CppUnit 泄漏

Question

用 valgrind 運行我的回歸測試我有這樣的報告：

==20341== 256 bytes in 1 blocks are indirectly lost in loss record 915 of 919

我想這是因為在主要結束之前沒有刪除添加到套件的測試。

這是我注冊測試的方式：

  CppUnit::TextTestRunner::TestRunner runner;

  // Get the top level suite from the registry
  CppUnit::Test* myTest = 
    CPPUNIT_NS::TestFactoryRegistry::getRegistry().makeTest();

  runner.addTest( myTest->findTest("TestVectorAlgebra") );

我如何取消注冊這些測試？

Answer 1

CppUnit 文檔表明runner.addTest擁有它所提供的任何測試的所有權。 通過給runner.addTest您MYTEST實例的只是一部分，你沒有提供任何方式為整個MYTEST執行個體上刪除清理。 運行后手動delete 'ing myTest 可能也不起作用，因為runner也會嘗試刪除它被賦予的myTest部分。

如果您只對運行特定測試或測試子集感興趣，則應嘗試使用TextRunner::run的testName參數。

（如果您有時間和興趣，您可能想研究不同的單元測試框架。UnitTest++和Google Test比 CppUnit 更新、更易於使用且功能更強大。）
