[Bigdata-developers] trac 704 fixed: tests using easy mock

[Jeremy J C. <jj...@sy...>]

Hi I have fixed trac 704 concerning ASK and JSON

Underlying problem was sesame support for this was missing. 
I added it to ConnegUtil with:



	static {
	// Work-around for sesame not handling ask and json (see trac 704)
		final BooleanQueryResultFormat askJsonFormat = BooleanQueryResultFormat.register("SPARQL/JSON","application/sparql-results+json","srj");
		BooleanQueryResultWriterRegistry.getInstance().add(new BooleanQueryResultWriterFactory(){

			@Override
			public BooleanQueryResultFormat getBooleanQueryResultFormat() {
				return askJsonFormat;
			}

			@Override
			public BooleanQueryResultWriter getWriter(final OutputStream out) {
				return new BooleanQueryResultWriter(){

					@Override
					public BooleanQueryResultFormat getBooleanQueryResultFormat() {
						return askJsonFormat;
					}

					@Override
					public void write(boolean arg0) throws IOException {
						String answer = "{ \"head\":{ } , \"boolean\": " +  Boolean.toString(arg0) + " }";
						out.write(answer.getBytes("utf-8"));
						
					}};
			}});
	}



The test framework additions allow mocking a HttpRequest and Responses to a servlet, to test for such protocol issues. I used easy mock 3.2, apache 2.0 license, to help do this.

I am running
com.bigdata.rdf.sail.TestAll
to verify

The changes are in a patch on the trac ticket, and can also be seen in Git at:
