    Study Notes

    Testing Levels

    • There are four levels of testing: Unit Testing, Integration Testing, System Testing, and Acceptance Testing.

    Unit Testing

    • Involves testing individual components or units of a software application.
    • The first level of functional testing.
    • Aims to validate unit components with their performance.

    Usability Testing

    • Usability testing measures how easy and user-friendly a software application is
    • Focuses on user's ease of use, flexibility, and ability to meet objectives
    • Recommended during initial design phase of SDLC for visibility into user expectations
    • Goals: satisfy users, identify usability errors early, and save product from failure
    • Key parameters:
      • Effectiveness: easy to learn, useful, adds value to target audience
      • Efficiency: minimal navigation, uniformity, and search options
      • Accuracy: no outdated or incorrect data, no broken links

    Integration Testing

    • Types: Incremental, Non-Incremental
    • Incremental integration testing:
      • Integrates logically related modules and tests for proper functioning
      • Early detection of defects, better collaboration, and controlled approach
      • Approaches: Top-Down, Bottom-Up, Sandwich (combination of Top-Down and Bottom-Up)
    • Top-Down integration testing:
      • Tests higher-level modules first, then lower-level modules
      • Ensures module added is a child of the previous module

    System Testing

    • Tests the system as a whole, ensuring all modules work as expected
    • Conducted after Integration Testing, focuses on overall functionality
    • Key aspects:
      • GUI Testing
      • Usability Testing
      • Functional Testing
      • Non-Functional Testing
    • Importance: delivers high-quality product, ensures customer requirements are met

    GUI Testing

    • Tests the interface of an application, including:
      • Menus, checkboxes, buttons, colors, fonts, sizes, icons, content, and images
      • Windows, Icons, Menus, Buttons, Scroll Bars, Dialog Boxes
    • GUI Testing Checklist:
      • Testing size, position, width, and height of elements
      • Testing error messages, font readability, and screen sections
      • Testing in different resolutions, alignments, and image clarity
      • Testing hyperlink colors, attractive design, disabled fields, and image size
