How to send a POST request to codeception using a button?

Question

Yii

There is a page with the following button

<a href="/user/delete?id=1" data-method="post" id="mybutton"></a>

When you click on it, the browser sends a request /user/delete?id=1using the POST method. Then some action is performed on the server, and in response it returns a redirect back to the page with the button ( /user)
I'm trying to write a functional test for the above button. Now he looks like this

public function deleteUser(\FunctionalTester $I)
    {
        $I->amOnRoute('user');
        $I->see('myuser_stay');
        $I->see('myuser_delete');

        $I->click('#mybutton');

        $I->see('myuser_stay');
        $I->dontSee('myuser_delete');
    }

The deletion of the user should happen here myuser_delete, but not the user myuser_stay.
I'm trying to run the test, it crashes with an error on the line :$I->see('myuser_stay');

Apparently, for some reason, Codeception tries to send a GET request to , ignoring the buttons. Questions: 1) Why is data-method ignored? 2) How to fix it? Of course, you can use , and send a request directly, bypassing the button, but as for me, this is a crutch. /user/delete?id=1data-method
$I->sendAjaxPostRequest()

Answer 1

Perhaps the problem is that the attribute data-methodis processed by JS, which does not work in functional tests, respectively, and is data-methodignored .
Acceptance tests pass this moment normally?
