			<content:encoded><![CDATA[<div class='snap_preview'><br /><h2><a href="http://tynerblain.com/blog/2008/01/09/testing-your-requirements/" rel="bookmark"><img src="http://www.smugmug.com/photos/241652946-L.jpg" align="left" />Why You Should Test Your Requirements</a></h2>
<p>We’ve written before about several <a href="http://tynerblain.com/blog/2006/05/25/writing-good-requirements-the-big-ten-rules/" title="writing good requirements">characteristics of well written requirements</a>, and one of those characteristics is <i>testability</i>.  Ahamad has written an <a href="http://testingsoftware.blogspot.com/2007/09/requirements-testing.html" title="tests of requirements">list</a> of 10 tests <i>of</i> requirements, with an emphasis on assessing the testability of the requirements. The testability of the requirement determines if the resultant product can be tested to determine if it meets the requirement. (&#8230;)</p>
<h2></h2>
<h2 class="title"><a href="http://blog.objectmentor.com/articles/2008/01/10/generated-tests-and-tdd">     Generated Tests and TDD</a></h2>
<p><span class="caps">TDD</span> has become quite popular, and many companies are attempting to adopt it. However, some folks worry that it takes a long time to write all those unit tests and are looking to test-generation tools as a way to decrease that burden.</p>
<p>The burden is not insignificant.  FitNesse, an application created using <span class="caps">TDD</span>, is comprised of 45,000 lines of Java code, 15,000 of which are unit tests.  Simple math suggests that <span class="caps">TDD</span> increases the coding burden by a full third!</p>
<p>Of course this is a naive analysis.  The <i>benefits</i> of using <span class="caps">TDD</span> are significant, and far outweigh the burden of writing the extra code. But that 33% still feels “extra” and tempts people to find ways to shrink it without losing any of the benefits. (&#8230;)</p>

			<content:encoded><![CDATA[<div class='snap_preview'><br /><p align="center"><em>(Aviso</em><em>! Esta não é mais uma nova técnica de programação)</em></p>
<p align="left">Um dos maiores obstáculos  na adoção do  Desenvolvimento Orientado a Testes, ou Test Driven Development (TDD) é justamente o termo <strong>“teste”</strong>.</p>
<p>Talvez tenha sido uma bola fora do Kent Beck ter colocado este nome, já que a principal vantagem desta abordagem não é validação de código e sim seu uso para projetá-lo. Como diz o Ron Jeffries, “o objetivo do TDD é escrever um código limpo e que funcione”, ou seja, usamos TDD para nos ajudar <strong>escrever </strong>código, e não simplesmente testá-lo.</p>
<p>Felizmente este problema de vocabulário não impediu a popularizacão da técnica, porém frameworks como o jUnit continuaram batendo na tecla dos “testes” usando termos como TestCase, TestSuite e obrigando ao programador começar todos os métodos com “test”. Isso colaborou ainda mais na associação de TDD com <strong>validação</strong>, ao invés de <strong>especificação</strong>.</p>
<p>Quando escrevemos um “teste” antes de sequer termos a implementação, estamos especificando o comportamento esperado do nosso código, definindo um contexto de entrada e avaliando se as saídas são as esperadas. Esta especificação automatizada, embora de baixo nível, ajuda principalmente na implementação do código, além de servir como ferramenta de validação.</p>
<p>Para tentar desassociar TDD apenas ao conceito de testes, surgiu o termo <strong>Behaviour Driven Development (BDD)</strong>, ou Desenvolvimento orientado a Comportamento. Também foram criados frameworks como o jBehave e RSpec para popularizar um novo vocabulário, mais condizente com os principais benefícios de TDD.</p>
<p>Alguns exemplos deste novo vocabulário incluem:</p>
<ul>
<li><strong><em>Context </em></strong>ao invés de <em>TestCase</em></li>
<li><strong><em>Specification </em></strong>ao invés de <em>Test</em></li>
<li><strong><em>Should </em></strong>ao invés de <em>Assert </em></li>
</ul>
<p>Quem já esteja acostumado com TDD e sabe exatamente o que esta técnica compreende talvez continue usando os seus termos, mas muitas confusões seriam evitadas se adotássemos este novo vocabulário.</p>
