Question

用valgrind运行我的回归测试我有这样的报告：

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

我想这是因为添加到Suite的测试在主要结束之前没有删除。

这是我注册测试的方式：

  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") );

如何取消注册这些测试？

Answer 1

CppUnit documentation表明runner.addTest取得了所有测试的所有权。通过仅为runner.addTest提供myTest实例的一部分，您无法提供任何方法让整个myTest实例在删除时进行清理。在运行后手动delete'运行myTest可能也不起作用，因为runner也会尝试删除已经给出的myTest部分。

如果您只想运行特定测试或测试子集，则应尝试使用TextRunner::run的testName参数。

（如果你有时间和倾向，你可能想要研究一个不同的单元测试框架。UnitTest++和Google Test比CppUnit更新，更容易使用，更有特色。）
