5. how to use

• vim gtest_demo.c

#include <gtest/gtest.h>
TEST(MathTest, TwoPlusTwoEqualsFour) {
    EXPECT_EQ(2 + 2, 4);
}

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

• run gtest_demo.c

$ export GTEST_HOME=/home/xxx/opt/gtest1.8.0
$ export LD_LIBRARY_PATH=$GTEST_HOME/lib:$LD_LIBRARY_PATH
$ g++ -I $GTEST_HOME/include -L $GTEST_HOME/lib -lgtest -lgtest_main -lpthread test.cpp
