CppUnit is a unit testing framework module for the C++ programming language. It allows “CppUnit Documentation”. ^ Jenkins plug-in for CppUnit and other Unit Test tools; ^ fork presented as CppUnit v; ^ fork. This document gives a simple example of CppUnit. The content covers the download of CppUnit,an example of CppUnit, compilation and. Easy refactoring of code. The unit test is a form of documentation in cppunit. C++ framework. Derived from jUnit. Centered around unit testing as a concept -.

C will automatically call all linked and registered TestCase classes. The basic collection of tests is documentatikn TestCase class. We begin with the the test suite. It is a collection of tests run together as a unit.
The only change we need to make in the Makefile is the linking of the files. Since we used the helper macro for test suite registration, test.
Our test class will extend CppUnit’s TestCase class. If one of them fails, it’ll tell you the name of the test case, the name of the source file and the line number. There are several parts of unit testing.
We define the rest in the. First we create a suite to run the tests. Unit tests are code, separate and independent from the code documejtation tests, that can be run automatically. We will be using the latest stable version, release 1. TestFixture Make the commonly used variables private. If they all pass, you get an OK message.
We’ll go over how to create each in CppUnit. Notice that the registration name matched the class name. Our tests are called from inside the runTest method. Some of the most common are: It runs all the test suites and collects the results.
Declare them public along with the test functions. Each test a function handles a small part of the test, and combined the functions test the whole thing. TestCase TestCase has a virtual method void runTest we must override.
There are different types documenttation asserts we can use in our test functions. Our TestCase will have several instances of CartesianComplex that will be needed by all tests in the test case. We also have a TestResult class which is the controller or event manager and a TestResultCollector class that listens for tests docunentation run.
TestResult controller; TestResultCollector result; controller. These flags will be used to tell the compiler where to find the CppUnit headers and declarations. The private variables should be created and destroyed in the respective TestFixture function.
The test function names begin with “test”. We’ll call it TestCartesianComplexMath. More can be found at the Wikipedia entry or about. TestFixture is a subclass of TestCase test cases. We need some new flags at the top of the file. Adding these functions to the test case can be a little errorprone, but fortunately CppUnit has helper macros.
The value a is the real part and b is the complex part. This is but a small sample of what documentatin available.

Our class will handle the basic math operations addition, subtraction, multiplication and division. The function runTest is handled by the macros. All of this goes in int main. When the tests are run, it’ll give you a message. We’ll see the importance of this name registration later.
CppUnit has a special class, called a fixture, for just this purpose.
