Laravel 9.x - Feature and Unit Test

Question

I have two test classes Tests\Unit\BlogTest and Tests\Feature\BlogTest. In Tests\Unit\BlogTest, the response should be 422, which is obviously not good for redirection.

Below is BlogController -> Create() method code:

if ($validator->fails()) {
  if (app()->runningUnitTests()) {
    return response('Validation failed', 422);
  }
  return redirect()->route('blog_edit', ['id' => $id])
    ->withErrors($validator)
    ->withInput();
}

Below code is from Tests\Unit\BlogTest

public function test_blog_create_validation()
{
    $reqData = ['title' => null, 'author' => null, 'content' => null];
    $response = $this->postJson(
        action([BlogController::class, 'create']),
        $reqData
    )->assertStatus(422);
}

Below code is from Tests\Feature\BlogTest

public function test_blog_create_validation()
{
    $response = $this->post('/blog', [
        'title'   => '',
        'author'  => '',
        'content' => ''
    ]);
    
    $response->assertSessionHasErrors([
        'title',
        'author',
        'content'
    ]);
}

Now, the problem is, app()->runningUnitTests()) condition satisfy unit test, without this condition, it satisfy feature test. See below images for the reference:

1. Feature test passed without condition, but unit test failed
2. Unit test passed with condition but feature test failed

Question: How to satisfy both Unit and Feature tests?
