Using google mock tests

ArduPlane Plane 4.3

I’m trying to develop more unit tests for specific modules. Testing the module itself is most of the times easy, however, when said module calls other modules it’s necessary to create a mock or override the function. Without the mock, the test enters into a segmentation fault.

I’m having problems with a module which is calling

gcs().send_text(MAV_SEVERITY_CRITICAL, “Lost manual control”);

I’ve tried using google mocks, but it throws an error when including the gmock.h the files. The following code is what I have tried to use to get it running. Including the gmock.h doesn’t work and using just the MOCK_METHOD doesn’t work either.

#include "gmock/gmock.h"

class MockGcs : public GCS {
 
    public:

        MOCK_METHOD(void, send_text, (MAV_SEVERITY severity, const char *fmt, ...));

    private:
        bool error_message_sent = false;
        bool notification_message_sent = false;
};

Thanks!
