I want to seed database when I use this

 public function run()
{
    $users = factory(app\User::class, 3)->create();
}

Add three user in database but when I use this

 public function run()
{
    $Comment= factory(app\Comment::class, 3)->create();
}

Show me error

[InvalidArgumentException] Unable to locate factory with name [default] [app\Comment].

By default the laravel installation comes with this code in the database/factories/ModelFactory.php File.

$factory->define(App\User::class, function (Faker\Generator $faker) {
    return [
        'name' => $faker->name,
        'email' => $faker->email,
        'password' => bcrypt(str_random(10)),
        'remember_token' => str_random(10),
    ];
});

So you need to define a factory Model before you use it to seed database. This just uses an instance of Faker Library which is used to generate fake Data for seeding the database to perform testing.

Make sure You have added a similar Modal Factory for the Comments Model.

So your Comments Model Factory will be something like this :

$factory->define(App\Comment::class, function (Faker\Generator $faker) {
    return [
        'comment' => $faker->sentence,
         // Any other Fields in your Comments Model 
    ];
});

Unable to locate factory with name [default]??, Unable to locate factory with name [default]?? The issue is that the documentation @ https://laravel.com/docs/5.4/database-testing#using-factories is that it is missing the slash. Posted 9 months ago by pSebstead (level 5). (InvalidArgumentException : Unable to locate factory with name [default] [App\Http\Models\Stock].) As I defined an App\Http\Models\Stock model and it's working properly, But not working in factory method. Steps To Reproduce: Create new laravel project. Create Model base on the given namespace; Then Try to use factory method

If nothing helps with PHPUnit.

For those of readers who stuck with the same issue in tests, I found out that I forgot to add parent::setUp() in setUp method.

Unable to locate factory with name [default] · Issue #28378 · laravel , Laravel Version: 5.8.* PHP Version: 7.2.5 Database Driver & Version: sqlite Description: public function testCreateRecord() { // case 1: $factory  InvalidArgumentException: Unable to locate factory with name [default] [App\User]. is because your app were unable to locate the User model. If you call it make sure you do: factory(\App\User::class)->create(); I ran into this problem when I'm doing my unit testing. I hope it helps.

Some times it could be due to importing the wrong TestCase

use PHPUnit\Framework\TestCase; [WRONG: and throws this error]


use Tests\TestCase; [CORRECT]

This can also happen when you are running the command factory()->create() from php artisan tinker. Make sure you save the file database/factories/ModelFactory.php before opening tinker

Laravel Factory. InvalidArgumentException with message 'Unable to , InvalidArgumentException with message 'Unable to locate factory with name [​default] [App\Contrato].' This could be a cache problem. You can resolve it executing  Hi all, Going through the testing laravel series, but I'm having trouble running my factory. I get the error: 1) Tests\Feature\BookingTest::testUserRelation InvalidArgumentException: Unable to locate factory with name [default] [App\User].

I'm using laravel 5.5 and for that doing this is bit different. You have to create CommentFactory.php inside \database\factories directory and add this inside,

$factory->define(App\Comment::class, function (Faker\Generator $faker) {
    return [
        'comment' => $faker->sentence,
         // Any other Fields in your Comments Model 
    ];
});

And add this,

$Comment= factory(\App\Comment::class, 3)->create();

instead of

$Comment= factory(app\Comment::class, 3)->create();

I just wanted to add this since I'm facing the same issue for later version and this thread helped me a lot to fix it.

Comments
  • Are the names and namespaces correct? Do classes really exist?
  • Shouldn't that be App rather than app? Also, the error message says Commnet so if you really copy-pasted the above code then the error comes from somewhere else.
  • I'm sorry. I copy wrong. I edit my post
  • Have you defined the model factory?
  • My problem was that I'd been using App\Contact instead of \App\Models\Contact (notice that I needed a slash at the beginning and also \Models).
  • And when you take a look at line 129 in github.com/illuminate/database/blob/master/Eloquent/… you'll see why @Angry Coder is right. At the moment there's no definition for your Comment class.
  • Thanks for pointing that out, I was looking in all the wrong places.
  • Probably saved me an entire day of pulling my hair out, considering everything else was right.
  • Solved my problem. I thought it's not necessary to have the call to the parent class, but apparently it's required!
  • After I defined a __construct method in my local TestCase class which all my tests extend, I had to run parent::setUp() to it in order to not override the default behaviour.
