问题 I've just starting working with Node, and I've been following along with various tutorials. I've created an Express app, and setup Mongoose and Jasmine. How can I configure my specs so that I can: create models, automatically clean them up after each spec use a different database for creating test objects (say myapp_test) do this in a way that is as DRY as possible, i.e. not creating a before / after block with the teardown for each describe block ? 回答1: I'll try to answer you. Create models,

问题 I have a function that calls the geolocator and i don't know how to test this function. I've tried spying on the geolocator and returning fake data but with no success, the original function is still used and so i would have to wait and i couldn't use mock data. // this doesn't work var navigator_spy = spyOn( navigator.geolocation, 'getCurrentPosition' ).andReturn( { coords : { latitude : 63, longitude : 143 } } ); How can I do this? 回答1: When you call the geolocation code, it looks like this

unit testing angular service, beforeEach inject doesn't execute

由 牧云@^-^@ 提交于 2019-12-08 19:54:26
I'm trying to write unit tests for an angular service with jasmine/karma. I have a similar service test, which works just fine. But this one has some additional dependencies, is in a different module and just doesn't find the service with the inject. The service looks something like this. bService is in the same module, but commonFactory and commonService are in another module, say commonModule . (function () { 'use strict'; angular .module('myService') .service('aService', aService); aService.$inject = [ 'commonFactory', 'commonService' 'bService' ]; function aService ( commonFactory,

How to actually reset $httpBackend expectations?

由 生来就可爱ヽ(ⅴ＜●) 提交于 2019-12-08 19:08:45
问题 I've tried and tried to get this to work. The documentation is terse, at best: resetExpectations(); - Resets all request expectations, but preserves all backend definitions. Typically, you would call resetExpectations during a multiple-phase test when you want to reuse the same instance of $httpBackend mock. Every time my second request is called, my result always has the first result's data. Check out this fiddle http://jsfiddle.net/tbwn1gt0/2/ where I reset the expectations after the first

问题 I want do something before all tests, then after? What is the best way to organize my code? For example: backup some variables -> clear them -> test something -> restore backups. 'beforeEach' and 'afterEach' are too expencive. Thanks! 回答1: A pretty simple solution: describe("all o' my tests", function() { it("setup for all tests", function() { setItUp(); }); describe("actual test suite", function() { }); it("tear down for all tests", function() { cleanItUp(); }); }); This has the advantage
