Detox integration with jest - Jest did not exit one second after the test run has completed.

[scriptMQL]

Description

hey guys i will run in my project unit test by jest and end to end test by detox. All my jest test work fine , but when i start detox withthe command "detox test -c ios.sim.debug --loglevel verbose" it go until the cleanup function and stop. Then call the "Jest did not exit one second after the test run has completed."

I have test forceExit but it doesn't work. issues387

Steps to Reproduce

to reproduce this issue use this config for jest in the package.json

"jest": { "preset": "react-native", "verbose": true, "testPathIgnorePatterns": [ "node_modules" ], "unmockedModulePathPatterns": [ "node_modules/react/", "node_modules/enzyme/" ], "setupFiles": [ "./config/enzyme.js" ], "snapshotSerializers": [ "enzyme-to-json/serializer" ], "transform": { "^.+\\.js$": "<rootDir>/node_modules/react-native/jest/preprocessor.js", "^.+\\.jsx?$": "babel-jest" }, "transformIgnorePatterns": [ "node_modules/(?!react-native|react-navigation)/" ], "testMatch": [ "<rootDir>/**/**/**/__tests__/*.test.js?(x)", "<rootDir>/**/**/**/__tests__/*.test.js" ] },"detox": { "test-runner": "jest", "setupTestFrameworkScriptFile": "./e2e/init.js", "runner-config": "e2e/config.json", "configurations": { "ios.sim.debug": { "binaryPath": "ios/build/Build/Products/Debug-iphonesimulator/dummy.app", "build": "xcodebuild -project ios/dummy.xcodeproj -scheme dummy -configuration Debug -sdk iphonesimulator -derivedDataPath ios/build", "type": "ios.simulator", "name": "iPhone X" } }

following my setup file:

`// config/enzyme.js
import { configure } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';

configure({ adapter: new Adapter() });

`

Additional my config.js and init.js for detox

{ "setupTestFrameworkScriptFile": "./init.js" }

init.js

`
const detox = require('detox');
const config = require('../package.json').detox;
const adapter = require('detox/runners/jest/adapter');
const { execSync } = require('child_process');

execSync('react-native run-ios');
// Set the default timeout
jest.setTimeout(40000);
jasmine.getEnv().addReporter(adapter);
// jasmine.DEFAULT_TIMEOUT_INTERVAL = 10000;

beforeAll(async () => {
await detox.init(config);
console.log('********************* INIT.js -> beforeAll');
});

beforeEach(async () => {
await adapter.beforeEach();
console.log('********************* INIT.js -> beforeEach');
});

afterAll(async () => {
console.log('********************* INIT.js -> befor adapter.afterAll');
await adapter.afterAll();
console.log('********************* INIT.js -> after adapter.afterAll / before cleanup');
await detox.cleanup();
console.log('********************* INIT.js -> after cleanup');
console.log('EXIT');
});
`

At last i my e2e test.js

`
/* eslint-disable */
import { recordVideo, killSimctl } from '../init';

describe('panel test', () => {
beforeEach(async () => {
await device.reloadReactNative();
console.log('********************* test.js -> reloadReactNative');
recordVideo();
console.log('********************* test.js -> recordVideo');
});

afterEach(async () => {
    await device.terminateApp();
    console.log('********************* test.js -> terminateApp');
    killSimctl();
    console.log('********************* test.js -> killSimctl');
});


it(' test tabbar onPress !', async () => {
    await element(by.id('GitHub')).tap();
    await expect(element(by.label('GitHub'))).toBeVisible();
    setTimeout(1000);
    await element(by.label('Components')).tap();
    await expect(element(by.label('Components'))).toBeVisible();
    setTimeout(1000);
    await element(by.label('Home')).tap();
    await expect(element(by.label('Home'))).toBeVisible();
    setTimeout(1000);
    await element(by.label('Views')).tap();
    await expect(element(by.label('Views'))).toBeVisible();
    console.log('********************* test.js -> test passed');
});

});

Jest did not exit one second after the test run has completed.

This usually means that there are asynchronous operations that weren't stopped in your tests. Consider running Jest with --detectOpenHandles to troubleshoot this issue.

[stevechun]

As a workaround, try detox test -c ios.sim.debug --forceExit
If this doesn't work, the you can try manually setting --forceExit on detox/local-cli/detox-test.js line 135, directly to jest command.

[rotemmiz]

There's too much configuration here to try reproducing it outside your project.
If you believe this is a bug in Detox please create a small demo project that recreates this bug, and share with with us.

[scriptMQL]

@stevechun if I run detox test -c ios.sim.debug --forceExit became this error =>

error: unknown option `--forceExit'.

if I add "force":true in config.json then it throw this message =>

Force exiting Jest
Have you considered using --detectOpenHandles to detect async operations that kept running
after all tests finished?

@rotemmiz i have create simple git repo (https://github.com/scriptMQL/testProject) with the same issue

[scriptMQL]

its not an issue about detox. it was an issue in my code.

[heleneyuan]

Met the same issue. How did you resolve this? @scriptMQL

[scriptMQL]

i had an issue in my code
before:
`

import { recordVideo, killSimctl } from '../helper';

describe('panel test', () => {
beforeEach(async () => {
await device.reloadReactNative();
recordVideo();
});

afterEach(async () => {
await device.terminateApp();
killSimctl();
});

it(' test tabbar onPress !', async () => {
await element(by.id('GitHub')).tap();
await expect(element(by.label('GitHub'))).toBeVisible();
setTimeout(1000);
await element(by.label('Components')).tap();
await expect(element(by.label('Components'))).toBeVisible();
setTimeout(1000);
await element(by.label('Home')).tap();
await expect(element(by.label('Home'))).toBeVisible();
setTimeout(1000);
await element(by.label('Views')).tap();
await expect(element(by.label('Views'))).toBeVisible();
});`

after:

describe('panel test', () => {
beforeEach(async () => {
await device.reloadReactNative();
});

afterEach(async () => {

});

it(' test tabbar onPress !', async () => {
await element(by.id('GitHub')).tap();
await expect(element(by.label('GitHub'))).toBeVisible();
});

i have remove my helper functions and the test are running. So I will refactor my code.
