How to do Junit test for interace method

Question

public static void setObjectMapper() {
    Unirest.setObjectMapper(new ObjectMapper() {
        private com.fasterxml.jackson.databind.ObjectMapper jacksonObjectMapper = new com.fasterxml.jackson.databind.ObjectMapper();

        @Override
        public <T> T readValue(String value, Class<T> valueType) {
            try {
                return jacksonObjectMapper.readValue(value, valueType);
            } catch (JsonMappingException e) {
                
            } catch (IOException e1) {
                
            }
        }

        @Override
        public String writeValue(Object value) {
            try {
                return jacksonObjectMapper.writeValueAsString(value);
            } catch (JsonProcessingException e) {
                
            }
        }
    });
}

Here I want to write a JUnit test code to cover the complete code. How to call readValue() and writeValue() method here.
