• Mockito

  11 14,568 9.0 Java

• Flyway

  80 7,763 7.2 Java

  Flyway by Redgate • Database Migrations Made Easy.

  

Project mention: Ask HN: What tool(s) do you use to code review and deploy SQL scripts? | news.ycombinator.com | 2024-04-14

Also RedGate, but Flyway has some reasons to recommend it over RedGate Deploy depending on your DBAs/workflows: https://flywaydb.org/

(Though I don't think it is "complete" or "perfect", either.)

EF Migrations are in a really good place now if you like/don't mind C# as a language (and you can easily embed SQL inside the C#, too, but there are benefits to being able to also run high level C# code). With today's tooling you can package your migration "runner application" as a single deployable executable for most platforms. You can build the executable once and run it in all your environments. (The same tool that updates your QA and Staging updates your Prod, testably running the same migrations.) Given the single executable deployable I might even consider using it for projects not themselves written in C#.

• InfluxDB

• Byte Buddy

  5 6,006 9.0 Java

  Runtime code generation for the Java virtual machine.

Project mention: Monkey-patching in Java | dev.to | 2023-09-21

As seen above, the API exposes the user to low-level bytecode manipulation via byte arrays. It would be unwieldy to do it directly. Hence, real-life projects rely on bytecode manipulation libraries. ASM has been the traditional library for this, but it seems that Byte Buddy has superseded it. Note that Byte Buddy uses ASM but provides a higher-level abstraction.
