I have the following route (express) for which I'm writing an integration test.
Here's the code:
var q = require("q"),
request = require("request");
/*
Example of service wrapper that makes HTTP request.
*/
function getProducts() {
var deferred = q.defer();
request.get({uri : "http://localhost/some-service" }, function (e, r, body) {
deferred.resolve(JSON.parse(body));
});
return deferred.promise;
}
/*
The route
*/
exports.getProducts = function (request, response) {
getProducts()
.then(function (data) {
response.write(JSON.stringify(data));
response.end();
});
};
I want to test that all the components work together but with a fake HTTP response, so I am creating a stub for the request/http interactions.
I am using Chai, Sinon and Sinon-Chai and Mocha as the test runner.
Here's the test code:
var chai = require("chai"),
should = chai.should(),
sinon = require("sinon"),
sinonChai = require("sinon-chai"),
route = require("../routes"),
request = require("request");
chai.use(sinonChai);
describe("product service", function () {
before(function(done){
sinon
.stub(request, "get")
// change the text of product name to cause test failure.
.yields(null, null, JSON.stringify({ products: [{ name : "product name" }] }));
done();
});
after(function(done){
request.get.restore();
done();
});
it("should call product route and return expected resonse", function (done) {
var writeSpy = {},
response = {
write : function () {
writeSpy.should.have.been.calledWith("{\"products\":[{\"name\":\"product name\"}]}");
done();
}
};
writeSpy = sinon.spy(response, "write");
route.getProducts(null, response);
});
});
If the argument written to the response (response.write) matches the test passes ok. The issue is that when the test fails the failure message is:
"Error: timeout of 2000ms exceeded"
I've referenced this answer, however it doesn't resolve the problem.
How can I get this code to display the correct test name and the reason for failure?
NB A secondary question may be, could the way the response object is being asserted be improved upon?
