It validates the software system against the functional requirements/specifications. It mainly involves black box testing and is not concerned about the source code of the application.

– Just like a stern teacher, performance testing or perf testing, ensures that the system performs in terms of sensitivity, reactivity and stability under a particular workload. Using this method prior to the launch of your product can save you much time and money. It helps eliminate performance congestion, discover what is needed to be improved before launching, and confirm that it is stable and reliable.
The user-friendly test. Tested to see whether the software we are developing can be handled with ease by the users. After all, they are the end consumers and our target audience. Usability testing mainly focuses on user’s ease of using application, flexibility of application to handle controls and ability of application to meet its objectives. Aesthetics are important, and hence, visual appeal matters and so does the design. Testing during the initial stages can help identify usability errors in the system early in the development cycle and can save a product from failure. Gives you a run for your money, does it not?
A requisite, compatibility testing’s main aim is to verify whether the application is compatible with the client’s environment and to check whether your software is capable of running on different hardware, operating systems, applications, network environments or Mobile devices. At the end of the day, it is all about customer satisfaction. More and more people are turning to online resources to get them throughout the day. And what they hate – other than connectivity issues, is that ever-rotating cycle (loading…), error messages, non-user-friendly sites etc. So, let’s not disappoint them!
