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.
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();
});
}
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:
And this works.
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?
UPDATE WITH ANSWER:
Per the answer below, I added this to my karma.conf.js:
// fixtures
{ pattern: 'test/*.json',
watched: true,
served: true,
included: false
}
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...
And it passes.
Are you serving the JSON file via karma.config.js?
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 }
],
Serving JSON via the fixture is the easiest but because of our setup we couldn't do that easily so I wrote an alternative helper function:
bower install karma-read-json
Put karma-read-json.js in your Karma files, Example:
files = [ ... 'bower_components/karma-read-json/karma-read-json.js', ... ]
Make sure your JSON is being served by Karma, Example:
files = [ ... {pattern: 'json/**/*.json', included: false}, ... ]
Use the readJSON
function in your tests. Example:
var valid_respond = readJSON('json/foobar.json'); $httpBackend.whenGET(/.*/).respond(valid_respond);
If you are trying to load a HTML file and want to avoid using jasmine-jquery , you may take advantage of the karma-ng-html2js-preprocessor .
In your karma.conf.js :
// generate js files from html templates
preprocessors: {
'resources/*.html': 'ng-html2js'
},
files: [
...
'resources/*.html'
],
plugins: [
...
'karma-ng-html2js-preprocessor'
],
In your jasmine spec :
beforeEach(module('resources/fragment.html'));
var $templateCache;
beforeEach(inject(function (_$templateCache_) {
$templateCache = _$templateCache_;
}));
describe('some test', function () {
it('should do something', function () {
// --> load the fragment.html content from the template cache <--
var fragment = $templateCache.get('resources/fragment.html');
expect(fragment).toBe(...);
});
});
Have you tried simply requiring the json file and storing it as a global variable in your test?
I'm developing an Angular2 project right now (using the Angular CLI), and with this setup it works:
// On the very beginning of the file let mockConfig = require('./test/config.json');
