我的 $resource-wrapping 服务有一个非常简单的单元测试。我已经模拟并设置了 httpBackend 以返回包含七个项目的数组。当我运行测试时，它报告返回了 4 个项目，而不是 7 个：

函数 (a1, a2, a3, a4) { ... }

预计 4 为 7。

以下是我的服务和规格

=== 服务 ===

/* original 
angular.module('TeamSportApp')
.factory('LedgerService', function ($resource) {
    var Ledgers =  $resource("/rest/api", { id: '@id'},
        {
            allLedgers : { method: 'GET', isArray: true},
            postTransaction : { method: 'POST'},
            removeTransaction : { method: 'DELETE'}
        });
    return Ledgers;
})*/

/* Fixed */
    .factory('LedgerService', function ($resource) {
    var Ledgers =  $resource("/rest/api/:id", { id: '@id' },
        {
            allLedgers : { method: 'GET', isArray: true},
            postTransaction : { method: 'POST'},
            removeTransaction : { method: 'DELETE'}
        });
    return Ledgers;
})

})

=== 规格 ===

 var ledgerArray = [
 {id:1, name:"Master Ledger"},
 {id:2, name:"User1 Ledger"},
 {id:3, name:"User2 Ledger"},
 {id:4, name:"User3 Ledger"},
 {id:5, name:"User4 Ledger"},
 {id:6, name:"User5 Ledger"},
 {id:7, name:"User6 Ledger"}
 ];
 ddescribe('Ledger service test', function(){
 var ledgers, httpBackend;
 beforeEach(module('TeamSportApp','ngResource'));

 beforeEach(inject(function ($injector) {
     ledgers = $injector.get("LedgerService");
     httpBackend = $injector.get("$httpBackend");
 }));

 afterEach (function () {
     httpBackend.verifyNoOutstandingExpectation ();
     httpBackend.verifyNoOutstandingRequest ();
 });

 /* ORIGINAL ERROR 
 it('gets a list of ledgers', function() {
     httpBackend.when('/rest/api').respond(ledgerArray);
     var result = ledgers.allLedgers;
     console.log(result);
     expect(result.length).toBe(4);
     //httpBackend.flush();
 });*/

 /* All fixed using angular1.2.14 per [this][1] */
     it('gets a list of ledgers', function() {
     httpBackend.expectGET('/rest/api').respond(ledgerArray);
     var result = ledgers.allLedgers();
     httpBackend.flush();
     expect(result.length).toBe(7);
 });

 it('gets a single ledger', function() {
     httpBackend.expectGET('/rest/api/2').respond(singleLedger);
     var result = ledgers.get({id:2});
     httpBackend.flush();
     console.log(result);
     expect(result.name).toBe(singleLedger.name);
 });

});

尝试这个：

服务：

.factory('LedgerService', function ($resource) {
    var Ledgers =  $resource("/rest/api/:id", { id: '@id'},
        {
            allLedgers : { method: 'GET', isArray: true},
            postTransaction : { method: 'POST'},
            removeTransaction : { method: 'DELETE'}
        });
    return Ledgers;
});

测试：

it('gets a list of ledgers', function() {
    httpBackend.expect('/rest/api/').respond(ledgerArray);
    var result = ledgers.allLedgers();
    httpBackend.flush();
    expect(result.length).toBe(7);
});
