To get started with this blank TiddlyWiki, you'll need to modify the following tiddlers:
* SiteTitle & SiteSubtitle: The title and subtitle of the site, as shown above (after saving, they will also appear in the browser title bar)
* MainMenu: The menu (usually on the left)
* DefaultTiddlers: Contains the names of the tiddlers that you want to appear when the TiddlyWiki is opened
You'll also need to enter your username for signing your edits: <<option txtUserName>>
These InterfaceOptions for customising TiddlyWiki are saved in your browser

Your username for signing your edits. Write it as a WikiWord (eg JoeBloggs)

This tiddler contains a list of all problems collected so far.

* BowlingGame

* [[IntStack]]
* [[MultiMap]]
* NaturalSort
* [[Queue]]

A little more involved... Can bring up good discussion around how to test-drive implementation of a known algorithm (vs. derivation of a new algorithm).

!!(Right now I'm checking out communitywiki.org/odd -- it looks promising, check it out: [[TddProblems|http://www.communitywiki.org/odd/TddProblems/HomePage]])

This Tiddly-wiki was created based on the need to collaboratively collect problems suitable to learn the development technique called Test Driven Development, or TDD for short. It was created by Olof after the InitialThread on the ''testdrivendevelopment@yahoogroups.com'' mailing list.

We try to collect problems that are fun, real-world and somewhat good "playground" problems for TDD. That is, we try to avoid problems involving eg. ~GUI-development or database interaction, for starters at least.

The examples are expressed in english with some Java/C#/~VisualBasic-like syntax where needed.

Until we get a long list of examples, we will just list them here (no need to organize yet!): AllProblems.

If you want to learn about ~TiddlyWiki, visit [[GettingStarted]].

A reproduction of the original mailing list thread that spawned the idea of this site.

Rather than hijack my own thread I thought I would start a new one.
Based on a comment from Olaf I realized that there is a real lack of
problems that people use to learn/practice TDD.

Here are the ones I know of:

A list no but I seem remember
- that a lot of people like doing a TDD bowling game
- Ron has tried a number of different problems overtime on his blog:
seem to include Suduko, ...
- Brian Marick once proposed a non-trivial example - I think this might be
the link: www.exampler.com/writing/*tdd*-workbook.pdf

Please let me know what I'm missing and I will find a wiki of putting a list
up somewhere accessible.

Hi, Mark,

> Please let me know what I'm missing and I will find a wiki of putting a list
> up somewhere accessible.

Among my favorites are Range (very short and simple; integer range,
initially compels you to decide whether it's half-open, etc.; gets a
little interesting when you write overlaps(), which typically provides
some opportunities for refactoring) and NaturalSort (longer, but
straightforward and easy to understand, and to appreciate as a
real-world problem).

Natural Sort: <http://www.codinghorror.com/blog/archives/001018.html>

This is a great idea!

In fact, I had it too :)

So I've started a tiddlywiki (a mini-wiki that can be
downloaded/modified offline..) here:


Carl, may I add NaturalSort and Range as problems on
http://tdd-problems.tiddlyspot.com ?

Of course. Thanks for asking, but - I don't own these problems; have at 'em!

Here's a link to slides & code I wrote at a presentation for Natural
Sort, if you'd like to include it:


It wasn't designed for publication, so there may not be much value in
it, but - have a look, see whether there's anything there.

Thanks! I'll have a look.

The way I'm thinking now, tdd-problems.tiddlyspot.com should be a
collaborative collection of "basic" TDD problems, playground problems,
still somewhat real-world. Just good examples to learn TDD from.

Your two examples matches that precisely :)

I've already added the links, just have to fill in the problem statements.

Develop a class implementing the classic Stack datastructure containing integer values. That is, it should support the following operations:

# {{{Push(value)}}} - adds a value to top of the stack
# {{{value Pop()}}} - removes the top element of the stack and returns that value
# {{{int Count()}}} - returns the current number of elements contained in the stack

-- demonstrates technique well but solution is a bit too trivial, which can shortchange the value of TDD

A map whose values exist in a list. Great initial demo, has actual use in many projects. Similar to Apache Commons but not exactly the same.

 * Map<KeyType, List<KeyType>>
 * put(key, value)
 * get returns a list of KeyType objects
 * throw exception on null key
 * answers size (# of keys)
 * answers total # of values (across all keys)
 * answers isEmpty

Can add nuances such as disallows duplicate values, allows or disallows null values.
Built-in sorting algorithms in APIs seldom sort text string in the order expected by humans, for example when looking up a word in a dictionary or the yellow pages.

Here is an example:

__Builtin Sort__
Alpha 100
Alpha 2
Alpha 200
Alpha 2A
Alpha 2A-8000
Alpha 2A-900

__Natural Sort__
Alpha 2
Alpha 2A
Alpha 2A-900
Alpha 2A-8000
Alpha 100
Alpha 200

Develop an algorithm that sorts a list of string in the Natural Sort order. Hint: Split each string in groups of letters and groups of integers, and compare rows group-by-group.

Develop an integer range class. It should support

* access to maximum and minimum values.
* intersection of two ranges. The intersection of ranges [0..3] (0, 1, 2 & 3) and [2..4] is [2..3].
You can go both ways, either int to Roman or Roman to int.

For example, the roman number XVII is means 17.

Good demonstration of incremental development of an algorithm.
Requires a couple key insights, one around the use of a table, and one around thinking about the order of the tests
a collaborative TDD problem database
Test Driven Development Problems
We all know URLs, {{{http://www.google.se}}} is a popular one.

Develop a class that decomposes a given URL into its constituents. In the above example, we would like to get the result

# The protocol: "http"
# The domain name: "www.google.se"
# The path: an empty string in our example.
Bill Wake's Test-First Challenge (Jan. 2002) (http://xp123.com/xplor/xp0201/) is an early public TDD problem.  Notice that it predates the change in nomenclature from Test First to Test Driven.  This challenge also appeared on the Extreme Programming Yahoogroup where it was discussed by many participants.
Develop a class that represents a string set, supporting some basic set operations:

* Add element. 
* Checking if the set contains a specific string.
* Remove element.
* Element count.
* Union of two sets.
* Intersection of two sets.
* Clearing the set.

Develop a simple three-in-a-row game using TDD.

Hint: start out writing the "game rules" in some sort of Game class. It should have these operations:

# {{{Reset()}}} - clear all cells
# {{{bool IsEmpty(x,y)}}} - 'true' if cell (x,y) is empty
# {{{SetX(x,y)}}} - place an X in cell (x,y)
# {{{SetO(x,y)}}} - place an O in cell (x,y)
# {{{bool IsXWinner()}}} - 'true' if X has three-in-a-row
# {{{bool IsOWinner()}}} - 'true' if O has three-in-a-row

When you've built that game logic class, you can go on and implement a GUI or other interface for the logic. Or you can work out some smart AI algorithm, and ~TDD-build it.

Note, you also need UploadPlugin, PasswordOptionPlugin and LoadRemoteFileThroughProxy
from http://tiddlywiki.bidix.info for a complete working Tiddlyspot site.
