Try adding -devat the end of the branch you need:
composer require test/lib:master-dev
composer require test/lib:release-1.0.1-dev
If it says that it cannot find the specified package test/lib, then it is not on packagist.org (composer looks for packages there by default), therefore, you need to write the package address in composer.json:

"repositories": [
    {
      "type": "git",
      "url": "[email protected]:test/lib.git"
    },
 ]
