Is your website cross browser accessible? How you will make sure of that? By performing accessibility testing. But you must be aware of accessibility and accessibility testing for that first. Let’s unbox what is cross browser accessibility and how you can test it?
This article is for developers who are not that much comfortable in using JavaScript, but are comfortable in using HTML and CSS for web development. There is an incredible open source JavaScript library called Modernizr that can efficiently solve challenges faced in cross browser web development and based on test case scenarios, conditionally load JS or CSS files. Modernizr detects the CSS3 and HTML5 features supported by the browser of the end user. If you are smart, and have time to use this data, then you can develop webpages that behave differently based on this detection. For example you can detect if the rendering browser is Edge version 15 which does not support a specific function of your master CSS and based on that give a fallback CSS for not supported browsers
As per contemporary definition, risk is the occurrence of unfortunate events. Once it happens, the probability and potential of loss increases. In every software development life cycle, timely delivery of the product that comes with uncompromised quality is important. Hence, identification and prevention of risk is an important phase. In the testing phase, when risk management is planned efficiently it can help in the smooth flow of all other assignments. In the following article, we shall discuss the steps of risk management and some common risks and effective strategies for properly analyzing and preventing those risks.
API testing, a.k.a. Application Programming Interface testing, is the term which has garnered a growing attention in the past five years. It is a staple of any internet based product testing team, used for small stuff like image loading to huge stuff like payment processing.
