Have you set up the provider and alias in config/app.php? Judging from the facade root has not been set message that is where I would start looking.

How can I test a custom package that use Facades?
If I have this example class in my package:
<?php
namespace Foo\Bar;
use Illuminate\Support\Facades\DB;
class Example
{
protected $model;
public function __construct($model)
{
$this->model = $model;
}
public function execute()
{
$dummyData = collect([
['foo' => 'bar'],
['foo' => 'baz'],
]);
foreach ($dummyData->chunk(100) as $chunk) {
DB::transaction(function () use ($chunk) {
$this->model->insert($chunk->toArray());
});
}
}
}
And this TestExemple.php
<?php
use Foo\Bar\Example;
class TestExemple extends TestCase
{
/** @test */
function it_should_load_data()
{
$model = $this->getModel(); // TestCase class
$example = new Example($model);
$example->execute();
$this->assertEquals(2, $model->all()->count());
}
}
When i run phpunit i get:
1) TestExemple::it_should_load_data
RuntimeException: A facade root has not been set.
/path/to/package/vendor/illuminate/support/Facades/Facade.php:210
/path/to/package/src/Example.php:24
How can I make the Facade work without a full Laravel installation?

I don't have the config/app.php file, its a custom package and I'm trying to write tests using only the dependencies I need without a full Laravel installation.
Ah, well I've never seen that error message before but a quick search produces this stack question. Maybe it will help.

I saw that post, but according to the laravel docs: https://laravel.com/docs/5.2/facades that is not the same class as the facade. And I will need to use some others facades like Config
I'm unsure. But it does appear that the piece that is failing is:
DB::transaction(function () use ($chunk) {
$this->model->insert($chunk->toArray());
This is probably because Illuminate\Support\Facades\DB returns the string 'db'. So you'll have to connect that string to registering an instance of the database class through the Illuminate\Database\DatabaseServiceProvider. I think you're going to have to make your own equivalent of a config/app.php along with a way to call it, like how Laravel does when it boots.
Alternatively, the github issue linked to by the question talks about creating a new app container to use the facade with the context of using standalone Eloquent. This seems like it's what you want. Have you tried that?

Just tried it, getting a different error now:

Hey @dev@menudrive.com, I was in a rush, saw a different error and thought it was an assertion error. But actually, after i tried:
$app = new Container();
$app->singleton('app', 'Illuminate\Container\Container');
Facade::setFacadeApplication($app);
$app->bind('db', 'Illuminate\Database\DatabaseManager');
I'm getting this error:
1) ExampleTest::it_should_load_data
Illuminate\Contracts\Container\BindingResolutionException: Unresolvable dependency resolving [Parameter #0 [ <required> $app ]] in class Illuminate\Database\DatabaseManager
@leomarquine Awesome! Glad you got it working.

Working code on the setUp method in my test:
$app = new Container();
$app->singleton('app', 'Illuminate\Container\Container');
$app->singleton('config', 'Illuminate\Config\Repository');
$app['config']->set('database.default', 'test');
$app['config']->set('database.connections.test', [
'driver' => 'sqlite',
'database' => ':memory:',
]);
$app->bind('db', function ($app) {
return new DatabaseManager($app, new ConnectionFactory($app));
});

Was looking up this issue myself and thought I'd share my experience.
I was about to add the Container and bind as in the example above when I realized that the test that I'm working on is calling DB from __construct(). Before trying the code above, I switched the method from __construct() to setUp(), calling parent::setUp() as the first line. Executed fine. No more root error.

Hello.
I have the same problem with Config.
I can't find what to put in setUp in order to not have the "A facade root has not been set." error.
Do you solve this ?
Thank you.

Have you seen https://github.com/orchestral/testbench? Might be worth checking out.

Config works, logging (via Log::debug( ) ) doesn't. Hmm... running into the same sort of issue with a custom package that I want to unit test certain log writing features of the package.
