<h2>Overview</h2>
<p>Rails is a web application framework that follows the Model-View-Controller (MVC) pattern, providing everything necessary for creating database-backed web applications. It divides the application into three layers - Model, View, and Controller, each with specific responsibilities.</p>
<h2>Features</h2>
<ul>
<li><strong>Model layer</strong>: Represents the domain model and encapsulates business logic. Can be either database-backed model classes or ordinary Ruby classes.</li>
<li><strong>View layer</strong>: Composed of templates responsible for displaying application resources. Views are typically HTML with embedded Ruby code (ERB files).</li>
<li><strong>Controller layer</strong>: Handles incoming HTTP requests and provides suitable responses. Can generate various formats like HTML, XML, JSON, etc.</li>
</ul>
<h2>Summary</h2>
<p>Rails is a robust web application framework that leverages the MVC pattern to organize and streamline the development of database-backed web applications. By providing clear separation of concerns and a set of powerful features like database integration, template rendering, and request handling, Rails simplifies the process of building dynamic and interactive web applications. Furthermore, Rails offers additional libraries like Action Mailer, Active Job, and Action Cable that further enhance the functionality and capabilities of Rails applications.</p>


<h2>Overview</h2>
<p>The Rails::Controller::Testing gem is a helpful tool for controller testing in Rails applications. It brings back the "assigns" method and the "assert_template" method, which were removed in Rails 5. The gem allows you to easily access and test instance variables passed to views.</p>
<h2>Features</h2>
<ul>
<li><strong>Brings back assigns:</strong> The gem restores the "assigns" method, which allows you to access instance variables passed to your views in controller tests.</li>
<li><strong>Restores assert_template:</strong> The gem also restores the "assert_template" method, which enables you to assert that particular templates have been rendered in your controller and integration tests.</li>
</ul>
