Examples of com.google.common.testing.NullPointerTester

com.google.common.testing.NullPointerTester
A test utility that verifies that your methods throw {@link NullPointerException} or {@link UnsupportedOperationException} whenever anyof their parameters are null. To use it, you must first provide valid default values for the parameter types used by the class. @author Kevin Bourrillion @since Guava release 10
