Test-Driving JavaScript Applications

Integrate and Run

We need one final function that integrates all the functions together and for that, we need a few integration tests. Let’s start with the integration tests; you can also key these into the stockfetch-test.js file:

it(​'getPriceForTickers should report error for invalid file'​,
  ​function​(done) {
  ​var​ onError = ​function​(error) {
    expect(error).to.be.eql(​'Error reading file: InvalidFile'​);
    done();
  };
  ​var​ display = ​function​() {};

  stockfetch.getPriceForTickers(​'InvalidFile'​, display, onError);
});

it(​'getPriceForTickers should respond well for a valid file'​,
  ​function​(done) {
  ​var​ onError = sandbox.mock().never(); ...
