Question

在每次“基于文件的集成”测试结束时，我想清除关联文件的临时文件夹。

如果测试失败，我想将文件留在那里，这样我就可以查看意外的输出。

Google Test TearDown中是否有办法检查测试是否失败？

Google Test TearDown中是否有办法检查测试是否失败？

是的，你可以这样做来查询::testing::Test::HasFailure() 你的灯具的测试案例，并使用结果来计算一个柜台成员的失败可以在TearDown()中查询的灯具。一个基本的例子：

#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();
}

输出：

[==========] Running 2 tests from 1 test case.
[----------] Global test environment set-up.
[----------] 2 tests from Fixture
[ RUN      ] Fixture.foo
/home/imk/dev/so/gtest/main.cpp:19: Failure
      Expected: 1
To be equal to: 0
Fixture::TearDown sees failures
[  FAILED  ] Fixture.foo (0 sec)
[ RUN      ] Fixture.bar
[       OK ] Fixture.bar (0 sec)
[----------] 2 tests from Fixture (0.001 sec total)

[----------] Global test environment tear-down
[==========] 2 tests from 1 test case ran. (1 ms total)
[  PASSED  ] 1 test.
[  FAILED  ] 1 test, listed below:
[  FAILED  ] Fixture.foo

 1 FAILED TEST
