ReflectionTestUtils: Methods for changing values of attributes

[alpkaanaksu]

Is your feature request related to a problem? Please describe.
Sometimes I want to change the values of private attributes while testing student code. There is no ReflectionTestUtils method to do that.

Describe the solution you'd like
A new method (e.g. setValueForNonPublicAttribute, setValueForAttribute...) in the ReflectionTestUtils, which can also find and change an attribute even if it is defined in one of the superclasses.

Describe alternatives you've considered
I created a method myself.

public static void setValueForNonPublicAttribute(Object objectToModify, String attributeName, Object attributeValueToSet) {
        Class cls = objectToModify.getClass();
        do {
            try {
                Field field = cls.getDeclaredField(attributeName);
                field.trySetAccessible();
                field.set(objectToModify, attributeValueToSet);
                return;
            } catch (NoSuchFieldException e) {
                cls = cls.getSuperclass();
            } catch (Exception e) {
                fail("In " + objectToModify.getClass().getSimpleName() + ", " + attributeName + " can not be set to " + attributeValueToSet + ".");
            }
        } while (cls != null);
        fail("Could not find the attribute " + attributeName + " in class " + objectToModify.getClass().getSimpleName() + "! Make sure it exists and check for typos.");
    }
