Peng's notes on cppunit

Introduction

CppUnit is a C++ unit testing module. It is a derivative of Java unit test module called JUnit. CppUnit was originally written by Michael Feathers. The wikipedia description of unit testing is here.

Some advantage of CppUnit over ad-hoc unit testing macros such as asserts are:

• Object oriented (most desired feature)
• Centered around unit testing as a concept
• Standard compiler-like text output
• Easy implementation and management (with Helper macros)
• Test registry to reduce recompilation needs

Download

Download Cppunit 1.12 at here

Install Cppunit 1) cd cppunit-1.12.0 2) ./configure (if not working, try ./configure --disable-shared) 3) make

Try the Money example (http://cppunit.sourceforge.net/doc/1.11.6/money_example.html)

Trouble shooting

in case you encounter the following error "fatal error - unable to remap..." when installing cppunit

To resolve it, do the following things in order: 1) Quit all cygwin processes 2) Start ash (\bin\ash.exe) 3) Execute /usr/bin/rebaseall

Compilation

To compile a cpp unit problem (example.cpp), we need to compile it with the following commands: g++ -g -O2 -c -o example.o example.cpp

Then compile the executable like this: g++ -g -O2 -o example.exe example.o -ldl -lcppunit

Run Tests (on cygwin)

Suppose we want to run the constraint engine test under cygwin. We should first enter the PLASMA directory: cd $PLASMA_HOME/src/PLASMA

Then we run the following jam command: jam -sLIBRARIES=STATIC -sOS=CYGWIN -sNOCYGWIN=TRUE run-ce-module-tests
