At work I had to create some test data for a junit test. The function I’m testing expects a super abstract class to be passed in and I need to test the same function for bunch of child classes. I wish I could just pass in the parent class but since it’s abstract I cannot instantiate it. I wonder if there is a way using reflection so I can instantiate the class?? Since I could not find a way, I used the following:
public void testSomeFunction() throws Exception {
ParentData data1 = populate(ChildDataOne.class);
//..test..
ParentData data2 = populate(ChildDataTwo.class);
//..test..
}
private static ParentData populate(Class clazz) throws Exception {
ParentData data = clazz.newInstance();
data.setProperty1("1");
data.setProperty2("2");
data.setProperty3("3");
data.setProperty4("4");
data.setProperty5("5");
return data;
}
