問題描述

我正在嘗試完成 Jasmine 測試(使用 Karma 和 IntelliJ 13)來驗證 JSON 文件.理想情況下，我的測試將簡單地將 JSON 文件加載到數據對象中，然后讓我解析以檢查有效的格式和數據.我不需要在之前或之后驗證函數，也不需要針對服務器進行測試.

I'm trying to accomplish a Jasmine test (using Karma and IntelliJ 13) to validate JSON files. Ideally, my test would simply load a JSON file into a data object, then let me parse through to check for valid formatting and data. I don't need to validate functions before or after, nor do I need to test against a server.

我的基本設置是這樣的:

My basic setup is like this:

it("should load an external file", function(){
var asyncCallComplete, result,
            _this = this;
        // asyncCallComplete is set to true when the ajax call is complete
        asyncCallComplete = false;

        // result stores the result of the successful ajax call
        result = null;

        // SECTION 1 - call asynchronous function
        runs(function() {
            return $.ajax('/test/config.json', {
                type: 'GET',
                success: function(data) {
                    asyncCallComplete = true;
                    result = data;
                },
                error: function() {
                    asyncCallComplete = true;
                }
            });
        });

        // SECTION 2 - wait for the asynchronous call to complete
        waitsFor(function() {
            return asyncCallComplete !== false;
        }, "async to complete");

        // SECTION 3 - perform tests
        return runs(function() {
            return expect(result).not.toBeNull();
        });
}

問題是無論我使用什么路徑，我都會收到 404 錯誤并且文件不會加載.我嘗試使用此測試服務從遠程服務器加載外部 JSON 結果:

The problem is that no matter what path I use, I get a 404 error and the file won't load. I've tried loading an external JSON result from a remote server using this test service:

http://date.jsontest.com/

這行得通.

我的測試文件名為/test/mySpec.js，我的 karma.conf.js 文件位于根目錄中.我已經將 JSON 文件移動到所有這些位置，但沒有運氣.我做錯了什么?

My test file is named /test/mySpec.js and my karma.conf.js file is on the root. I have moved around the JSON file to all of these locations with no luck. What am I doing wrong?

更新答案:

根據下面的答案，我將此添加到我的 karma.conf.js:

Per the answer below, I added this to my karma.conf.js:

// fixtures
{ pattern: 'test/*.json',
    watched: true,
    served:  true,
    included: false
}

然后，我這樣寫了我的測試:

Then, I wrote my test this way:

    var json:any;
    it("should load a fixture", function () {
        jasmine.getFixtures().fixturesPath = "base/test/"
        var f = readFixtures("registration.json");
        json = JSON.parse(f);
        expect(json).toBeDefined();

    })

    it("should have a title", function () {
        expect(json.title).toNotBe(null);
    })
    etc...

它通過了.

推薦答案

您是否通過 karma.config.js 提供 JSON 文件?

Are you serving the JSON file via karma.config.js?

您可以通過夾具提供 JSON 文件:

You can serve JSON files via fixture:

files: [
      // angular 
      'angular.min.js',
      'angular-route.js',
      'angular-mocks.js',

      // jasmine jquery helper
     'jquery-1.10.2.min.js',
     'jasmine-jquery.js',

      //  app
      '../../public/js/app.js',

      // tests
      '*-spec.js',

      // JSON fixture
      { pattern:  '/test/*.json',
        watched:  true,
        served:   true,
        included: false }
    ],
