My previous blog post, Python Mocking 101: Fake It Before You Make It , discussed the basic mechanics of mocking and unit testing in Python. This post covers some higher-level software engineering principles demonstrated in my experience with Python testing over the past year and half. In particular, I want to revisit the idea of patching mock.

Welcome to a guide to the basics of mocking in Python. It was born out of my need to test some code that used a lot of network services and my experience with GoMock , which showed me how powerful mocking can be when done correctly (thanks, Tyler ). I'll begin with a philosophical discussion about mocking because good mocking requires a different.

Fugue uses Python extensively throughout the Conductor and in our support tools, due to its ease-of-use, extensive package library, and powerful language tools. One thing we've learned from building complex software for the cloud is that a language is only as good as its debugging and profiling tools. Logic errors, CPU spikes, and memory leaks.

"Much more than encryption algorithms, one-way hash functions are the workhorses of modern cryptography." —Bruce Schneier

 

Cryptographic hashes (or one-way hash functions) allow us to compute a digest that uniquely identifies a resource. If we make a small change anywhere in a resource, its digest also changes—drastically, because of the .

Here at Fugue , the Web Team is a small but spirited minority—in favor of JavaScript, 60 frames per second , and keeping our DevOps simple. We like experimentation and new approaches to computing that favor substance and elegance over fad and bling. For some time, we’ve been using AWS Lambda with SNS topics and votebots , but we hadn’t tried.

This fall, I had the chance to dive headfirst into functional programming languages. It’s not a journey for the dabbler or the faint of heart, but it's one that’s worthwhile.

 

I'd been aware of functional programming and Haskell in particular for some time, but my attempts to learn it had been less than successful. The problem wasn’t lack of.

Here at Luminal , work on a major component of Fugue began in Python 2.7. For this component, we had some early deadlines and a lot of architecture to figure out and prove, so for implementation, we went with what was familiar. We think this was the right decision.

 

However, after we met our deadlines, we took some time to reconsider our.
