# Phase 2: Test-Cycle Execution

Dynamic test-fix execution with **adaptive task generation** based on runtime analysis. Iterative fix cycles until test pass rate >= 95% or max iterations reached. All agent interactions use spawn_agent → wait → close_agent lifecycle.

**vs Standard Execute**:
- **Standard**: Pre-defined tasks → Execute sequentially → Done
- **Test-Cycle**: Initial tasks → **Test → Analyze failures → Generate fix tasks → Fix → Re-test** → Repeat until pass

## Agent Roles

| Agent | Responsibility |
|-------|---------------|
| **Orchestrator** | Loop control, strategy selection, pass rate calculation, threshold decisions |
| **@cli-planning-agent** | CLI analysis (Gemini/Qwen/Codex), root cause extraction, task generation, affected test detection |
| **@test-fix-agent** | Test execution, code fixes, criticality assignment, result reporting |

## Core Responsibilities

### Orchestrator
- Session discovery, task queue management
- Pass rate calculation: `(passed / total) * 100` from test-results.json
- Criticality assessment (high/medium/low)
- Strategy selection based on context
- **Runtime Calculations** (from iteration-state.json):
  - Current iteration: `iterations.length + 1`
  - Stuck tests: Tests appearing in `failed_tests` for 3+ consecutive iterations
  - Regression: Compare consecutive `pass_rate` values (>10% drop)
  - Max iterations: Read from `task.meta.max_iterations`
- Iteration control (max 10, default)
- CLI tool fallback chain: Gemini → Qwen → Codex
- Progress tracking
- Session auto-complete (pass rate >= 95%)
- **Explicit Lifecycle**: Always close_agent after wait completes

### @cli-planning-agent
- Execute CLI analysis with bug diagnosis template
- Parse output for root causes and fix strategy
- Generate IMPL-fix-N.json task definition
- Detect affected tests for progressive testing
- Save: analysis.md, cli-output.txt

### @test-fix-agent
- Execute tests, save results to test-results.json
- Apply fixes from task.context.fix_strategy
- Assign criticality to failures
- Update task status

## Intelligent Strategy Engine

**Auto-selects optimal strategy based on iteration context:**

| Strategy | Trigger | Behavior |
|----------|---------|----------|
| **Conservative** | Iteration 1-2 (default) | Single targeted fix, full validation |
| **Aggressive** | Pass rate >80% + similar failures | Batch fix related issues |
| **Surgical** | Regression detected (pass rate drops >10%) | Minimal changes, rollback focus |

**Selection Logic** (in orchestrator):
```javascript
if (iteration <= 2) return "conservative";
if (passRate > 80 && failurePattern.similarity > 0.7) return "aggressive";
if (regressionDetected) return "surgical";
return "conservative";
```

**Integration**: Strategy passed to @cli-planning-agent in prompt for tailored analysis.

## Progressive Testing

**Runs affected tests during iterations, full suite only for final validation.**

**How It Works**:
1. @cli-planning-agent analyzes fix_strategy.modification_points
2. Maps modified files to test files (via imports + integration patterns)
3. Returns `affected_tests[]` in task JSON
4. @test-fix-agent runs: `npm test -- ${affected_tests.join(' ')}`
5. Final validation: `npm test` (full suite)


**Benefits**: 70-90% iteration speed improvement, instant feedback on fix effectiveness.

## Agent Invocation Template

**@cli-planning-agent** (failure analysis):
```javascript
// Spawn agent for failure analysis
const analysisAgentId = spawn_agent({

    - Stuck Tests: ${stuckTests} (calculated from iterations[].failed_tests history)

    ## CLI Configuration
    - Tool Priority: gemini & codex
    - Template: 01-diagnose-bug-root-cause.txt
    - Timeout: 2400000ms

    ## Expected Deliverables
    1. Task JSON: ${session.task_dir}/IMPL-fix-${N}.json

**Tool Details**:
1. **Gemini** (primary): `gemini-2.5-pro`
2. **Qwen** (fallback): `coder-model`
3. **Codex** (fallback): `gpt-5.1-codex`

**When to Fallback**: HTTP 429, timeout, analysis quality degraded

```

## Iteration State JSON

**Purpose**: Persisted state machine for iteration loop - enables Resume and historical analysis.

```json
{
  "current_task": "IMPL-002",
  "selected_strategy": "aggressive",
  "next_action": "execute_fix_task",
  "iterations": [
    {
      "iteration": 1,
      "pass_rate": 70,
      "strategy": "conservative",
      "failed_tests": ["test_auth_flow", "test_user_permissions"]
    },
    {
      "iteration": 2,
      "pass_rate": 82,
      "strategy": "conservative",
      "failed_tests": ["test_user_permissions", "test_token_expiry"]
    },
    {
      "iteration": 3,
      "pass_rate": 89,
      "strategy": "aggressive",
      "failed_tests": ["test_auth_edge_case"]
    }
  ]
}
```

**Field Descriptions**:
- `current_task`: Pointer to active task (essential for Resume)
- `selected_strategy`: Current iteration strategy (runtime state)
- `next_action`: State machine next step (`execute_fix_task` | `retest` | `complete`)
- `iterations[]`: Historical log of all iterations (source of truth for trends)

## Completion Conditions

**Full Success**:
- All tasks completed
- Pass rate === 100%
- Action: Auto-complete session

**Partial Success**:
- All tasks completed
- Pass rate >= 95% and < 100%
- All failures are "low" criticality
- Action: Auto-approve with review note

**Failure**:
- Max iterations (10) reached without 95% pass rate
- Pass rate < 95% after max iterations
- Action: Generate failure report, mark blocked, return to user

## Error Handling

| Scenario | Action |
|----------|--------|
| Test execution error | Log, retry with error context |
| CLI analysis failure | Fallback: Gemini → Qwen → Codex → manual |
| Agent execution error | Save state, close_agent, retry with simplified context |
| Max iterations reached | Generate failure report, mark blocked |
| Regression detected | Rollback last fix, switch to surgical strategy |
| Stuck tests detected | Continue with alternative strategy, document in failure report |

**CLI Fallback Triggers** (Gemini → Qwen → Codex → manual):

Fallback is triggered when any of these conditions occur:

1. **Invalid Output**:
   - CLI tool fails to generate valid `IMPL-fix-N.json` (JSON parse error)
   - Missing required fields: `fix_strategy.modification_points` or `fix_strategy.affected_tests`

2. **Low Confidence**:
   - `fix_strategy.confidence_score < 0.4` (indicates uncertain analysis)

3. **Technical Failures**:
   - HTTP 429 (rate limit) or 5xx errors
   - Timeout (exceeds 2400000ms / 40min)
   - Connection errors

4. **Quality Degradation**:
   - Analysis report < 100 words (too brief, likely incomplete)
   - No concrete modification points provided (only general suggestions)
   - Same root cause identified 3+ consecutive times (stuck analysis)

**Fallback Sequence**:
- Try primary tool (Gemini)
- If trigger detected → Try fallback (Qwen)
- If trigger detected again → Try final fallback (Codex)
- If all fail → Mark as degraded, use basic pattern matching from fix-history.json, notify user

**Lifecycle Error Handling**:
```javascript
try {
  const agentId = spawn_agent({ message: "..." });
  const result = wait({ ids: [agentId], timeout_ms: 2400000 });
  // ... process result ...
  close_agent({ id: agentId });
} catch (error) {
  if (agentId) close_agent({ id: agentId });
  // Save state for resume capability
  throw error;
}
```

## Progress Tracking Pattern

```javascript
[
  {
    content: "Execute IMPL-001: Generate tests [code-developer]",
    status: "completed"
  },
  {
    content: "Execute IMPL-002: Test & Fix Cycle [ITERATION]",
    status: "in_progress"
  },
  {
    content: "  → Iteration 1: Initial test (pass: 70%, conservative)",
    status: "completed"
  },
  {
    content: "  → Iteration 2: Fix validation (pass: 82%, conservative)",
    status: "completed"
  },
  {
    content: "  → Iteration 3: Batch fix auth (pass: 89%, aggressive)",
    status: "in_progress"
  }
]
```

**Update Rules**:
- Add iteration item with: strategy, pass rate
- Mark completed after each iteration
- Update parent task when all complete

## Commit Strategy

**Automatic Commits** (orchestrator-managed):

The orchestrator automatically creates git commits at key checkpoints to enable safe rollback:

1. **After Successful Iteration** (pass rate increased):
   ```bash
   git add .
   git commit -m "test-cycle: iteration ${N} - ${strategy} strategy (pass: ${oldRate}% → ${newRate}%)"
   ```

2. **Before Rollback** (regression detected):
   ```bash
   # Current state preserved, then:
   git revert HEAD
   git commit -m "test-cycle: rollback iteration ${N} - regression detected (pass: ${newRate}% < ${oldRate}%)"
   ```

**Commit Content**:
- Modified source files from fix application
- Updated test-results.json, iteration-state.json
- Excludes: temporary files, logs

**Benefits**:
- **Rollback Safety**: Each iteration is a revert point
- **Progress Tracking**: Git history shows iteration evolution
- **Audit Trail**: Clear record of which strategy/iteration caused issues
- **Resume Capability**: Can resume from any checkpoint

**Note**: Final session completion creates additional commit with full summary.

## Post-Completion Expansion

完成后询问用户是否扩展为issue(test/enhance/refactor/doc)，选中项创建新 issue: `"{summary} - {dimension}"`

## Best Practices

1. **Default Settings Work**: 10 iterations sufficient for most cases
2. **Automatic Commits**: Orchestrator commits after each successful iteration - no manual intervention needed
3. **Trust Strategy Engine**: Auto-selection based on proven heuristics
4. **Monitor Logs**: Check `.process/iteration-N-analysis.md` for CLI analysis insights
5. **Progressive Testing**: Saves 70-90% iteration time automatically
6. **Always Close Agents**: Ensure close_agent is called after every wait completes, including error paths
