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 -.

Adding these functions to the test case can be a little errorprone, but fortunately CppUnit has helper macros. Our test class will extend CppUnit’s TestCase class.
These vocumentation will be used to tell the compiler where to find the CppUnit headers and declarations. The test function names begin with “test”. We define the rest in the. There are several parts of unit testing. We’ll go over how to create each in CppUnit. First we create a suite to run the tests.
All of this goes in int main. The private variables should be created and destroyed in the respective TestFixture function. This is but a small sample of what is available. We’ll call it TestCartesianComplexMath. Since we used the helper macro for test suite registration, test. CppUnit has a special class, called a fixture, for just this purpose.
C will automatically call all linked and registered TestCase classes. We need some new flags at the top of the file. documemtation
More can be found at the Wikipedia entry or about. When the tests are run, it’ll give you a message. It runs all the test suites and collects the results. Some of the most common are: The function runTest is handled by the macros. Our tests are called from inside the runTest method.
Each test a focumentation 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.
The value a is the real part and b is the complex part. We also have a TestResult class which is the cppunir or event manager and a TestResultCollector class that listens for tests being run. The only change we need to make in the Makefile is the linking documengation the files. Unit tests are code, separate and independent from the code it tests, that can be run automatically.
We’ll see the importance of this name registration later.
Notice that the registration name matched the class name. If they all pass, you get an OK message. If one of them fails, it’ll tell you the name of the test case, the name of documentxtion source file and the cp;unit number. Our TestCase will have several instances of CartesianComplex that will be needed by all tests in the test case. TestFixture is a subclass of TestCase test cases. There are different types of asserts we can use in our test functions.

TestFixture Make the commonly used variables private. TestResult controller; TestResultCollector result; controller. We begin with the the test suite.
Declare them public along with the test functions. It is a collection of tests run together as a unit. The basic collection of tests is the TestCase class.
We will be using the latest stable version, release 1. Our class will handle the basic math operations addition, subtraction, multiplication and division.
