Although software testing is encouraged before software designers embark on marketing their software, the fact remains that software testing does not thoroughly remove bugs and malfunctions. Designing software is a complex process. If it were not then the whole spectrum of creating software is as easy as 1-2-3, but this is not the case.
What software testing claims it does is it finds faults and errors in software. Additionally, it declares that it evaluates the capabilities of software functioning judging if it passes the required results. As a summary, it claims it detects error, validates and verifies software, estimates its reliability, and ultimately improving the quality of software.
In fact, bugs in software will exist in one way or another. For the reason that the complexity of the system will not ascertain ruling out defects and design malfunctions. Moreover, discerning defects in software or program is directly as complex as creating it in the first place. Not to mention the time it consumes to precisely examine even the simplest software. If these are not reason enough, there are other factors that affect the testing, such as timing, capricious human interaction, and input strictures.
What is more, if a single code is altered during the first stage of testing, the possibility of the entirety of the software changing is unavoidable. This is only one of the chances of a further complication. Take for example the California and eastern seaboard telephone outage that happened in 1991, disaster resulted after altering 3 lines of code in the signaling system.
As if the aforementioned are not enough, software testing actually does not have any stop to it. All the defects and possible design anomaly can never be removed; this is simply not possible and feasible. Truth be told, the reason why software testing is put to a halt is depletion of resources, may it be time finances or test methods. On the other hand, what the testers of software suppose is that the reliability of the software has met the requirement.
In the first place, the root of the problem which is complexity is also the reason why fixing it is unattainable. Moreover, the methods used for testing is not far different from what was used a couple of years ago, regardless of advancements in technology the methods are still very much alike. It also takes a lot of time, and experience coupled with techniques to make sure that testing software is competent.
To end, Newton’s third law of motion, “every action has an equal and opposite reaction” is applicable in software testing. Nevertheless, software testing is a technique that has been used for years now, and it still exists for a reason. Besides, software testing may bring more positive results as opposed to destruction, because the fact remains that it is still used at present. However, the downsides of software testing should be put into account and studied further. If the advantages of software testing outweigh its disadvantages, then software designs should undergo software testing.
