How to handle context?

[djMax]

I want to use should in mocha. In those cases, I have some response objects (such as network responses) that I don't want to print out UNLESS something went wrong. I don't like doing "something".should.equal("foo", "Error from server: " + serverResponse). I'd rather do something LIKE:

should["response"] = serverResponse; "something".should.equal("foo", "Error from server");

and have it print out the context if an assert matches. I'm not wed to the particular syntax, just that you should be able to have a bunch of assertions without copying results every time. THoughts?

not sure I get it, you want should.js to support response-specific auto-messages? why not just create a little wrapper function around should (or assert)

[djMax]

Sure, just seems like something that would be globally useful. The goal is that there are things you might want to output when an assertion fails but NOT if it doesn't (over a set of assertions). So you need some sort of container for those messages.

@djMax can you write a concrete example with tests and expected output?

describe('something', function () { it('should call some server API', function () { request.post({url:"http://www.google.com"}, function (error, response, body) { should.not.exist(error); should.inspect(body); // This is what I'm asking for (something like it) so that IF an error happens now, it prints body body.indexOf("somestring").should.not.be.below(0); // lots more tests of characteristics of body would go here

   // Alternatively, it could be a closure type thing, though this feels odd
   should.inspect(body)(function () {
     body.indexOf("somestring").should.not.be.below(0);
   });
});

}); });
