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:

  • manually upgrade chrome on your emulator/device
  • pick a newer emulator/device

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.
