From 86e8afb98032e909ef65c9402a1b1a9c442e0204 Mon Sep 17 00:00:00 2001 From: Holly Cummins Date: Thu, 30 May 2024 17:58:04 +0100 Subject: [PATCH] Revert "Revert #40601 and disable tests enabled by #40749" This reverts commit fc3988b0e246095f3c6a09e4b750dbe4b09eeae6. It has some additional changes which re-revert part of #40601, to reintroduce removed guards to avoid cloning things like Quarkus runtime classes. Otherwise we get test failures. --- bom/application/pom.xml | 5 + .../extension/it/TestParameterDevModeIT.java | 2 - test-framework/junit5/pom.xml | 6 +- .../test/junit/QuarkusTestExtension.java | 6 +- .../junit/internal/CustomListConverter.java | 63 ---------- .../junit/internal/CustomMapConverter.java | 41 ------- .../internal/CustomMapEntryConverter.java | 55 --------- .../junit/internal/CustomSetConverter.java | 40 ------- .../internal/NewSerializingDeepClone.java | 113 ++++++++++++++++++ .../internal/SerializationDeepClone.java | 46 ------- ...alizationWithXStreamFallbackDeepClone.java | 35 ------ .../junit/{ => internal}/TestInfoImpl.java | 6 +- .../test/junit/internal/XStreamDeepClone.java | 61 ---------- 13 files changed, 127 insertions(+), 352 deletions(-) delete mode 100644 test-framework/junit5/src/main/java/io/quarkus/test/junit/internal/CustomListConverter.java delete mode 100644 test-framework/junit5/src/main/java/io/quarkus/test/junit/internal/CustomMapConverter.java delete mode 100644 test-framework/junit5/src/main/java/io/quarkus/test/junit/internal/CustomMapEntryConverter.java delete mode 100644 test-framework/junit5/src/main/java/io/quarkus/test/junit/internal/CustomSetConverter.java create mode 100644 test-framework/junit5/src/main/java/io/quarkus/test/junit/internal/NewSerializingDeepClone.java delete mode 100644 test-framework/junit5/src/main/java/io/quarkus/test/junit/internal/SerializationDeepClone.java delete mode 100644 test-framework/junit5/src/main/java/io/quarkus/test/junit/internal/SerializationWithXStreamFallbackDeepClone.java rename test-framework/junit5/src/main/java/io/quarkus/test/junit/{ => internal}/TestInfoImpl.java (79%) delete mode 100644 test-framework/junit5/src/main/java/io/quarkus/test/junit/internal/XStreamDeepClone.java diff --git a/bom/application/pom.xml b/bom/application/pom.xml index 82635f6f91c337..764d26301515be 100644 --- a/bom/application/pom.xml +++ b/bom/application/pom.xml @@ -4848,6 +4848,11 @@ pom + + org.jboss.marshalling + jboss-marshalling + ${jboss-marshalling.version} + org.jboss.threads jboss-threads diff --git a/integration-tests/test-extension/tests/src/test/java/io/quarkus/it/extension/it/TestParameterDevModeIT.java b/integration-tests/test-extension/tests/src/test/java/io/quarkus/it/extension/it/TestParameterDevModeIT.java index 6219d4c8ca510d..83355e35ca9469 100644 --- a/integration-tests/test-extension/tests/src/test/java/io/quarkus/it/extension/it/TestParameterDevModeIT.java +++ b/integration-tests/test-extension/tests/src/test/java/io/quarkus/it/extension/it/TestParameterDevModeIT.java @@ -7,7 +7,6 @@ import org.apache.maven.shared.invoker.MavenInvocationException;
