[英]Unit Testing Angular Service that uses $timeout with Jasmine's Mock Clock
[英]jasmine testing a mock service in an angular 1.5 controller
給出以下測試。
我如何確保兌現承諾並提供數據。
describe("component: FicaStatusComponent",
function () {
var fs;
beforeEach(function () {
module("aureus",
function ($provide) {
$provide.service("ficaService", function () {
this.status = function () {
return $q(function (resolve, reject) {
resolve([{ documentType: { id: 1 } }]);
});
}
})
});
});
beforeEach(inject(function (_$componentController_, _ficaService_) {
$componentController = _$componentController_;
fs = _ficaService_;
}));
it("should expose a `fica` object", function () {
console.log('should expose');
var bindings = {};
var ctrl = $componentController("ficaStatus", null, bindings);
expect(ctrl.fica).toBeDefined();
});
it("compliant with no documents should not be compliant",
function () {
var ctrl = $componentController("ficaStatus");
expect(ctrl.fica.length).toEqual(1);
});
}
);
沒有文件的第二項測試失敗。 長度為零。 另一個測試通過了,因此我實例化了正確的控制器,該屬性已定義。
模擬服務無法正確解析數據,可能是因為Promise
仍在執行中,或者根本沒有被調用。
這是該組件的控制器的實現:
var FicaStatusController = (function () {
function FicaStatusController($log, $loc, ficaService) {
var _this = this;
this.$log = $log;
this.$loc = $loc;
this.ficaService = ficaService;
this.fica = [];
this.ficaService.status(1234).then(function (_) { return _this.fica = _; });
}
該服務如下:
var FicaStatusService = (function () {
function FicaStatusService($log, $http) {
this.$log = $log;
this.$http = $http;
}
FicaStatusService.prototype.status = function (accountNumber) {
var url = "api/fica/status/" + accountNumber;
this.$log.log("status: " + url);
return this.$http
.get(url)
.then(function (_) { return _.data; });
};
return FicaStatusService;
}());
...
首先,您可以像這樣使用$ q:
this.status = function () {
return $q.when([{ documentType: { id: 1 } }]);
}
其次,使用$ scope。$ digest,$ rootScope。$ digest解決承諾。
var a = $q.when({test: 1});
expect(a.test === 1).toBe(false);
$rootScope.$digest();
expect(a.test === 1).toBe(true);
