Joomla is an open-source content management system (CMS) that enables users to create and manage websites and web-based applications without extensive coding knowledge, utilizing a graphical user interface. Developed using PHP, it supports databases like MySQL and PostgreSQL and offers features such as content management, user management, media handling, and search capabilities. Despite being the fifth most popular CMS as of 2022, Joomla is often compared to WordPress for its complexity and steeper learning curve. Joomla provides a range of templates for different industries, such as business, e-commerce, and health, which can be easily swapped if users are unsatisfied with their website's appearance. While Joomla supports multilingual content and scalability for various project sizes, it faces challenges in media management and full customization. Testing Joomla websites is crucial for ensuring security, performance, and functionality, and can be performed using methods like manual and automated testing on platforms like LambdaTest. This testing platform offers a cloud-based infrastructure for comprehensive testing across numerous browser and device combinations, which enhances the scalability and reliability of Joomla website management.
