From 426ae19039db69e0cc5cc6613e83ca6479fdffa6 Mon Sep 17 00:00:00 2001 From: jomin mathew <> Date: Tue, 24 Mar 2026 12:10:55 +0000 Subject: [PATCH 1/3] Fixes #6195: Add integration tests for Saga example Created saga-integration-tests module with comprehensive test coverage for the Saga/LRA example demonstrating distributed transaction coordination using Testcontainers. Changes: - New saga-integration-tests module with 4 integration tests - Tests verify LRA coordination, JMS messaging, and service participation - Testcontainers manages Artemis broker and LRA coordinator lifecycle - Improved container wait strategies (HTTP health check vs log matching) - Added JMS request-timeout configuration (5s) to prevent test timeouts - Updated main README.adoc with testing documentation - Comprehensive README.md in saga-integration-tests module --- saga/README.adoc | 16 +++ saga/pom.xml | 1 + saga/saga-integration-tests/README.md | 121 ++++++++++++++++ saga/saga-integration-tests/pom.xml | 134 ++++++++++++++++++ .../camel/example/saga/FlightRoute.java | 41 ++++++ .../camel/example/saga/PaymentRoute.java | 42 ++++++ .../apache/camel/example/saga/SagaRoute.java | 51 +++++++ .../apache/camel/example/saga/TrainRoute.java | 41 ++++++ .../src/main/resources/application.yml | 48 +++++++ .../camel/example/saga/SagaBasicIT.java | 28 ++++ .../camel/example/saga/SagaBasicTest.java | 116 +++++++++++++++ .../camel/example/saga/SagaTestResource.java | 106 ++++++++++++++ .../src/test/resources/application.yml | 56 ++++++++ 13 files changed, 801 insertions(+) create mode 100644 saga/saga-integration-tests/README.md create mode 100644 saga/saga-integration-tests/pom.xml create mode 100644 saga/saga-integration-tests/src/main/java/org/apache/camel/example/saga/FlightRoute.java create mode 100644 saga/saga-integration-tests/src/main/java/org/apache/camel/example/saga/PaymentRoute.java create mode 100644 saga/saga-integration-tests/src/main/java/org/apache/camel/example/saga/SagaRoute.java create mode 100644 saga/saga-integration-tests/src/main/java/org/apache/camel/example/saga/TrainRoute.java create mode 100644 saga/saga-integration-tests/src/main/resources/application.yml create mode 100644 saga/saga-integration-tests/src/test/java/org/apache/camel/example/saga/SagaBasicIT.java create mode 100644 saga/saga-integration-tests/src/test/java/org/apache/camel/example/saga/SagaBasicTest.java create mode 100644 saga/saga-integration-tests/src/test/java/org/apache/camel/example/saga/SagaTestResource.java create mode 100644 saga/saga-integration-tests/src/test/resources/application.yml diff --git a/saga/README.adoc b/saga/README.adoc index 950c235b..4b0babc4 100644 --- a/saga/README.adoc +++ b/saga/README.adoc @@ -14,6 +14,7 @@ There are 4 services as participants of the Saga: -
