 is the practice of isolating a part of an application (typically a single module), and asserting that, given some inputs, it produces the expected outputs.</p>
<p>Testing a Mithril component is easy. Let&#39;s assume we have a simple component like this:</p>
<pre><code class="language-javascript">// MyComponent.js
var m = require(&quot;mithril&quot;)

module.exports = {
    view: function() {
        return m(&quot;div&quot;, 
            m(&quot;p&quot;, &quot;Hello World&quot;)
        )
    }
}</code></
