We now provide a ScenarioCustomizer that can be used to prepare Scenario instances for test methods with a common customizer. This avoids the need to call ….customize(…) for all Scenarios declared in a test class with the same logic.
Renamed top-level section to "Production-ready features" to align with Spring Boot. Moved actuator support before observability one. Introduced introductory section to showcase the Insight starter.
To make sure that we trigger transactional event listeners from Scenario based integration tests, we trigger stimulus executions using transactions configured to require a new transaction. This makes sure that Scenarios work in integration tests using @Transactional, of course circumventing the default rollback behavior of those transactions. There's no other way to implement this as we *need* to commit a transaction to trigger the delivery of transaction-bound events.
Fixed a bug in the handling of Scenario.stimulus(Supplier<T>) as for this, the Supplier handed into the method had not been executed transactionally at all.
Introduce Spring Modulith Actuator module to expose the application module structure as Spring Boot actuator. This required a Spring Modulith Runtime module to be extracted from the Spring Modulith Observability one. The former now contains the auto-configured ApplicationRuntime and ApplicationModulesRuntime bean instances to be able to bootstrap a ApplicationModules asynchronously on application startup. The actuator module then contains a Spring Boot @Endpoint implementation consuming the ApplicationModules to render JSON describing the application module structure.
We now provide @ApplicationModuleIntegrationListener as shortcut for the combination of @Async @Transactional @TransactionalEventListener to provide a dedicated annotation for the recommended integration arrangement.
