jest-circus
The next-gen test runner for Jest
Overview
Circus is a flux-based test runner for Jest that is fast, easy to maintain, and simple to extend.
Circus allows you to bind to events via an optional event handler on any custom environment. See the type definitions for more information on the events and state data currently available.
import {NodeEnvironment} from 'jest-environment-node';
import {Event, State} from 'jest-circus';
class MyCustomEnvironment extends NodeEnvironment {
//...
handleTestEvent(event: Event, state: State) {
if (event.name === 'test_start') {
// ...
}
}
}
Mutating event or state data is currently unsupported and may cause unexpected behavior or break in a future release without warning. New events, event data, and/or state data will not be considered a breaking change and may be added in any minor release.

yarn add --dev jest-circus
