Testing PDFs

In your test, you can call the fake() method on the Pdf facade to fake the PDF generation. Because the PDF generation is faked, your tests will run much faster.

// in your test

use Spatie\LaravelPdf\Facades\Pdf;

beforeEach(function () {
    Pdf::fake();
});

##assertSaved

You can use the assertSaved method to assert that a PDF was saved with specific properties. You should pass it a callable which will received an instance of Spatie\LaravelPdf\PdfBuilder. If the callable returns true, the assertion will pass.

use Spatie\LaravelPdf\Facades\Pdf;
use Spatie\LaravelPdf\PdfBuilder;

Pdf::assertSaved(function (PdfBuilder $pdf) {
    return $pdf->downloadName === 'invoice.pdf'
        && str_contains($pdf->html, 'Your total for April is $10.00');
});

If you want to assert that a PDF was saved to a specific path, you accept the path as a second parameter of the callable.

use Spatie\LaravelPdf\Facades\Pdf;
use Spatie\LaravelPdf\PdfBuilder;

Pdf::assertSaved(function (PdfBuilder $pdf, string $path) {
    return $path === storage_path('invoices/invoice.pdf');
});

##assertRespondedWithPdf

The assertRespondedWithPdf method can be used to assert that a PDF was generated and returned as a response.

Imagine you have this route:

use Spatie\LaravelPdf\Facades\Pdf;

Route::get('download-invoice', function () {
    return pdf('pdf.invoice')->download('invoice-for-april-2022.pdf');
});

In your test for this route you can use the assertRespondedWithPdf to make sure that a PDF was generated and returned as a download. You can even make assertions on the content of the PDF.

use Spatie\LaravelPdf\Facades\Pdf;
use Spatie\LaravelPdf\PdfBuilder;

it('can download an invoice', function () {
    $this
        ->get('download-invoice')
        ->assertOk();
        
    Pdf::assertRespondedWithPdf(function (PdfBuilder $pdf) {
        return $pdf->downloadName === 'invoice-for-april-2022.pdf'
            && $pdf->isDownload()
            && str_contains($pdf->html, 'Your total for April is $10.00');
    });
});

##Simple assertion methods

Beside the methods listed above, there are a few simple assertion methods that can be used to assert that a PDF was generated. They are meant to test code that generated a single PDF. The assertions will pass if any of the generated PDFs match the assertion.

If your code generates multiple PDFs, it's better to use the assertSaved method.

##assertViewIs

You can use the assertViewIs method to assert that a PDF was generated using a specific view.

Pdf::assertViewIs('pdf.invoice');

##assertSee

You can use the assertSee method to assert that a PDF was generated that contains a given string.

Pdf::assertSee('Your total for April is $10.00');

You can pass an array of strings to assert that all of them are present in the PDF.

Pdf::assertSee([
    'Your total for April is $10.00', 
    'Your total for May is $20.00',
]);

##assertViewHas

You can use the assertViewHas method to assert that a PDF was generated that was passed a specific key in its view data.

Pdf::assertViewHas('invoice');

As a second parameter you can pass the expected value.

Pdf::assertViewHas('invoice', $invoice);

##assertSaved

You can use the assertSaved method to assert that a PDF was saved to the specified path.

Pdf::assertSaved(storage_path('invoices/invoice.pdf'));
