Phpunit 在 laravel5.1 上重定向时失败

当我运行phpunit时，即使我在实际浏览器上进行了测试，它也失败了。

我期望的是当用户注册治疗师时，输入所需的信息并按下按钮，然后转到下一个屏幕以将他/她分配到分支。

谁能解释一下出了什么问题？

phpunit的堆栈跟踪如下：

测试是这样的：

12    public function testCreate()
13    {
14      $user = self::getOwner();
15      $this->assertNotNull($user);
16      $this->actingAs($user)
17              ->visit('/therapists/register')
18              ->see('Register New Therapist')
19              ->type('Test Therapist 4', 'name')
20              ->select('false', 'lmt')
21              ->press('Register')
22              ->seePage('New therapist was registered. Please assign the branches that he / she belongs to.')
23              ->seePage('Assign Branches to Therapist')
24              ;
25    }

刀片代码是这样的：

@section('content')
          @include('common.message')
          <h1>Register New Therapist</h1>
          {!! Form::open(array('action' => ['TherapistsController@doRegister'])) !!}
          @include('therapists.form', ['modifier' => 'required'])
            <div style="text-align:right;">
              {!! Form::submit('Register', ['class' => 'submit btn btn-primary btn-lg']) !!}
            </div>
          {!! Form::close() !!}
@endsection

那么控制器的代码是这样的：

  public function doRegister(Request $request)
  {
    $therapist = self::createData($request);
    'Session::flash('flash_success', 'New therapist was registered. Please assign the branches that he / she belongs to.');
    return redirect()->route('therapists.preAssign', $therapist->therapist_id);
  }

我也有类似的代码，但它通过没有任何错误。

测试代码如下：

  public function testCreate()
  {
    $user = self::getAccountant();
    $this->assertNotNull($user);
    $this->actingAs($user)
            ->visit('/categories/create')
            ->see('Add New Expense Category')
            ->type(self::CATEGORY_NAME, 'name')
            ->press('Add')
            ->see('View Existing Expense Category')
            ->see('New category was registered.')
            ->see(self::CATEGORY_NAME)
            ;
  }

刀片如下：

@section('content')
          @include('common.message')
          <h1>Add New Expense Category</h1>
          {!! Form::open(array('action' => ['CategoriesController@doCreate'])) !!}
            @include('categories.form', ['modifier' => 'required'])
            <div style="text-align:right;">
              {!! Form::submit('Add', ['class' => 'submit btn btn-primary btn-lg']) !!}
            </div>
          {!! Form::close() !!}
@endsection

控制器如下：

  public function doCreate(Request $request)
  {
    $name = $request->name;
    $category = Category::create(['name' => $name]);
    $item = Item::create(['name' => $name]);
    CategoryItem::create(["category_id" => $category->category_id, "item_id" => $item->item_id]);
    'Session::flash('flash_success', 'New category was registered. As default, the same item is also registered under the category.');
    return redirect()->route('categories.show', [$category]);    
  }

我提前感谢您的支持。
