flow

Testing framework

• api Core type declarations
• message Implementations of the Message interface
• builder Implementations of the Flow and Interaction interfaces
• model Implementations of the Model interface
• validation Checking model consistency
• assert Comparing models against systems
• report Visualising assertion results
• aggregator Aggregates build artifacts
• example Service constellation to exercise the flow framework
• doc Documentation resources

Overview

This project provides a framework in which the flow of data in a system can be modelled. This model can then be used to drive testing, both of the complete system and of subsystems in isolation. These tests produce a rich execution report, for example.

This document describes the motivations for this approach.

Usage

• Quickstart guide: Illustrates the construction of a simple system model and its usage.
• Further reading: Covers more advanced usage.
• The submodules under example illustrate a complete service constellation with flow-based testing
