System Testing Overview

System Testing

• Definition:

  • System testing is a level of software testing where the complete and integrated software product is evaluated.

• Purpose:

  • To validate the end-to-end system specifications.
  • To ensure that the system meets the defined requirements and is ready for deployment.

• Types of System Testing:

  1. Functional Testing:
     • Validates the application's functionalities against requirements.
  2. Non-functional Testing:
     • Assesses performance, usability, reliability, etc.
  3. Security Testing:
     • Identifies vulnerabilities, threats, and risks within the application.
  4. Performance Testing:
     • Tests the responsiveness and stability under load.
  5. Compatibility Testing:
     • Ensures the software works across different devices, OS, browsers, etc.

• System Testing Process:

  1. Test Planning:
     • Define the scope, objectives, resources, and schedule.
  2. Test Case Design:
     • Create detailed test cases based on requirements.
  3. Test Execution:
     • Execute the test cases and record the results.
  4. Defect Reporting:
     • Log any defects discovered and track them until resolved.
  5. Test Closure:
     • Evaluate cycle completion criteria and provide test summary reports.

• Key Principles:

  • Comprehensive Testing: All aspects of the application should be tested.
  • Test Environment: Must replicate production settings.
  • Regression Testing: Check for new bugs due to changes.

• Importance:

  • Ensures software quality and reliability.
  • Helps identify issues before the product goes live.
  • Reduces maintenance costs by discovering defects early.

• Best Practices:

  • Involve stakeholders for requirement validation.
  • Automate repetitive tests where possible.
  • Maintain clear and detailed documentation.
  • Perform testing in various configurations and environments.
