Laravel & Mockery: module for testing update method without hitting the database

Ok, so I'm pretty new to both unit testing, mocking, and laravel. I'm trying to unit test my resource controller, but I'm stuck with the update function. Not sure if I am doing something wrong or just thinking wrong.

Here's my controller:

class BooksController extends \BaseController {

    // Change template.
    protected $books;

    public function __construct(Book $books)
    {
        $this->books = $books;
    }

    /**
     * Store a newly created book in storage.
     *
     * @return Response
     */
    public function store()
    {
        $data       = Input::except(array('_token'));
        $validator  = Validator::make($data, Book::$rules);

        if($validator->fails())
        {
            return Redirect::route('books.create')
                ->withErrors($validator->errors())
                ->withInput();
        }

        $this->books->create($data);

        return Redirect::route('books.index');
    }

    /**
     * Update the specified book in storage.
     *
     * @param  int  $id
     * @return Response
     */
    public function update($id)
    {
        $book       = $this->books->findOrFail($id);
        $data       = Input::except(array('_token', '_method'));
        $validator = Validator::make($data, Book::$rules);

        if($validator->fails())
        {
            // Change template.
            return Redirect::route('books.edit', $id)->withErrors($validator->errors())->withInput();
        }

        $book->update($data);

        return Redirect::route('books.show', $id);
    }
}

      

        
        
        
      

    

And here are my tests:

public function testStore()
{
    // Add title to Input to pass validation.
    Input::replace(array('title' => 'asd', 'content' => ''));

    // Use the mock object to avoid database hitting.
    $this->mock
        ->shouldReceive('create')
        ->once()
        ->andReturn('truthy');

    // Pass along input to the store function.
    $this->action('POST', 'books.store', null, Input::all());

    $this->assertRedirectedTo('books');
}

public function testUpdate()
{
    Input::replace(array('title' => 'Test', 'content' => 'new content'));

    $this->mock->shouldReceive('findOrFail')->once()->andReturn(new Book());
    $this->mock->shouldReceive('update')->once()->andReturn('truthy');

    $this->action('PUT', 'books.update', 1, Input::all());      

    $this->assertRedirectedTo('books/1');
}

      

        
        
        
      

    

The problem is, when I do it like this, I am getting Mockery\Exception\InvalidCountException: Method update() from Mockery_0_Book should be called exactly 1 times but called 0 times.

the due $book->update($data)

in my controller. If I changed it to $this->books->update($data)

, it would be mocked correctly and the database would not be affected, but when using the function from the frontend, it would update all my entries.

I guess I just want to know how to mock $book-object properly

.

Am I clear enough? Let me know otherwise. Thank!
