I have a simple service that I am trying to unit test. No matter what I try, either the searchService is an unknown provider, or service is null (which oddly enough won't cause my test to fail!!).
Anyone have an insight on what I might be doing wrong??
angular.module('app').service('searchService', function( $q, _ ) { // _ is lodash
var cache = [
{
id: "current",
name: "Current",
description: "Search current data"
},
{
id: "historical",
name: "Historical",
description: "Search historical data"
}
];
this.getSearchOptions = function() {
var deferred = $q.defer();
deferred.resolve( angular.copy( cache ) );
return( deferred.promise );
};
this.getSearchOptionsByID = function( id ) {
var deferred = $q.defer();
var searchOption = _.findWithProperty( cache, "id", id );
if ( searchOption ) {
deferred.resolve( angular.copy( searchOption ) );
} else {
deferred.reject();
}
return( deferred.promise );
};
}
);
I am trying to create a unit test that loads in the searchService so I can check the cached values:
describe("Unit: Testing Services", function() {
describe("Search Service:", function() {
var service = null;
beforeEach(function() {
angular.module('app').service('_');
});
// I've also tried the commented out code below
//beforeEach(inject(function(searchService) {
//this.service = searchService;
//}));
//it('should contain an searchService', invoke(function(service) {
it('should contain an searchService', function(searchService) {
expect(searchService).not.to.equal(null);
});
it('should contain two search options', function(searchService) {
expect(searchService.getSearchOptions()).to.equal(2);
});
});
});
The following should work for a service without parameter, maybe this can be a starting point:
describe("Unit: Testing Services", function() {
describe("Search Service:", function() {
beforeEach(function() {
angular.module('app');
});
it('should contain a searchService',
inject(function(searchService) {
expect(searchService).not.to.equal(null);
}));
it('should contain two search options',
inject(function(searchService) {
expect(searchService.getSearchOptions()).to.equal(2);
}));
});
});
