/**
 * Tests for GitHub issue #7802: volume mappings from repo content in Preview Deployments.
 *
 * Behavioral tests for addPreviewDeploymentSuffix and related helper functions.
 *
 * Note: The parser functions (applicationParser, serviceParser) and
 * ApplicationDeploymentJob methods require database-persisted models with
 * relationships (Application->destination->server, etc.), making them
 * unsuitable for unit tests. Integration tests for those paths belong
 * in tests/Feature/.
