Special Guests: Ben Coe, Aaron Abramov, and Issac Schleuter

In this episode, the JavaScript Jabber panelists talk with Ben Coe, Aaron Abramov, and Issac Schleuter about test coverage and testing tools. They talk about the different tools and libraries that they have contributed to the coding community, such as NYC, conf, and Jest. They also discuss what test coverage is actually about and when using test coverage tools is necessary.

In particular, we dive pretty deep on:

What have you contributed to the testing tools community?
npm
NYC tool and instanbul project
conf
Jest
These libraries were developed to be easy and have “batteries included”
False positives with test coverage
Encourage testing practices that don’t practice in a superficial way
Test coverage is about making sure you test every state a public API can get into
Think through the test you’re writing first
Barriers against testing
Don’t spike the code too quickly
Provides guardrails for newer developers to contribute to open source projects
Use tests to understand the system
How to spend your time better
When you need tests
Value is very short term
TDD
And much, much more!
