Stripe Error : Call to a member function setLastResponse() on array

Are you mocking the call to stripe or hitting the live service in your tests?

You shouldn't be doing anything that hits the stripe api directly. Everything beyond your PaymentIntentRepository should be mocked.

This may be of help. https://medium.com/sprint-digital/mock-stripe-api-in-laravel-with-mockery-6ec578fb3eef

Can you post your test method?

It's mocked. Here is the test:

/**
 * @testdox Handle payment_intent.succeeded
 */
public function testHandlePaymentIntentSucceeded(): void
{
    /** @var \App\Models\Basket $basket */
    $basket = Basket::factory()->create();

    $this->mock(CreateOrder::class, function (MockInterface $mock) use ($basket) {
        $mock
            ->shouldReceive('handle')
            ->once()
            ->withArgs(function (Basket $basketArg, PaymentIntent $paymentIntent) use ($basket) {
                return $basketArg->is($basket) && $paymentIntent->id === 'pi_test';
            });
    });

    $this->mock(StripeClient::class);

    $this->sendWebhook([
        'type' => 'payment_intent.succeeded',
        'data' => [
            'object' => [
                'charges' => [
                    'object' => 'list',
                    'data' => [
                        [
                            'id' => 'ch_test',
                            'metadata' => [
                                'basket_id' => (string) $basket->getKey(),
                            ],
                            'object' => 'charge',
                            'status' => 'succeeded',
                        ],
                    ],
                ],
                'id' => 'pi_test',
                'object' => 'payment_intent',
            ],
        ],
    ])->assertSuccessful();
}

protected function sendWebhook(array $data = []): TestResponse
{
    return $this->withoutExceptionHandling()->postJson('/stripe/webhook', $data);
}

do you have any tests which hit that method that don't have the stripe bit mocked?

Ah yes I do. for example this one:

public function it_shows_product_in_checkout()
{
    $product = Product::factory()->create();

    $product->addToBasket(1);

    $this->get(route('order.create')) // $paymentIntents->createFromBasket($basket) called in here
        ->assertOk()
        ->assertViewIs('orders.create')
        ->assertSee($product->name)
        ->assertSee(Str::penceToPounds($product->price));
}

How would I mock the StripeClient here? I tired adding $this->mock(StripeClient::class) at the beginning of the method which throws this error:

Mockery\Exception\BadMethodCallException : Received Mockery_2_Stripe_StripeClient::request(), but no expectations were specified
