Testing methods returning promise using jasmine - angularjs

Question

I am using jasmine & karma to test my angular app. I have a service as follows
app.service('demo1', function( $http ){
this.send = function(){
return $http({
url: 'someurl'
});
}
});
The response is mocked using ngMockE2E.
My jasmine spec is as follows:
describe('Testing asynchronus', function(){
var demoService;
beforeEach(function(){
module('app');
inject(function( demo1 ){
demoService = demo1
});
});
it('Should be able to test promise', function(){
demoService.send().then(function( data ){
expect(data.status).toBe(true);
});
});
});
Now the problem is, the expect is not executing. the test being passed every time, no matter what the value of data.status is. I need help on how to test these kinds of scenarios? Thanks in advance.
Real code:
describe("Testing MetaService", function(){
var _entityMeta_, metaService, scope;
beforeEach(function(){
console.log( '---------------------- Starting Meta Service fetchEntityMeta Test ---------------------------' );
module(APP_MODULE_NAME);
inject(function(_entityMeta_, _metaService_, $rootScope){
metaService = _metaService_;
entityMeta = _entityMeta_;
scope = $rootScope.$new();
});
});
afterEach(function(){
console.log( '---------------------- Ending Meta Service fetchEntityMeta Test ---------------------------' );
});
// Giving mock data from entityMeta.person as input
it("Should have a valid structure", function($rootScope){
console.log( '////////////////////////////////////////////' );
metaService.fetchEntityMeta('person').then(function( data ){
console.log( data );
expect(data.type).toBe('object');
expect(data.properties.length).toBeGreaterThan(0);
expect(data.definitions.length).toBeGreaterThan(0);
});
});
});
I am getting following error:
Error: Timeout - Async callback was not invoked within timeout specified
by jasmine.DEFAULT_TIMEOUT_INTERVAL.

Answer 1

try to add
beforeEach(module('app'));
under the describe

Answer 2

If you're using Jasmine 2, the argument to the callback passed to it is supposed to be a done function called when the test finished. (The test runner will time out if it is never called.)
(See the official doc here, or one of many blog posts.)
I don't really understand why you pass $rootScope in this case, but the error message looks like a complain because the done function (which happens to be named $rootScope here) has not be called.
This might work :
// Giving mock data from entityMeta.person as input
it("Should have a valid structure", function(done){
console.log( '////////////////////////////////////////////' );
metaService.fetchEntityMeta('person').then(function( data ){
console.log( data );
expect(data.type).toBe('object');
expect(data.properties.length).toBeGreaterThan(0);
expect(data.definitions.length).toBeGreaterThan(0);
done();
}, function (e) {
// The promise was not resolved, this is most likely an
// implementation error. Let's fail the test !
throw new Error(e);
});
});
If the then part is never called, the done function will not either, an you'll get the timeout error you're seeing right now.
