Software testing plays a critical and important process in quality assurance. Failed software not only results in wasted time, unsatisfied customers and a bad name for the company but also unnecessary costs, which is why it is important to plan and test software in many levels over. Brand and company name are not just a part of what is at stake during, or lack of, software testing. It is a big risk that companies take when they release a product to the market, as people expect that you only release a product when it is fully functional. This performs a domino effect on profit, as if brand and credibility are down, so is profit. Customers will always remember the quality associated with the brand or product, so software testing is a necessary investment.   

Not only is the testing process itself important, but also the design of the systems. Programmers must ensure that testing procedures and software are already in place prior to testing, because inaccurate testing methods can result in even more costs and time delays.  The software testing methods should include both hardware and software devices.  

Software testing is also costly, as this entails the use of specialized systems designed for the different processes of testing, but it is better to invest in good testing rather than suffer the consequences later. The costs are undoubtedly larger if errors are found at the later stages of producing software rather than in the earlier stages, so it pays to dedicate time and effort to software testing. The overall goal of software testing is to provide customers with quality software that is bug and error free.  

Software testing can only be accurate if it is checked through all aspects and levels of testing. Each level of testing is designed so that programmers or developers can find bugs or errors from even small units to the entire integration of the system, and so that this can be corrected. The results are compared to strict guidelines, which must be met and a mediocre attitude will only backfire on the company. 

It is important to only release a product that is not only free of bugs and error, but reliable, easy to use, and highly capable of producing the tasks it was made for. There are different approaches and procedures in software testing, as some prefer to do it in the early stages while it is being designed, while some prefer to test the overall product later on. It is probably safer to test much early on and to do this frequently, instead of using the finished product to test and work backwards. Not to mention, the higher in the designing phase that the bugs are detected, the higher the price as well. Years of software testing has shown that when errors are detected in the early phases of development, the cost for repair is much lower.

So just imagine how much more costly it is to work on testing or find bugs only at the end, or even worse, by a customer.
