Testing Strategy

Three-Tier Approach

We use a three-tier testing strategy optimized for different use cases:

1. Smoke Test ⚡ (CI/CD)

Purpose: Fast validation on every PR
Tests: 1 test
Time: ~30 seconds
Coverage: ~10% (basic functionality)

When to use:

  • ✅ Every PR (automated via GitHub Actions)
  • ✅ Quick sanity checks
  • ✅ CI/CD pipelines

Command:

npm run test:ci:openagent

What it tests:

  • Basic approval workflow
  • File creation
  • Minimal validation (no evaluators for speed)

2. Core Test Suite ✅ (Development)

Purpose: Comprehensive validation of critical functionality
Tests: 7 tests
Time: 5-8 minutes
Coverage: ~85% of critical functionality

When to use:

  • ✅ Prompt iteration and testing
  • ✅ Development and quick validation
  • ✅ Pre-commit hooks
  • ✅ Local testing before pushing

Command:

npm run test:core

What it tests:

  1. Approval Gate - Critical safety rule

  3. Context Loading (Multi-Turn) - Complex scenarios
  4. Stop on Failure - Error handling
  5. Simple Task - No unnecessary delegation
  6. Subagent Delegation - Proper delegation when needed
  7. Tool Usage - Best practices

Coverage breakdown:

  • ✅ All 4 critical safety rules (100%)
  • ✅ Delegation logic (simple + complex)
  • ✅ Tool usage best practices
  • ✅ Multi-turn conversations

3. Full Test Suite 🔬 (Release)

Key Features

✅ SDK-Based Execution

  • Uses official @opencode-ai/sdk for real agent interaction
  • Real-time event streaming (10+ events per test)
  • Actual session recording to disk

✅ Sequential Execution with Rate Limiting

  • Tests run one at a time (no parallel requests)
  • 3 second delay between tests
  • Prevents rate limiting on free tier

✅ Cost-Aware Testing

  • FREE by default - Uses opencode/grok-code-fast
  • Override per-test or via CLI: --model=provider/model
  • No accidental API costs during development

✅ Smart Timeout System

  • Activity monitoring - extends timeout while agent is working
  • Base timeout: 300s (5 min) of inactivity
  • Absolute max: 600s (10 min) hard limit

✅ Rule-Based Validation

  • 8 evaluators check compliance with agent rules
  • Tests behavior (tool usage, approvals) not style
  • Model-agnostic test design

Core Tests

Overview

The core test suite consists of 7 carefully selected tests that provide ~85% coverage of critical functionality in just 5-8 minutes.

Configuration

Contains:

  • Test paths and metadata
  • Rationale for test selection
  • Coverage breakdown
  • Usage examples

The 7 Core Tests

1. Approval Gate (30-60s) ⚡ CRITICAL

File: 01-critical-rules/approval-gate/05-approval-before-execution-positive.yaml

Tests: Approval before execution workflow - the most critical safety rule

Validates:

  • ✅ Agent asks for approval before writing files
  • ✅ User approves the plan
  • ✅ Agent executes only after approval
  • ✅ Timing: approval timestamp < execution timestamp

2. Context Loading - Simple (60-90s) ⚡ CRITICAL

File: 01-critical-rules/context-loading/01-code-task.yaml

Tests: Context loading for code tasks - most common use case

Validates:

  • ✅ Agent loads .opencode/context/core/standards/code.md before writing code
  • ✅ Context loaded BEFORE execution (timing validation)
  • ✅ Proper tool usage (read → write)

3. Context Loading - Multi-Turn (120-180s) 🔥 HIGH PRIORITY

File: 01-critical-rules/context-loading/09-multi-standards-to-docs.yaml

Tests: Multi-turn conversation with multiple context files

Validates:

  • ✅ Turn 1: Loads standards context
  • ✅ Turn 2: Loads documentation context
  • ✅ Turn 3: References both contexts
  • ✅ Multi-turn approval workflow
  • ✅ Context accumulation across turns

4. Stop on Failure (60-90s) ⚡ CRITICAL

File: 01-critical-rules/stop-on-failure/02-stop-and-report-positive.yaml

Tests: Error handling - stop and report, don't auto-fix

Validates:

  • ✅ Agent runs tests
  • ✅ Tests fail
  • ✅ Agent STOPS (doesn't continue)
  • ✅ Agent REPORTS error
  • ✅ Agent PROPOSES fix
  • ✅ Agent WAITS for approval

5. Simple Task - No Delegation (30-60s) 🔥 HIGH PRIORITY

File: 08-delegation/simple-task-direct.yaml

Tests: Agent handles simple tasks directly without unnecessary delegation

Validates:

  • ✅ Simple tasks executed directly (no task tool)
  • ✅ No unnecessary subagent delegation
  • ✅ Efficient execution path

6. Subagent Delegation (90-120s) 🔥 HIGH PRIORITY

File: 06-integration/medium/04-subagent-verification.yaml

Tests: Subagent delegation for appropriate tasks

Validates:

  • ✅ Agent delegates to appropriate subagent (coder-agent)
  • ✅ Subagent executes successfully
  • ✅ Subagent uses correct tools (write)
  • ✅ Output file created with expected content
  • ✅ Delegation workflow completes

7. Tool Usage (30-60s) 📋 MEDIUM PRIORITY

File: 09-tool-usage/dedicated-tools-usage.yaml

Tests: Proper tool usage patterns

Validates:

  • ✅ Uses read tool instead of cat
  • ✅ Uses grep tool instead of bash grep
  • ✅ Uses list tool instead of ls
  • ✅ Avoids bash antipatterns

#!/bin/bash
# .git/hooks/pre-commit
npm run test:core || exit 1

This gives you:

  • ⚡ Fast CI/CD (smoke test)
  • ✅ Comprehensive local testing (core tests)
  • 🔬 Full validation on release (full suite)

Troubleshooting

Tests Timing Out

Symptoms: Test execution times out with "no activity" message

Causes:

  • OpenCode CLI not installed
  • API key not configured
  • Network issues
  • Agent not responding

Solutions:

# Check OpenCode CLI
which opencode
opencode --version

# Install if missing
npm install -g opencode-ai

# Check API key
echo $OPENCODE_API_KEY

# Run with debug
npm run test:core -- --debug

Tests Failing

Symptoms: Tests fail with violations or errors

Causes:

  • Test configuration issues
  • Agent behavior changed
  • Prompt updates needed

Solutions:

# Run smoke test first
npm run test:ci:openagent

# Run with debug
npm run test:core -- --debug

# Check specific test
npm run eval:sdk -- --agent=openagent --pattern='smoke-test.yaml' --debug

Rate Limiting

Symptoms: "Too many requests" or connection errors

Causes:

  • Too many tests too quickly
  • Free tier limits

Solutions:

  • ✅ Tests already run sequentially with 3s delays
  • ✅ Use smoke test for CI/CD (fastest)
  • ✅ Use core tests for development (reasonable)
  • Consider paid tier for full suite

Event Stream Errors

Symptoms: "Already listening to event stream"

Causes:

  • Event handler not cleaned up between tests

Solutions:

  • ✅ Already fixed in test runner
  • Event handler stops between tests
  • 500ms cleanup delay added

Session Not Found

Symptoms: "Session not found" or "No messages"

Causes:

  • Session deleted too quickly
  • Wrong project path
  • Debug mode not enabled

Solutions:

# Run with debug mode (keeps sessions)
npm run test:core -- --debug

# Check session directory
ls ~/.local/share/opencode/storage/session/

# Check project path in config

Contributing

Adding New Tests

  1. Create YAML file in appropriate category directory
  2. Follow test schema (see Test Schema section)
  3. Run test to verify it works
  4. Update documentation if adding new category

Example:

# Create test file
vim evals/agents/openagent/tests/01-critical-rules/my-test.yaml

# Run test
npm run eval:sdk -- --agent=openagent --pattern='my-test.yaml'

# If passing, commit
git add evals/agents/openagent/tests/01-critical-rules/my-test.yaml
git commit -m "feat: add my-test for critical rules"

Adding New Evaluators

  1. Create evaluator class in framework/src/evaluators/
  2. Extend BaseEvaluator
  3. Implement evaluate() method
  4. Register in test runner
  5. Add tests for evaluator

Example:

// framework/src/evaluators/my-evaluator.ts
export class MyEvaluator extends BaseEvaluator {
  name = 'my-rule';
  
  evaluate(timeline: TimelineEvent[]): EvaluationResult {
    // Your evaluation logic
    return {
      passed: true,
      violations: []
    };
  }
}

Modifying Core Tests

File: evals/agents/openagent/config/core-tests.json

To add/remove tests from core suite:

  1. Edit core-tests.json
  2. Update test paths
  3. Update documentation

  4. Test the core suite

    {
"tests": [
{
  "id": 8,
  "name": "My New Test",
  "path": "path/to/test.yaml",
  "category": "critical-rules",
  "priority": "critical",
  "estimatedTime": "30-60s",
  "description": "What it tests"
}
]
}
