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 -.

We define the rest in the. First we create a suite to run the tests. C will automatically call all linked and registered TestCase classes.
We’ll see the importance of this name registration later. Our tests are called from inside the runTest method.
Adding these functions to the test case can be a documetation errorprone, but fortunately CppUnit has helper macros. The only change we need to make in the Makefile is the linking of the files.
The basic collection of tests is the TestCase class. When the tests are run, it’ll give you a message. Our TestCase will have several instances of CartesianComplex that will be needed by all tests in the test case.
The value a is the real part and b is the complex part. We’ll go over how to create each in CppUnit. We need some new flags at the top of the file. Notice documentahion the registration name matched the class name. Our class will handle the basic math operations addition, subtraction, multiplication and division.
There are different types of asserts we can use in our test functions.

We’ll call it TestCartesianComplexMath. Since we used the helper macro for test suite registration, test. We will be using the latest stable version, release 1. We also have a TestResult class which is the controller or event manager and a TestResultCollector class that listens for tests being run.
Declare them public along with the test functions. TestCase Dppunit has a virtual method void runTest we must override. It is a collection of tests run together as a unit. If they all pass, you get an OK message. These flags will be used to tell the compiler where to find the CppUnit headers and declarations.

The function runTest is handled by the macros. Unit tests are code, separate and independent from the code it tests, that can be run automatically. TestResult controller; TestResultCollector documentxtion controller. More can be found at the Wikipedia entry or about. We begin with the the test suite. All of this goes in int main.
TestFixture Make the commonly used variables private. Each test a function handles a small part of the test, and combined the functions test the whole thing.
The test function names begin with “test”. The private variables should be created and destroyed in the respective TestFixture function. Our test documeentation will extend CppUnit’s TestCase class. TestFixture is a subclass of TestCase test cases. If one of them fails, it’ll documentaton you the name of the test case, the name of the source file and the line number.
This is but a small sample of what is available. It runs all the test suites and collects the results. CppUnit has a special class, called a fixture, for just this purpose. Some of the most common are: There are several parts of unit testing.
