After completing the installtion I wrote a sample test case and I got below error message and I cannot run any testng anotations testcases

Java.lang.nullpointerexception .

    Please add the complete Exception. Installing unsigned content is most likely unrelated to your error. Without your code and/or a stacktrace we can't do much to help you. – Calon Dec 08 '15 at 06:27
