【中文标题】获取 ReferenceError：在 react-native ios 上运行 detox 测试时未定义设备

【英文标题】：Getting ReferenceError: device is not defined when running detox test on react-native ios

【发布时间】：2020-03-09 08:18:10

【问题描述】：

我正在尝试将排毒测试添加到工作的 react-native 应用程序中，但在运行 detox test 时出现错误 这是错误消息：

detox test
detox[45074] INFO:  [test.js] configuration="ios.sim.debug" reportSpecs=true DETOX_START_TIMESTAMP=1573653557623 node_modules/.bin/jest --config e2e/config.json '--testNamePattern=^((?!:android:).)*$' --maxWorkers 1 "e2e"
● Validation Warning:

  Unknown option "setupFilesAfterEnv" with value ["./init.js"] was found.
  This is probably a typing mistake. Fixing it will remove this message.

detox[45074] ERROR: [cli.js] Error: Command failed: node_modules/.bin/jest 
--config e2e/config.json '--testNamePattern=^((?!:android:).)*$' --maxWorke
rs 1 "e2e"

这是我在 package.json 中的排毒配置：

"detox": 
    "configurations": 
      "ios.sim.debug": 
        "binaryPath": "ios/build/Build/Products/Debug-iphonesimulator/MdcIos.app",
        "build": "xcodebuild -workspace ios/MdcIos.xcworkspace -scheme MdcIos -configuration Debug -sdk iphonesimulator -derivedDataPath ios/build",
        "type": "ios.simulator",
        "device": 
          "type": "iPhone 11"
        
      
    ,
    "test-runner": "jest"
  

还有 e2e 文件夹中的 config.json：

    "setupFilesAfterEnv": ["./init.js"],
    "testEnvironment": "node",
    "reporters": ["detox/runners/jest/streamlineReporter"],
    "verbose": true,
    "transform": 
        "^.+\\.js$": "<rootDir>/../node_modules/react-native/jest/preprocessor.js"
    

最后是 e2e 中的 init.js：

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

// Set the default timeout
jest.setTimeout(120000);
jasmine.getEnv().addReporter(adapter);

// This takes care of generating status logs on a per-spec basis. By default, jest only reports at file-level.
// This is strictly optional.
jasmine.getEnv().addReporter(specReporter);

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

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

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

谢谢！

【参考方案1】：

我发现了问题； package.json 中 detox 配置中的 binaryPath 不好。

"binaryPath": "ios/build/Build/Products/Debug-iphonesimulator/APP_NAME_WAS_FALSE.app"

【参考方案2】：

运行adb devices命令并检查设备ID并将ID赋予package.json中的名称

"detox": 
    "configurations": 
      "ios.sim.debug": 
        "binaryPath": "ios/build/Build/Products/Debug-iphonesimulator/MdcIos.app",
        "build": "xcodebuild -workspace ios/MdcIos.xcworkspace -scheme MdcIos -configuration Debug -sdk iphonesimulator -derivedDataPath ios/build",
        "type": "ios.simulator",
        "name" : 520084b3b6ef7473(device id),
        "device": 
          "type": "iPhone 11"
        
      
    ,
    "test-runner": "jest"
