framework: [5.2] problem with see method in InteractsWithPages.php

I used to be able to test API with post and see methods. The following code example uses post and see methods to check the HTML response but now it doesn’t work anymore. It is as if the post method doesn’t create a new HTML anymore through the see method.

public function testBasicExample()
{
    $this->post('/calculations', ['date' => '2016-01-10'])
         ->see('<td>5,000,000.00
                       </td>
                       <td>0.00
                       </td>');
}
