Module: OrigenTesters::Flow

Includes:
ATP::FlowAPI, Generator
Included in:
IGXLBasedTester::Base::Flow, SmartestBasedTester::Base::Flow
Defined in:
lib/origen_testers/flow.rb

Overview

Provides a common API to add tests to a flow that is supported by all testers.

This builds up a flow model using the Abstract Test Program (ATP) gem, which now deals with implementing the flow control API.

Individual tester drivers in this plugin are then responsible at the end to render the abstract flow to their specific format and conventions.
