JavaScript Exchange #7 - December 2020
William Heslam, Senior Developer
"KISS: Testing stateful React components"
Synopsis:
Testing complex stateful React components can be an error-prone chore, with implicit dependencies requiring brittle mocks and synthesised events, or alternatively, necessitating artificially partitioning your tree into stateful and stateless components.
In this talk I'll introduce a technique to explicitly expose a React component's state in a way that doesn't demand any changes to your component tree, making testing simple and highly flexible - and all it requires is a little help from a mysterious 19th-century Russian man.
Bio:
Will is a JavaScript developer with over 10 years of experience. In his spare time, he likes fiddling with Turing patterns and speculating about the Fourth Futamura Projection.
Before lockdown, he could often be found combing through second-hand book shops for obscure tomes on forgotten programming languages. Now he might have to start reading them...
