<h1>HTTP Feature Testing<a class="headerlink" href="#http-feature-testing" title="Permalink to this headline">¶</a></h1>
<p>Feature testing allows you to view the results of a single call to your application. This might be returning the
results of a single web form, hitting an API endpoint, and more. This is handy because it allows you to test the entire
life-cycle of a single request, ensuring that the routing works, the response is the correct format, analyze the results,
and more.</p>

<p>Essentially, the FeatureTestCase simply allows you to call an endpoint on your application and get the results back.
to do this, you use the <code class="docutils literal notranslate"><span class="pre">call()</span></code> method. The first parameter is the HTTP method to use (most frequently either GET or POST).
The second parameter is the path on your site to test. The third parameter accepts an array that is used to populate the
superglobal variables for the HTTP verb you are using. So, a method of <strong>GET</strong> would have the <strong>$_GET</strong> variable
populated, while a <strong>post</strong> request would have the <strong>$_POST</strong> array populated.</p>

<p>Responses will frequently contain JSON responses, especially when working with API methods. The following methods
can help to test the responses.</p>
<p><strong>getJSON()</strong></p>
<p>This method will return the body of the response as a JSON string:</p>
<div class="highlight-html+php notranslate"><div class="highlight"><pre><span></span><span class="c1">// Response body is this:</span>
<span class="p">[</span><span class="s1">&#39;foo&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;bar&#39;</span><span class="p">]</span>

<span class="nv">$json</span> <span class="o">=</span> <span class="nv">$result</span><span class="o">-&gt;</span><span class="na">getJSON</span><span class="p">();</span>

<span class="c1">// $json is this:</span>
<span class="p">{</span>
    <span class="s2">&quot;foo&quot;</span><span class="o">:</span> <span class="s2">&quot;bar&quot;</span>

</pre></div>
</div>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">Be aware that the JSON string will be pretty-printed in the result.</p>
</div>
<p><strong>assertJSONFragment(array $fragment)</strong></p>
<p>Asserts that $fragment is found within the JSON response. It does not need to match the entire JSON value.</p>
<div class="highlight-html+php notranslate"><div class="highlight"><pre><span></span><span class="c1">// Response body is this:</span>
<span class="p">[</span>
    <span class="s1">&#39;config&#39;</span> <span class="o">=&gt;</span> <span class="p">[</span><span class="s1">&#39;key-a&#39;</span><span class="p">,</span> <span class="s1">&#39;key-b&#39;</span><span class="p">]</span>

</div>
<p><strong>assertJSONExact($test)</strong></p>
<p>Similar to <strong>assertJSONFragment()</strong>, but checks the entire JSON response to ensure exact matches.</p>
