javascript - Testing requireJS methods async with Jasmine -


i trying test function requires module using jasmine , requirejs. here dummy code:

define("testmodule", function() {     return 123; }); var test = function() {     require(['testmodule'], function(testmodule) {         return testmodule + 1;     }); } describe("async requirejs test", function() {     it("should works", function() {         expect(test()).tobe(124);     }); });

it fails, because async method. how can perform test it?

note: dont want change code, tests describe function.

for testing of asynchronous stuff check runs(), waits() , waitsfor():

https://github.com/pivotal/jasmine/wiki/asynchronous-specs

though way looks bit ugly me, therefore consider following options.

1. i'd recommend try jasmine.async allows write asynchronous test cases in way:

// run async expectation async.it("did stuff", function(done) {     // simulate async code:     settimeout(function() {         expect(1).tobe(1);         // async stuff done, , spec asserted         done();     }); });

2. can run tests inside require's callback:

require([     'testmodule',     'anothertestmodule' ], function(testmodule, anothertestmodule) {      describe('my great modules', function() {          describe('testmodule', function() {             it('should defined', function() {                 expect(testmodule).tobedefined();             });         });          describe('anothertestmodule', function() {             it('should defined', function() {                 expect(anotertestmodule).tobedefined();             });         });     }); });

3. point guess code not working you're expecting:

var test = function() {     require(['testmodule'], function(testmodule) {         return testmodule + 1;     }); };

because if call test(), won't return testmodule + 1.
