In order to start testing, we’ll use a simple function like the tester function in the picture. The unit test is made through a Test_class, that contains all the methods we want to test. That is, we’ll be using the Microsoft CppUnitTest Framework, which is one of many available unit testing frameworks available for C++, we’ll talk about others later. You’ll find a CppUnitTest header included at the top. Once you, in, you’ll find two source files, go to the unittest1.cpp file. You’ll then be prompted to choose the test type, we’ll go for Native Unit Testing now. Open a new project in the visual studio panel, and under the C++ tab, choose the test collection. And it will most likely prove to be waste of time, most frameworks nowadays (we’ll talk about them later) offer almost everything you’d need, so there’s no need to reinvent the wheel.

Do not test the parts of your code that aren’t going to break.Do not attempt to test the entire input space, this will only prove to be a waste of time.Here are a few guidelines to follow when doing unit testing: Generally speaking, there are cases when unit testing is not necessary. However, there’s a very common misconception of either overdoing unit testing, or under-doing it. On the long run, it prevents the code from breaking functionalities when new features are added, and if something goes wrong, you’ll know exactly where did it happen, and maybe even why it did. It does, of course, come at the expense of some development time, but in the end, it’s absolutely worth it. Rather than doing the good-old-fashioned testing method of setting breakpoints and jumping to the GUI to test some inputs praying that it works altogether, you write the code for the test you want to make and get results faster than the traditional way, in addition, you can run them as much as you like. In some ways, Unit testing makes your code writing even faster than normal. When you get into the unit testing mentality, you’ll always be optimizing your code whilst keeping the tests in mind which results in breaking the code into precise pieces each doing a specific function rather than having one fuzzy big function doing everything. There are many key advantages to using Unit Testing.įirst of all, it prepares your code for proper modularity and reusability. By creating a test-suite for all the pieces within your code, you can use unit testing iteratively within the development, that is to assure that everything is still functioning as it should even after the addition of the new lines of code.
The more accurate term here is “Fit properly”.

Unit testing aims to test the individual functionalities within your software to assert that everything is working properly as it should. What we’re going to focus on today is Unit Testing, which is a crucial step and a fundamental one for world-class software to excel. There are multiple types of testing phases that your code can undertake, each of which focuses on certain features of the code, but they are inseparable in the way that they cover each other’s blind spot. Writing unmanaged code in C++ -also known as native code- could be a hefty task, this is why adding testing to your development kit is almost as crucial as the code-writing itself. However, this tremendous level of flexibility and functionality is not an excuse for writing messy buggy code. In 2017, there were over 230 thousand pull requests for C++ projects as it ranked as one of the most popular languages on GitHub. Arguably, there’s not a single thing that you can not do in C++, and despite its old age, it’s still in heavy industrial use. You can find Saurabh on Twitter and Medium.Ĭ++ is, hands down, one of the most powerful and most flexible programming languages there is. Saurabh is one of the co-founders of hackr.io. 2 Running our first test in Visual Studio.1.1 Here are a few guidelines to follow when doing unit testing:.1 What is unit testing, when to use it?.
