{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"🐞: allure-spock2 tests uuid conflicts during parallel tests execution","articleBody":"### What happened?\n\nThere is an issue with allure-results reporting during parallel tests execution using Spock framework:\n```groovy\n// File SpockConfig.groovy\nrunner {\n    parallel {\n        enabled true\n        dynamicWithReservedProcessors(1.0, 0)\n    }\n}\n```\n\nI am not 100% sure how to reproduce the issue, but with a large number of tests and with run in parallel, there is an issue, when allure-spock2 extension `AllureSpock2` reuses `ThreadLocal\u003cString\u003e testResults` with already defined initial UUID. It leads to the tests being registered with a non-unique UUID.\nThe symptoms are:\n```log\n2025-10-15 14:17:09,189 [ERROR] [ForkJoinPool-1-worker-9] [] - io.qameta.allure.AllureLifecycle.updateTestCase - Could not update test case: test case with uuid 4a4716fb-ada4-40ab-91a7-9fd615c19401 not found\n2025-10-15 14:17:09,189 [ERROR] [ForkJoinPool-1-worker-9] [] - io.qameta.allure.AllureLifecycle.stopTestCase - Could not stop test case: test case with uuid 4a4716fb-ada4-40ab-91a7-9fd615c19401 not found\n2025-10-15 14:17:09,189 [ERROR] [ForkJoinPool-1-worker-9] [] - io.qameta.allure.AllureLifecycle.writeTestCase - Could not write test case: test case with uuid 4a4716fb-ada4-40ab-91a7-9fd615c19401 not found\n```\nAnd there are fewer tests in the Allure report than were actually run.\n\nI've prepared the fix, but I do not have permissions to push into the repo.\n\nPlease, take a look at the fix below, and if you find it suitable - apply the fix.\n\n```java\n// allure-spock2/src/main/java/io/qameta/allure/spock2/AllureSpock2.java \n// instead of\nprivate final ThreadLocal\u003cString\u003e testResults = new InheritableThreadLocal\u003cString\u003e() {\n    @Override\n    protected String initialValue() {\n        return UUID.randomUUID().toString();\n    }\n};\n// use\nprivate final ThreadLocal\u003cString\u003e testResults = new ThreadLocal\u003c\u003e();\n\n// in beforeIteration\n@Override\npublic void beforeIteration(final IterationInfo iteration) {\n    final String uuid = UUID.randomUUID().toString();\n    testResults.set(uuid);\n    // ...\n}\n\n// in afterIteration\n@Override\npublic void afterIteration(final IterationInfo iteration) {\n    final String uuid = testResults.get();\n\n    if (uuid == null) {\n        return;\n    }\n\n    try {\n        getLifecycle().updateTestCase(uuid, testResult -\u003e {\n            if (Objects.isNull(testResult.getStatus())) {\n                testResult.setStatus(Status.PASSED);\n            }\n        });\n        getLifecycle().stopTestCase(uuid);\n        getLifecycle().writeTestCase(uuid);\n    } finally {\n        testResults.remove();\n    }\n}\n\n```\n\n### What Allure Integration are you using?\n\nallure-spock2\n\n### What version of Allure Integration you are using?\n\n2.30.0\n\n### What version of Allure Report you are using?\n\n2.12.0\n\n### Code of Conduct\n\n- [x] I agree to follow this project's Code of Conduct","author":{"url":"https://github.com/n1kolass","@type":"Person","name":"n1kolass"},"datePublished":"2025-10-15T16:39:17.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/1203/allure-java/issues/1203"}
