Trying to run Selenium tests using Hudson - "Error: no display specified"
- by tputkonen
I'm trying to get Selenium tests to work when they are executed by Hudson, but I have not been successful so far. Hudson is running on Ubuntu, and Selenium is unable to open display.
Command I use for launching the build is:
mvn clean selenium:xvfb install
error log:

I've also tried to get it working by adding execution for xvfb, but also it failed.
