How can I properly get the errors in unit testing laravel as well as disable csrf checks?

I'm trying to test my post method in the controller. The method definition is something like :

    public function store(Request $request)
    {
        $article = new Article;

        $article->id = $request->input('article_id');
        $article->title = $request->input('title');
        $article->body = $request->input('body');
        return response(["success"], 200);
    }

I've created a test which just stores the data and checks if the response is 200. Please also show me how can I make this test better new to testing. But I'm getting 404 error I don't know what is the error. How can I display the errors what are the setting I need to configure? Test:

public function test_post_new_article(){
        $article = factory(Article::class)->make();
        $this->call('POST', 'article', [
            '_token' => csrf_token(),
            'article_id' => 6,
            'title'=>"hey",
            'body' => "this is a body"
        ])->assertStatus(200);
    }

phpunit error:

There was 1 failure:

1) Tests\Unit\ExampleTest::test_post_new_article
Expected status code 200 but received 404.
Failed asserting that false is true.
