09-09, 17:00–19:00 (Europe/Lisbon), Workshop I
Have you introduced bugs to your project when refactoring or making a “small” change to your code? Do you want to make your code base bulletproof? Learn how and when to write property-based tests, with little effort but significant benefits.
One of the main premises when writing production-ready code is to make it as reliable as possible, therefore we can implement new features, refactor and make changes to our code with confidence. One tool that helps us achieve this goal is testing.
What is the first thing that comes to mind when talking about testing? Probably the test pyramid: unit, integrations, and E2E tests, and often that is enough when implementing tests in our codebase. But, what if you could boost all of them with little effort and make your codebase even more reliable?
It's almost impossible to capture all of the edge cases that can occur in our application and reflect those cases as tests. In this workshop, we’ll use the Hypothesis Python testing library to help us generate random data and run multiple test cases with arbitrary inputs in order to increase our trust and coverage in our test suite. So we can break… sorry, refactor our code with confidence :).
After this workshop, you’ll be able to start including property-based tests in your project, and you’ll also be able to identify the main cases where property testing makes sense (Spoiler alert! Not all tests should be implemented with a property-based approach)
I’m Felix Miño, software developer at Stack Builders, two-time PyCon Latam speaker, one-time at Pycon Colombia, and one-time speaker at DjangoCon Europe. I have more than 4 years of experience in the software industry and have had the chance to work on different projects with various programming languages such as Python, Haskell, and TypeScript. Since 2022, I lead the “Quito Lambda” Meetup community in Ecuador, a space that aims to share topics mainly related to the functional programming paradigm and its usage. I’m eager to share what I’ve learned over these years with a broader software community. During my free time, I enjoy cooking and discovering the world through its flavors. Lately, I’ve been into running and trailing.
