Eclipse + Seam + TestNG Tricky

TestNG gives "Connection Refused" while running on Eclipse

While running TestNG in Eclipse there will always be 2 VMs involved: the VM of Eclipse and the VM running the tests. In order to update the plugin UI the 2 VMs are communicating over a port using a very simple string based protocol. The exception you are seeing is telling that the 2 VMs are not able to talk to each other. This is a weird exception that would translate into: there was impossible to open a communication port between the 2 VMs involved. Off hand, the cause may be: a bug in Eclipse/plugin or maybe a firewall/antivirus that blocks this.

TestNG/Seam reports ClassNotFoundException issues

This is mostly caused by Class Path configuration, also, Java 6 may be the cause, use Java 5!!

Could not find several required files

It seems that it does not like space in the path T_T, try to set the workspace to somewhere with NO space!! FUCK!

When running test case in Eclipse, TestNG complains bad version in .class file even Java 5 is used

java.lang.UnsupportedClassVersionError: Bad version number in .class file

Make sure everything is Java 5 compliant, such as:

• Project build path
• JAVA_HOME, JRE_HOME
• Java's in PATH (check by java -version)
• The Application Server (i.e. must be JDK5 compiled JBoss AS 5)
