Software testing is an integral part of any software development phase. Testing often accounts for more than 50% of the expenditure incurred in developing a particular software. The more complex is the software, the more time and resources need to be spent to make sure that flaws are detected and set right. However, often this is not the real picture.
Software or systems are often installed and rolled out with hundreds of defect in them. The result is poor performance and loss of many days both for the software development firm as well as the client. To avoid such problems team leads or managers must sort out some issues which are inherent to software testing. Let us go through 5 main software testing issues and methods to resolve them.
Testing is a time consuming affair. It has to be so since it is done to bring out the defects or inadequacies of the system under different conditions and not to show that it works. Testing needs to go hand in hand with development. This will make sure that inadequacies or errors in a particular functionality of the system is brought to the notice of the development team and sorted out sooner than later.
However, more often than not what happens is that managers keep on postponing testing until late in the development process. This leaves very little time for final testing which results in inadequate schedule of the process.
Tools and environments are backbones of proper software testing. However, testing is often carried out in inadequate testing environment. An over reliance on manual testing or COTS testing tools is another aspect. Moreover, some of the environmental components themselves suffer from defects. What is commonly seen is that test environment, test data and test software are not under adequate configuration control.
Often the mindset of the software testing team revolves around finding out functionality of the system rather than finding defects in it. This itself prohibits the team from finding out flaws in the software.
It is often seen that same type of problems are repeated in systems,projects after projects.
Often it is seen that testing and engineering processes are not properly integrated. This means that components or subsystems are often tested for flaws before they are mature enough to be tested on all parameters. Moreover, there may be some project specific needs that need to be looked into. One size fits all formula does not apply to software testing.
For letting us conclude, it is best said that unlike a single person, being a team is smarter. So, the best advice is to get together and fly high. Large enterprise and customers should not spend too much time accounting for errors which come up. Following a good and systematic practice for your QA needs will certainly provide quality to your team.
