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.
In today’s world, an organization’s most valuable resource is its customers. However, acquiring new customers in an increasingly competitive marketplace can be challenging while maintaining a strong bond with existing clients. Implementing a customer relationship management (CRM) system will allow your organization to keep track of important customer information. This will enable you to market your services and products to these customers better.
How do we acquire knowledge? This is one of the seemingly basic but critical questions you and your team members must ask and consider. We are experts; therefore, we understand why we study and what we should learn. However, many of us do not give enough thought to how we learn.
Testing is a critical step in any web application development process. However, it can be an overwhelming task if you don’t have the right tools and expertise. A large percentage of websites still launch with errors that frustrate users and negatively affect the overall success of the site. When a website faces failure after launch, it costs time and money to fix.
Mobile application development is on the rise like never before, and it proportionally invites the need to perform thorough testing with the right mobile testing strategies. The strategies majorly involve the usage of various mobile automation testing tools. Mobile testing tools help businesses automate their application testing and cut down the extra cost, time, and chances of human error.
Learn to execute automation testing from scratch with LambdaTest Learning Hub. Right from setting up the prerequisites to run your first automation test, to following best practices and diving deeper into advanced test scenarios. LambdaTest Learning Hubs compile a list of step-by-step guides to help you be proficient with different test automation frameworks i.e. Selenium, Cypress, TestNG etc.
