超时-在jest.setTimeout.Error指定的120000ms超时内未调用异步回调

Question

排毒测试-c android.emu.debug 由于测试用例未运行而引发如下错误。

Timeout - Async callback was not invoked within the 120000ms timeout specified by jest.setTimeout.Error: Timeout - Async callback was not invoked within the 120000ms timeout specified by jest.setTimeout.

排毒安装：

npm install detox --save-dev

排毒初始化-r开玩笑

已创建包含三个文件的e2e文件夹，如下所示：

fristTest.spec.js

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

it('should have welcome screen', async () => {
    await expect(element(by.id('welcome'))).toBeVisible();
});

it('should show hello screen after tap', async () => {
    await element(by.id('hello_button')).tap();
    await expect(element(by.text('Hello'))).toBeVisible();
});

it('should show world screen after tap', async () => {
    await element(by.id('world_button')).tap();
    await expect(element(by.text('World!!!'))).toBeVisible();
});
});

config.json

{
    "setupTestFrameworkScriptFile": "./init.js",
    "testEnvironment": "node"
}

init.js

const detox = require('detox');
const config = require('../package.json').detox;
const adapter = require('detox/runners/jest/adapter');

jest.setTimeout(10000);
jasmine.getEnv().addReporter(adapter);

beforeAll(async () => {
    await detox.init(config);
});

beforeEach(async () => {
    await adapter.beforeEach();
});

afterAll(async () => {
    await adapter.afterAll();
    await detox.cleanup();
});
