Concurrency Testing For A Web Service Using Python
<p>I have a web service that is required to handle significant concurrent utilization and volume and I need to test it. Since the service is fairly specialized, it does not lend itself well to a typical testing framework. The test would need to simulate multiple clients concurrently posting to a URL, parsing the resulting Http response, checking that a database has been appropriately updated and making sure certain emails have been correctly sent/received. </p>

<p>The current opinion at my company is that I should write this framework using Python. I have never used Python with multiple threads before and as I was doing my research I came across the Global Interpreter Lock which seems to be the basis of most of Python's concurrency handling. It seems to me that the GIL would prevent Python from being able to achieve true concurrency even on a multi-processor machine. Is this true? Does this scenario change if I use a compiler to compile Python to native code? Am I just barking up the wrong tree entirely and is Python the wrong tool for this job?</p>
