Testing methods and controllers with Laravel 5 [phpunit]

I am tring to make test for my project, could someone show me example how to write tests or give me some good video course to learn testing.

In my example I am tring to test this part:

public function getProjectsForUser(){
        if(Auth::user() -> admin_id == NULL){
            $this->id = Auth::user() -> id;
        }else{
            $this->id = Auth::user() -> admin_id;
        }
        $projects = User::findOrFail(Auth::user() -> id)->projects()->where('admin_id', '=', $this->id)->get();

        $role = User::findOrFail(Auth::user() -> id)->roles;

        $users = User::where('admin_id', '=', $this->id)->lists('name','id');

        return array('projects' => $projects,'users' => $users,'roles' => $role );
}

It was my model Project.php

Here is my PorojectController:

public function project(Project $projects){
            $this -> projects = $projects ->getProjectsForUser();
            return view('projects',$this -> projects);
        }

Here is my test to check if user logged...

public function testHome()
        {
            $this->be(User::find(1));
            $response = $this->call('GET', '/projects');
            //CHECK IF AUTH USER
            $this->assertTrue($response->isOk());

    }

Now I need to check if I get right values inside array, for $project, $role, $users.
