问题 How do I test that a function won't produce a segmentation fault? Here what I know right now, I can do: EXPECT_DEATH(foo(nullParameter)) In side the function, a segmentation fault is produce which is the behavior that I want to make fail. The snippet above will make the test pass because that is what is expected, the death of the process. Now, how can I make it fail? 回答1: Here's a function that will segfault if passed a null pointer argument and otherwise not: int deref(int * pint) { return

问题 How can I pass parameter to my test suites? gtest --number-of-input=5 I have the following main gtest code. And --number-of-input=5 should be passed to InitGoogleTest(). #include <iostream> #include <gtest/gtest.h> int main(int argc, char **argv) { std::cout << "Running main() from gtest_main.cc\n"; ::testing::GTEST_FLAG(output) = "xml:hello.xml"; testing::InitGoogleTest(&argc, argv); return RUN_ALL_TESTS(); } I don't know how to pass my parameter to the test suites/cases as follows? class

问题 I just started working on unit testing (using BOOST framework for testing, but for mocks I have to use Google Mock) and I have this situation : class A { static int Method1(int a, int b){return a+b;} }; class B { static int Method2(int a, int b){ return A::Method1(a,b);} }; So, I need to create mock class A, and to make my class B not to use real Method1 from A class, but to use mock. I'm not sure how to do this, and I could not find some similar example. 回答1: You could change class B into a

问题 I'm using the google test function EXPECT_EQ to run a test case for a function. The function, "find" returns a list and takes in a string of the name to find. Here's my test function: TEST_F(test_neighborhood, find) { list<Man> test; test.push_back(Man("username", "John", "Smith", 1, 1, "")); EXPECT_EQ(neighborhood.find("John"), test); } But when I try to "make", it gives me a long error /Library/Developer/CommandLineTools/usr/bin/../include/c++/v1/algorithm:665:71: error: invalid operands to

问题 I have a section of code that I would not like to run if it is being unit tested. I was hoping to find some #defined flag that is set by the gtest library that I can check. I couldn't find one that is used for that purpose, but after looking through the gtest header, I found one I thought I could use like this: SomeClass::SomeFunctionImUnitTesting() { // some code here #ifndef GTEST_NAME // some code I don't want to be tested here #endif // more code here } This doesn't seem to work as all

问题 I am generating a .sln with CMake. I want to use Google Test and use that kind of code for adding a new tests: add_executable(my_test test/my_test.cpp) target_link_libraries(my_test gtest gmock_main) add_test(NAME my_test COMMAND my_test) It works fine, but when I open my .sln, I have all the targets appearing in the solution explorer: the libraries, the unit tests, etc. Is there a way to hide these target? 回答1: You can't do it explicitly only in cmake (ATM), but here is one way on how can

问题 I am practicing google test C. I have a bit of confusion when writing a test case for function_1 function. typedef struct { int a; //4 byte char b; //1 byte char c; //1 byte char d; //1 byte char arr[3]; //3 byte }ABCXYZ; static void function_1(char *abc) { if (abc != null) { ABCXYZ *name =(ABCXYZ *)(abc + 4); if (name->b == 1) printf("ONE"); else if (name->b == 2) printf("TWO"); else printf("OTHER"); } else { printf("INVALID"); } } I have written test case like this: TEST(Test_function_1,abc

问题 Hello I am trying to access a private member function is Gtest . The code looks somewhat similar to this. So, how can I access static void Pri_fun ? using namespace std; class test{ }; class abc{ public: friend class test; private: static void Pri_fun() { cout << "private fun called \n"; } }; int main() { abc ab; test *abd; abd->Pri_fun(); } 回答1: Since it's a static function, you should access it via the class name: abc::Pri_fun(); You should make a caller function though, or call it from the

问题 I have used googletest for my Android NDK project contain .c files. I have used a test class of the type .cpp to do the same. I want to use .c file instead. I get the following error when I try to use it : Running main() from gtest_main.cc [==========] Running 0 tests from 0 test cases. [==========] 0 tests from 0 test cases ran. (1 ms total) [ PASSED ] 0 tests. How can i solve this? 回答1: You cannot use a .c file to write a test class in googletest instead of a .cpp file. A .c file should

问题 I have a basic question regarding Googletest in Eclipse. I am using the test-runner plug in to run the Googletests. But I need to specify a binary which runs my unit tests (of course that makes sense.) The problem is that in my project I now have two main functions, one to run the actual program and one int main(int argc, char** argv) { ::testing::InitGoogleTest(&argc, argv); return RUN_ALL_TESTS(); } to run the google tests. Each time I want to run one I comment the other out, which of
