How to check if the test failed in Google Test TearDown()?
Is there a way in the Google Test TearDown to check if the test has failed?
Yes, you can do that be querying ::testing::Test::HasFailure()
in
the test cases of your fixture and using the result to tally failures in a counter member of
the fixture that can be queried in its TearDown()
. An elementary example:
#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();
}
And output:
[==========] Running 2 tests from 1 test case.
[----------] Global test environment set-up.
[----------] 2 tests from Fixture
[ RUN ] Fixture.foo
