Great video! It would be great if you could create video for testing stores and redux

Great lesson and nice demo ... everything is working fine just the "open:coverage", says 'open' is not recognized as an internal or external command

i tried all the transformer.js babelrc, webpack.config.js and even jest.config.js still css is not ignored in testing

Can't get what's the point of directly calling React lifecycle methods in test through the wrapper instance. Aren't you testing the implementation instead of what the user actually see and interact with? What if tomorrow you decide (for example) to refactor your component from class to function/hooks? In that case, you're gonna need to rewrite your test from scratch, arent' you?
