Laravel Dusk - Class config does not exist

Question

recently upgraded a 5.3 project to 5.4 and all seemed good.

Today I started to implement Dusk however had hit an issue when running the example test

☁  footy-finance [5.4] ⚡ php artisan dusk
PHPUnit 6.0.0 by Sebastian Bergmann and contributors.

E                                                                   1 / 1 (100%)

Time: 162 ms, Memory: 6.00MB

There was 1 error:

1) Tests\Browser\ExampleTest::testBasicExample
ReflectionException: Class config does not exist

/Users/owen/Sites/footy-finance/vendor/laravel/framework/src/Illuminate/Container/Container.php:681
/Users/owen/Sites/footy-finance/vendor/laravel/framework/src/Illuminate/Container/Container.php:565
/Users/owen/Sites/footy-finance/vendor/laravel/framework/src/Illuminate/Foundation/helpers.php:105
/Users/owen/Sites/footy-finance/vendor/laravel/framework/src/Illuminate/Foundation/helpers.php:263
/Users/owen/Sites/footy-finance/vendor/laravel/dusk/src/TestCase.php:203
/Users/owen/Sites/footy-finance/vendor/laravel/dusk/src/TestCase.php:40

I've had a look at line 40 of TestCase.php and its

public function baseUrl()
{
    return config('app.url');
}

So it does look like something to do with the global config helper anybody have any ideas?

I'm running

• PHP 7.0.14
• Laravel/Framework 5.4.8
• Laravel/Dusk 1.0.5

The full composer.lock can be seen https://gist.github.com/OwenMelbz/c05172b33f6eb4483e37a56469b53722

Fingers crossed you guys have some ideas!

Cheers :)

Answer 1

I had this error in the log

Class config does not exist

the problem with me was that in the .env file I had set a configuration variable in the following way:

APP_NAME=Application Name

note the space. When I changed it to this:

APP_NAME="Application Name" 

the problem got fixed

Answer 2

The issue is with .env file App_Name

in the original file its written this way>>> APP_NAME=Application Name

Make it like this APP_NAME="Application Name"

Answer 3

In my case, this solution works:

1) Remove all contents of the bootstrap/cache folder
2) Run the composer dump command

Answer 4

For anybody else who has had this issue.

I had prefer stable set in the composer file, which installed PHPUnit 6.

This was "made stable today" - thus it installed during a composer update.

Downgrading to PHPUnit 5 fixes the issue - so was bad timing starting it today.

Answer 5

I just ran into the the same issue, in my case the .env was all clean, no unwrapped empty spaces.

This error message can also occur when writting/debugging a test case, using the setup() method in that test, forgetting to call parent::setup() as the first statement in that function.

protected $stuf;

function setup() {
    parent::setup();

    $this->stuf = 'stuf';
}

I found very useful info here on what else could happen when you're getting this error message.

Answer 6

I had this in a Lumen application today. After some investigation and playing around, I found that it was because in PHPStorm it was adding the --no-configuration option onto the phpunit command because I hadn't configured my PHPUnit setup for the project in the IDE.

I corrected that by clicking 'Run > Edit Configurations' and then under 'Defaults > PHPUnit' click the little button to the far right of the 'Use alternative configuration file:' option and set the 'Default configuration file:' to the full path to your project's phpunit.xml.

Hope this helps!

Answer 7

I've also had this issue. For me it was caused by calling the config() function inside a dataProvider method. DataProviders are called before the createApplication() method initialises the application, and populates the DI container. Hence config() fails because the app('config') call in the helper function can't resolve the config class from the container.
