A ClojureScript library/service to test live applications.

The Elm Language encourages a particular architecture called the Elm Architecture. Go read the article.

The Elm Architecture is structured around a reactive data flow: there are three functions (event handlers, step/update, and views) that receive data (events, actions, and state).

Expressing the flow of the program in layers that communicate with data makes it easily testable. Each function can be tested in isolation.

Even more, if our data is serializable we can get hold of our user's session data and use it for testing.

If we think about Virtual DOM as the output to our view functions, then we can think about React as an effect system, that takes the output of our views and handles the DOM side-effect for us.

In a sense it would be a sorts of integration testing for our UI's.

Generative testing where the generators produce your user's data.

Having your user's sessions would let you test code changes against their previous behavior, and predict if it would break existing user experiences.

Facilier is built with boot. All the available tasks are in build.boot. The most commons are dev and auto-test.
