在对补丁端点进行特性测试时，我在控制器更新方法中获得了新的雄辩示例，而不是所需的雄辩模型。在PurchaseTest.php中生成的雄辩模型没有通过路由模型绑定传递到PurchaseController.php。但当我通过浏览器使用路由时，路由工作正常。

网页. php

Route::name('admin.')->middleware(['admin'])->prefix('admin')->group(function () {
    Route::name('purchases.')->prefix('/purchases')->group(function () {
        Route::patch('/{purchase}/update', 'PurchaseController@update')->name('update');
    });
});

购买测试. php

class PurchaseTest extends TestCase
{
    use RefreshDatabase;
    use WithoutMiddleware;

    public function test_purchase_can_be_updated()
    {
        $purchase = Purchase::create([
            "item" => "tariqs item",
            "support" => "2022-09-09",
            "status" => PurchaseStatus::ACTIVE,
            "purchase_code" => "1234",
            "username" => "tariq",
            "user_id" => "1",
        ]);
        
        // $purchase model is not passing to controller through this patch request.
        $response = $this->patch(route('admin.purchases.update', compact('purchase')), [
            "item" => "tariqs item edit",
            "support" => "2022-09-09",
            "status" => PurchaseStatus::ACTIVE,
            "purchase_code" => "1234",
            "username" => "tariq",
        ]);

        $response->assertStatus(200);
    }
}

采购控制器. php

public function update(Request $request, Purchase $purchase)
    {
        dd($purchase, $request->all());  // here $purchase is a new instance of $purchase, not the desired $purchase model.

        $input = $request->validate([
            "item" => "required|string",
            "support" => "required|date_format:Y-m-d",
            "status" => "required|string",
            "purchase_code" => "required|string",
            "username" => "required|string",
        ]);

        if ($purchase->update($input)) {
            $purchases = Purchase::where('user_id', $purchase->user_id)->get();
            return response()->json(['success' => 'true', 'msg' => __("Purchase code successfully updated."), 'embed' => view('admin.misc.purchase-list', compact('purchases'))->render()]);
        }

        throw ValidationException::withMessages(['error' => __('Something went wrong.')]);
    }
