i'm using stubs write tests http request function such
// api.js var https = require('https'); function httpsget(domain, options, parameters) var deferred = q.defer(); var request = https.request(options, function(res) { var resbody = ''; res.on('data', function(data) { resbody += data; }); res.on('end', function() { if (resbody.length > 0) { try { var response = json.parse(resbody); if(response.error) { var errorstring = domain; for(var key in parameters){ errorstring += '\n\t' + key + ' - ' + parameters[key]; } deferred.reject(new error(errorstring + '\n' + response.error.code + ' - ' + response.error.message + ' - ' + response.error.reference)); } deferred.resolve(response); } catch(err) { deferred.reject(new error('error: response not json ' + domain)); } } else { deferred.reject(new error('response body of ' + domain + ' https call empty.')); } }); }); request.on('error', function(error) { deferred.reject(new error('error: ' + error)); }); request.end(); } return deferred.promise; } module.exports = { httpsget: httpsget }; how able test request.on('error', function() {}) statement? i'm trying using mocha, stubs , streams , don't feel i'm understanding @ all. can't seem create erroneous request leads statement.
try this:
var assert = require('assert'); describe('httpsget functional tests', function () { it('should catch error', function (done) { httpsget('', {}) // don't want resolve. .then(function () { done('expected invocation reject'); }) // expect rejection. .catch(function (err) { // console.log(err); assert(/econnrefused/.test(err.message), 'should error'); done(); }) // in case still have error. .catch(done); }); }); all need trigger old error in http request.
to honest though, i'd swap using request because handles of low level stuff you. can use nock provide fake responses test.
