TestNG Error: Reference testng-impl-classpath not found

When we are running testng ant tasks we might get this error: 
"Reference testng-impl-classpath not found"


You should look at the testng.xml file you are using for testng to pick up your classes from!!!
Like mine has the following: 
















Now you should check if your classes mentioned in the file are found at the exact path..
I have a mistake in the path. My classes are found under Panels.LeftPanels.Barrel.TestBookBox
Thus the error.


So solution: Check if you have any mistake in the class path you mentioned!!!!

ssh connection refused on port 22

When we are trying to access another linux box using ssh we might get this error:
ssh error: connection refused on 22



Hit this command: ps aux | grep sshIf you get two entries which list sshd and ssh-agent then it means ssh is running on your machineKill those connectionsStart your ssh again


This should resolve the issue!!!!
If you have resolved it in any other way, please leave a comment. Thanks!

Working with User Defined Properties using ANT

Add the following to the build.xml: 



Now you can access the property from your program as 
String urlString = System.getProperty("url");


If you are using TestNG framework, then you should add the property to your ant task in the build.xml file as: 











To send this property from command line, you should send the property as 
-Durl=
