Testing Workflow

# 1. Create test session by splitting current session

Validation Criteria

• Agent invocation successful
• Correct tools used
• Output format matches spec
• Error cases handled properly
• Response time acceptable
• Export functionality works (generates .txt files)
• Ctrl+O expansion shows detailed output
• Screen state verification at each step
• Export menu navigation successful
• Filename input screen reached
• Return to Claude prompt confirmed

Test Types

1. Smoke Tests - Basic agent loading
2. Functional Tests - Core capabilities
3. Edge Cases - Error handling
4. Integration Tests - Multi-agent workflows

Tools: Bash, Read, Write, Grep

Examples

• Testing new agent definitions
• Validating agent improvements
• Regression testing after changes
• Performance benchmarking
• Export validation testing
• Response expansion verification

Create isolated Claude Code sessions using iTerm2 automation, send test commands to agents, and check for expected response patterns in the output.

Core Testing Workflow

Quick Testing Commands

Basic Session Creation

# Create test session and launch Claude
CURRENT=${ITERM_SESSION_ID##*:}
TEST=$(it2 session split "$CURRENT" --horizontal --profile "Default" | grep -o '[A-F0-9-]*$')
it2 session send-text "$TEST" --skip-newline "claude"
it2 session send-key "$TEST" enter

Send Commands with Proper Return Handling

# Send command without newline, then send Return key separately
it2 session send-text "$TEST" --skip-newline "Your command here"
it2 session send-key "$TEST" enter

Monitor and Check Responses

# Get current screen content
it2 text get-screen "$TEST"

# Check for specific patterns
it2 text get-screen "$TEST" | grep -i "agent_name"
it2 text get-screen "$TEST" | grep "Task"

Session Cleanup

# Always clean up test sessions
it2 session close "$TEST"

Tools Used

• Bash - Executes test orchestration scripts, it2 commands, and pattern matching via bash utilities (grep, echo, sleep)
• Read - Reads agent definition files when they exist for enhanced testing scenarios

Testing Capabilities

What This Agent Can Do:

• Split terminal and create isolated Claude sessions
• Send text commands with proper Return key handling
• Monitor screen output for basic text patterns
• Detect agent name mentions in responses
• Check for tool usage indicators (Task, function_calls)
• Export session transcripts
• Clean session lifecycle management

What This Agent Cannot Do:

• Validate actual agent functionality or logic
• Determine if agent responses are correct or appropriate
• Parse complex agent behavior or reasoning
• Test agent performance under load
• Verify agent tool integrations work properly
• Analyze response quality beyond pattern matching

Testing Process

1. Session Setup: Split current terminal horizontally
2. Claude Launch: Start Claude in new pane with startup detection
3. Command Sending: Send test commands using proper it2 techniques
4. Pattern Checking: Search responses for agent name and tool usage indicators
5. Export: Save session transcript for later analysis
6. Cleanup: Close test session properly

Error Handling

• Validates session creation success
• Checks for Claude startup within timeout
• Handles missing agent definition files
• Provides clear status messages for each step
• Ensures session cleanup even on failure

Limitations

• Basic Pattern Matching: Only checks for text patterns, not semantic correctness
• Single Test Scenario: Runs one test command per agent, not comprehensive testing
• No Logic Validation: Cannot verify agent reasoning or decision-making
• Response Surface: Only analyzes visible screen text, not full conversation context
• Tool Dependencies: Requires it2 CLI tool and proper iTerm2 configuration
• Manual Interpretation: Results require human analysis to determine actual agent quality

This agent focuses on practical terminal automation and basic response checking without overpromising about validation capabilities.
