- Foldable left panel (user profile) and right panel (task details) - Clicking a task in the list or graph node selects it and shows details - Both views (task list + graph) always mounted via absolute inset-0 for correct canvas dimensions; tabs toggle visibility with opacity - Graph node selection animation: other nodes repel outward (charge -600), then selected node smoothly slides to center (500ms cubic ease-out), then charge restores to -120 and graph stabilizes - Graph re-fits on tab switch and panel resize via ResizeObserver - Fix UUID string IDs throughout (backend returns UUIDs, not integers) - Add TaskDetailPanel, UserPanel components - Add CLAUDE.md project documentation Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

jest-circus
The next-gen test runner for Jest
Overview
Circus is a flux-based test runner for Jest that is fast, maintainable, 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 {Event, State} from 'jest-circus';
import {TestEnvironment as NodeEnvironment} from 'jest-environment-node';
class MyCustomEnvironment extends NodeEnvironment {
//...
async 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.
Note, that jest-circus test runner would pause until a promise returned from handleTestEvent gets fulfilled. However, there are a few events that do not conform to this rule, namely: start_describe_definition, finish_describe_definition, add_hook, add_test or error (for the up-to-date list you can look at SyncEvent type in the types definitions). That is caused by backward compatibility reasons and process.on('unhandledRejection', callback) signature, but that usually should not be a problem for most of the use cases.
Installation
Note: As of Jest 27,
jest-circusis the default test runner, so you do not have to install it to use it.
Install jest-circus using yarn:
yarn add --dev jest-circus
Or via npm:
npm install --save-dev jest-circus
Configure
Configure Jest to use jest-circus via the testRunner option:
{
"testRunner": "jest-circus/runner"
}
Or via CLI:
jest --testRunner='jest-circus/runner'
