noxid-cli 0.2.0

//! Give a scaffolded temp project the vetted database driver it now owns.
//!
//! `2cd38b2` ("Resolve database drivers from projects") removed the migration
//! runner's fallback to the compiler installation's own `node_modules`, and
//! `d27d3e7` ("Resolve hoisted migration drivers") settled the replacement on
//! plain Node resolution rooted at the project manifest, so a workspace-hoisted
//! install still resolves. A fixture created under the system temp directory
//! has no `node_modules` in any ancestor, so `noxid db migrate` now refuses
//! with `DATABASE_DRIVER_MISSING` before it can reach the behaviour under test.
//!
//! Linking the repository's installed dependencies into the fixture root is the
//! pattern the same commit introduced for `wo37_mysql.rs`
//! (`install_repository_dependencies`); this is that helper, shared by every
//! fixture that drives a live database.
