使用自定义功能将WDIO代码运行到特定位置

Question

我有一个本地移动设备实验室（就像Sauce一样）。我使用他们的客户端保留设备，并希望在该实验室中创建的Appium网址上运行代码

我厌倦了使用onPrepare函数进行保留并创建新功能，并将该功能传递给功能对象到WDIO conf文件。当我运行npm脚本时，它仅运行onPrepare函数，但不会创建t Appium est会话（尽管当我在本地托管Appium时，它可以很好地工作）

    onComplete: async function () {

Console log:

我想向WDIO驱动程序发送具有所需功能的正确URL /端口/路径
