Vue Test Utils Compatibility Layer

vue-test-utils-compat provides a critical compatibility layer for migrating existing Vue 2 test suites written with `@vue/test-utils` v1 to run seamlessly on `@vue/test-utils` v2 and Vue 3. This package, currently at version 0.0.15, is designed to ease the transition burden by allowing developers to upgrade their Vue components to Vue 3 first, and then address test migrations, leveraging Vue 3's migration build. It achieves this by providing numerous compatibility flags that can be configured to mimic v1 behavior, addressing differences in mounting options, wrapper APIs, and event handling. Its release cadence is tied to the needs of the Vue 2 to Vue 3 migration process. A key differentiator is its extensive configuration options, allowing granular control over which v1 behaviors are re-enabled, facilitating a gradual and less disruptive migration path.
