## Executive Summary
This comprehensive test suite verified that the MCP Console Automation server properly handles SSH connection errors without crashing or becoming unresponsive. The tests systematically triggered various SSH error conditions and monitored server behavior.
### Key Metrics

- **Total Individual Tests:** ${this.testResults.reduce((sum, r) => sum + r.testsRun, 0)}
- **Tests Passed:** ${this.testResults.reduce((sum, r) => sum + r.testsPassed, 0)}
- **Tests Failed:** ${this.testResults.reduce((sum, r) => sum + r.testsFailed, 0)}
- **Server Crashes:** ${this.testResults.reduce((sum, r) => sum + r.serverCrashes, 0)}
- **Memory Leaks:** ${this.testResults.reduce((sum, r) => sum + r.memoryLeaks, 0)}

## Test Commands to Reproduce Issues
To reproduce any SSH crash issues manually, use these exact commands:
### 1. Invalid Host Test
\`\`\`json
{
"jsonrpc": "2.0",
"method": "tools/call",
"params": {
"name": "console_create_session",
"arguments": {
"command": "echo test",
"consoleType": "ssh",
"sshOptions": {
"host": "invalid-host-that-does-not-exist.local",
"username": "testuser",
"password": "testpass"
}
}
}
}
\`\`\`
**Expected Behavior:** Server should return error response but continue running
**Expected in mcp-debug.log:** "SSH/Network error isolated", "Server MUST continue"
### 2. Wrong Credentials Test
\`\`\`json
{
"jsonrpc": "2.0",
"method": "tools/call",
"params": {
"name": "console_create_session",
"arguments": {
"command": "echo test",
"consoleType": "ssh",
"sshOptions": {
"host": "localhost",
"username": "invalid_user",
"password": "wrong_password"
}
}
}
}
\`\`\`
**Expected Behavior:** Authentication error, server continues
**Expected in mcp-debug.log:** "Authentication failed", "Check SSH credentials"
### 3. SSH Executable Not Found Test
\`\`\`json
{
"jsonrpc": "2.0",
"method": "tools/call",
"params": {
"name": "console_create_session",
"arguments": {
"command": "echo test",
"consoleType": "ssh",
"sshOptions": {
"host": "localhost",
"username": "testuser",
"sshExecutable": "/non/existent/ssh/path"
}
}
}
}
\`\`\`
**Expected Behavior:** ENOENT error handled gracefully
**Expected in mcp-debug.log:** "ENOENT", "SSH client not found", "trying alternative"
## Verification Steps
To verify the server stays alive after SSH errors:
1. **Start MCP Server:** \`node dist/mcp/server.js\`
2. **Send SSH Error Request:** Use one of the commands above
3. **Check Process:** Server process should still be running
4. **Test Responsiveness:** Send \`{"jsonrpc":"2.0","method":"tools/list"}\` - should get response
5. **Check Debug Log:** Should contain isolation messages, no crashes
## Debug Log Analysis
Monitor \`mcp-debug.log\` for these key indicators:
✅ **Good Signs:**
- "SSH/Network error isolated"
- "Server MUST continue"
- Error classification messages
- No uncaught exceptions
❌ **Bad Signs:**
- Uncaught exceptions
- Process termination messages
- Missing error isolation
- Sensitive data in logs (passwords, keys)
