Problems running Protractor on a Windows Jenkins Slave Node

Question

I'm getting an issue while trying to run Protractor on IE11 on a Windows Jenkins Slave Node.

When I connect by remote desktop, I'm able to run Protractor with no issues. However, when I try to run Protractor from Jenkins I run into this issue:

[launcher] Error: UnknownError: JavaScript error (WARNING: The server did not provide any stacktrace information)

[launcher] Process exited with error code 100

This is weird, because I can run the same tests using any other browsers. Here are some things I tried:

• Made sure that Jenkins is using the same account as the one I'm logging in.
• Followed the steps on this blog: http://elgalu.github.io/2014/run-protractor-against-internet-explorer-vm/
• Changed the protected settings, zoom level and registry key as per this website: https://code.google.com/p/selenium/wiki/InternetExplorerDriver
• Tried using the x86 version of the IEDriverServer

Is there anything that I am missing?

Answer 1

I found out that reading documentation is a good thing :) https://code.google.com/p/selenium/wiki/InternetExplorerDriver

Read the configuring section

For IE 11 only, you will need to set a registry entry on the target computer so that the driver can maintain a connection to the instance of Internet Explorer it creates. For 32-bit Windows installations, the key you must examine in the registry editor is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE. For 64-bit Windows installations, the key is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE. Please note that the FEATURE_BFCACHE subkey may or may not be present, and should be created if it is not present. Important: Inside this key, create a DWORD value named iexplore.exe with the value of 0.

Worked for me...
