javascript - 排毒“无法读取 null 的属性‘绑定’”错误

Question

我尝试将 Detox e2e 测试添加到我的 react 本机应用程序中，并且在尝试运行简单测试时遇到以下错误。

我只在应用程序的 iOS 端安装了 Detox。“detox build”命令完美执行。

以下是我项目中的重要文件。

包.json

  }
}
}
}

配置文件

{
"setupFilesAfterEnv": ["./init.js"],
"testEnvironment": "node",
"reporters": ["detox/runners/jest/streamlineReporter"],
"verbose": true
}

初始化.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');


jest.setTimeout(120000);

jasmine.getEnv().addReporter(adapter);

jasmine.getEnv().addReporter(specReporter);

beforeAll(async () => {
  await detox.init(config);
}, 300000);

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

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