Laravel 8 : Trying to test a controller method thanks to JSON Get Testing but the route is not found

I'm getting this error:

Expected status code 200 but received 404. Failed asserting that 200 is identical to 404.

When I try to call it from my Unit Test:

<?php

namespace Tests\Unit;

use App\Models\Project;
use Tests\TestCase;

class ExampleTest extends TestCase
{

    public function testTakePlace()
    {
        $project = Project::factory()->make();

        $response = $this->getJson('controllerUserProject_takePlace', [
            'project_id' => $project->id,
        ]);

        $response
            ->assertStatus(200)
            ->assertJsonPath([
                'project.status' => Project::STATES['TO_BE_REPLIED'],
            ]);
    }
}

However, controllerUserProject_takePlace is correctly the name I gave to the route. Indeed, here is /routing/web.php:

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\TestConnections;

use App\Http\Controllers\ControllerUserProject;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/controllerUserProject_takePlace/projects/{project_id}', [ControllerUserProject::class, 'takePlace'])->name('controllerUserProject_takePlace');

The controller ControllerUserProject is correctly defined:

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;

class ControllerUserProject extends Controller
{
    public function takePlace(Request $request, $project_id)
    {
        return [
            'project_status' => Project::STATES['TO_BE_REPLIED']
        ];
    }
}

Do you know why the use of the route returns 404 (not found)?
