Online event

Agenda
See what’s in the program!
Join us for the third Talk4Devs meetup with Rafał Sokulski, dedicated — unsurprisingly — to blockchain! This time, we’ll tackle a topic that intrigued many participants of the previous editions: how do you test Smart Contracts? Is “clicking around manually” the only option, or is it actually possible to write unit tests?
During the event, you’ll learn:
How to manually verify whether a Smart Contract works correctly.
How to use Mocha and Chai to create unit tests.
How to measure code coverage for your tests.
Together, we’ll clear up the doubts surrounding testing code running on the Ethereum Virtual Machine.
