Скачать или смотреть UI and Unit Testing with Airbnb's Enzyme - Ryan Walsh

An introduction to testing React components using Enzyme and Jest. UI Testing no longer needs to be the painful mess it used to be. Using AirBnB's Enzyme and Facebook's Jest we can breeze through component structure and cut tests down to concise, intuitive blocks.

Below are some transcriptions of the questions at the end:
Q1[32:00]: Will these tools work for testing with Redux?
Q2[32:38]: In one of your early examples you used Enzyme to test a component's text. Would you use Enzyme or Snapshots for that?
Q3[33:05]: How do Jest mocks compare to Sinon?
Q4[33:21]: What font are you using? (https://github.com/tonsky/FiraCode)
Q5[33:18]: How performant is Jest?
Q6[34:56]: Can I use these tools to test other things?
Q7[36:11]: Why do you unit test your UI, shouldn't this be handled with end-to-end tests, integration tests, or QA? Isn't the cost of testing these sign
Q8[37:00]: Do you have a twitter? (yes! @_rtwalsh)
Q9[37:40]: Why did you check against the internal state instead of checking the rendered version in one of your examples?
Q10[38:37]: I have problems with Enzyme requiring lot's of test changes to stay up to date with testing an existing UI. Do you have problems with these tools being fragile?
Q11[39:34]: Other test frameworks allow you to provide helper text with each of your assertions, doesn't that solve your concern about the unit test that was testing too much?
Q12[40:16]: How are snapshots providing a benefit? Won't the CI or other tools create their own snapshots?
