如何在发行版中排除测试用例（gTest）

Question

If I'd use g(oogle)Test, these litte google macros like FRIEND_TEST(Test, Proc) are distributed everywhere in my code. Is there an automatism to exclude them from build, or do I really have to surround those with #ifdefs ?

Answer 1

You don't need to do anything of the sort. friend declarations are totally harmless and don't produce any overhead in production code.

Answer 2

You can have friend GTest cases, as mentionned here

As said, there is no overhead to using these macros.

Also, you can work around to test private class members without using FRIEND_TEST . One of them is to write accessors for the tested class' private members in the fixture class, then use the accessors in your tests:

class Foo {
  friend class FooTest;
  ...
};

class FooTest : public ::testing::Test {
 protected:
  ...
  T1 get_private_member1(Foo* obj) {
    return obj->private_member1_;
  }
};

TEST_F(FooTest, Test1) {
  ...
  get_private_member1(x)
  ...
}
