Simulates submission of a form using GET instead of POST.

Forms that use the GET method cannot be submitted with WebTestBase::drupalPostForm(), which explicitly uses POST to submit the form. So this method finds the form, verifies that it has input fields and a submit button matching the inputs to this method, and then calls WebTestBase::drupalGet() to simulate the form submission to the 'action' URL of the form (if set, or the current URL if not).

See WebTestBase::drupalPostForm() for more detailed documentation of the function parameters.

Parameters

string $path: Location of the form to be submitted: either a Drupal path, absolute path, or NULL to use the current page.

array $edit: Form field data to submit. Unlike drupalPostForm(), this does not support file uploads.

string $submit: Value of the submit button to submit clicking. Unlike drupalPostForm(), this does not support AJAX.

string $form_html_id: (optional) HTML ID of the form, to disambiguate.
