Hi Yong, Could you provide some pointers for adding methods(not class level) to a test suite in JUNIT4..?
how can write test cases for the private method using junit test3.2
It is possible to test private methods in your class by different ways. An alternative solution could be to use/implement Java Reflection API.Something like this :
Method theMethod = targetClass.getDeclaredMethod(methodName, argClasses);
theMethod.setAccessible(true);
return theMethod.invoke(targetObject, argObjects);
Or take a look at this http://code.google.com/p/powermock/wiki/BypassEncapsulation
good luck:)
Unit test unable to test private method.
nice
Minimalist and useful
Thank you
These tutorials are really helpful. Thank you Mkyong.
