+ <a href="#summary">Quick summary</a> + of the SimpleTest tool for PHP. + </li> +<li> + <a href="#features">List of features</a>, + both current ones and those planned. + </li> +<li> + There are plenty of <a href="#resources">unit testing resources</a> + on the web. + </li> +</ul> +<div class="content"> + <p><a class="target" name="summary"><h2>What is SimpleTest?</h2></a></p> + <p> + The heart of SimpleTest is a testing framework built around + test case classes. + These are written as extensions of base test case classes, + each extended with methods that actually contain test code. + Top level test scripts then invoke the <span class="new_code">run()</span> + methods on every one of these test cases in order. + Each test method is written to invoke various assertions that + the developer expects to be true such as + <span class="new_code">assertEqual()</span>. + If the expectation is correct, then a successful result is dispatched to the + observing test reporter, but any failure triggers an alert + and a description of the mismatch. + </p> + <p> + A <a href="unit_test_documentation.html">test case</a> looks like this... +<pre> +<?php +require_once('simpletest/autorun.php'); + +class <strong>MyTestCase</strong> extends UnitTestCase { + <strong> + function testCreatedLogFile() { + $log = &new Log('my.log'); + $log->message('Hello'); + $this->assertTrue(file_exists('my.log')); + }</strong> +} +?> +</pre> + </p> + <p> + These tools are designed for the developer. + Tests are written in the PHP language itself more or less + as the application itself is built. + The advantage of using PHP itself as the testing language is that + there are no new languages to learn, testing can start straight away, + and the developer can test any part of the code. + Basically, all parts that can be accessed by the application code can also be + accessed by the test code, if they are in the same programming language. + </p> + <p> + The simplest type of test case is the + <a href="unit_tester_documentation.html">UnitTestCase</a>. + This class of test case includes standard tests for equality, + references and pattern matching. + All these test the typical expectations of what you would + expect the result of a function or method to be. + This is by far the most common type of test in the daily + routine of development, making up about 95% of test cases. + </p> + <p> + The top level task of a web application though is not to + produce correct output from its methods and objects, but + to generate web pages. + The <a href="web_tester_documentation.html">WebTestCase</a> class tests web + pages. + It simulates a web browser requesting a page, complete with + cookies, proxies, secure connections, authentication, forms, frames and most + navigation elements. + With this type of test case, the developer can assert that + information is present in the page and that forms and + sessions are handled correctly. + </p> + <p> + A <a href="web_tester_documentation.html">WebTestCase</a> looks like this... +<pre> +<?php +require_once('simpletest/autorun.php'); +require_once('simpletest/web_tester.php'); + +class <strong>MySiteTest</strong> extends WebTestCase { + <strong> + function testHomePage() { + $this->get('http://www.my-site.com/index.php'); + $this->assertTitle('My Home Page'); + $this->clickLink('Contact'); + $this->assertTitle('Contact me'); + $this->assertPattern('/Email me at/'); + }</strong> +} +?> +</pre> + </p> + + <p><a class="target" name="features"><h2>Feature list</h2></a></p> + <p> + The following is a very rough outline of past and future features + and their expected point of release. + I am afraid it is liable to change without warning, as meeting the + milestones rather depends on time available. + Green stuff has been coded, but not necessarily released yet. + If you have a pressing need for a green but unreleased feature + then you should check-out the code from Sourceforge SVN directly. + <table> +<thead> + <tr> +<th>Feature</th> +<th>Description</th> +<th>Release</th> +</tr> + </thead> +<tbody> +<tr> + <td>Unit test case</td> +

testing</h2></a></p> + <p> + Process is at least as important as tools. + The type of process that makes the heaviest use of a developer's + testing tool is of course + <a href="http://www.extremeprogramming.org/">Extreme Programming</a>. + This is one of the + <a href="http://www.agilealliance.com/articles/index">Agile Methodologies</a> + which combine various practices to "flatten the cost curve" of software development. + More extreme still is <a href="http://www.testdriven.com/modules/news/">Test Driven Development</a>, + where you very strictly adhere to the rule of no coding until you have a test. + If you're more of a planner, or believe that experience trumps evolution, + you may prefer the + <a href="http://www.therationaledge.com/content/dec_01/f_spiritOfTheRUP_pk.html">RUP</a> approach. + I haven't tried it, but even I can see that you will need test tools (see figure 9). + </p> + <p> + Most unit testers clone <a href="http://www.junit.org/">JUnit</a> to some degree, + as far as the interface at least. There is a wealth of information on the + JUnit site including the + <a href="http://junit.sourceforge.net/doc/faq/faq.htm">FAQ</a> + which contains plenty of general advice on testing. + Once you get bitten by the bug you will certainly appreciate the phrase + <a href="http://junit.sourceforge.net/doc/testinfected/testing.htm">test infected</a> + coined by Eric Gamma. + If you are still reviewing which unit tester to use you can find pretty complete + lists from + <a href="http://en.wikipedia.org/wiki/List_of_unit_testing_frameworks">Wikipedia</a>, + <a href="http://www.testingfaqs.org/t-unit.html">Software testing FAQ</a>, + and <a href="http://www.opensourcetesting.org/functional.php">Open source testing</a>. + </p> + <p> + There is still very little material on using mock objects, which is a shame + as unit testing without them is a lot more work. + The <a href="http://www.sidewize.com/company/mockobjects.pdf">original mock objects paper</a> + is very Java focused, but still worth a read. + The most authoritive sources are probably + <a href="http://mockobjects.com">the original mock objects site</a> and + <a href="http://jmock.org/">JMock</a>. + Java centric, but tucked away in PDFs they contain some deep knowledge on using mocks from the + extended experience of the concept inventors. + As a new technology there are plenty of discussions and debate on how to use mocks, + often on Wikis such as + <a href="http://xpdeveloper.com/cgi-bin/oldwiki.cgi?MockObjects">Extreme Tuesday</a> + or <a href="http://www.mockobjects.com/MocksObjectsPaper.html">www.mockobjects.com</a> + or <a href="http://c2.com/cgi/wiki?MockObject">the original C2 Wiki</a>. + Injecting mocks into a class is the main area of debate for which this + <a href="http://www-106.ibm.com/developerworks/java/library/j-mocktest.html">paper on IBM</a> + makes a good starting point. + </p> + <p> + There are plenty of web testing tools, but the scriptable ones + are mostly are written in Java and + tutorials and advice are rather thin on the ground. + The only hope is to look at the documentation for + <a href="http://httpunit.sourceforge.net/">HTTPUnit</a>, + <a href="http://htmlunit.sourceforge.net/">HTMLUnit</a> + or <a href="http://jwebunit.sourceforge.net/">JWebUnit</a> and hope for clues. + There are some XML driven test frameworks, but again most + require Java to run. + </p> + <p> + Most significant is a new generation of tools that run directly in the web browser + are now available. + These include + <a href="http://www.openqa.org/selenium/">Selenium</a> and + <a href="http://wtr.rubyforge.org/">Watir</a>. + They are non-trivial to set up and slow to run, but can essentially test anything. + As SimpleTest does not support JavaScript you would probably + have to look at these tools anyway if you have highly dynamic + pages. + </p> + + </div> + References and related information... + <ul> +<li> + <a href="unit_test_documentation.html">Documentation for SimpleTest</a>. + </li> +<li> + <a href="http://www.lastcraft.com/first_test_tutorial.php">How to write PHP test cases</a> + is a fairly advanced tutorial. + </li> +<li> + <a href="http://simpletest.org/api/">SimpleTest API</a> from phpdoc. + </li> +</ul> +<div class="menu_back"><div class="menu"> +<a href="index.html">SimpleTest</a> + | + <span class="chosen">Overview</span> + | + <a href="unit_test_documentation.html">Unit tester</a> + | + <a href="group_test_documentation.html">Group tests</a> + | + <a href="mock_objects_documentation.html">Mock objects</a> + | + <a href="partial_mocks_documentation.html">Partial mocks</a> + | + <a href="reporter_documentation.html">Reporting</a> + | + <a href="expectation_documentation.html">Expectations</a> + | + <a href="web_tester_documentation.html">Web tester</a> + | + <a href="form_testing_documentation.html">Testing forms</a> + | + <a href="authentication_documentation.html">Authentication</a> + | + <a href="browser_documentation.html">Scriptable browser</a> +</div></div> +<div class="copyright"> + Copyright<br>Marcus Baker 2006 + </div> +</body> +</html> |
