Testing wizards

On this page we'll show you a few tips on how to test wizard steps created with this package. For explanation purposes, consider an example wizard called CheckoutWizardComponent. It has the following steps:

• CartStepComponent: Displays the products in the user's cart.
• DeliveryAddressStepComponent: Allows the user to enter their delivery address.
• ConfirmOrderStepComponent: Displays the order details and allows the user to confirm the order.

##Testing a wizard step without state

The first step of our checkout wizard is a simple step that doesn't require any state. It only displays the products in the user's cart. To test this step, we can use the following test:

session()->put('cart', [
    ['name' => 'Candle', 'price' => 400],
    ['name' => 'Chocolate', 'price' => 150],
]);

CheckoutWizardComponent::testStep(CartStepComponent::class)
    ->assertSuccessful()
    ->assertSee('Items in your cart')
    ->assertSee('Candle')
    ->assertSee('Chocolate');

The above test will assert that the step is shown successfully, and that it displays the products in the cart.

##Testing a wizard step with state

You may need to test a wizard step that requires some state from a previous step. As an example, consider the last step of our checkout wizard.

CheckoutWizardComponent::testStep(ConfirmOrderStepComponent::class, [
        'wizard.delivery-address-step-component' => [
            'street' => '1818 Sherman Street',
            'city' => 'Hope',
            'state' => 'Kansas',
            'zip' => '67451',
            'deliveryDate' => '2022-01-12', // Wednesday
        ],
    ])
    ->assertSuccessful()
    ->assertSee('Please confirm your order')
    ->assertSee('Delivery Address: 1818 Sherman Street, Hope, Kansas, 67451')
    ->assertSee('Delivery on Wednesday, 12th January 2022')
    ->call('confirmOrder');
    
// Assert that the order is created and other expectations...
expect(Order::count())->toBe(1);

In the above test, we pass the state required by the ConfirmOrderStepComponent as an array. In this case, it is the delivery address that the user entered in the previous step. We are then able to assert whether the text is displayed properly and call the confirmOrder method on the Step to submit the order.
