我有一项服务,我想测试它的功能。但是,我不知道如何模拟在该服务中的每个函数内使用的服务函数。我想检查一下,如果调用了正确的URL。
这是我的服务:
angular.module("myModule").service('myService', MyService);
MyService.$inject = ['$http'];
function MyService($http) {
var myService = this;
myService.request = function (reqType, url, headers, requestBody, fnc, fncFail) {
$http(createRequest(reqType, point, headers, requestBody)).then(function (response) {
if (typeof fnc == 'function') {
fnc(response.data);
}
}, function (response) {
if (typeof fncFail == 'function') {
fncFail(response);
}
});
};
myService.getInfo = function (id, fnc, fncFail) {
myService.request("GET", "myURL", {"Accept":"application/json"}, null, function (data) {
fnc(data);
}, fncFail);
};
现在我的测试套件的片段:
beforeEach(inject(function ($injector) {
service = $injector.get("myService");
httpBackend = $injector.get("$httpBackend");
http = $injector.get("$http");
}));
it("function getInfo is called with the correct URL", function () {
spyOn(http, 'get').and.callThrough();
myService.getInfo(id, fnc, fncFail);
expect(http.get).toHaveBeenCalledWith("myurl");
httpBackend.flush();
});
我不确定,如果这是测试我的方法“getInfo”的正确方法,因为它调用了其他服务函数(“request”)。
答案 0 :(得分:2)
使用$httpBackend
进行XHR调用。使用以下afterEach
块,如果未进行调用,则测试将失败。
afterEach(function() {
httpBackend.verifyNoOutstandingExpectation();
httpBackend.verifyNoOutstandingRequest();
});
it("function getInfo is called with the correct URL", function () {
httpBackend.expect('GET', "myurl").respond(200, {mocked: "response"});
myService.getInfo(id, fnc, fncFail);
httpBackend.flush();
});
