CppSpec is a behavior driven development (BDD) framework for C++. BDD is a refinement of TDD which turns the focus from writing the tests to the process of defining the behavior of the software using tests. You can read more about BDD from www.behaviour-driven.org.

CppSpec is licensed under Apache License, version 2.0.

To define behavior of your class you need to create a specifications for different states of your class. Specification is created by deriving from CppSpec::Specification class. Expectations for the behavior are written using specify method.

specify(should.be.empty()); 
specify(not should.be.empty());
specify(context().count(), should.equal(1));  

Exceptions are tested by calling a method which should throw an exception and verifying the result. For example:

specify(invoking(&Stack<int>::pop).should.raise.exception<std::exception>());

If the context implements iterator interface, you can specify that context should contain either unique items or sequences using contain keyword.

specify(should.contain("key"));
specify(should.contain(sequence.begin(), sequence.end()));

specify(context().asString(), should.match(pattern)); 

Building CppSpec requires CMake and Boost. See CMake documentation for more information about building using CMake.
