First Friends 2 Unit 2
Evelina Browder
My class has methods that are called by other methods; none of these methods should be called outside the class, so they should be private. Of course they could be put into one method, but logically they are much better separate. These methods are complicated enough to warrant unit testing, and due to performance issues I will very likely have to re-factor these methods, hence it would be nice to have a test to make sure that my re-factoring didn't break anything. I am not the only one working on the team, though I am the only one who is working on this project including the tests.
You can then use this specialization of access_by to call private methods of A. Basically, what this does is put the onus of declaring friendship into the header file of the class that wants to call A's private methods. It also lets you add friends to A without changing A's source. Idiomatically, it also indicates to whoever reads the source of A that A does not indicate B a true friend in the sense of extending its interface. Rather, the interface of A is complete as given and B needs special access into A (testing being a good example, I've also used this pattern when implementing boost python bindings, sometimes a function that needs to be private in C++ is handy to expose into the python layer for the implementation).
If you're worrying about your code coverage, you need to find configurations that allow you to test that private method from one of the public method calls. If you can't do that, what's the point of having the method in the first place? It's simply unreachable code.
There are a few options to do this, but keep in mind that they (in essence) modify the public interface of your modules, to give you access to internal implementation details (effectively transforming unit testing into tightly coupled client dependencies, where you should have no dependencies at all).
you could add #define private public to the beginning of your test files, before #include-ing the tested code. In case the tested code is an already-compiled library though, this could make the headers no longer match already compiled binary code (and cause UB).
you could insert a macro in your tested class and decide at a later date what that macro means (with a different definition for testing code). This would allow you to test internals, but it would also allow third party client code to hack into your class (by creating their own definition in the declaration you add).
Here's a questionable suggestion for a questionable question. I don't like the coupling of friend as then released code has to know about the test. Nir's answer is one way to alleviate that, but I still don't much like changing the class to conform to the test.
Since I don't rely on inheritance often, I sometimes just make the otherwise private methods protected and have a test class inherit and expose as needed. The reality is that the public API and the testing API can differ and still be distinct from the private API, which leaves you in sort of a bind.
Here's a practical example that's of the sort I resort to this trick for. I write embedded code, and we rely on state machines quite a bit. The external API doesn't necessarily need to know about the internal state machine state, but the test should (arguably) test conformance to the state machine diagram in the design doc. I might expose a "current state" getter as protected and then give the test access to that, allowing me to test the state machine more fully. I often find this type of class hard to test as a black box.
You can write classes and never have any private methods at all. All you need to then do is make implementation functions within the compilation unit, let your class call them and pass in any data members they need to access.
If I'm using a 3rd party library I'd rather not see friend declarations to their unit testers. I don't want to build their library either and have their tests run when I do. Unfortunately too many 3rd party open source libraries I have built do that.
However not all classes are visible to the user of your library. Lots of classes are "implementation" and you implement them the best way to ensure they work properly. In those, you may still have private methods and members but want unit testers to test them. So go ahead and do it that way if that will lead to robust code quicker, that is easy to maintain for those who need to do so.
Ginsberg, a first-time author, is a former attorney, member of the Clinton Administration and media executive. He received his undergraduate degree from Brown University and his law degree from Columbia University.
A few of the friendships explored in the book are those between Thomas Jefferson and James Madison, Abraham Lincoln and Joshua Speed, Daisy Suckley and Franklin Roosevelt and John F. Kennedy and David Ormsby-Gore, a British diplomat.

Sgt. Nicholas C. Mason and Sgt. David A. Ruhren, both assigned to the Fredericksburg-based 229th Brigade Engineer Battalion, 116th Infantry Brigade Combat Team, but were deployed with the 276th Engineer Battalion, 329th Regional Support Group, were killed in the attack in a mess tent on Forward Operating Base Marez, in Mosul, Iraq. A total of 22 people were killed, including 14 U.S. troops. Dozens of others suffered serious injuries, including others deployed with the 276th.
The group, which included the mothers of both fallen Soldiers, gathered at the Tomb of the Unknown Soldier. After the ceremonial changing of the guard, Sonja Ruhren and Christine Mason placed the wreath on a display in front of the tomb. That display included a picture of the two friends together.
After leaving Arlington National, the group continued on to Whipple Field on neighboring Fort Myer. There, family and friends filled dozens of red balloons with helium before sending them skyward in honor of the two fallen sergeants.
Sgt. Ruhren and Sgt. Mason were both 20 years old when a suicide bomber dressed as an Iraqi soldier walked into a mess tent on FOB Marez in Mosul, Iraq and detonated his explosive-laden vest. At a ceremony in 2014, 10 years later, the readiness center in Fredericksburg, Va. was remanded the Mason-Ruhren Readiness Center in honor of their sacrifice.
Mason, a native of King George, is survived by his father Vic Mason, mother Christine and sister Carly Mason. He was a 2002 honor graduate of King George High School where he was a star wrestler, cross-country runner and track athlete. He completed his freshman year at Virginia Tech and was preparing for his sophomore year before being called to active duty.
Ruhren, a native of Stafford, is survived by his mother Sonja. He graduated from Garfield Senior High School in 2002 where he was active in many extracurricular activities including wrestling and football. He was one of the first members of the Garfield Senior High School Marine Corps Junior ROTC Program when it was established, and was promoted to the rank of cadet lieutenant by the first semester. While serving in the Guard, he took classes to become an EMT at the Rock Hill Fire Department in Stafford.
The Masons have joined with the family of another fallen service member to form the Some Gave All Foundation, to benefit service members wounded, disabled or in need. They host an annual benefit ride, which was held this year in June.
In this unit, students read a collection of texts focused on what it means to be a good friend. This unit, in connection with beginning-of-the-year culture-building activities, will set a strong foundation for building social-emotional awareness as students navigate making new friendships within the classroom.
Students begin to build their fluency with daily writing in response to the Target Task question, learning how to take their understanding of a story and transfer that into writing. In this unit, students also have their first chance to explore narrative writing by writing about a time they were a good friend. Since this is the first process writing project of the year, the focus is on generating on-topic ideas with a beginning, middle, and end. Students also learn what an opinion is, and write an opinion piece about what it means to be a good friend.
Before you teach this unit, unpack the texts, themes, and core standards through our guided intellectual preparation process. Each Unit Launch includes a series of short videos, targeted readings, and opportunities for action planning to ensure you're prepared to support every student.
In order to ensure that all students are able to access the texts and tasks in this unit, it is incredibly important to intellectually prepare to teach the unit prior to launching the unit. Use the intellectual preparation protocol and the Unit Launch to determine which support students will need. To learn more, visit the Supporting all Students teacher tool.
