javascript - Appium iOS获取上下文不起作用
<p><p>我正在开发一个 iOS React-Native 应用程序。现在我正在为登录功能进行集成测试。为了登录我们的应用程序，用户需要打开电子邮件并点击一个链接。</p>
<p>我想用 Appium 集成测试做什么:
- 打开 native 应用程序。
- 按应用程序中的按钮发送电子邮件
- 打开浏览器和gmail
- 查找电子邮件并单击链接登录
- 返回应用程序进行其余测试</p>
<p>但是，我在打开电子邮件时遇到了问题，我认为这是因为驱动程序的上下文有误。但是，当我尝试使用 <code>driver.contexts()</code> 函数获取可用上下文时，我只会收到一个错误并且根本没有上下文。 </p>
<p><strong>为什么 <code>driver.contexts()</code> 函数不起作用？我尝试做的事情合理吗？</strong></p>
<p>我的测试 stub 如下所示:</p>
<pre><code>import wd from 'wd'
import { config, port } from '../appiumConfig'
const driver = wd.promiseChainRemote('localhost', port)
describe('Login', () => {
beforeAll(async () => await driver.init(config))
afterAll(async () => await driver.quit())
it('Should get contexts', async () => {
await driver.contexts((err, handle) => {
if (err) { // Error!
console.log(err)
}
console.log(handle)
})
})
})
</code></pre>
<p>Appium 配置如下:</p>
<pre><code>"ios-emulator": {
"platformName": "iOS",
"platformVersion": "11.3",
"deviceName": "iPhone Simulator",
"app": "./ios/build/Build/Products/Release-iphonesimulator/myApp.app"
}
</code></pre>
<p>我得到的错误是:</p>
<blockquote>
<p>{"message":" Error response status: 13, , UnknownError -

<p><p>它对我来说非常适合原生应用程序</p>

</code></pre>
<p>您的日志状态错误 <code>ECONNREFUSED</code> 意味着您的 appium 服务已关闭，可能它在处理请求时崩溃了 -> 检查完整日志以了解发生了什么。</p>
<p>我想说这个问题很可能是因为您试图在同一个 session 中执行所有步骤(重用相同的驱动程序实例)。
尝试在单独的 session 中进行浏览器导航到 gmail，然后返回使用第一个继续进行应用程序测试。多个应用 session 开始使用 XCode 9，因此它可能会有所帮助。</p></p>
