Fai Polyglot Test

Generates tests across Python, TypeScript, C#, Java — detects language and applies appropriate framework.

Overview

This skill provides a structured, repeatable procedure for generates tests across python, typescript, c#, java — detects language and applies appropriate framework.. It can be used standalone as a LEGO block or auto-wired inside solution plays via the FAI Protocol.

Category: Testing Complexity: Medium Estimated Time: 10-30 minutes

Parameters

Parameter	Type	Required	Default	Description
target	string	Yes	—	Target resource, file, or endpoint
environment	enum	No	dev	Target environment: dev, staging, prod
verbose	boolean	No	false	Enable detailed output logging
dry_run	boolean	No	false	Validate without making changes
config_path	string	No	config/	Path to configuration directory

Steps

Step 1: Validate Prerequisites

Verify all required tools, credentials, and dependencies are available.

# Check required tools
command -v node >/dev/null 2>&1 || { echo 'Node.js required'; exit 1; }
command -v az >/dev/null 2>&1 || { echo 'Azure CLI required'; exit 1; }

Step 2: Load Configuration

Read settings from the FAI manifest and TuneKit config files.

# Load from fai-manifest.json if inside a play
CONFIG_DIR="${config_path:-config}"
if [ -f "fai-manifest.json" ]; then
  echo "FAI Protocol detected — auto-wiring context"
fi

Step 3: Execute Core Logic

Perform the primary operation: generates tests across python, typescript, c#, java — detects language and applies appropriate framework..

Step 4: Validate Results

Verify the output meets quality thresholds and WAF compliance.

# Validate output
if [ "$?" -eq 0 ]; then
  echo "✅ Skill completed successfully"
else
  echo "❌ Skill failed — check logs"
  exit 1
fi

Output

Output	Type	Description
status	enum	success, warning, failure
duration_ms	number	Execution time in milliseconds
artifacts	string[]	List of generated/modified files
logs	string	Detailed execution log

WAF Alignment

Pillar	How This Skill Contributes
reliability	Includes retry logic, validates outputs, provides rollback steps
operational-excellence	Produces structured logs, integrates with CI/CD, follows IaC patterns

Compatible Solution Plays

• Play 32

Error Handling

Exit Code	Meaning	Action
0	Success	Proceed to next step
1	Validation failure	Check input parameters
2	Dependency missing	Install required tools
3	Runtime error	Check logs, retry with --verbose

Usage

Standalone

# Run this skill directly
npx frootai skill run fai-polyglot-test

Inside a Solution Play

When referenced in fai-manifest.json, this skill auto-wires with the play's context:

{
  "primitives": {
    "skills": ["skills/fai-polyglot-test/"]
  }
}

Via Agent Invocation

Agents can invoke this skill using the /skill command in Copilot Chat.

Configuration Reference

{
  "skill": "skill-name",
  "version": "1.0.0",
  "timeout_seconds": 300,
  "retry_attempts": 3,
  "log_level": "info"
}

Monitoring

Track skill execution metrics:

Metric	Description	Alert Threshold
Duration	Execution time	> 60 seconds
Success rate	Pass/fail ratio	< 95%
Error count	Failed executions	> 5/hour

Troubleshooting

Symptom	Cause	Fix
Timeout	Slow dependency	Increase timeout_seconds
Auth failure	Expired credentials	Refresh Managed Identity
Missing config	No fai-manifest.json	Create manifest or pass config_path
Validation error	Invalid input	Check parameter types and ranges

Notes

• This skill follows the FAI SKILL.md specification
• All outputs are deterministic when dry_run=true
• Integrates with FAI Engine for automated pipeline execution
• Part of the Testing category in the FAI primitives catalog
