makeVendorPackage example

// Disable packagist globally (but only in our own custom COMPOSER_HOME).     // It is necessary to do this globally rather than in our SUT composer.json     // in order to ensure that Packagist is disabled during the     // `composer create-project` command.     $this->executeCommand("COMPOSER_HOME=$composer_home composer config --no-interaction --global repo.packagist false");

    // Tests are typically run on "-dev" versions, but we want to simulate     // running them on a tagged release at the same stability as specified in     // static::MINIMUM_STABILITY, in order to verify that everything will work     // if/when we make such a release.     $simulated_core_version = \Drupal::VERSION;
