Mite: the mighty performance testing framework

Mite is a performance testing framework created by the performance testing in Sky UKʼs Identity group. The philosophy driving the effort was simple:

1. Scalability. The apps that we test are scalable, distributed systems; our performance testing framework should be as well.

2. Maintainability. As software engineers, we have a full arsenal of information organization and reuse techniques. We should treat our performance tests as code, and bring these same techniques to bear.

3. Snakiness. Python is the best language for us to accomplish our goals for the project.
