jest: Watch mode crashes with ProcessTerminatedError in new test pattern mode

git clone https://github.com/facebook/react.git
cd react
yarn
npm test -- --watch Perf

t
returns <Enter>

The watch mode crashes:

 FAIL  src/renderers/dom/shared/__tests__/ReactBrowserEventEmitter-test.js

A worker process has quit unexpectedly! Most likely this an initialization error.

If I just run npm test -- --watch ReactBrowserEventEmitter I can’t reproduce this.

Try adding jest.useFakeTimers(); above your it blocks. You don’t need to make any global config changes that way.

describe(SomeAnimatedComponent, () => {
    jest.useFakeTimers();

    it('works', () => {
        // ...tests
    });
});

Getting this issue in our app with react-native while running tests. Adding: "jest": { ... "timers": "fake" ... } resolved the issue. Stacktrace (without timers: fake ): TypeError: Cannot read property 'Object.<anonymous>' of null at Runtime._execModule (/opt/application/node_modules/jest-runtime/build/index.js:518:64) at Runtime.requireModule (/opt/application/node_modules/jest-runtime/build/index.js:332:14) at Runtime.requireModuleOrMock (/opt/application/node_modules/jest-runtime/build/index.js:408:19) at Function.bezier (/opt/application/node_modules/react-native/Libraries/Animated/src/Easing.js:228:13) at ease (/opt/application/node_modules/react-native/Libraries/Animated/src/Easing.js:94:14) at TimingAnimation._easing (/opt/application/node_modules/react-native/Libraries/Animated/src/Easing.js:260:8) at TimingAnimation.onUpdate (/opt/application/node_modules/react-native/Libraries/Animated/src/animations/TimingAnimation.js:138:6) at ontimeout (timers.js:469:11) at tryOnTimeout (timers.js:304:5) at Timer.listOnTimeout (timers.js:264:5)
