Testing Database using laravel dusk

Question

I am testing my laravel application using laravel dusk but the problem is that I am unable to use assertDatabaseHasfunction. When I run php artisan dusk command I got this error:

PHP Fatal error:  Class 'PHPUnit_Framework_Constraint' not found in 
vendor\laravel\framework\src\Illuminate\Foundation\Testing\Constraints\HasIn
Database.php on line 8

Here is my code:

$this->assertDatabaseHas('teams', [
    'name' => $data['team_name'],
]);

Please check your version of phpunit:

phpunit --version

If you are are running v6 you might have trouble because it expects a namespaced class. In that case you either have to switch to an older version of phpunit, e.g. locally installed for your project and then run like this:

php vendor/bin/phpunit --version

or you might have to update your Laravel-project, which is probably more work as you might have to change parts of your code.

Thanks, Problem solved after switching to PHPUnit 5.7 version. :)

@ZeeshanAhmed you should stay on 6.1 and use PHPUnit\Framework\Constraint instead. Then just extend Constraint

@MarcoAurélioDeleu well it's a class from Laravel framework. Changing code there is not a good idea, as you usually don't want to maintain your own fork. The better option would be an upgrade as I mentioned above, but unfortunately Laravel has breaking changes in minor versions, making it non-trivial for some existing projects to switch to a newer version.
