This talk shows how quick and simple it can be to write end-to-end tests for web applications – if your testing tools are not fighting you all the time. I will go over writing E2E tests using Cypress.io, controlling the network during tests, using visual testing and setting up continuous integration to perform E2E tests on each commit.

Cypress.io – the State of the Art End-to-end Testing Tool

Tools that supercharge unit, integration, and end-to-end tests, with a focus on Cypress.

Day to day I work on Cypress.io, an open source end-to-end test runner. And I love it - but there are other tools that help me write better tests and better code. 

In this presentation, I will show some of my favorite tools that complement, extend and supercharge my unit, integration and end-to-end tests.

Testing Tools and Their Friends

Cypress.io is an open source free end-to-end test runner that runs your web application inside an iframe in a browser it can closely control. This architecture completely changes how your tests behave (hint: no flake), what you can test (pretty much everything), and why you write more e2e tests (because you love writing them). In this talk, I will give a very brief intro into Cypress itself but mostly will concentrate on how it changes the entire testing experience. Cypress users can test web applications by observing just the external behavior (DOM, network calls, storage) or can reach deep inside the application's code, and I will explain the trade-offs. Finally, I will discuss why Cypress tests do not use "async / await" keywords, and instead look like declarative reactive streams.
