Question

在NUnit中，TestFixtureSetup属性可用于标记在夹具中的任何测试之前应执行一次的方法。

CppUnit中是否有类似的概念？

如果没有，是否有支持这一概念的C ++单元测试框架？

根据下面的答案，这是一个实现这一点的例子（遵循this问题答案的建议）：

// Only one instance of this class is created.
class ExpensiveObjectCreator
{
public:
    const ExpensiveObject& get_expensive_object() const
    {
        return expensive;
    }

private:
    ExpensiveObject expensive;
};

class TestFoo: public CppUnit::TestFixture
{
    CPPUNIT_TEST_SUITE(TestFoo);
    CPPUNIT_TEST(FooShouldDoBar);
    CPPUNIT_TEST(FooShouldDoFoo);
    CPPUNIT_TEST_SUITE_END();

public:
    TestFoo()
    {
        // This is called once for each test
    }

    void setUp()
    {
        // This is called once for each test
    }

    void FooShouldDoBar()
    {
        ExpensiveObject expensive = get_expensive_object();
    }

    void FooShouldDoFoo()
    {
        ExpensiveObject expensive = get_expensive_object();
    }

private:
    const ExpensiveObject& get_expensive_object()
    {
        static ExpensiveObjectCreator expensive_object_creator;
        return expensive_object_creator.get_expensive_object();
    }
};

由于您无法使用fixture构造函数，这意味着CPPUnit正在使用每个测试的实例。我想你必须有一个方法和一个静态布尔标志，它被多次读取并且只在第一次写入。然后在构造函数中调用它。

CppUnit中的TestFixtureSetUp-like方法
