WebdriverIO can not create session to test Android emulator with Appium

I am using Visual Studio Code and WDIO with Appium to test Android on emulator by Android Studio, but I can not run Appium for some reason. However Android home and Java home has been set and Appium Doctor confirms necessary dependencies are completed, no fix needed.

I have tried with Appium stand-alone and from Command too.

Wit Appium standalone the ERROR log is the below:

ERROR webdriver: Request failed with status 500 due to session not created: Unable to create session from {
"desiredCapabilities": {
"platformName": "android",
"appium:deviceName": "Pixel",
"appium:platformVersion": "10.0",
"appium:app": "\u002fUsers\u002fzsolt\u002fappium_js\u002fApiDemos-debug.apk"

If I add ['appium'] to services in wdio.config.js the ERROR log is the below, though Appium stand-alone is shut:

ERROR @wdio/cli:utils: A service failed in the 'onPrepare' hook
Error: Appium exited before timeout (exit code: 2)
[HTTP] Could not start REST http interface listener. The requested port may already be in use. Please make sure there is no other instance of this server running already.

at ChildProcess.EventEmitter.emit (domain.js:482:12)
at Process.ChildProcess._handle.onexit (internal/child_process.js:275:12)

This is my wdio.config.js file with using Appium stand-alone:

exports.config = {
    
    runner: 'local',
    port: 4723,
    
    specs: [
        './test/specs/**/*.js'
    ],
    
    exclude: [
        // 'path/to/excluded/files'
    ],
    
    maxInstances: 10,
    
    capabilities: [{
        platformName: 'android',
        'appium:deviceName': 'Pixel',
        'appium:platformVersion': '10.0',
        'appium:app': '/Users/zsolt/appium_js/ApiDemos-debug.apk'
        
    }],
    
    logLevel: 'error',
   
    bail: 0,
    
    baseUrl: 'http://localhost',
    
    waitforTimeout: 10000,
    
    connectionRetryTimeout: 120000,
    
    connectionRetryCount: 3,
    
    services: ['selenium-standalone', 
    /*['appium', {
        //command : 'appium'
    }]*/],
    
    reporters: ['spec'],
 
    mochaOpts: {
        ui: 'bdd',
        timeout: 60000
    },

These are my:

"devDependencies": {
   "@wdio/local-runner": "^6.1.11",
   "@wdio/mocha-framework": "^6.1.8",
   "@wdio/selenium-standalone-service": "^6.0.16",
   "@wdio/spec-reporter": "^6.1.9",
   "@wdio/sync": "^6.1.8",
   "appium": "^1.17.1"

Has anybody an idea what am I doing wrong?

Check that the file you are running is inside the correct folder when you do the 'npx wdio'.

Welcome to Stack-overflow!

Below is my configuration and I believe you are missing some important details.

{
  platformName: 'Android',
  maxInstances: 1,
  'appium:deviceName': 'Device Name',
  'appium:platformVersion': '8'
  'appium:orientation': 'PORTRAIT',
  'appium:app': 'Path to App',
  'appium:automationName': 'UiAutomator2',
  'appium:noReset': true,
  'appium:newCommandTimeout': 240,
}

There are boilerplates from maintainers themselves here.

Also you need to install the Appium service:

$ npm i @wdio/appium-service --save-dev

Finally check in your wdio.conf.js:

port: 4723, // default appium port
services: [
    [
        'appium',
        {
            args: {
            },
            command: 'appium'
        }
    ]
],

I have played with the boilerplates and was able to run the tests on android emulator through Appium finally.

I have then compared the differences in conf.js and figured out, the below is needed to execute the test.

services:[
        [
            'appium',
            {
            // For options see
            // https://github.com/webdriverio/webdriverio/tree/master/packages/wdio-appium-service
                args: {
                // For arguments see
                // https://github.com/webdriverio/webdriverio/tree/master/packages/wdio-appium-service
                },
                command: 'appium',
            },
        ],
    ],

Interesting but actually the test runs with only the below capabilites too:

capabilities: [{
        platformName: 'Android',
        'appium:deviceName': 'Pixel 2',
        'appium:app': join(process.cwd(), './ApiDemos/ApiDemos-debug.apk'),

    }],

When I execute the test it logs almost the same error messages as before though at the end of the execution it runs the test on the emulator. I did not use the Appium Desktop app.

Not perfect but works...

I guess this issue has been sorted out.

Cheers
