--TEST--

See GitHub issue #8902 ( https://github.com/composer/composer/issues/8902 ).

Avoid installing packages twice if they are required in different versions and one is matched by a dev package.

Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires beyondcode/laravel-dump-server ^1.3 -> satisfiable by beyondcode/laravel-dump-server[1.4.0].
    - Root composer.json requires laravel/framework ^6.8 -> satisfiable by laravel/framework[6.8.14].
    - beyondcode/laravel-dump-server 1.4.0 requires symfony/var-dumper ^5.0 -> satisfiable by symfony/var-dumper[5.2.x-dev (alias of dev-master)].
    - laravel/framework 6.8.14 requires symfony/var-dumper ^4.3.4 -> satisfiable by symfony/var-dumper[4.4.0].
    - You can only install one version of a package, so only one of these can be installed: symfony/var-dumper[dev-master, 4.4.0].
    - symfony/var-dumper 5.2.x-dev is an alias of symfony/var-dumper dev-master and thus requires it to be installed too.
