Before we discuss the Joomla testing, let us understand the fundamentals of Joomla and how this content management system allows you to create and maintain web-based applications or websites without having to write and implement complex coding requirements.
Joomla is a content management system (CMS) that allows users to manage their applications or websites with the help of Graphical User Interface (GUI) without relying on writing coding.
It is an open source where you can build your website while connecting with databases such as MySQL and PostgreSQL. You are not required to learn a programming language’s fundamentals before starting with Joomla. It is developed using PHP, object-oriented programming, software design patterns, and databases for storing the data.
As of 2022, it is the fifth most used CMS on the Internet after WordPress, Shopify, Wix, and Squarespace.

Joomla released its first version (1.0) in 2005, which was supported till 2009. It was a rebranded release of Mambo 4.5.2.3, where some bug fixes and security updates were done.
In this guide on Joomla testing, learn what Joomla is, the features and key components of Joomla CMS, and how to test Joomla websites using different methods.
Joomla provides business, e-commerce, health, education, real estate templates, and many more. Here are some of the great Joomla templates you can use when designing your website:
This is why Joomla is used extensively compared to other content management systems. The templates play a vital role where you can design the front end in a rapid time. If you do not like the look and feel of the website, you can install other Joomla templates from various sources on the internet.
In this section of the Joomla testing guide, let’s look at the powerful in-built features of Joomla CMS.
Apart from providing excellent customer features, Joomla is one of the world’s most widely supported multilingual CMS platforms, supporting more than 70 languages. It also helps to provide much-needed scalability when you are handling small, medium, and large website projects.
With Joomla’s open-source community, you can get quick answers to technical queries. Apart from managing the website content, it is a great CMS for posting news, sharing information, and displaying images.
The Joomla platform has already provided support to millions of websites. But it does not mean you have to choose one particular reason when making a choice. The benefits are endless, and you can get your new website up and running in a speedy time. The future of Joomla as a powerful CMS looks promising.
There have always been challenges in making this CMS scalable. This is what Joomla developers are continuously trying to improve. They want the CMS to be lightweight and support scalability so that heavy traffic load can be managed easily.

Let us understand some of the disadvantages of using Joomla, which you should be aware of:
There are compatibility issues due to regular CMS updates.
Joomla components are the building blocks of the Joomla system. Once you install Joomla, core components are part of the system.
Here are some key elements related to Joomla:
Apart from the core components listed above, Joomla supports some third-party components.
There is a difference between Joomla modules and components. Joomla modules are different functionalities used to present information on your site. The components are full-blown applications that are usually more complex and help to improve the core functionality.
Let us try and compare the popular content management systems: Joomla or WordPress, and analyze which is the best based on different capabilities.
Let us try and compare Joomla vs. WordPress based on the different features they offer.
When you try and compare two options, it all comes down to different factors that create an impact in the long run. Joomla comes with a lot of built-in features as compared to WordPress, which is excellent from a usability perspective for an end user. WordPress is easier to use with substantial global community support. Most non-developers find it easier to build their website requirements with WordPress than with Joomla.
These are some prerequisites that can help you learn Joomla quickly:
The content and metadata of Joomla are stored in the MySQL database. Understanding the backend functionality can be much more challenging if you are unaware of databases. It is essential to know how CMS operates so you can easily understand the overall flow and navigation related to the websites being built.
To deliver the correct business value, performing end-to-end testing of Joomla websites is vital. Since it is an open-source content management system, it is highly prone to security vulnerabilities and attackers.
Here are the following benefits when you are performing Joomla testing.
It is always a good practice to perform Joomla testing before it is deployed in the actual production environment. It is recommended to validate and test your changes on the staging environment so that you are well aware of the deployment challenges that come along your way.

You can have a dedicated security team doing Joomla testing, as security is a crucial aspect of Joomla CMS.
Joomla testing can depend on the organization’s testing goals and objectives.
The developers can validate the code requirements to observe the exact system behavior. Once the development team gives the go-ahead, the QA team can perform the different testing levels along with the security team.
There are scenarios when you are adding more and more extensions for your Joomla website. A significant challenge with site loading or performance can impact the overall response time.
Here are some tricks you can follow to improve the website’s speed and performance.
