Php Laravel 5.6：AssertSessionHas错误导致；完整性约束冲突：19非空约束失败“；错误

我正在尝试设置一个测试，检查不完整的表单是否无法提交到数据库，并且我不断遇到问题，目前每次运行phpunit时，我都会得到以下结果：

我的测试设置如下：

public function test_incomplete_form_cannot_be_submitted()
{
  $user = factory(User::class)->states('confirmed', 'normaluser')->create([
      'id' => '1',
  ]);
  $form = factory(Form::class)->states('incomplete')->create(['status' => 'submitted', 'user_id' => '1', 'id' => '5',]);

  $this->actingAs($user)->post(route('forms.store'), $form->toArray());

  $this->assertSessionHasErrors(['company_name', 'form_info', 'uploads', 'state']);
}

设置不完整表格的工厂设置如下：

 $factory->state(App\Form::class, 'incomplete', function (Faker $faker) {
  return [
    'company_name' => null,
    'form_info' => [
      'contact_fname' => null,

我已经尝试将测试从factory…->create更改为factory…->make，修改assertSessionHasErrors以只检查['uploads.top_25_accounts'，并使$form只是一个空数组，但似乎没有任何效果

问题1:

public function test_incomplete_form_cannot_be_submitted()
{
  $user = factory(User::class)->states('confirmed', 'normaluser')->create([
      'id' => '1',
  ]);
  $form = factory(Form::class)->states('incomplete')->make([
      'status' => 'submitted', 
      'user_id' => '1', 
      'id' => '5',
  ]);

  $response = $this->actingAs($user)->post(route('forms.store'), $form->toArray());

  $response->assertSessionHasErrors(['company_name', 'form_info', 'uploads', 'state']);
}

由于工厂中的

create（）

试图在数据库中创建一个新条目，但

company\u name

不能为

NULL

，因此无法到达您的断言，并引发异常

解决方案：

public function test_incomplete_form_cannot_be_submitted()
{
  $user = factory(User::class)->states('confirmed', 'normaluser')->create([
      'id' => '1',
  ]);
  $form = factory(Form::class)->states('incomplete')->make([
      'status' => 'submitted', 
      'user_id' => '1', 
      'id' => '5',
  ]);

  $response = $this->actingAs($user)->post(route('forms.store'), $form->toArray());

  $response->assertSessionHasErrors(['company_name', 'form_info', 'uploads', 'state']);
}

将

create（）

更改为

make（）

问题2:

public function test_incomplete_form_cannot_be_submitted()
{
  $user = factory(User::class)->states('confirmed', 'normaluser')->create([
      'id' => '1',
  ]);
  $form = factory(Form::class)->states('incomplete')->make([
      'status' => 'submitted', 
      'user_id' => '1', 
      'id' => '5',
  ]);

  $response = $this->actingAs($user)->post(route('forms.store'), $form->toArray());

  $response->assertSessionHasErrors(['company_name', 'form_info', 'uploads', 'state']);
}

您必须对响应对象调用

assertSessionHasErrors（）

<代码>$this->assertSessionHasErrors）不存在

解决方案：

public function test_incomplete_form_cannot_be_submitted()
{
  $user = factory(User::class)->states('confirmed', 'normaluser')->create([
      'id' => '1',
  ]);
  $form = factory(Form::class)->states('incomplete')->make([
      'status' => 'submitted', 
      'user_id' => '1', 
      'id' => '5',
  ]);

  $response = $this->actingAs($user)->post(route('forms.store'), $form->toArray());

  $response->assertSessionHasErrors(['company_name', 'form_info', 'uploads', 'state']);
}

您是否在

工厂（表单：：类）->states（'completed'）->make（…）

中收到相同的错误？看起来工厂正试图在数据库中创建一个新条目，但是

company\u name

不能为NULL并引发异常，因此您的断言永远不会到达。奇怪的是，现在测试只会给我一条错误消息“error:Call to undefined method Tests\Feature\FormTest:：assertSessionHasErrors（）”我必须指定上传部分（uploads.top_25_accounts），但除此之外，这也成功了，谢谢！
