Dingo $this->delete not working

`public function it_deletes_a_fruit()
{
$user = factory(\App\User::class)->create(['password'=> bcrypt('foo')]);

$fruit = \App\Fruit::create(['name' => 'peache', 'color' => 'peache', 'weight' => 125, 'delicious' => true]);

$response = $this->delete('api/fruits/' . $fruit->id, [], $this->headers($user));

$response->assertStatus(204);
}

}`

for don't worry about the **$fruit** and **$this->headers**
Why would this method not work?
