Study Notes

Software Testing Overview

  • Testers use manual interaction or execute test scripts to identify bugs and ensure software functions as intended.
  • Different testing methodologies are applied based on development models.

Testing Models

  • Waterfall Model: Formal testing occurs during a designated testing phase.
  • Incremental Model: Testing is performed at the end of each increment, with a comprehensive test at the end of the entire application.

Function Verification

  • Testing verifies that each function of the software aligns with the specifications in the requirement document.
  • Developers assess individual code units to ensure they operate correctly.

Types of Testing

  • Integration Testing: Focuses on verifying that integrated units function together without errors, emphasizing software construction and design.
  • System Testing: Involves compiling the entire software system and testing it as a complete entity to evaluate overall functionality and performance.
