Test Driven Development is a state of the art software development practice. When using TDD, programmers get instant feedback that the code they are writing does what they intend. An open source test harness is used to collect, organize and automate unit tests for your C++ code.
This class shows the motivations behind TDD, but does not stop there. Attendees get first hand experience at TDD. You will write code using TDD. You will see how tests can prevent many bugs. You will see how TDD can help programmers prevent memory leaks.

Students should bring laptops. We will pair program in the class, so solo's can team up.

Students are requested to visit the following website after August 1st and prior to the session: http://www.fitnesse.org/Agile2007TddCppPreparationPackage for setup instructions

Demo TDD

TDD Exercise Part 1 (students are given a series of tests to implement one at a time, these tests give them the feeling for the right size test in TDD.)

TDD Exercise Part 2 (students are given just the names of tests, and implement them one at a time)
