Pact JVM VS Spring Boot

API Contract Testing might be worth exploring. Gives you the ability to run it quickly locally or in CI/CD. A centralized way to validate if your changes broke another service might also be interesting. That series of videos from the same team is gold: https://docs.pact.io

We use Pact for contract testing https://docs.pact.io/

The introduction here is quite good: https://docs.pact.io/

Pact.Net documentation: https://docs.pact.io/ Mountebank documentation: http://www.mbtest.org/ The Microsoft.AspNetCore.TestHost package on GitHub: https://github.com/aspnet/AspNetCore/tree/main/src/Testing/Microsoft.AspNetCore.TestHost

There's also https://docs.pact.io/ but I haven't had time yet to really look into it but probably someone else can tell something about it.

This PoC shows a step by step implementation of contract testing using Pact.

Contract tests assert that inter-application messages conform to a shared understanding documented in a contract. Without contract testing, the only way to ensure that applications will work correctly together is by using expensive and brittle integration tests.

If you are updating your API based on user feedback, you can work with your team or stakeholders to build an API contract describing how your API should function. You can use JSON schemas to document your API’s endpoint response codes and set up the contract. The contract must be accepted by all parties. Then, any changes made to the API must pass the contract test before being approved. Contract testing can be automated and incorporated into your CI/CD pipeline. Contract testing tools include Pact and Spring Cloud Contract.

Pact.

I have contract tests (https://docs.pact.io/) to ensure the integration works.

- Usually manually wired and configured vs the spring boot "starter" pattern of having libraries that automatically do some of the manual setup work for you: https://github.com/spring-projects/spring-boot/blob/main/spr...

I wish more client library sets had the feature-matrix that the pulsar one does, because in practice most end up being the same: Java supports everything because it's either built in the same codebase or is the most used client and gets the most support, while the dotnet client codebase has many feature-requests or performance improvement issues, often leading to a "third-party client" being created.

If you’re currently running with an earlier version of Spring Boot, I recommend that you upgrade to Spring Boot 2.7 before migrating to Spring Boot 3.0. It minimizes compatibility issues as much as possible.

Okay, we need to build the game? No problem, we will use Spring Boot and Swing!

It's weird that some people including you directly attack my competence. As a power user you should have plenty of experience getting something to work that is not properly document, does not work how the documentation promised it to, or has weird problems on top of it. Look at idiotic things like this:

https://github.com/spring-projects/spring-boot/issues/33044

Take any similar issue and you'll see a bunch of people who try to find a solution for them because they just aren't repeatable at all. The underlying issue is the auto configuration doing things you can't follow quite properly. It's like it wasn't mean to be understood. Issues like the one I linked above also show me that the spring dev crowd also doesn't understand the ecosystem anymore. The problem is complexity and automagic.

Explicitly decoding URL query parameters occurs less often because many frameworks, including Spring Boot, handle decoding automatically.
