? static?

The main issue is with BasePersistenceFactory. Because it is annotated with @configuration, it gets initialised before we can create a temporary folder and set it as the source for BasePersistenceFactory.

The only reliable way we found to inject a temporary directory is via @DynamicPropertySource. However, this method requires the property to be static. As a result, the temporary directory also has to be static, which is counterintuitive when we want isolated temporary folders for each test.

One workaround is to set a static temporary folder as the initial source so that BasePersistenceFactory does not attempt to create its own directories, and then override this value in @beforeeach with a new temporary folder. This approach works, but in some tests it leads to desynchronization between the current working directory and the one registered earlier. While this can be solved by adjusting the affected tests, it makes the setup less intuitive and harder to maintain.

Overall, I have this solution coded and can push it, but I'm not sure if it would be worth it.

Do we really need this ?

Do we need to extend every test with this ?

In short, here’s the solution:

• Added two new config classes: RepositoryPathConfig and ScriptPathConfig.
• They manage the parameters: scriptPath, rdf4j.RepositoryUrl, and rdf4j.RepositoryName.
• In production, these values are still read from application.properties (no change in behaviour), but are now exposed as Beans.
• In the test environment, they create temporary folders, handle their cleanup, and expose them as Beans.
• The rest of the code now consumes the injected beans (scriptPath, rdf4jRepositoryUrl, rdf4jRepositoryName) instead of reading application properties directly.

This cleanly separates repository handling logic between prod and test, while keeping the overall design consistent and minimally changed.

Additionally:

• We no longer need @DirtiesContext in tests.
• Tests won’t fail due to leftover directories being reused as repositories.
