Quick Start

1. Execute a test case

# Run a test module directory
rodski-agent run --case path/to/test_module/ --format json

# Specify browser and headed mode
rodski-agent run --case path/to/test_module/ --browser firefox --no-headless

# Set max retry count
rodski-agent run --case path/to/test_module/ --max-retry 5

2. Design a test case from requirements

# Generate test case from natural language
rodski-agent design \
  --requirement "Test login with username/password" \
  --output output/login/

# Enable visual exploration with a target URL
rodski-agent design \
  --requirement "Test login" \
  --url "https://app.example.com/login" \
  --output output/login/

3. Full Pipeline (design + validate + execute)

# Basic pipeline
rodski-agent pipeline \
  --requirement "Test user registration" \
  --url "https://app.example.com/register" \
  --output output/register/ \
  --format json

# Parallel execution with custom retry settings
rodski-agent pipeline \
  --requirement "Test checkout flow" \
  --url "https://app.example.com" \
  --output output/checkout/ \
  --parallel --max-workers 4 \
  --max-retry 5 --max-fix-attempts 3

4. Diagnose failed tests

# Diagnose from result directory
rodski-agent diagnose --result output/login/result/

# Diagnose from specific result file
rodski-agent diagnose --result output/login/execution_summary.json --format json

5. View configuration

rodski-agent config show

Output Format

All commands support --format json (default: human). JSON output follows a unified contract:

{
  "status": "success | failure | error",
  "command": "run | design | pipeline | diagnose",
  "output": { ... },
  "error": null
}

run output example

{
  "status": "success",
  "command": "run",
  "output": {
    "total": 3,
    "passed": 3,
    "failed": 0,
    "cases": [
      {"id": "c001", "status": "PASS", "time": 2.1},
      {"id": "c002", "status": "PASS", "time": 1.8}
    ]
  }
}

design output example

{
  "status": "success",
  "command": "design",
  "output": {
    "cases": ["case/c001.xml"],
    "models": ["model/model.xml"],
    "data": ["data/data.xml"],
    "summary": "Generated 3 file(s)"
  }
}

Configuration

rodski-agent looks for agent_config.yaml in this order:

1. $RODSKI_AGENT_CONFIG env var
2. ./agent_config.yaml (current directory)
3. <project_root>/config/agent_config.yaml
4. Built-in defaults

Environment variables override config file values: RODSKI_AGENT_LLM__DESIGN__MODEL=gpt-4o.

LLM Configuration

Design and Execution agents use separate LLM configurations:

llm:
  design:
    provider: claude
    model: claude-sonnet-4-20250514
    base_url: "http://code.casstime.ai"
    api_key_env: ANTHROPIC_API_KEY
    temperature: 0.7
    max_tokens: 4096
  execution:
    provider: claude
    model: claude-sonnet-4-20250514
    base_url: "http://code.casstime.ai"
    api_key_env: ANTHROPIC_API_KEY
    temperature: 0.1
    max_tokens: 2048

Architecture

Design Agent (LangGraph)

analyze_req -> explore_page -> identify_elem -> plan_cases -> design_data -> generate_xml -> validate_xml
                                                                                  ^              |
                                                                                  +-- (fail) ----+

Node	Description
analyze_req	LLM extracts test scenarios from requirements
explore_page	Playwright screenshot + OmniParser element detection
identify_elem	LLM Vision adds semantic labels to detected elements
plan_cases	Plans test case structure (phases, steps, models)
design_data	Designs test data tables
generate_xml	Generates case/model/data XML files
validate_xml	Validates with rodski validate, retries on failure

Execution Agent (LangGraph)

pre_check -> execute -> parse_result -[pass]-> report
                                     -[fail]-> diagnose -> retry_decide -[retry]-> apply_fix -> execute
                                                                        -[give_up]-> report

Node	Description
pre_check	Validate case path, directory structure, rodski version
execute	Call rodski run to execute tests
parse_result	Parse execution results
diagnose	LLM diagnoses failure root cause
retry_decide	Decide retry based on diagnosis confidence
apply_fix	Smart repair (wait/locator/data strategies)
report	Generate final report

Smart Repair Strategies

Strategy	Trigger	Fix Action
Wait	Timeout / element not ready	Insert wait step before failing step
Locator	Element not found	LLM suggests new locator, update model XML
Data	Data mismatch	LLM suggests new data value, update data XML

Pipeline Orchestrator

The pipeline command chains Design -> Validation Gate -> Execution:

1. Design Phase: Generate test case XML from requirements
2. Validation Gate: Run rodski validate on all generated XML; fail-fast if invalid
3. Execution Phase: Execute generated cases (sequential or parallel with --parallel)
