Angular tests based on Karma and Jasmine (ongoing updates)

Recently more interested in front-end testing, especially the Nodejs + Karma + Jasmine test for angular. Look around, make a record, intermittent updates.

< a > Test Angular's Service1 with Jasmine. Throw the code First:

var app = Angular.module (' Application ', []);

App.factory (' MyService ', function () {var service = {};    Service.one = 1;    Service.two = 2; return service;});

2. How to test this angular service?

• Using Angular.injector, call the application Module to find the service. Then it's the function of the test service.

Describe (' MyService test ', function () {Describe (' when I call Myservice.one ', function () {It (' returns 1 ', Functio            N () {var $injector = angular.injector ([' Application ']);            var myservice = $injector. Get (' MyService ');        Expect (Myservice.one). toequal (1); })    })});

3. The results are as follows:

Because I ran a different test, so.

4. Another way to test the service

Use ' Invoke ' to pass the service to a function

Describe (' Myservice test2 ',  function () {    describe (' when i call  Myservice.one ',  function () {        it (' returns 1 ',  function () {            var mytestfunction  = function (Aservice) {                 expect ( aService.one ). Toequal (1);             }             Mytestfunction. $inject  = [  ' MyService '  ];             var myinjector = angular.injector ([  ' Application '  ]);             myinjector.invoke ( myTestFunction  );      &Nbsp;  })     }); 

5. Add an easier way:

Beforeeach is Jasmine's grammar, which runs before it ().

It is important to note that the inject function is not a ANGULARJS standard package, it is in the Ngmock module, and only work with Jasmine.

Describe (' MyService test3 ', function () {Describe (' when I call Myservice.one ', function () {Beforeeach (module (' App        Lication '));        It (' returns 1 ', Inject (function (MyService) {///parameter name is the service name expect (Myservice.one). toequal (1); }))    })});
