Google测试夹具

Question

我在试着了解Google测试夹具是如何工作的。

说我有下面的代码：

class PhraseTest : public ::testing::Test 
{ 
    protected: 
    virtual void SetUp() 
    {  
     phraseClass * myPhrase1 = new createPhrase("1234567890"); 
     phraseClass * myPhrase2 = new createPhrase("1234567890"); 
    } 

    virtual void TearDown() 
    { 
     delete *myPhrase1; 
     delete *myPhrase2; 
    } 
}; 



TEST_F(PhraseTest, OperatorTest) 
{ 
    ASSERT_TRUE(*myPhrase1 == *myPhrase2); 

} 

当我编译，为什么它说“myPhrase1”和“myPhrase2”是在TEST_F未申报？

Answer 1

myPhrase1和myPhrase2是本地的设置方法，而不是测试夹具。

你想要的是什么：

class PhraseTest : public ::testing::Test 
{ 
protected: 
    phraseClass * myPhrase1; 
    phraseClass * myPhrase2; 
    virtual void SetUp() 
    {  
     myPhrase1 = new createPhrase("1234567890"); 
     myPhrase2 = new createPhrase("1234567890"); 
    } 

    virtual void TearDown() 
    { 
     delete myPhrase1; 
     delete myPhrase2; 
    } 
}; 

TEST_F(PhraseTest, OperatorTest) 
{ 
    ASSERT_TRUE(*myPhrase1 == *myPhrase2); 

} 

Answer 2

myPhrase1和myPhrase2在SetUp函数中声明为局部变量。你需要把他们定义为类的成员：

class PhraseTest : public ::testing::Test 
{ 
    protected: 

    virtual void SetUp() 
    {  
    myPhrase1 = new createPhrase("1234567890"); 
    myPhrase2 = new createPhrase("1234567890"); 
    } 

    virtual void TearDown() 
    { 
    delete *myPhrase1; 
    delete *myPhrase2; 
    } 

    phraseClass* myPhrase1; 
    phraseClass* myPhrase2; 
}; 

TEST_F(PhraseTest, OperatorTest) 
{ 
    ASSERT_TRUE(*myPhrase1 == *myPhrase2); 
}
