Personalization Features Testing

🟡Intermediate

This document outlines the testing procedures for personalization features with different student profiles. The tests validate that content adapts appropriately to different skill levels and learning preferences.

Test Profiles​

Profile 1: Beginner Student​

{
  "id": "student-beginner-001",
  "skillLevel": "beginner",
  "preferredLearningPath": "theoretical",
  "personalizationSettings": {
    "difficultyFilter": "beginner",
    "learningPath": "theoretical",
    "showAdvancedContent": false,
    "showSimplifiedExplanations": true,
    "includeAdditionalExamples": true,
    "highlightKeyConcepts": true
  }
}

Expected Behavior:

  • Content filtered to beginner level only
  • Simplified explanations displayed
  • Additional examples included
  • Key concepts highlighted
  • Advanced content hidden
  • Theoretical focus emphasized

Profile 2: Intermediate Student​

{
  "id": "student-intermediate-002",
  "skillLevel": "intermediate",
  "preferredLearningPath": "mixed",
  "personalizationSettings": {
    "difficultyFilter": "intermediate",
    "learningPath": "mixed",
    "showAdvancedContent": false,
    "showSimplifiedExplanations": false,
    "includeAdditionalExamples": true,
    "highlightKeyConcepts": true
  }
}

Expected Behavior:

  • Content filtered to beginner and intermediate levels
  • Moderate level of detail
  • Some additional examples
  • Concepts highlighted appropriately
  • Advanced content hidden
  • Mixed theoretical and practical approach

Profile 3: Advanced Student​

{
  "id": "student-advanced-003",
  "skillLevel": "advanced",
  "preferredLearningPath": "practical",
  "personalizationSettings": {
    "difficultyFilter": "advanced",
    "learningPath": "practical",
    "showAdvancedContent": true,
    "showSimplifiedExplanations": false,
    "includeAdditionalExamples": false,
    "highlightKeyConcepts": true
  }
}

Expected Behavior:

  • All content levels accessible
  • Advanced content displayed
  • Minimal simplified explanations
  • Focus on practical implementation
  • Advanced examples and challenges included

Test Scenarios​

Scenario 1: Content Filtering​

Objective: Verify that content is properly filtered based on difficulty level.

Steps:

  1. Load the textbook with Beginner profile
  2. Navigate to Chapter 1
  3. Verify only beginner-appropriate content is displayed
  4. Repeat with Intermediate and Advanced profiles

Expected Results:

  • Beginner profile: Only basic concepts and simplified explanations
  • Intermediate profile: Moderate complexity content
  • Advanced profile: All content including advanced sections

Scenario 2: Learning Path Adaptation​

Objective: Verify that content adapts to preferred learning path.

Steps:

  1. Load textbook with "theoretical" learning path
  2. Navigate to ROS 2 concepts section
  3. Verify theoretical explanations are emphasized
  4. Switch to "practical" learning path
  5. Verify practical examples are emphasized

Expected Results:

  • Theoretical path: More mathematical explanations, algorithmic focus
  • Practical path: More implementation details, hands-on examples
  • Mixed path: Balanced approach

Scenario 3: Progress Tracking​

Objective: Verify that progress is tracked correctly per profile.

Steps:

  1. Complete Chapter 1 with Beginner profile
  2. Verify progress is recorded
  3. Switch to Intermediate profile
  4. Verify progress is appropriately tracked

Expected Results:

  • Progress is maintained per profile
  • Personalization settings persist between sessions
  • Cross-profile contamination does not occur

Scenario 4: Component Functionality​

Objective: Verify that personalization components function correctly.

Components to Test:

  • DifficultyFilter component
  • PersonalizationPanel component
  • ProgressTracker component
  • LearningPathSelector component

Steps:

  1. Verify each component renders without errors
  2. Verify interactive elements function correctly
  3. Verify state management works properly
  4. Verify responsive design works on different screen sizes

Expected Results:

  • All components render correctly
  • Interactive elements respond to user input
  • State persists appropriately
  • Components are responsive and accessible
