Database testing ensures data integrity, accuracy, and performance in applications by validating database operations and structures.

• Verify data integrity by checking for consistency between the database and application layers.

• Use tools like SQL Server Management Studio or Oracle SQL Developer for executing queries and validating results.

• Check for data accuracy by comparing data in the database with expected results from business requirements.

• Perform performance testing to ens...read more

API is a set of protocols for building software applications; API testing ensures these interfaces function correctly.

• API (Application Programming Interface) allows different software systems to communicate.

• API Testing involves verifying the functionality, reliability, performance, and security of APIs.

• Common tools for API Testing include Postman, SoapUI, and JMeter.

• API testing is typically performed at the service layer, independent of the user interface.

Use SQL query to compare two tables and fetch records based on condition

• Use JOIN clause to compare two tables

• Add a WHERE clause to specify the condition for fetching records

• Select the desired columns from the tables

API testing verification involves checking responses, status codes, and data integrity to ensure functionality and reliability.

• Check HTTP status codes: Ensure the API returns the correct status code (e.g., 200 for success, 404 for not found).

• Validate response structure: Confirm that the response body matches the expected JSON/XML schema.

• Test data integrity: Verify that the data returned by the API is accurate and consistent with the database.

• Check error handling: Send invalid...read more

Integration and end-to-end testing focus on different testing scopes, while smoke and sanity testing assess build stability and functionality.

• Integration Testing: Tests interactions between integrated components or systems. Example: Testing a payment gateway with an e-commerce platform.

• End-to-End Testing: Validates the entire application flow from start to finish. Example: Testing user registration, login, and purchase processes.

• Smoke Testing: A preliminary test to check if t...read more

Creating test scripts from user stories ensures comprehensive testing aligned with user requirements.

• Identify acceptance criteria from the user story. Example: 'As a user, I want to reset my password.'

• Define test cases based on user actions. Example: 'Verify that the reset password link is sent to the user's email.'

• Consider edge cases. Example: 'What happens if the email is not registered?'

• Map test scripts to user story features. Example: 'Test script for sending email should...read more

The Bug Life Cycle outlines the stages of a bug from discovery to closure, while various testing types ensure software quality.

• 1. Bug Life Cycle: Stages include New, Assigned, Open, Fixed, Retested, and Closed.

• 2. Unit Testing: Tests individual components for functionality, e.g., testing a single function in isolation.

• 3. Integration Testing: Ensures combined components work together, e.g., testing a database connection with an API.

• 4. System Testing: Validates the complete and ...read more

Error codes 401 and 404 indicate authentication issues and resource not found in API testing.

• 401 Unauthorized: Indicates that the request requires user authentication. Example: Accessing a protected resource without valid credentials.

• 404 Not Found: Indicates that the server can't find the requested resource. Example: Requesting a URL that doesn't exist on the server.

SDLC stands for Software Development Life Cycle, which is a process used by software development teams to design, develop, test, and deploy high-quality software.

• SDLC is a structured process that divides software development into distinct phases.

• Common phases of SDLC include planning, analysis, design, implementation, testing, and maintenance.

• Each phase has specific goals and deliverables that must be completed before moving on to the next phase.

• SDLC helps ensure that softwar...read more

Excel me 'ADD' formula ka istemal numbers ko jodne ke liye hota hai, jaise =A1 + A2 ya =SUM(A1:A10).

• Basic addition: =A1 + A2 (A1 aur A2 ke values ko jodta hai).

• Using SUM function: =SUM(A1:A10) (A1 se A10 tak ke cells ko jodta hai).

• Adding multiple numbers: =SUM(1, 2, 3) (1, 2, aur 3 ko jodta hai).

• Adding non-contiguous cells: =SUM(A1, A3, A5) (A1, A3, aur A5 ke values ko jodta hai).

Testing is the process of evaluating a system or software to identify defects or errors.

• Testing involves executing a system or software with the intention of finding defects.

• It is done to ensure that the system meets the specified requirements and functions as expected.

• Testing can be performed at various levels such as unit testing, integration testing, and system testing.

• Different testing techniques like functional testing, performance testing, and security testing are used....read more
