<h1>Calculator (Codeception)</h1>
<h2>NetBeans PHP Sample Application</h2>
<h3>What is Calculator?</h3>
<p class="p">Calculator is a simple calculator that supports basic arithmetical operations.
This PHP application is created to highlight PHP features supported by NetBeans IDE.
</p>
<p class="p">
<b>This sample is not intented to be used in a production environment without any changes.</b>
</p>
<h3>This sample demonstrates the following features:</h3>
<ul class="p">
<li>unit testing using Codeception</li>
<li>creating unit tests using <code>codecept generate:test command</code></li>
<li>code coverage of project files</li>
</ul>
<h3>Requirements</h3>
Follow these before you run the sample:
<ul class="p">
<li>Install NetBeans IDE with PHP support</li>
<li>Install and configure PHP Runtime</li>
<li>Install all dependencies using <a href="https://getcomposer.org/">Composer</a>
(click on project and invoke <i>Composer</i> > <i>Install (dev)</i>)<br>
<i>Note:</i> Codeception can also be installed <a href="http://codeception.com/install" target="_blank">globally as PHAR file</a></li>
<li>For debugging and code coverage, <a href="http://www.xdebug.org/">Xdebug</a> PHP extension is required</li>
</ul>
<h3>What is included?</h3>
<ul class="p">
<li>NetBeans <i>PHP Application</i> Project</li>
</ul>
<h3>Before the start</h3>
<ul class="p">
<li>If you want to try the sample out, follow <a href="#getting_started">Getting Started</a> guidelines.</li>
<li>In case if you want to try debugging features of the NetBeans IDE,
follow the <a href="#debugging">Debugging</a> guidelines.</li>
</ul>
<h3 id="getting_started">Getting Started</h3>
<ol class="p">
<li>
For the very first run, Codeception must be installed via Composer globally (see Requirements).
</li>
<li>
To initialize Codeception, Right-click the project node and select <i>Codeception > Bootstrap</i>.
</li>
<li>
Now, create a unit test for CalculatorEx class - open it in the editor
and select <i>Tools > Create/Update Tests</i>.
Then, select <i>test</i> command and <i>unit</i> suite in the Create Test dialog.
</li>
<li>
Add test cases for CalculatorEx class to the test class like CalculatorTest class.
</li>
<li>
To enable coverage put the below code in the unit suite configuration file <i>tests/unit.suite.yml</i>.
<pre><code>
coverage:
enabled: true
include:
- src/*
</code></pre>
</li>
<li>
Simply test the project. Right-click the project node and select <i>Test</i>.
IDE will inform you about the test results (window with test results can be opened manually).
</li>
<li>
For code coverage, open its report (right-click the project node and select <i>Code Coverage > Show Report...</i>)
and <i>Run All Tests</i> if there are no data available yet. Open <i>Calculator.php</i> file from the list of the files
to see which lines are and which lines are not tested.
</li>
<li>Play futher with the sample :)</li>
</ol>
<h3 id="debugging">Debugging</h3>
<p class="p">
These steps should enable you the debugging option at the sample project,
<a href="http://wiki.netbeans.org/HowToConfigureXDebug" target="_blank">if you already have PHP debugger (Xdebug)
installed and configured</a>.<br>
For demonstrating the PHP debugger in NetBeans, try the following:
</p>
<ol class="p">
<li>Open source class <i>Calculator.php</i> or <i>CalculatorTest.php</i> in the editor.</li>
<li>Put breakpoint on some line with PHP code.</li>
<li>To debug, right-click <i>CalculatorTest.php</i> and select <i>Debug</i>.</li>
</ol>
