### Question:
Converter { protected final boolean isSuitable(Convert ann) { return ((ann != null) && !ann.ignore()); } Converter(Class dataClass); Class getDataClass();  }### Answer:
@Test public void isSuitable() throws Exception { Converter converter = new TestConverter(SamplePojo.class); assertFalse(converter.isSuitable(null)); assertFalse(converter.isSuitable(SamplePojo.class.getDeclaredField("ignoreString").getDeclaredAnnotation(Convert.class))); assertTrue(converter.isSuitable(SamplePojo.class.getDeclaredField("name").getDeclaredAnnotation(Convert.class))); }
