Historical note: Before February 2016 *_EQ had a convention of calling it as ASSERT_EQ(expected, actual), so lots of existing code uses this order. Now (2020) *_EQ treats both parameters in the same way. However, when possible, ASSERT_EQ(actual, expected) is preferred. (gtests docs)

why set the field to a pointer (BankAccount*) instead of just the object itself at 4:56?

@RollerBladingSports Жыл бұрын

Without pointer you'll call it by value, but you should call it by reference. hope this one is still actual :D

This is ReSharper Unit Test Session tool window (www.jetbrains.com/help/resharper/2016.2/Using_Unit_Test_Sessions.html) If you have ReSharper and/or ReSharper C++ installed it should be available in ReSharper | Windows | Unit Test Sessions.

Why would you use Google Test over asserts or static_asserts?

@Bill-gc9bt 5 жыл бұрын

I understand that you're a genius at this stuff, but can you provide a reference for those of us that are new to google test? You know, where every single detail (no matter how small you think it is) is thoroughly explained. Feel free to tell me that I'm a lost cause, if that is indeed the case. Thanks in advance.

I use QtCreator IDE. You can setup GTest and GMock very quickly: 1) Select "File" > "New Project" > "Other Project" > "Auto Test Project". 2) Next, in drop down list ("Test framework") select "Google Test". Choose the source code folder of Google Test (that you get from GithUb) for example: "E:\Libs\googletest-release-1.10.0". Google Mock will be included too.

why not use class instead of struct?

@reysabs 5 жыл бұрын

Mostly in C++ use struct if you can to avoid possible memory leak cause struct is a valued type and it was manage by OS that means you dont need to release or delete.

@@reysabs I don't know where you're getting your "information" but that is not correct. Structs work exactly like classes except for the default visibility of members.

Im sorry I was referring for creating a Data structure. I used C++ for cross platform mobile development. IOS prefer struct over Class on this matters. I only use Class for methods or anything needs inheritance cause C#, Swift and Java doest support multiple inheritance.

I got a more important question: Why people use inheritance so much. It breaks encapsulation. Use composition as much as possible. People are thought wrongly in the past.

The tests are for future use so when you make changes the tests can verify that the results are still valid.

Imagine you have a program with 10 Millions lines of code written by dozens of different people and you want to add or change a feature or fix a bug. How do you do that and make sure you don't break the rest of the code base. Simple, you use tests.

@jayands 5 жыл бұрын

Tests are for when you go to modify the code. If you didn't write it, or even if you did but some time ago, you can look at it and see that this is what is supposed to happen. Combined with code coverage, it can eliminate a ton of bugs before they get released, both subtle and glaring. As an oversimplified example, ever been to r/GamePhysics on Reddit? Ideally, those could have been caught with unit and behavior testing
