Technology Compatibility Kit (TCK) for Chaos Hub client and servers implementations.
The purpose of this project is to provide a technology compatibility kit for client and server developers of Chaos Hub systems. The commercial Chaos Hub uses and maintains this TCK to ensure that it's API remains open and compatible with all other client and server implementations.
The project contains Chaos Hub server and client TCKs that aim to faciliate and accelerate the development of both Chaos Hub server and client compatible implementations.
There are two features in this project that support the development of compatible Chaos Hub servers:
- An Open API specification that describes the API that your Chaos Hub server must support.
- A set of example interactions and scenarios that you can use to test the behaviour of your Chaos Hub server
This project contains a sample Open API (Swagger) specification for the interface that should be supported by a compatible Chaos Hub server implementation. Your starting point for developing your own Chaos Hub compatible server should be this specification).
The easiest way to begin your Chaos Hub server (and client) side development is to take the Chaos Hub Open API 2 specification and use the free Swagger Codegen tool.
Also included is a growing set of example interactions and scenarios that work against your server implementation to ensure its behaviour matches what is expected beyond the simple Open API 2 specification.
You can execute these scenarios by changing the usageTests.sh file to point at your own server's URL and then executing the usageTests.sh script.
There are two features in this project that support the development of compatible clients for the Chaos Hub:
- An Open API specification that can be used to generate client-side code.
- A sample server that can be executed to test your client-side code against.
The easiest way to begin your Chaos Hub client (and server) side development is to take the Chaos Hub Open API 2 specification and use the free Swagger Codegen tool to generate client stubs for your chosen language and frameworks.
The sample Chaos Hub server is built using the connexion Python library. You will need to set up this project for development in order to use the server by executing the following command.
$ python setup.py developOnce you have set up the project the sample Chaos Hub server can be executed using the following command from the root directory of this project:
$ python servertck.pyThe sample Chaos Hub server takes advantage of connexion's support for an in-built Swagger UI that you can use to explore the Chaos Hub's Open API specification. Once the server is running you can access this UI by opening http://localhost:8080/ui in your browser.
Contributors to this project are welcome as this is an open-source effort that seeks discussions and continuous improvement.
From a code perspective, if you wish to contribute, you will need to run a Python 3.5+ environment. Then, fork this repository and submit a PR. The project cares for code readability and checks the code style to match best practices defined in PEP8. Please also make sure you provide tests whenever you submit a PR so we keep the code reliable.
If you wish to develop on this project, make sure to install the development dependencies. But first, create a virtual environment and then install those dependencies.
$ pip install -r requirements-dev.txt -r requirements.txt Then, point your environment to this directory:
$ python setup.py developTo run the tests for the project execute the following:
