如何在Google Test TearDown()中检查测试是否失败？

Question

在每次"基于文件的集成"测试结束时,我想清除相关文件的临时文件夹.

如果测试失败,我想将文件保留在那里,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,您可以这样做,::testing::Test::HasFailure()在您的灯具的测试案例中查询,并使用结果来计算灯具中可以查询的灯具中的故障TearDown().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();
}

并输出:

[==========] 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
