Test cases for multiple sheet

[FFasna]

I'm trying to write test cases for my export files, which are multiple sheets. I can see the file is downloaded, but it's empty and Content-Type is shown as empty.

it('user_can_download_invoices_export', function () {
    Excel::fake();
    $response = $this->get('/source/export');
    $response->assertStatus(200);

    Excel::assertDownloaded('sources.xlsx', function (SourceDocumentsTemplateExport $export) {
        // Assert that the correct export is downloaded.
        return $export->array();
    });
});

FAILED Tests\Feature\SourceTest > it user_can_download_invoices_export TypeError
App\Exports\Templates\SourceDocumentsTemplateExport::array(): Return value must be of type array, null returned

Here is my export class:

class SourceDocumentsTemplateExport implements FromArray, WithMultipleSheets
{
    protected $sheets;

    public function array(): array
    {
        return $this->sheets;
    }

    public function sheets(): array
    {
        $sheets = [
            new SourcesPrimarySheet(),
            new CompanyDropdown('name'),
            new CompanyDropdown('category'),
            new CompanyDropdown('type'),
            new CompanyDropdown('status'),
        ];

        return $sheets;
    }
}

Could anyone tell me how we test the multiple sheet exports?

Sounds like you want to do the following:

class SourceDocumentsTemplateExport implements WithMultipleSheets
{
    public function sheets(): array
    {
        return [
            new SourcesPrimarySheet(),
            new CompanyDropdown('name'),
            new CompanyDropdown('category'),
            new CompanyDropdown('type'),
            new CompanyDropdown('status'),
        ];
    }
}

it('user_can_download_invoices_export', function () {
    Excel::fake();
    $response = $this->get('/source/export');
    $response->assertStatus(200);

    Excel::assertDownloaded('sources.xlsx', function (SourceDocumentsTemplateExport $export) {
        // Assert that the correct export is downloaded.
        return count($export->sheets()) === 5;
    });
});

Thank you, this solved the issue and I can write more tests based on the sheets now.
