Testing with component harnesses for the win

“If you’re torn between end-to-end testing and unit testing to validate the behavior of your UI components, component harnesses are a great solution to write meaningful, readable tests that scale and remain maintainable.

By using the harness API, a test insulates itself against updates to the internals of a component, such as changing its DOM structure.

Alain will showcase a few real life examples of how test harnesses can boost your testing productivity while allowing you to write beautiful, reusable test code.”
