当 gtest 的宏出现故障ASSERT_，将调用或不调用 TearDown 函数

Question

当ASSERT_EQ在谷歌测试中失败时，会调用拆解函数吗？或者它只是取消该测试用例并移动到下一个测试用例而不进行拆解？这是因为在我的 TearDown 函数中，我需要做一些事情来正确关闭测试函数，所以我担心这个 ASSERT 会使我的测试不独立。

Answer 1

不

难满足自己，TearDown无论ASSERT_...宏是否失败：

测试用例.cpp

#include <gtest/gtest.h>
#include <iostream>
struct foo : ::testing::Test
{
    void SetUp()
    {
        std::cout << ">>>" << __PRETTY_FUNCTION__ << " was run " << std::endl;
    }
    void TearDown()
    {
        std::cout << ">>>" << __PRETTY_FUNCTION__ << " was run " << std::endl;
    }
};
TEST_F(foo,bar)
{
    ASSERT_EQ(1,0);
}
int main(int argc, char **argv) {
  ::testing::InitGoogleTest(&argc, argv);
  return RUN_ALL_TESTS();
}

编译和链接：

g++ -o testcase testcase.cpp -lgtest -pthread

跑：

$ ./testcase
