I took the selenium4j project and turned it into a maven plugin for those who want to take the html test cases and automatically have them run with your maven test phase. You can also separate the tests out using a profile override with surefire.
Readme is here: https://github.com/willwarren/selenium-maven-plugin
The short version of the readme:
Converts this folder structure:
./src/test/selenium
|-signin
|-TestLoginGoodPasswordSmoke.html
|-TestLoginBadPasswordSmoke.html
|-selenium4j.properties
Into
./src/test/java
|-signin
|-firefox
|-TestLoginGoodPasswordSmoke.java
|-TestLoginBadPasswordSmoke.java
This is only tested on windows with Firefox and Chrome.
I couldn't get the IE version to pass a test, but I'm new to selenium so hopefully, if you're a selenium guru, you can get past this.
