You can run specs with embark spec, it will run any files ending *_spec.js under spec/.

Embark includes a testing lib to fastly run & test your contracts in a EVM. To require Embark's Testing Module do:

EmbarkSpec = require('embark-framework').Tests

Afterwards you can initialize a contract and pass arguments to its contractor:

SimpleStorage = EmbarkSpec.request("SimpleStorage", [150]);

Embark will look for the contract at app/contracts/*, compile it and run it in a VM. You can then interact with the contract normally. e.g SimpleStorage.set(100)

A caveat at the moment is that the return values are represented as strings. So SimpleStorage.get() will return "100"

e.g

# spec/contracts/simple_storage_spec.js
EmbarkSpec = require('embark-framework').Tests;

describe("SimpleStorage", function() {
  beforeAll(function() {
    // equivalent to initializing SimpleStorage with param 150
    SimpleStorage = EmbarkSpec.request("SimpleStorage", [150]);
  });

  it("should set constructor value", function() {
    expect(SimpleStorage.storedData()).toEqual('150');
  });

  it("set storage value", function() {
    SimpleStorage.set(100);
    expect(SimpleStorage.get()).toEqual('100');
  });

})

Embark uses Jasmine by default, but you can use any testing framework you want.
