Introduction

The Adapt module provides utilities to simplify development and testing of other modules.

Basic concepts

Simulated mode

To allow testing a Lua module together with an operational systems while causing zero or minimal impact on the latter, one or more of the software interfaces may be placed in simulated mode, thereby interacting with alternative data sources or sinks. The alternative functions are provided by the calling module.

For each interface, normal operation is indicated by mode 0 (the default), while a non-zero mode indicates which alternative function is used for simulation. There can be any number of alternative functions available, but only one function may be selected per interface at the same time.
