Behat pressButton not working in laravel 5

This is the tutorial by Jeoffery Way that I am testing

This is the scenario that I am trying to test

Scenario: Adding a new school
When I add a new school with "Narendra School" "This is a cool school"
Then I should see "Add School"
And a school is created

This is my feature context file,

/**
* @When I add a new school with :arg1 :arg2
*/
public function iAddANewSchoolWith($name , $description )
{
    $this->visit('school/create');
    $this->fillField( 'name', $name );
    $this->fillField( 'description', $description );
    $this->pressButton('register');
}

/**
* @Then a school is created
*/
public function aSchoolIsCreated()
{
   $school = School::all();
   PHPUnit::assertEquals($school->isEmpty(), false );
}

This is my html code

<form method="post">
<h2>Add School</h2>

    <input type="hidden" name="_token" value="{!! Session::getToken() !!}"/>

    <input type="text" name="name" placeholder="Name">
    <textarea name="description" placeholder="Description"></textarea>
    <button name="register">Register</button>
</form>

This is the controller method that i am using to create the object

function create( ) {

   if ( \Request::isMethod( 'post' ) ) {

     $this->school->add( \Input::all() );// I am using a repository and dependency injection so this code is fine, it will add a school
   }

   return view('school::school.add');
}

When I hit the url, fill the form and hit register in the browser, I save a new school but when I run the test, I cannot seem to create the school. The test is running I can see the html when I do a printLastResponse()

Feature: Testing
    In order to teach Behat
    As a teacher
    I want to add a new school

  Scenario: Adding a new school                                            # features\example.feature:6
    When I add a new school with "Narendra School" "This is a cool school" # FeatureContext::iAddANewSchoolWith()
    Then I should see "Add School"                                         # FeatureContext::assertPageContainsText()
    And a school is created                                                # FeatureContext::aSchoolIsCreated()
      Failed asserting that false matches expected true.
