laravel 5.8.7 Page expired (419)

I am submitting a POST request from form and it shows 419 | page expired.

Blade.php:

<form action="<?php echo action('TestsController@store'); ?>" method="post">

Route:

Route::resource('tests', 'TestsController');

Controller:

public function store(Request $request) {
        echo "something something";
}
