laravel 7 blade component public methods not working

[mohammadmojrian]

I have a problem with my Laravel project in using blade component.

When I define a new component and want to use "Component public Methods" to pass data to "view component blade file", I receive an error, "Undefined variable"

The component has been made by

php artisan make:component testc
has following codes:
component code

<?php

namespace App\View\Components;

use Illuminate\View\Component;

class testc extends Component
{
    /**
     * Create a new component instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Get the view / contents that represent the component.
     *
     * @return \Illuminate\View\View|string
     */
    public function render()
    {
        return view('components.testc');
    }

    public function test()
    {
        return 'test';
    }
}

view component blade file

<div>
    {{ $test }}
</div>

Error

Facade\Ignition\Exceptions\ViewException
Undefined variable: test (View: /../resources/views/components/testc.blade.php)

i try cache:clear view:clear and composer dump before

laravel version : 7.18.0
php version : 7.2.24

Your testc class name is wrong. It needs to start with an uppercase letter as the PSR-4 autoloading standard requires:

<?php

namespace App\View\Components;

use Illuminate\View\Component;

class Testc extends Component

thanks for your answer
but my component work correctly
and i edit my file name and class name to pass PSR-4 Standard
I have the same problem to pass any public methods to components blade file

I tried out your code and everything works fine for me:

            <div class="content">
                <div class="title m-b-md">
                    Laravel
                </div>

                <x-testc />

@driesvints
after create new component i have problem again :(
i create a new component /section/index/features and create a public methos to return array
in blade change code to loop a variable ( my function ) and try to print
use <x-section.index.features></x-section.index.features> and <x-section-index.features> not working agian :(
i thinks this conflicted with any bug or something...
because in my other projects is working well
