> The default tests runner (if not specified) is {{BlockJUnit4ClassRunner}} its default behavior is to create a new instance of the test class for *each executed test method*. This can be changed by deriving an {{ExtendedBlockJUnit4ClassRunner}} and overriding its _createTest_ method:
> {code:java}
> public class ExtendedBlockJUnit4ClassRunner {
>     private final AtomicReference<Pair<Class<?>, Object>> testHolder = new AtomicReference<>();
> protected Object createTest() throws Exception {
>     Pair<Class<?>, Object> lastTest = testHolder.get();
>     Class<?> lastTestClass = (lastTest == null) ? null : lastTest.getLeft();
>     TestClass curTest = getTestClass():
>     Class<?> curTestClass = curTest.getJavaClass():
>     if (curTestClass == lastTestClass) {
>         return lastTest.getRight();
>     }
>     Object instance = curTest.getOnlyConstructor().newInstance();
>     testHolder.set(Pair.of(curTestClass, instance));
>     return instance;
> }
> {code}
