Caravan

The purpose of caravan is to interconnect web resources in "if this than that" manner. Also the project was built with extensibility and simplicity in mind, so you're welcome to contribute.

Documentation

There are some diagrams, describing workflow and code structure of the project. You can find them in docs/caravan.xml and open them with draw.io

Summary

• Testing
• How it works

Testing

Almost all of the present tests are environment-dependent. It means, that they require working webapps and db to success.

So, environment-independent tests could be run separately.

Run all tests: $ ./bin/nosetests

Run only environment-independent tests: $ ./bin/nosetests -a '!internal'

How it works

Abstract

The main reason of caravan's existance is to interconnect web-resources in "if this than that" manner.

Conceptions

To do its work, caravan uses a set of atomic actions called observers, organized into a network called runner. This network is in charge of data processing. Such approach allows to reuse code and adapt to wide range of interconnected resources with minimal changes to the present code.

Observers are classes that implement Observer pattern. Thank to it, it's becomes possible to organize atomic actions, incapsulated in observers, into the runner. Runner, in turn, is able to setup itself by interconnecting observers into desirable network, and therefore control it.
