使用 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

==20341==    by 0x580760: main (testunit.cpp:88)

我想这是因为添加到套件中的测试在主程序结束之前没有被删除。

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？

running my regression tests with valgrind I have this kind of report:

==20341==    by 0x580760: main (testunit.cpp:88)

I guess this is due the fact that Tests added to Suite are not removed before the main is over.

This is the way I register the test:

  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") );

How do I unregister those tests ?

CppUnit 文档建议 runner.addTest< /code> 拥有对其给出的任何测试的所有权。通过只提供 runner.addTest myTest 实例的一部分，您并没有提供任何方法让整个 myTest 实例在删除时得到清理。运行后手动删除可能也不起作用，因为runner也会尝试删除给定的myTest部分。

如果您只想运行特定测试或测试子集，则应该尝试使用 testName 参数.6/class_text_test_runner.html#a2" rel="nofollow noreferrer">TextRunner::run。

（如果您有时间和意愿，您可能想研究不同的单元测试框架。 UnitTest++ 和 Google Test 比 CppUnit 更新、更易于使用且功能更丰富。）
