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 -.

CppUnit – The Unit Testing Library
Declare them public along with the test functions. First we create a suite to run the tests. These flags will be used to tell the compiler where to find the CppUnit headers and declarations. All of this goes in int main. TestResult controller; TestResultCollector result; controller.
This is but a small sample of what is available. Adding these functions to the test case can be a little errorprone, but fortunately CppUnit has helper macros.

Our tests are called from inside the runTest method. The value a is the real part and b is the complex part. We’ll see the importance of this name registration xppunit.
We need some new flags at the top of the file. Some of the most common are: We’ll call it TestCartesianComplexMath. We will be using the latest stable version, release 1. 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.
The basic collection of tests is the TestCase class. TestFixture Make the commonly used variables private. There are several parts of unit testing.
Our TestCase will have several instances of CartesianComplex that will be needed by all tests in the test case. The only change we need to make in the Makefile is the linking of the files.
The function runTest is handled by the macros. Our class will handle the basic math operations addition, subtraction, multiplication and division. When the tests are run, it’ll give you a message. TestFixture is a subclass of TestCase test cases.
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. Each test a function handles a small part of the test, and combined the functions test the whole thing. It is a collection of tests run together as a unit. TestCase TestCase has a virtual method void runTest we must override.
If they all pass, you get an OK message. The test function names begin with “test”. We begin with the the test suite. C will automatically call all linked and registered TestCase classes.
We’ll go over how to create each in CppUnit. Notice that the registration name matched the class name. Our test class will extend CppUnit’s TestCase class. We define the rest in the.
The private variables should be created and destroyed in the respective TestFixture function. CppUnit has a special class, called a fixture, for just this purpose.
Since we used the helper macro for test suite registration, test.
