I have this specific JavaScript code
function hideGreenCarsFromView(greenCar) {
if (greenCar) {
var car = parkingCarTools.getContainerOfgreenCar(greenCar, sr.pageModel.garageData.cars);
if (car && car.greenCars && car.greenCars.length > 0) {
parkingCarTools.removegreenCarFromgreenCarsList(greenCar, car.greenCars);
}
}
if (car.greenCars && car.greenCars.length == 0) {
sr.showgreenCarsHeader = false;
}
};
In this code snippet I am removing the green cars I have in a list from the view.
To test this I have written a Jasmine test which looks like the following:
it('when green car is invalidLicensePlate, should not remove green car from view', function() {
//Arrange
var myGreenCars = undefined;
var expectedGreenCars = [{
licensePlateNumber: 1,
description: "BMW",
quantity: 1,
greencars: [{
licensePlateNumber: 4,
ownersNumber: 1,
description: 'vallicensePlateNumber green car 1',
quantity: 1
}, {
licensePlateNumber: 5,
ownersNumber: 1,
description: 'vallicensePlateNumber green car 2',
quantity: 2
}]
}, {
licensePlateNumber: 2,
description: "Mazda",
quantity: 3,
greencars: [{
licensePlateNumber: 6,
ownersNumber: 2,
description: 'vallicensePlateNumber green car 3',
quantity: 1
}, {
licensePlateNumber: 7,
ownersNumber: 2,
description: 'vallicensePlateNumber green car 4',
quantity: 2
}]
}, {
licensePlateNumber: 3,
description: "Toyota",
quantity: 1
}];
//Act
dut = compileDirective();
dut.removegreen carItemFromView(myGreenCars);
//Assert
expect(dut.pageModel.cartData.items.length).toBe(3);
expect(dut.pageModel.cartData.items).toEqual(expectedGreenCars);
expect(dut.pageModel.cartData.items[0].greencars.length).toBe(2);
expect(dut.pageModel.cartData.items[1].greencars.length).toBe(2);
});
My test fails at dut.removegreen carItemFromView(myGreenCars);
I get the
'undefined' in not an object (evaluating 'car.greenCars')
error.
What am I doing wrong here ? this is my first time doing Jasmine tests, I am a little lost, thank you in advance.
