jest-doctor is a custom Jest environment that detects async leaks within tests and fails flaky tests deterministically.
Usage
Out-of-the-box jest-doctor supports node and jsdom environments.
Add one of the environments to your Jest config:
``js``
export default {
testEnvironment: "jest-doctor/env/node",
// optional
reporters: ["default", "jest-doctor/reporter"],
};
Run your tests as usual and jest-doctor will report leaks such as unresolved promises or timers.
