What Is Software Testing?
Software testing is indeed a very important pre-release process for the software industry. In general terms, it means testing the entire software for its functionality and to check out that there are no glitches or bugs. With the software market being so very competitive in recent times, a small bug could also put a big dampener on the business prospects of the software product. But, software testing must be done very comprehensively.
There are many aspects of software quality testing that testers overlook. It is funny how even some professional testers do not know what software testing is. Three of the important aspects to look into are the compatibility, performance and security. These are where the major problems can come up.
Software Compatibility Testing
Professional testers have to make very sure that the software will be really functional with the system specifications it asks for. Software compatibility testing basically entails checking for functionality with said system and hardware configurations, but it is also important to check with a few of the prevailing older versions just in order to make sure. Here, the installation process needs to be checked, and also whether the software loads quickly enough. Slow loading software programs are much detested in the market. Hence, installability and usability are two main things to be checked during software compatibility testing.
Software Performance Testing Software performance testing involves running the whole program through its various testing stages, from alpha to beta. The task involves finding and fixing all errors that may crop up while working the program. In companies that hire professionals for software testing, the testing is generally done in the form of units. An example of this is freelance game testing, where separate levels of the game are given to the freelancer to check for snags and programming glitches. A lot of software performance testing is done by freelance operators from across the world in small units. When the unit testing is done, the tested units are integrated into the entire program. This entire program is checked once again to ensure that the separate units have merged seamlessly into the full running program. This part of the testing is known as integration testing. After integration testing, the software testing for the product is generally assumed to be completed, and the program become almost ready to be launched into the market. Sometimes, testers would run the whole program again after fixing a bug in the program. This is to find out whether fixing the bug has caused any other changes in the program. This kind of back-testing the product after fixing errors is known as regression testing. Regression testing is essential when the program contains a lot of features that are closely related with each other, such as games. Software security testing
Software security testing is very important to ensure protection to the user from Internet cheaters, hacks and even phishers. The Internet user of today is very wary of security. This is seen more abundantly in business related software that asks for identifying information to ensure their copies. The software needs to be checked very thoroughly to see that it will not attract Spyware from external agents, and will be self-protected from virus intrusions.
