Werkzeug meets Raw HTTP
Werkzeug-Raw adds support to Werkzeug for accepting HTTP input from raw text, from strings or files. Compatibility with Flask makes fuzzing or testing complex HTTP requests in Flask applications very simple.
Additionally, it circumvents the need for a client/server/network setup, and goes directly from raw HTTP to WSGI environment. A large number of requests can be handled without needing to worry about secondary variables like network latency clouding the water. This is not meant as a benchmarking tool for Werkzeug or Flask.
To install Werkzeug-Raw, simply:
$ pip install werkzeug-raw
