in an array of strings in Python.
Create an empty dictionary to store the count of each string in the array.
Iterate through the array and for each string, check if it exists in the dictionary. If it does, increment the count. If not, add it to the dictionary with a count of 1.
After iterating through the array, check the dictionary for any strings with a count greater than 1. The

A deferred bug is a bug that is not fixed immediately but is scheduled to be fixed in a future release.
Deferred bugs are usually lower priority bugs that do not impact the core functionality of the system.
These bugs are documented and tracked for resolution in a later release.
Examples of deferred bugs include cosmetic issues, minor usability problems, or non-critical functionality issues.
Use SQL query with ORDER BY and LIMIT to get 4th highest row based on a column
Use ORDER BY clause to sort the column in descending order

Example: SELECT * FROM table_name ORDER BY column_name DESC LIMIT 1 OFFSET 3
Oops concepts refer to Object-Oriented Programming principles such as 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 implementation det
