I want to test a specific function:
function initializeView() {
var deferred = $q.defer();
if(this.momentArray) {
core.listMoments(constants.BEST_MOMENT_PREFIX, '').then(function(moments) {
//Ommitted
deferred.resolve(moments);
}, function(error) {
console.log("ERROR");
deferred.reject(error);
});
}
else {
deferred.resolve();
}
return deferred.promise;
};
There is a function call within this one:
function listMoments(prefix, startAfter) {
// var deferred = $q.defer();
var promises = [];
return awsServices.getMoments(prefix, startAfter).then(function(moments) { //Mocked
console.log("getMoments Returned"); //This does not appear in the console
for(var i = 0; i < moments.length; i++) {
// moments[i].Key = constants.IMAGE_URL + moments[i].Key;
promises.push(getMomentMetaData(moments[i]));
}
return $q.all(promises);
});
};
This is the corresponding test function:
it('Should correctly initialize the view', function(done) {
spyOn(awsServices, 'getMoments').and.callFake(function() {
console.log("getMoments Has been mocked"); //This appears in the console
return $q.resolve(mock_moment);
});
service.initializeView().then(function() {
done();
})
});
The issue lies with the mock of 'getMoments' function in awsServices. It seems that although the function is being mocked successfully, the "then" part of the promise is not executing.
Hence, based on the console logs, it prints the 'getMoments Has been mocked' log but fails to print 'getMoments Returned'. Consequently, the function gets stuck in an infinite loop and my test eventually times out.
