Introduction

Karma has two parts, server and client (or clients). Server is the main part, it:

• watches your files
• communicates with clients and manages them (through SOCKET connection)
• serves the code and tests to clients (through HTTP)
• reposts test results to you  Client runs tests against the code and reports the results to server.
