Google測試夾具

Question

我在試着瞭解Google測試夾具是如何工作的。

說我有下面的代碼：

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); 

} 

當我編譯，爲什麼它說「myPhrase1」和「myPhrase2」是在TEST_F未申報？

Answer 1

myPhrase1和myPhrase2是本地的設置方法，而不是測試夾具。

你想要的是什麼：

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函數中聲明爲局部變量。你需要把他們定義爲類的成員：

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); 
}
