AAA: Arrange a test

• Mock base model with "real" data from your API
• Define your own data (if you're starting from scratch)

describe('Given check-in flow', function () {  
  it('should list the checked-in segments', function() {
    var firstFlightOnly = [];
    var lastFlightAfterFirst = [];
    var arrangeFirstFlight = _.cloneDeep(segments);
    var arrangeLastFlight = _.cloneDeep(segments);

    // set last flight not available for check-in
    arrangeFirstFlight[1].IsSegmentCheckInAvailable = false;
    arrangeFirstFlight[1].PaxSegments[0].HasCheckedIn = false;
    arrangeFirstFlight[1].PaxSegments[1].HasCheckedIn = false;
    arrangeFirstFlight[1].PaxSegments[2].HasCheckedIn = false;

    // set first flight to already checked-in
    arrangeLastFlight[0].IsSegmentCheckInAvailable = false;
    arrangeLastFlight[0].PaxSegments[0].HasCheckedIn = true;
    arrangeLastFlight[0].PaxSegments[1].HasCheckedIn = true;
    arrangeLastFlight[0].PaxSegments[2].HasCheckedIn = true;

    // set some people checked-in on last flight
    arrangeLastFlight[1].IsSegmentCheckInAvailable = true;
    arrangeLastFlight[1].PaxSegments[0].HasCheckedIn = true;
    arrangeLastFlight[1].PaxSegments[1].HasCheckedIn = true;
    arrangeLastFlight[1].PaxSegments[2].HasCheckedIn = false;
  });
});

AAA: Act on test data

• Tweak your base data to simulate a scenario
• Fake anything that fails (it's just a test)

describe('Given check-in flow', function () {  
  it('should list the checked-in segments', function() {
    // ... already arranged data...

    // act on the data so a new model is made 
    _.each(arrangeFirstFlight, function(segment){
      firstFlightOnly.push(new SegmentModelWithPaxInfo(
        segment,
        mockBoarding.booking.Passengers
      ));
    });

    // act on the data so another model is made, different to the last
    _.each(arrangeLastFlight, function(segment){
      lastFlightAfterFirst.push(new SegmentModelWithPaxInfo(
        segment,
        mockBoarding.booking.Passengers
      ));
    });
  });
});

AAA: Assert the results

• Test the results of your actions
• Properties should be defined
• Values should be parsed in your code correctly

describe('Given check-in flow', function () {  
  it('should list the checked-in segments', function() {
    // ... already arranged data...

    // ... already acted models...

    // prove aboth flights with passengers are shown
    expect(allFlights[0].availablePaxList.length).toBeGreaterThan(0);
    expect(allFlights[0].isCheckingIn).toBe(true);
    expect(allFlights[1].availablePaxList.length).toBeGreaterThan(0);
    expect(allFlights[1].isCheckingIn).toBe(true);

    // prove only the first flight is shown
    expect(firstFlightOnly[0].availablePaxList.length).not.toBe(0);
    expect(firstFlightOnly[0].isCheckingIn).toBe(true);
    expect(firstFlightOnly[1].availablePaxList.length).toBe(0);
    expect(firstFlightOnly[1].isCheckingIn).toBe(false);

    // prove only the last flight is shown
    expect(lastFlightAfterFirst[0].availablePaxList.length).toBe(3);
    expect(lastFlightAfterFirst[0].isCheckingIn).toBe(false);
    expect(lastFlightAfterFirst[1].availablePaxList.length).toBeGreaterThan(0);
    expect(lastFlightAfterFirst[1].availablePaxList.length).toBe(2);
    expect(lastFlightAfterFirst[1].isCheckingIn).toBe(true);
  });
});
