Testing a file upload to a form in a Behat feature file - symfony

Question

I am quite new to writing Behat test suites and I am currently trying to flesh out my existing feature file with an added test to test an uploaded file.
This is what I have come up with so far.
Scenario: Submitting a valid asset form and uploading a file
When I submit a asset form with values:
| name | type | position | active | file |
| St Andrews Release | image | 1 | 1 | /web/images/product/icon/default.jpg |
Then the form should be valid
And the entity form entity should have the following values
| name | type | position | active | file |
| St Andrews Release | image | 1 | 1 | /web/images/product/icon/default.jpg |
Failed asserting that null matches expected '/web/images/product/icon/default.jpg'.
And the entity form entity should be persisted correctly
This is the method handling the scenario:
/**
* #When I submit a asset form with values:
*/
public function iSubmitAssetFormWithValues(TableNode $table)
{
$data = $table->getColumnsHash()[0];
$this->form = $this->submitTheForm('crmpicco.asset.type', $this->entity, $data);
}
The submitTheForm method returns a Symfony\Component\Form\FormInterface.
Am I along the right lines? I am currently getting an error:
Failed asserting that null matches expected
'/web/images/product/swatch/default.jpg'.

I suggest you to create a dedicated folder structure for files which will be used in behat tests right in your application root because tests and the files used in tests must be consistent for all developers. I sometimes see people writing tests to upload files that exist on their local desktop:) My desktop and your desktop would be different hence reason the test would fail.
Structure
football #your application name/root
build
dummy
document
hello.doc
world.xls
image
test.jpg
behat.yml
Apart from other common setting, you must define file_path.
....
....
default:
extensions:
Behat\MinkExtension\Extension:
files_path: %behat.paths.base%/build/dummy/
....
....
Example Gherkin scenario
Feature: I can upload a file which is stored in my generic "dummy" folder
Scenario: I can upload image
Given I am on "/"
When I attach the file "image/test.jpg" to "league_flag"
And I press "Submit"
Then I should see "Succeeded."
