c++ - CppUnit - how use unique_ptr in setUp() -

the code taken http://cppunit.sourceforge.net/doc/cvs/cppunit_cookbook.html here creating pointers on heap , deleted them in teardown()

private:   complex *m_10_1, *m_1_1, *m_11_2; public:   void setup()   {     m_10_1 = new complex( 10, 1 );     m_1_1 = new complex( 1, 1 );     m_11_2 = new complex( 11, 2 );     }    void teardown()    {     delete m_10_1;     delete m_1_1;     delete m_11_2;   }    void testequality()   {     cppunit_assert( *m_10_1 == *m_10_1 );     cppunit_assert( !(*m_10_1 == *m_11_2) );   }    void testaddition()   {     cppunit_assert( *m_10_1 + *m_1_1 == *m_11_2 );   } }; 

but if use unique_ptr instead. lifetime of unique_ptr? deleted @ end of setup()? , should create instance in every test? possible avoid code duplication unique_ptr?

private:   std::unique_ptr<complex> m_10_1;   std::unique_ptr<complex> m_1_1;   std::unique_ptr<complex> m_11_2; public:   void setup()   {     m_10_1.reset(new complex(10, 1));     m_1_1.reset(new complex(1, 1));      m_11_2.reset(new complex(11, 2));     }    void teardown()    {    }    void test1()   {     // tests usage of ptr.     m_10_1.reset(new complex(10, 1)); // should here insted setup() ??   }    void test2()   {      // tests usage of ptr.     m_10_1.reset(new complex(10, 1)); // should here insted setup() ??   } }; 

those exist long containing object exists. unique_ptr's destructor called implicitly when containing object destroyed. whenever complexnumbertest destroyed, heap allocated objects well.

if have access c++14 consider using std::make_unique.
