### Question:
ReflectionHelper { public static Class<?> getClassForName(final String className) throws ClassNotFoundException { try { return Class.forName(className, true, Thread.currentThread().getContextClassLoader()); } catch (ClassNotFoundException e) { return Class.forName(className); } } private  ReflectionHelper(); static Class<?> getClassForName(final String className); static Class<?> getArrayType(final Class<?> type); static Field getDeclaredField(final Object bean, final String fieldName); static Object getFieldValue(final Object bean, final String fieldName); static Class<?> getGenericType(final Field field); static T newCollectionInstance(final Class<T> clazz); static T newInstance(final Class<T> clazz); static T newInstance(final String fullyQualifiedClassName, final Class<T> superType); static List<T> createInstances(final List<String> fullyQualifiedClassNames, final Class<T> superType); static void setFieldValue(final Object bean, final String fieldName, final Object value); static Set<Field> getDeclaredFieldsWithAnnotationRecursively(final Class<?> clazz,
                                                                        final Class<? extends Annotation> annotationClass); static T[] newArrayFromCollection(final Collection<?> collection, final Class<T> elementType);  }### Answer:
@Test public void getClassForNameReturnsObject() throws ClassNotFoundException { Class<?> clazz = ReflectionHelper.getClassForName(Object.class.getName()); assertThat(clazz).isSameAs(Object.class); }
@Test(expected = ClassNotFoundException.class) public void getClassForNameThrowsExceptionWhenClassNotFound() throws ClassNotFoundException { ReflectionHelper.getClassForName("NotExistent"); }
