Laravel 5.1 PhpUnit action more than once does not work

Here is my Code.

   <?php

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

   use App\Models\master\Company;
   use App\User;

   class JobReferenceControllerTest extends TestCase
   {


    public function setUp(){
      parent::setUp();
      // $this->mock = \Mockery::mock('Moloquent','App\Models\master\Company');
      $company                =     new Company;
      $company->cmp_name          =  'TestCompany123';
      $company->cmp_website          =  'www.testcompany.com';
      $company->cmp_desc          = 'This is Description';
      $company->cmp_employe          =  '0-100';
      $company->save();
    }

    public function testAddJobWithoutTitleFunctionality(){
        $company    =     Company::where('cmp_name','=','TestCompany123')->orderBy('created_at','desc')->first();
        $status   =   true;
        if($company == null){
          $status  =   false;
        }

        $this->assertEquals($status,true);

        $parameters   =   [
            'job_description' => 'Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

            'job_type' => 'WALKIN',
            'job_valid_to' => '2016-07-07',
            'for_company_id' => $company->_id
        ];
        $cookies  =   [];
        $files  =   [];

        $user = User::where('email','=','lokesh@skoolkhojo.com')->first();
        if($user != null){
          $this->be($user);
        }

        $response = $this->action('POST', '\App\Http\Controllers\Api\Features\JobReferenceController@store', $parameters);


        // var_dump($response->getContent());
        $this->assertEquals(400, $response->getStatusCode());

    }

    public function testAddJobFunctionality(){
         $this->withoutMiddleware();

        $company    =     Company::where('cmp_name','=','TestCompany123')->orderBy('created_at','desc')->first();
        $status   =   true;
        if($company == null){
          $status  =   false;
        }

        $this->assertEquals($status,true);
        $parameters   =   [
            'job_title' => 'Dummy Job',
            'job_description' => 'Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

            'job_type' => 'WALKIN',
            'job_valid_to' => '2016-07-07',
            'for_company_id' => $company->_id
        ];


        $user = User::where('email','=','lokesh@skoolkhojo.com')->first();
        if($user != null){
          $this->be($user);
        }

        $action   =   '\App\Http\Controllers\Api\Features\JobReferenceController@store';
        $response = $this->action('POST',$action, $parameters);
        $this->assertEquals(200, $response->getStatusCode());

    }


    public function tearDown(){
      $company    =     Company::where('cmp_name','=','TestCompany123')->orderBy('created_at','desc')->first();
      if($company != null){
        $company->delete();
      }
      parent::tearDown();
    }

}

It execute the statement for first time 
$response = $this->action('POST',$action, $parameters);

Latter says 

1) JobReferenceControllerTest::testAddJobFunctionality InvalidArgumentException: Action App\Http\Controllers\Api\Features\JobReferenceController@store not defined.

/Users/lokesh/Documents/projects/skoolkhojo_v2/skoolkhojo_services/vendor/laravel/framework/src/Illuminate/Routing/UrlGenerator.php:590 /Users/lokesh/Documents/projects/skoolkhojo_v2/skoolkhojo_services/vendor/laravel/framework/src/Illuminate/Foundation/Testing/CrawlerTrait.php:435 /Users/lokesh/Documents/projects/skoolkhojo_v2/skoolkhojo_services/tests/Http/Controllers/Api/Features/JobReferenceControllerTest.php:81
