Trouble running integration tests - help?

[forsberg]

Hi!

Being a now-and-then Java coder, I'm having some trouble trying to run the integration tests.

I'm trying to run the smoke integration tests as described in https://github.com/Apicurio/apicurio-registry/blob/main/TESTING.md#integration-tests, as follows:

1. In my apicurio-registry clone, I run ./mvnw clean install -DskipTests which succeeds.
2. Changing directory into the integration-tests directory, I run ../mvnw verify -Plocal-mem -Psmoke

The latter however fails with:

This is on Linux, with:

java -version
openjdk version "18.0.2-ea" 2022-07-19
OpenJDK Runtime Environment (build 18.0.2-ea+9-Ubuntu-222.04)
OpenJDK 64-Bit Server VM (build 18.0.2-ea+9-Ubuntu-222.04, mixed mode, sharing)

What am I doing wrong?

Hey @forsberg, sorry, this is happening due to bad instructions on our side. That is likely happening because you have two flavours of the applications in your integration-tests classpath. I recommend running the tests with ../mvnw clean verify -Plocal-mem -Psmoke letting maven to pick which one of the flavours of the application should be used (in the case of this command, the in-memory version of the application). We're working on both improving the instructions on how to run the tests and also on making it actually simpler.
