回答1:

You can load an external json data file using require

var data = require('./data.json');
console.log(data);
// Your test cases goes here and you can use data object

回答2:

Set the path to find your file, in this case my file (staticData.json) is located under /test folder.

jasmine.getFixtures().fixturesPath = 'base/test/';
staticData= JSON.parse(jasmine.getFixtures().read("staticData.json"));

You have to add also the pattern in the karma.conf.js file, something like:

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

Do you want to read the JSON file from a webserver or a local file system? No one can give an example of loading from a local file system from Plunker, since it runs in a web browser and is denied access to the file system.

Here is an example of how to load a JSON file from disk in any Node.js program, this should work for Karma/Jasmine:

var fs = require('fs');
var filename = './test.json';

fs.readFile(filename, 'utf8', function (err, data) {
    if (err) {
        console.log('Error: ' + err);
        return;
    }

    data = JSON.parse(data);

    console.dir(data);
});
