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 -.

Each test a function handles a small part of the test, and combined the functions test the whole thing. Declare them public along with the test functions.
Since we used the helper macro for test suite registration, test. We’ll see the importance of this name registration later. The function runTest is handled by the macros. It runs all the test suites and collects the results.
TestFixture Make the commonly used variables private. We need some new flags at the top of the file.
There are different types of asserts we can use in our test functions. We begin with the the test suite. CppUnit has a special class, called a fixture, for just this purpose.

The test function names begin with “test”. All of this goes in int main.
Our TestCase will have several instances of CartesianComplex that will cppjnit needed by all tests in the test case. The value a is the real part and b is the complex part.
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. This is but a small sample of what is available. We’ll call it TestCartesianComplexMath. Unit tests are code, separate and independent from the code it cppuniit, that can be run automatically.
We define the rest in the. TestResult controller; TestResultCollector result; controller.
CppUnit – Wikipedia
Our class will handle the basic math operations addition, subtraction, multiplication and division. It is a collection of tests run together as a unit. Our test class will extend CppUnit’s TestCase class. We also have a TestResult class which is the controller or event manager and a TestResultCollector class that listens for tests being run.
We’ll go over how to create each in CppUnit. Our tests are called from inside the runTest method. These flags will be used to tell the compiler where to find the CppUnit headers and declarations.
There are several parts of unit testing.
Some of the most common are: The only change we need to make in the Makefile is the linking of the files. TestFixture is a subclass of TestCase test cases. Adding these functions to the test case can be a little errorprone, but fortunately CppUnit has helper macros.
First we create a suite to run the tests. Notice that the registration name matched the class name. More can be found at the Wikipedia entry or about. The basic collection of tests is the TestCase class. TestCase TestCase has a virtual method void runTest we must override.
C will automatically call all linked and registered TestCase classes. The private variables should be created and destroyed in the respective TestFixture function. When the tests are run, it’ll give you documentaiton message. We will be using the latest stable version, release 1. If they all pass, you get an OK message.
