Please help with simple JavaScript example

Hello there,

i try to create my first Appium Test and want to use JavaScript for the Appium Client to be used within some existing NodeJS project.

I followed the getting started instructions for a JS Client here
https://appium.io/docs/en/about-appium/getting-started/index.html1

Now i would like to adjust this example to start a pre installed app on my emulator instead of using “app” inside the caps. Is this possible?

The App is not starting, here´s the code i tried:

// javascript
const wdio = require('webdriverio');

// javascript
const opts = {
  port: 4723,
  desiredCapabilities: {
    platformName: "Android",
    platformVersion: "6.0",
    deviceName: "emulator-5554",
    //app: "/root/example/ApiDemos-debug.apk",
    appPackage: "com.whatsapp",
    appActivity: "com.whatsapp.HomeActivity",
    automationName: "UiAutomator2"
  }
};

const client = wdio.remote(opts);

// javascript
client
  .init()
  .click("~App")
  .click("~Alert Dialogs")
  .back()
  .back()
  .end();

Another problem is that i see absolutely no logs to the terminal after executing…

node mytest.js

If everything is set up correctly, you’ll see Appium begin spitting out lots of logs
