Software Testing

Software Testing is the process of evaluating a software application to ensure it meets specified requirements, functions as expected, and is free from defects. It plays a critical role in delivering high-quality software by identifying issues before deployment.

Here’s a breakdown of key aspects:

Types of Software Testing
  1. Functional Testing:

    • Ensures the software performs according to specified requirements.
    • Includes Unit Testing, Integration Testing, System Testing, and User Acceptance Testing (UAT).
  2. Non-Functional Testing:

    • Focuses on performance, usability, reliability, scalability, and other quality attributes.
    • Examples include Performance Testing, Security Testing, Usability Testing, and Compatibility Testing.
  3. Manual Testing:

    • Conducted by human testers without the use of automation tools.
    • Effective for exploratory, usability, and ad-hoc testing.
  4. Automated Testing:

    • Uses tools like Selenium, JUnit, or TestNG to execute test cases automatically.
    • Ideal for regression, performance, and load testing.
Phases of Software Testing
  1. Requirement Analysis: Understanding the software requirements to design test cases.
  2. Test Planning: Defining the testing approach, resources, schedule, and tools.
  3. Test Case Development: Writing detailed test cases and preparing test data.
  4. Environment Setup: Preparing the test environment to execute test cases.
  5. Test Execution: Running test cases and logging defects.
  6. Defect Reporting and Tracking: Identifying, documenting, and tracking bugs to resolution.
  7. Test Closure: Analyzing test results, documenting findings, and archiving test artifacts.
