[fw-general] How to simulate a file upload to test form

[Ralf Eggert]

Hi,

I want to test a form with PHPUnIt which contains several fields and a
file element. Here is the very simplified test case (simplified means I
left out a couple of form elements):

    public function testValidatingCorrectInput()
    {
        // create instance of form
        $form = new EmployerEditForm();

        // define input data
        $inputData = array(
            'employer_id'              => '1',
            'employer_type'            => 'standard',
            'employer_company'         => 'Musterfirma',
            'submit_employer_edit'     => 'submit_employer_edit',
        );

        // define expected erros
        $expectedErrors = array(
            'employer_id' => array(
            ),
            'employer_type' => array(
            ),
            'employer_company' => array(
            ),
            'employer_logo' => array(
            ),
            'submit_employer_edit' => array(
            ),
        );

        // check if form is valid
        $this->assertTrue($form->isValid($inputData));
    }

This test fails and when I check the form errors with $form->getErrors()
I get the result that employer_logo has an error called
"fileUploadErrorFileNotFound". I tried to mess around with $_FILES
before the test is run to simulare an uploaded file but then I get the
error "fileUploadErrorAttack". I also set $inputData['employer_logo'] to
the path of a test image, but then I get an exception:

  Zend_File_Transfer_Exception: "employer_logo" not found by
  file transfer adapter

So what is the best way to test the isValid() method of a form which
contains a file element?

Thanks and best regards,

Ralf
