- Written by one of the Agile Manifesto co-authors
- Very clean code, tests in /test directory
- Not as well known, but might be easier for students to understand

http://www.sqlite.org/testing.html
- Superb write up by SQLite of how they do extensive testing, but its possibly not developed with TDD principles, or maybe partially.

https://dzone.com/articles/Write-JUnit-Tests-in-Spring-With-Mocked-and-Real-Objects
- It looks decent, but I think the site is copyright encumbered :-/ all content on it is proprietary in their submission legal text
- I have read that referencing material for learning purpose can fall under Fair Use law, but its a gray area

http://www.codeaffine.com/2014/08/12/junit-in-a-nutshell-hello-world/
- A superbly written step-by-step walk through of creating a test and then creating the associated functional code
- It uses JUnit, which is an open source technology - but it uses a helloworld example - not sure if we want this or more of an integration with an existing oss project
- Unknown copyright beyond a ©

- These are a great series of TDD "Practice Exercises"; It gives you requirements that you are supposed to serially step through and implement on top of each other
- This uses open source, but it isn't involved in any existing oss project
- Unknown copyright

https://github.com/orfjackal/tdd-tetris-tutorial
- Tetris based TDD
- It gives you test cases, already written, and you code to satisfy the tests
- License says "You may use and modify this material freely for personal non-commercial use. This material may NOT be used as course material without prior written agreement."

TDD

Idea 1: Find a project that already has a testing harness and associated tests; learn it, and add a new unit test
Idea 2: Create a test harness to make, build, and run unit tests on an existing open source project
- Jim Bowring has done this in the past, though it seems they are lengthy projects vs a shorter activity; Do we want to create a “project”-oriented LA?
Idea 3: Use an existing JUnit exercise / tutorial to teach a simple TDD test first, code after scenario

Teach the “mental discipline” of testing
How can we test a Requirement?
- Ensuring testing starts at user requirement gathering
- Iterating through tests once code has been written, helps to improve the tests

Dave thinks ManageIQ does unit testing
Background reading:
- http://www.cs.cofc.edu/~bowring/ - course in testing
- Boris Byser - the test guru
- Kent Beck - extreme programming (ford motor)
- http://foss2serve.org/index.php/Test_Coverage_Activity
