-# Plan for showing logs for failed tests
+# Improvement Plan for tstest and tapbundle
 
 !! FIRST: Reread /home/philkunz/.claude/CLAUDE.md to ensure following all guidelines !!
 
-## Goal
+## 1. Enhanced Communication Between tapbundle and tstest
-When a test fails, we want to display all the console logs from that failed test in the terminal, even without the --verbose flag. This makes debugging failed tests much easier.
 
-## Current Behavior
+### 1.1 Real-time Test Progress API
-- Default mode: Only shows test results, no console logs
+- Create a bidirectional communication channel between tapbundle and tstest
-- Verbose mode: Shows all console logs from all tests
+- Emit events for test lifecycle stages (start, progress, completion)
-- When a test fails: Only shows the error message
+- Allow tstest to subscribe to tapbundle events for better progress reporting
+- Implement a standardized message format for test metadata
 
-## Desired Behavior
+### 1.2 Rich Error Reporting
-- Default mode: Shows test results, and IF a test fails, shows all console logs from that failed test
+- Pass structured error objects from tapbundle to tstest
-- Verbose mode: Shows all console logs from all tests (unchanged)
+- Include stack traces, code snippets, and contextual information
-- When a test fails: Shows all console logs from that test plus the error
+- Support for error categorization (assertion failures, timeouts, uncaught exceptions)
+- Visual diff output for failed assertions
 
-## Implementation Plan
+## 2. Enhanced toolsArg Functionality
 
-### 1. Update TapParser
+### 2.1 Test Flow Control ✅
-- Store console logs for each test temporarily
+```typescript
-- When a test fails, mark that its logs should be shown
+tap.test('conditional test', async (toolsArg) => {
+  const result = await someOperation();
   
-### 2. Update TsTestLogger
+  // Skip the rest of the test
-- Add a new method to handle failed test logs
+  if (!result) {
-- Modify testConsoleOutput to buffer logs when not in verbose mode
+    return toolsArg.skip('Precondition not met');
-- When a test fails, flush the buffered logs for that test
+  }
   
-### 3. Update test result handling
+  // Conditional skipping
-- When a test fails, trigger display of all buffered logs for that test
+  await toolsArg.skipIf(condition, 'Reason for skipping');
-- Clear logs after each test completes successfully
   
-## Code Changes Needed
+  // Mark test as todo
-1. Add log buffering to TapParser
+  await toolsArg.todo('Not implemented yet');
-2. Update TsTestLogger to handle failed test logs
+});
-3. Modify test result processing to show logs on failure
+```
 
-## Files to Modify
+### 2.2 Test Metadata and Configuration ✅
-- `ts/tstest.classes.tap.parser.ts` - Add log buffering
+```typescript
-- `ts/tstest.logging.ts` - Add failed test log handling
+// Fluent syntax ✅
-- `ts/tstest.classes.tap.testresult.ts` - May need to store logs
+tap.tags('slow', 'integration')
+  .priority('high')
+  .timeout(5000)
+  .retry(3)
+  .test('configurable test', async (toolsArg) => {
+    // Test implementation
+  });
+```
+
+### 2.3 Test Data and Context Sharing ✅
+```typescript
+tap.test('data-driven test', async (toolsArg) => {
+  // Access shared context ✅
+  const sharedData = toolsArg.context.get('sharedData');
+  
+  // Set data for other tests ✅
+  toolsArg.context.set('resultData', computedValue);
+  
+  // Parameterized test data (not yet implemented)
+  const testData = toolsArg.data<TestInput>();
+  expect(processData(testData)).toEqual(expected);
+});
+```
+
+## 3. Nested Tests and Test Suites
+
+### 3.1 Test Grouping with describe() ✅
+```typescript
+tap.describe('User Authentication', () => {
+  tap.beforeEach(async (toolsArg) => {
+    // Setup for each test in this suite
+    await toolsArg.context.set('db', await createTestDatabase());
+  });
+  
+  tap.afterEach(async (toolsArg) => {
+    // Cleanup after each test
+    await toolsArg.context.get('db').cleanup();
+  });
+  
+  tap.test('should login with valid credentials', async (toolsArg) => {
+    // Test implementation
+  });
+  
+  tap.describe('Password Reset', () => {
+    tap.test('should send reset email', async (toolsArg) => {
+      // Nested test
+    });
+  });
+});
+```
+
+### 3.2 Hierarchical Test Organization
+- Support for multiple levels of nesting
+- Inherited context and configuration from parent suites
+- Aggregated reporting for test suites
+- Suite-level lifecycle hooks
+
+## 4. Advanced Test Features
+
+### 4.1 Snapshot Testing
+```typescript
+tap.test('component render', async (toolsArg) => {
+  const output = renderComponent(props);
+  
+  // Compare with stored snapshot
+  await toolsArg.matchSnapshot(output, 'component-output');
+});
+```
+
+### 4.2 Performance Benchmarking
+```typescript
+tap.test('performance test', async (toolsArg) => {
+  const benchmark = toolsArg.benchmark();
+  
+  // Run operation
+  await expensiveOperation();
+  
+  // Assert performance constraints
+  benchmark.expect({
+    maxDuration: 1000,
+    maxMemory: '100MB'
+  });
+});
+```
+
+### 4.3 Test Fixtures and Factories ✅
+```typescript
+tap.test('with fixtures', async (toolsArg) => {
+  // Create test fixtures
+  const user = await toolsArg.fixture('user', { name: 'Test User' });
+  const post = await toolsArg.fixture('post', { author: user });
+  
+  // Use factory functions
+  const users = await toolsArg.factory('user').createMany(5);
+});
+```
+
+## 5. Test Execution Improvements
+
+### 5.1 Parallel Test Execution ✅
+- Run independent tests concurrently ✅
+- Configurable concurrency limits (via file naming convention)
+- Resource pooling for shared resources
+- Proper isolation between parallel tests ✅
+
+Implementation:
+- Tests with `para__<groupNumber>` in filename run in parallel
+- Different groups run sequentially
+- Tests without `para__` run serially
+
+### 5.2 Watch Mode
+- Automatically re-run tests on file changes
+- Intelligent test selection based on changed files
+- Fast feedback loop for development
+- Integration with IDE/editor plugins
+
+### 5.3 Advanced Test Filtering ✅ (partially)
+```typescript
+// Run tests by tags ✅
+tstest --tags "unit,fast"
+
+// Exclude tests by pattern (not yet implemented)
+tstest --exclude "**/slow/**"
+
+// Run only failed tests from last run (not yet implemented)
+tstest --failed
+
+// Run tests modified in git (not yet implemented)
+tstest --changed
+```
+
+## 6. Reporting and Analytics
+
+### 6.1 Custom Reporters
+- Plugin architecture for custom reporters
+- Built-in reporters: JSON, JUnit, HTML, Markdown
+- Real-time streaming reporters
+- Aggregated test metrics and trends
+
+### 6.2 Coverage Integration
+- Built-in code coverage collection
+- Coverage thresholds and enforcement
+- Coverage trending over time
+- Integration with CI/CD pipelines
+
+### 6.3 Test Analytics Dashboard
+- Web-based dashboard for test results
+- Historical test performance data
+- Flaky test detection
+- Test impact analysis
+
+## 7. Developer Experience
+
+### 7.1 Better Error Messages
+- Clear, actionable error messages
+- Suggestions for common issues
+- Links to documentation
+- Code examples in error output
+
+### 7.2 Interactive Mode (Needs Detailed Specification)
+- REPL for exploring test failures
+  - Need to define: How to enter interactive mode? When tests fail?
+  - What commands/features should be available in the REPL?
+- Debugging integration  
+  - Node.js inspector protocol integration?
+  - Breakpoint support?
+- Step-through test execution
+  - Pause between tests? 
+  - Step into/over/out functionality?
+- Interactive test data manipulation
+  - Modify test inputs on the fly?
+  - Inspect intermediate values?
+
+### 7.3 ~~VS Code Extension~~ (Scratched)
+- ~~Test explorer integration~~
+- ~~Inline test results~~
+- ~~CodeLens for running individual tests~~
+- ~~Debugging support~~
+
+## Implementation Phases
+
+### Phase 1: Core Enhancements (Priority: High) ✅
+1. Implement enhanced toolsArg methods (skip, skipIf, timeout, retry) ✅
+2. Add basic test grouping with describe() ✅
+3. Improve error reporting between tapbundle and tstest ✅
