### Question:
BoxVerifierExtension extends DefaultComponentVerifierExtension { @Override protected Result verifyParameters(Map<String, Object> parameters) { ResultBuilder builder = ResultBuilder.withStatusAndScope(Result.Status.OK, Scope.PARAMETERS) .error(ResultErrorHelper.requiresOption("userName", parameters)) .error(ResultErrorHelper.requiresOption("userPassword", parameters)) .error(ResultErrorHelper.requiresOption("clientId", parameters)) .error(ResultErrorHelper.requiresOption("clientSecret", parameters)); return builder.build(); } protected  BoxVerifierExtension(String defaultScheme, CamelContext context);   }### Answer:
@Test public void verifyParameters() { Result result = verifier.verifyParameters(parameters); assertEquals(errorDescriptions(result), Result.Status.OK, result.getStatus()); }
