googletest with global static variable

let's imagine we have the following code snippet

// myfile.c
#include myfile.h

static int global_static_value;

bool check_it(int value) {
   if (global_static_value== value) {
    return true;
   } else {
    return false
   }
}

void set_value(int value) {
   global_static_value = value;
}

// myfile.h

bool check_it(int value)
void set_value(int value)

How to write google test for function bool check_it(int value) in order to test true and false return value?

PS: It is not allowed to #include myfile.c into google test

Solution 
  • TEST_F(MyTestClass, MyTest)
{
    set_value(1);
    EXPECT_FALSE(check_it(2));
    EXPECT_TRUE(check_it(1));
}
