    Next-generation ORM for Node.js & TypeScript | PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, MongoDB and CockroachDB

  • I know I've seen other uses in Jenkins and I thought there was an SBT plugin, but my searching isn't turning up much. However, you can always do this with a little GHA customization: https://github.com/prisma/prisma/pull/6612

  • sbt-mima-plugin

    A tool for catching binary incompatibility in Scala

  • Off the top of my head, a naive & approximate solution would be to use test coverage to find out which tests test which blocks of code. Then, when a binary, syntactic incompatibility is detected, re-run only these tests captured for that piece of code.

  • SurveyJS
