I have an AngularJS app set up with tests using Karma+Jasmine. I have a function I want to test that takes a large JSON object, converts it to a format that's more consumable by the rest of the app, and returns that converted object. That's it.
For my tests, I'd like you have separate JSON files (*.json) with mock JSON content only--no script. For the test, I'd like to be able to load the JSON file in and pump the object into the function I'm testing.
I know I can embed the JSON within a mock factory as described here: http://dailyjs.com/2013/05/16/angularjs-5/ but I really want the JSON to not be contained within script--just straight JSON files.
I've tried a few things but I'm fairly noob in this area. First, I set up my Karma to include my JSON file just to see what it would do:
files = [
...
'mock-data/**/*.json'
...
]
This resulted in:
Chrome 27.0 (Mac) ERROR
Uncaught SyntaxError: Unexpected token :
at /Users/aaron/p4workspace4/depot/sitecatalyst/branches/anomaly_detection/client/anomaly-detection/mock-data/two-metrics-with-anomalies.json:2
So then I changed it to just serve the files and not "include" them:
files = [
...
{ pattern: 'mock-data/**/*.json', included: false }
...
]
Now that they're only served, I thought I'd try to load in the file using $http from within my spec:
$http('mock-data/two-metrics-with-anomalies.json')
When I ran the spec I received:
Error: Unexpected request: GET mock-data/two-metrics-with-anomalies.json
Which in my understanding means it expects a mocked response from $httpBackend. So...at this point I didn't know how to load the file using Angular utilities so I thought I'd try jQuery to see if I could at least get that to work:
$.getJSON('mock-data/two-metrics-with-anomalies.json').done(function(data) {
console.log(data);
}).fail(function(response) {
console.log(response);
});
This results in:
Chrome 27.0 (Mac) LOG: { readyState: 4,
responseText: 'NOT FOUND',
status: 404,
statusText: 'Not Found' }
I inspect this request in Charles and it's making a request to
/mock-data/two-metrics-with-anomalies.json
Whereas the rest of the files I've configured to be "included" by Karma are being requested at, for example:
/base/src/app.js
Apparently Karma's setting up some sort of base directory to serve the files from. So for kicks I changed my jquery data request to
$.getJSON('base/mock-data/two-metrics-with-anomalies.json')...
And it works! But now I feel dirty and need to take a shower. Help me feel clean again.
