🛠️ Developer Tools

Rails Generators

# Generate complete workflow
rails generate tasker:workflow ecommerce process_order

# Generate step handler
rails generate tasker:step_handler ecommerce process_order validate_payment

Testing Infrastructure

# Built-in test helpers
include Tasker::SpecHelpers

result = run_task_workflow(
  'process_order',
  namespace: 'ecommerce',
  context: { order_id: 123 }
)

expect(result.status).to eq('completed')

Debug Tools

# Task inspection
task = Tasker::Task.find(task_id)
puts task.inspect_execution

# Performance analysis
Tasker::Analytics.workflow_performance('ecommerce', 'process_order')
