I get the error No Chromedriver found that can automate Chrome '##.#.####'

When trying to automate an Android webview in an app or the chrome browser it could be that you get the below error.

Failed: An unknown server-side error occurred while processing the command. Original error: No Chromedriver found that can automate Chrome '55.0.2883'. See https://github.com/appium/appium/blob/master/docs/en/writing-running-appium/web/chromedriver.md for more details.

The solution is to:

  • use an older version of ChromeDriver
  • manually upgrade chrome on your emulator/device
  • pick a newer emulator/device

Use an older version of ChromeDriver

Go to the link that is provided in the log, see here, follow the steps and download the version you need to have. Then provide the path to the downloaded ChromeDriver by adding the following to your command:

$ npm run android.app -- --appium.args.chromedriverExecutable="./chromeDriver/chromedriver"

The appium.args.chromedriverExecutable needs to refer to the location where the ChromeDriver is downloaded.

Manually update chrome

Execute the following steps to install Chrome on an Android emulator

  • Download a Chrome APK from APKMirror, check which processor is used in the Emulator (ARM or X86, X86 is faster).
  • Open the Emulator
  • Install the chrome.apk from the folder where it is saved with the following command adb install chrome.apk.
[100%] /data/local/tmp/chrome.apk
       	pkg: /data/local/tmp/chrome.apk
Success
  • When the message Success is shown Chrome is installed on the device.

iOS tests fail

Issue:

Typing text into an input text element on an iOS simulator with webdriver.io and Appium is causing an error like this

An unknown server-side error occurred while processing the command. Original error: An unknown server-side error occurred while processing the command.

The result is a failing test.

The command

The command is very simple, just this $('~accessibilityLabel').setValue('Why are you failing?')

The cause

After diving into the logs of webdriver.io, see webdriver.io.log, and Appium, see appium.log, I saw out that Appium was telling me the following

Got response with status 200: {"value":"Error Domain=com.facebook.WebDriverAgent Code=1 \"Keyboard is not present\" UserInfo={NSLocalizedDescription=Keyboard is not present}","sessionId":"15326722-C363-4CA0-B4D8-899E9077F830","status":13}

Solution

The solution is simple. iOS needs an activated keyboard. Go to Simulator > Hardware > Keyboard > Toggle software keyboard, enable the software keyboard and the problem will be gone.
