JEST JEST

Jacek Rzeszutek (@grechut)

What is Jest?

How do I use it for my first test?

How does it integrate with Babel?

Why snapshots might be interesting?

How do I CREATE mockS?

(ACTUALLY STUBS)

How do I check if my team keeps on writing tests?

WHAT MAKES IT FAST?

Any questions?

Thanks!

DZIĘKUJU!
