Software Testing is very critical for the development of the software application and is most time consuming and difficult task to perform. Software Testing is as difficult as developing software because now days it requires more efforts, as everyone wants quality so Software Testing has become difficult because it takes lot of time and money.
Following are the reasons why Software Testing is considered as Difficult.
- Software Testing is hard and difficult because we need to test the software/application for both valid and invalid inputs and in Software Testing we also check the performance parameters as well as functionality too.
- During testing we always need to give the inputs in such a way that each and every line of the program/code is tested efficiently.
- Tester needs to give inputs randomly and ensure that the software/application never fails.
- Tester need to test the software by keeping the user perspective in mind means by keeping in mind how end user is using it and check whether the error messages displayed properly or not.
- Testers need to test the application/software by simulating the actual/real environment. Considering example if a database application has to be accessed by 200 users simultaneously, then it is not enough if you test the software/application for 5 0r 10 users and declare that application/software is working fine by leaving the software without checking all 200 users simultaneously.
- In several cases, it is not almost possible to test the software/application in real/actual environment. Considering example how do you test the software that is used in a satellite launch vehicle or a missile? You can do the complete testing only in a simulated environment.
