如何檢查Google Test TearDown（）中的測試是否失敗？

Question

在每個「基於文件的集成」測試結束時，我想清除關聯文件的臨時文件夾。

如果測試失敗，我想將文件保留在那裏，以便我可以查看意外輸出。

在Google Test TearDown中有沒有辦法檢查測試是否失敗？

在Google Test TearDown中有沒有辦法檢查測試是否失敗？

是的，你可以做，在 進行查詢::testing::Test::HasFailure()您的燈具的測試案例和使用結果的 相對部件可在其TearDown()查詢夾具相符故障。一個基本的例子：

#include <gtest/gtest.h> 
#include <iostream> 

struct Fixture : public ::testing::Test { 
    virtual void SetUp() { 
     fails = 0; 
    } 

    virtual void TearDown() { 
     if (fails > 0) { 
      std::cerr << "Fixture::TearDown sees failures" << std::endl; 
     } 
    } 

    unsigned fails; 
}; 

TEST_F(Fixture, foo) { 
    EXPECT_EQ(1,0); 
    fails += ::testing::Test::HasFailure(); 
} 
TEST_F(Fixture, bar) { 
    EXPECT_EQ(1,1); 
    fails += ::testing::Test::HasFailure(); 
} 

int main(int argc, char **argv) { 
    testing::InitGoogleTest(&argc, argv); 
    return RUN_ALL_TESTS(); 
} 

輸出：
