Test doubles? Assertions? Code coverage? Jest has it all! There are many testing frameworks and test utilities in the JavaScript ecosystem, but jest is the one which is quickly becoming a favorite for many developers. The talk will introduce jest as a testing framework, the reasons why developers love it, and explore its hidden features, testing patterns, and Jest's extensions ecosystem.

Good argument coverage, but it seemed like the speaker tried to squeeze a 40 minutes talk into 25. Too fast!

Very good subject. Very good speaker. Very good presentation.
The only bad thing? The time...too little, and so, too fast explanation...
Many thanks to Liran!

Good talk but speaker behaved like he was in a hurry.
It’s a pity ad topic is hot and really interesting

Very interesting and great speaker!

Loved the talk, great resources, and examples. It felt a little rushed but didn't actually feel that fast at all.

Great talk with a large overview of jest :)
I do not put a five because I thought I would learn more testing patterns, and not exclusively about jest

Node.js and JavaScript adoption is high and application security plays a big part in shipping your products in the midst of cyber security threats. We will deep-dive into practical Node.js security measures which you can easily implement in your current projects. Covering topics such as OWASP Top 10 vulnerabilities, Secure Code Guidelines, Leveraging recommended npm libraries, Hardening ExpressJS, and Secure Dependencies Management with CI/CD integration.

Thanks for attending and all the feedback!
Slides are available at http://slides.com/lirantal/jest-testing-patterns and I'd be happy to further discuss Jest and any questions around testing patterns on twitter, my DM are open

Good presentation, at times a bit fast but always nice to follow.
