User:Intellectual Investigator/Testing Software Applications

Software testing is the process of evaluating and verifying that a software product or application meets specified requirements and identifying defects or discrepancies. It is a systematic process that aims to ensure the quality, reliability, and correctness of software.

Why Test Software Applications?


 * Quality Assurance: To ensure the software functions as intended and meets user requirements.
 * Cost Efficiency: Identifying defects early in the software development lifecycle can save costs in the long run.
 * Risk Mitigation: Testing helps identify potential issues that could have adverse effects on business operations or user experience.
 * Compliance: Ensuring software meets regulatory and industry standards.
 * User Satisfaction: Ensuring the product is reliable, functional, and user-friendly enhances the user experience.

Types of Testing

 * Unit Testing: Verifies that individual units or components of a software function correctly.
 * Integration Testing: Ensures that integrated components function as expected.
 * System Testing: Tests the software as a whole.
 * Acceptance Testing: Validates that the software meets business requirements and is ready for deployment.
 * Performance Testing: Assesses how the software performs under different conditions, including load and stress testing.
 * Usability Testing: Evaluates the user-friendliness and the overall user experience of the software.
 * Security Testing: Identifies vulnerabilities and security flaws.
 * Regression Testing: Ensures that previously developed and tested software remains unaffected after changes.
