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 -.

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