c++ - Gmock - how to override library function -


i trying override simple cmath library function - 'pow'

below code :

#include "stdafx.h" #include <gmock/gmock.h> #include <gtest/gtest.h> #include <cmath>  class powinterface { public:     virtual ~powinterface() {}     virtual double pow(double _xx, int _yx) = 0; };  class libxmock : public powinterface { public:     virtual ~libxmock() {}     mock_method2(pow, double(double _xx, int _yx)); };  int main() {      libxmock libxmockobj;      expect_call(libxmockobj, pow(10.00, 3));     double ans = libxmockobj.pow(10.00, 3);     expect_eq(2, ans); }

the code compiles fine execution gives below output:

c:\gmock> _test_example.cpp(36): error:       expected: 2 equal to: ans       is: 0 press key continue . . .

i unsure why returned value 0 - wondered if need add self definition of 'pow' method injected below code:

double pow(double _xx, int _yx) {     return libxmockobj.pow(_xx , _yx); }

now compiler fails compile code stating re-definition of pow method - hence how can implement own pow library method , call it?

i did not try compile, idea that:

#include "stdafx.h" #include <gmock/gmock.h> #include <gtest/gtest.h> #include <cmath>  class powinterface { public:     virtual ~powinterface() {}     virtual double pow(double _xx, int _yx) = 0; };  class libxmock : public powinterface { public:     virtual ~libxmock() {}     mock_method2(pow, double(double _xx, int _yx));     double custompow(double _xx, int _yx) {         return 2;     } };  int main() {      libxmock libxmockobj;      expect_call(libxmockobj, pow(10.00, 3)).times(1).willonce(::testing::invoke(libxmockobj, &libxmock::custompow));     double ans = libxmockobj.pow(10.00, 3);     expect_eq(2, ans); }

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
