googletest

I would like to test some private methods using GoogleTest. class Foo { private: int bar(...) } GoogleTest allows a couple of ways of doing this. OPTION 1 With FRIEND_TEST : class Foo { private: FRIEND_TEST(Foo, barReturnsZero); int bar(...); } TEST(Foo, barReturnsZero) { Foo foo; EXPECT_EQ(foo.bar(...), 0); } This implies to include "gtest/gtest.h" in the production source file. OPTION 2 Declare a test fixture as a friend to the class and define accessors in the fixture: class Foo { friend class FooTest; private: int bar(...); } class FooTest : public ::testing::Test { protected: int bar(...)

Let GTEST_DIR be the environment variable storing the path to the googletest directory. (I cloned googletest-master from googletest's github repo .) I cd 'ed into $GTEST_DIR , did a mkdir build && cd build , then executed the following command : cmake .. -DCMAKE_C_COMPILER=$GNU-6.0.0/bin/gcc-6.0.0 -DCMAKE_CXX_COMPILER=$GNU-6.0.0/bin/g++-6.0.0 where GNU-6.0.0 is the path to my gnu install. This generated a Makefile inside $GTEST_DIR/build that I tweaked as follows : I've added CC = $GNU-6.0.0/bin/gcc-6.0.0 CXX = $GNU-6.0.0/bin/g++-6.0.0 at its beginning, to be sure that the c and c++ compilers

I've written a small test with a mocked class. When I run it, first I get the warning that an uninteresting mock function was called and then the test fails because the expectation is not met, which is that the mocked function is called at least once. The funny thing is that that function is called as I see that warning message above. Do you have any ideas on this matter? Thank you! Edit: This is my code structure: class Bla { public: Bla(); virtual ~Bla(); virtual float myFunction(); } class MockBla : public Bla { MockBla(); ~MockBla(); MOCKMETHOD0(myFunction, float()); } class CallerClass {

I am currently writing unit tests for an embedded application using googles unit test framework . Now my boss got upset that the data I test with (i.e. the values with which I call methods of the class under test) is hard wired in the tests. He requests to have this data read-in from a file. His argument is that it would thus be easier to add another test for a corner case that was previously forgotten. I am not that experienced with unit tests but so far that was not how I did it. So I tried to figure out what would be the best way to do it - even if it is a good idea to do it at all. I

I am unable to use Google Test's ASSERT_THROW() macro in combination with multiple template arguments. Consider that I want to make sure that construction of Matrix<5,1> throws: ASSERT_THROW(Matrix<5,1>(), std::runtime_error); (this example doesn't make a lot of sense, of course this shoud not throw, but it is what stayed after simplifying what I had.) I get this output from MS VC++ 2008: warning C4002: too many actual parameters for macro 'ASSERT_THROW' error C2143: syntax error : missing ',' before ';' Whereas there are no problems with: ASSERT_THROW(Matrix<1>(), std::runtime_error); How can
