测试自定义路由模型绑定

Question

我正在尝试测试实现 \Illuminate\Contracts\Routing\UrlRoutable 的自定义 class，但无法调用 resolveRouteBinding 方法。

<?php

namespace Tests\Unit;

use Illuminate\Support\Facades\Route;
use Tests\TestCase;

class BindingExampleClassTest extends TestCase
{
    function test_invoke_resolve_route_binding_method()
    {
        Route::get('/invoke-route-binding/{binding}', function (BindingExampleClass $binding) {
            dd($binding);
        });

        $this->get('/invoke-route-binding/1');
    }
}

class BindingExampleClass implements \Illuminate\Contracts\Routing\UrlRoutable
{
    public $id;

    public function resolveRouteBinding($value, $field = null)
    {
        $this->id = $value;
    }

    public function getRouteKey()
    {
        // TODO: Implement getRouteKey() method.
    }

    public function getRouteKeyName()
    {
        // TODO: Implement getRouteKeyName() method.
    }

    public function resolveChildRouteBinding($childType, $value, $field)
    {
        // TODO: Implement resolveChildRouteBinding() method.
    }
}

dd 响应为 BindingExampleClass，id 仍然为空。

在测试函数中注册路由将不包含任何中间件。在 Laravel 中使用路由模型绑定时，必须在路由器实例中定义 \Illuminate\Routing\Middleware\SubstituteBindings::class 中间件。

Route::get('/invoke-route-binding/{binding}', function (BindingExampleClass $binding) {
    dd($binding);
})->middleware(\Illuminate\Routing\Middleware\SubstituteBindings::class);
