我有一个简单的服务,我正在尝试单元测试.无论我尝试什么,searchService是一个未知的提供者,或者服务是空的(这足以使我的测试失败!!).
任何人都有洞察我可能做错了什么？
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 );
};
}
);
我正在尝试创建一个加载在searchService中的单元测试,以便我可以检查缓存的值：
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);
});
});
});
以下内容应该适用于没有参数的服务,也许这可以是一个起点：
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);
}));
});
});
