From 34922e2fdb04b715de2951a09bbf011b9189e0db Mon Sep 17 00:00:00 2001 From: Sylwester Lachiewicz Date: Fri, 3 Apr 2026 21:15:36 +0200 Subject: [PATCH] Add comprehensive test coverage improvements MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Enhanced test coverage from 73% to 79% instruction coverage: - UrlUtils: 1→13 tests covering path normalization edge cases - Launcher: 7→20 tests covering getters/setters and argument handling - OsgiBundleStrategy: 3→19 tests covering loadClass, getResource, getResources - ParentFirstStrategy: 3→19 tests covering loadClass, getResource, getResources - Added JaCoCo plugin (0.8.12) for coverage reporting Key improvements: - Test corner cases in UrlUtils.normalizeUrlPath() - Test null handling and edge cases in strategies - Test unconfigured Launcher scenarios - Test argument variations (null, empty, array) Co-authored-by: Cerebras Agent <193945191+isaact-cerebras@users.noreply.github.com> Add comprehensive test coverage for exceptions, strategies, and integration scenarios - Add tests for all exception classes (ClassWorldException, DuplicateRealmException, NoSuchRealmException, ConfigurationException) - Add tests for all strategy implementations (SelfFirst, ParentFirst, OsgiBundle, StrategyFactory) - Add tests for ClassWorldListener notification mechanism - Add integration tests for edge cases and concurrency scenarios - Enhanced ClassWorldTest with 14 additional tests covering constructors, disposal, listeners, and realm management - Overall test count increased from 92 to 155 (+68%) Co-authored-by: Cerebras Agent <193945191+isaact-cerebras@users.noreply.github.com> --- pom.xml | 21 +- .../classworlds/ClassWorldExceptionTest.java | 41 ++++ .../ClassWorldIntegrationTest.java | 122 +++++++++++ .../classworlds/ClassWorldListenerTest.java | 132 ++++++++++++ .../plexus/classworlds/ClassWorldTest.java | 120 +++++++++++ .../plexus/classworlds/UrlUtilsTest.java | 97 +++++++++ .../launcher/ConfigurationExceptionTest.java | 69 ++++++ .../classworlds/launcher/LauncherTest.java | 135 ++++++++++++ .../realm/DuplicateRealmExceptionTest.java | 47 +++++ .../realm/NoSuchRealmExceptionTest.java | 47 +++++ .../strategy/OsgiBundleStrategyTest.java | 190 +++++++++++++++++ .../strategy/ParentFirstStrategyTest.java | 198 ++++++++++++++++++ .../strategy/SelfFirstStrategyTest.java | 38 ++++ .../strategy/StrategyFactoryTest.java | 68 ++++++ 14 files changed, 1324 insertions(+), 1 deletion(-) create mode 100644 src/test/java/org/codehaus/plexus/classworlds/ClassWorldExceptionTest.java create mode 100644 src/test/java/org/codehaus/plexus/classworlds/ClassWorldIntegrationTest.java create mode 100644 src/test/java/org/codehaus/plexus/classworlds/ClassWorldListenerTest.java create mode 100644 src/test/java/org/codehaus/plexus/classworlds/launcher/ConfigurationExceptionTest.java create mode 100644 src/test/java/org/codehaus/plexus/classworlds/realm/DuplicateRealmExceptionTest.java create mode 100644 src/test/java/org/codehaus/plexus/classworlds/realm/NoSuchRealmExceptionTest.java create mode 100644 src/test/java/org/codehaus/plexus/classworlds/strategy/OsgiBundleStrategyTest.java create mode 100644 src/test/java/org/codehaus/plexus/classworlds/strategy/ParentFirstStrategyTest.java create mode 100644 src/test/java/org/codehaus/plexus/classworlds/strategy/SelfFirstStrategyTest.java create mode 100644 src/test/java/org/codehaus/plexus/classworlds/strategy/StrategyFactoryTest.java diff --git a/pom.xml b/pom.xml index 9e2646b..938c5af 100644 --- a/pom.xml +++ b/pom.xml @@ -127,7 +127,7 @@ maven-surefire-plugin true - -ea:org.codehaus.plexus.classworlds + -ea:org.codehaus.plexus.classworlds @{argLine} 1 @@ -163,6 +163,25 @@ + + org.jacoco + jacoco-maven-plugin + 0.8.12 + + + + prepare-agent + + + + report + + report + + test + + + diff --git a/src/test/java/org/codehaus/plexus/classworlds/ClassWorldExceptionTest.java b/src/test/java/org/codehaus/plexus/classworlds/ClassWorldExceptionTest.java new file mode 100644 index 0000000..472b63f --- /dev/null +++ b/src/test/java/org/codehaus/plexus/classworlds/ClassWorldExceptionTest.java @@ -0,0 +1,41 @@ +package org.codehaus.plexus.classworlds;
