Thanks for coming to the talk, here are my notes.
To check out the talk run yarn && yarn start
To check out the tests go into the test-example folder and run yarn && yarn test.
Don't worry about all the red, it's from the test where we check that it throws.
To checkout the counter example go into example folder and run yarn && yarn start.
I use jest as my test framework.
The vscode plugin I used to do live testing is wallabyjs.
And the testing library I wrote for testing hooks is test-react-hooks.
Try it out, give it a star if you like it and raise an issue if you find any problems.
