Secure your Python code with fuzz testing English

In this lecture we will be talking about fuzz testing, a process for finding bugs in your code which may also be security vulnerabilities.

If you are using property-based testing with Hypothesis, this means that you are already fuzzing your code. But we aren't going to talk about Hypothesis here, or, at least not much.

We will start with what fuzzing is and where does it come from and then we will learn about Atheris, a coverage guided fuzzer for Python and CPython extensions code. We will look how and what for others use it to see how we can leverage it to test our code better.
