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

Why is this answer downvoted? seems like a valid alternative to me. Some reason why using
require is not desired?

@MondKin, I use require in my test files all the time to pull in necessary libraries and resources. I don't know why this was downvoted. I just upvoted.

I'd like to add that you need to use a trick when using require if you are trying to require a file that does not have the .js extension. The example above won't necessarily work as '.js' will be appended to the end and not be able to find
data.json.js. The workaround is to add a fake URL parameter like require('./data.json?test='). This will turn into data.json?test=.js which will still locate the file.

@RobertHenderson require('./data.json') works fine for me without your trick, but I see you were writing a couple of years ago.
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}

It looks like this requires jasmine-jquery library.
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);
});
