### Question:
BooleanParser implements ConfigurationParser { @Override public Set<Class> getResponsibleClasses() { Set<Class> responsibleClasses = new HashSet<>(); responsibleClasses.add(Boolean.class); responsibleClasses.add(boolean.class); return responsibleClasses; }  @Override Set<Class> getResponsibleClasses(); @Override Boolean parseValue(String value, Class targetType);  }### Answer:
@Test public void getResponsibleClasses() { Set<Class> responsibleClasses = parser.getResponsibleClasses(); assertTrue(responsibleClasses.contains(Boolean.class)); assertTrue(responsibleClasses.contains(boolean.class)); }
