Companies developing software always have the pressure to deal with deadlines. With so much of effort put behind a particular product, the entire project sometimes fail due lack in time for software testing. Deadlines often lead to reduction in time for software quality assurance testing, thereby leaving some bugs behind, which later meddle with the smooth working of the program. While some companies have specific software testing groups, some do not. In order to maintain a good product quality, software quality assurance is a very important step in the product development. Big business companies have given much thought to the entire issue, and come up with a solution to deal with the deadline pressure, as well as ensure product testing. Software testing is nowadays outsourced to offshore Quality Assurance agencies, so that the process of product development is quickened. One may ask why the developer himself can’t test carry out the quality assurance testing, as he would be the person to know every minute detail of the software. It is true that the developer is the person with the maximum knowledge about the product; however, it should be noted that software development takes place in parts, and then the different parts are assembled together to come up with the final product. During the assembling, minor errors might occur which can be overlooked by the developer. Moreover, due to an abundance of Quality Assurance firms, outsourcing software testing makes product development faster. It should be noted that the entire purpose of software testing is not just the location of bugs. Software quality assurance testing also involves confirmatory tests and performance. After the test runs, the bugs are sometimes sent back to the developers for re-programming, and sometimes they are modified by the Quality Assurance team. After modification, the testers again check for bugs and the process repeats until the software is completely bug free. Software testing can be carried on in two different modes. One is the manual software testing, and the other is the automated software testing. The manual mode is a time consuming mode, and hence most companies nowadays prefer the automated mode. With a thorough check on location and removal of bugs, and assurance on the flawless running of a program, a product can achieve maximum customer satisfaction. The automated software testing is carried out with the help of a number of software testing tools which are developed by the Quality Assurance firms. With time, as the demand for software is increasing, consequently the demand for these automated software testing tools is also increasing. It is an effective way to software validation, and it saves a lot of time. While some companies outsource their application testing task to other companies, some companies prefer to keep their software to themselves. In cases like this, they prefer buying these automated software testing tools from Quality Assurance companies and run them with the help of their own group of software testers.
