Hello,
this request is not a Guice problem. This is a general problem in java. As
i understand your question, you would like reset a class variable on each
test method, but what do you mean with "class variable" in object oriented
programming class variable are defined attributes, that are the same value
on every object. in java you declarate this with static.
So if you mean static variables, than your goal is to reset this variable
value. But the problem is, the initialize of this variable classification
is on the first access of this class. That means if the class loader is
accessing the first time this class.
To reset this value you have some possiblilities. In general you have to
use reflection api. So you should set the value of this field manually on
each test method. in JUnit maybe in the setUp() method (@Before)
for example i make this to test the i18n support of my project:
final Class<Messages> messageClazz = Messages.class;
final Field resourceField = messageClazz.getDeclaredField("RESOURCE_BUNDLE"
);
final Field bundleField = messageClazz.getDeclaredField("BUNDLE_NAME");
resourceField.setAccessible(true);
bundleField.setAccessible(true);
final Field modifiersField = Field.class.getDeclaredField("modifiers");
modifiersField.setAccessible(true);
modifiersField.setInt(resourceField, resourceField.getModifiers() & ~
Modifier.FINAL);
Locale.setDefault(_currentLocale);
final ResourceBundle currentBundle = ResourceBundle.getBundle((String)
bundleField.get(null));
resourceField.set(null, currentBundle);
In guice you could reinitialize the injector instance on each test, so the
class variable will be reinitialize on every new injector. because guice
create an own class loader and create instance in this classloader. On new
injector object, another instances are available.
i hope i could you answering your question.
