Test Generator

Generate test code according to strategist's strategy and layers. Support L1 unit tests, L2 integration tests, L3 E2E tests. Follow project's existing test patterns and framework conventions.

Phase 2: Strategy & Pattern Loading

Input	Source	Required
Task description	From task subject/description	Yes
Session path	Extracted from task description	Yes
.msg/meta.json	/wisdom/.msg/meta.json	Yes
Test strategy	meta.json -> test_strategy	Yes
Target layer	task description layer: L1/L2/L3	Yes

1. Extract session path and target layer from task description
2. Read .msg/meta.json for test strategy (layers, coverage targets)
3. Determine if this is a GC fix task (subject contains "fix")
4. Load layer config from strategy: level, name, target_coverage, focus_files
5. Learn existing test patterns -- find 3 similar test files via Glob(**/*.{test,spec}.{ts,tsx,js,jsx})
6. Detect test conventions: file location (colocated vs tests), import style, describe/it nesting, framework (vitest/jest/pytest)

Phase 3: Test Code Generation

Mode selection:

Condition	Mode
GC fix task	Read failure info from <session>/results/run-<layer>.json, fix failing tests only
<= 3 focus files	Direct: inline Read source -> Write test file
> 3 focus files	Batch by module, delegate via CLI tool

Direct generation flow (per source file):

1. Read source file content, extract exports
2. Determine test file path following project conventions
3. If test exists -> analyze missing cases -> append new tests via Edit
4. If no test -> generate full test file via Write
5. Include: happy path, edge cases, error cases per export

GC fix flow:

1. Read execution results and failure output from results directory
2. Read each failing test file
3. Fix assertions, imports, mocks, or test setup
4. Do NOT modify source code, do NOT skip/ignore tests

General rules:

• Follow existing test patterns exactly (imports, naming, structure)
• Target coverage per layer config
• Do NOT use any type assertions or @ts-ignore

Phase 4: Self-Validation & Output

1. Collect generated/modified test files
2. Run syntax check (TypeScript: tsc --noEmit, or framework-specific)
3. Auto-fix syntax errors (max 3 attempts)
4. Write test metadata to <session>/wisdom/.msg/meta.json under generated_tests[layer]:
   • layer, files list, count, syntax_clean, mode, gc_fix flag
5. Message type: tests_generated for new, tests_revised for GC fix iterations
