/**
|
|
* Journey Test: Coverage Analysis Workflow
|
|
*
|
|
* Tests the end-to-end coverage analysis workflow using O(log n) gap detection
|
|
* with Johnson-Lindenstrauss algorithm and risk-based prioritization.
|
|
*
|
|
* Purpose: Verify that the coverage analyzer agent can:
|
|
* 1. Analyze coverage data with Johnson-Lindenstrauss algorithm
|
|
* 2. Identify gaps efficiently (< 1 second for 10k LOC)
|
|
* 3. Prioritize gaps by risk (complexity, change frequency)
|
|
* 4. Generate specific test recommendations
|
|
* 5. Store analysis in database
|
|
* 6. Visualize gaps in report format
|
|
*
|
|
* Validation: Uses REAL database interactions (SwarmMemoryManager), not mocks.
|
|
* Focus: USER-FACING behavior, not implementation details.
|
|
*
|
|
* @see Issue #103 - Test Suite Migration: Phase 1 Journey Tests
