Laravel 5.1测试：收到“响应不是视图”错误

Question

I'm writting a unit test for a Laravel 5.1 controller, but having problem while trying to test search method:

<?php

use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;

class HomeControllerTest extends TestCase
{
    /**
     * A basic test example.
     *
     * @return void
     */
    public function testGetIndex(){

     $response = $this->call('GET', '/');

     $this->assertEquals(200, $response->getStatusCode());

     $this->assertViewHas(['menu_highlight',
      'page_title',
      'meta_description',
      'featured_reviews',
      'featured_categories',
      'images',
      'reviews']);

   }

   public function testGetSearch(){

    $response = $this->call('GET', '/search?search_terms=test');

    $this->assertEquals(200, $response->getStatusCode());

/* problem arises bellow: */

    $this->assertViewHas(['page_title',
      'meta_description',
      'products',
      'reviews',
      'brands',
      'images',
      'categories',
      'review_reporting_reasons',
      'search_terms']);

  }
}

The testGetIndex() method is OK the problem arises with the testGetSearch() method. What might cause the error?

HomeController code is as follows:

<?php namespace App\Http\Controllers;

use View;
use Input;
use Settings;
use DB;

use App\Brand;
use App\Category;
use App\Review;
use App\Product;
use App\Image;
use App\User;
use App\FeaturedReview;
use App\ReviewReportingReason;


class HomeController extends Controller
{

    public function getIndex() {


            $featured_reviews = FeaturedReview::OrderBy('id', 'DESC')->take(5)->get();

            $reviews = Review::where('active', '=', 1)->OrderBy('id', 'DESC')->take(5)->get();

            $featured_categories = Category::OrderBy('id', 'DESC')->where('featured', '=', 1)->get();

            $images = Image::OrderBy('id', 'DESC')->take(5)->get();


        if ($reviews) {

Answer 1

The problem was in the view file, where a file with a html source code for a modal window was included with @include('modal') instead of @yield('modal'). The file was not formated as a blade template, just plain html without blade directives.
