The Growth of Application Testing and Development Services

It is commonly believed that the earlier a defect is found the cheaper it is to fix it. Any software product before it is launched has to undergo endless rounds of testing. Application testing is essentially an investigation conducted to inform its stakeholders about the quality of the product or service under test with respect to the relevant context. It could also aid the process of executing a program with the intent of finding software bugs.

A primary purpose for testing is to detect software failures so that defects may be uncovered and corrected. This is a non-trivial pursuit. Testing cannot establish that a product functions properly under all conditions but can only establish that it does not function properly under specific conditions. The scope often includes examination of code as well as execution of that code in various environments and conditions as well as examining the quality aspects of code: does it do what it is supposed to do and do what it needs to do. In the current culture of application development services, a testing organization may be separate from the development team. There are various roles for testing team members. Information derived from software testing may be used to correct the process by which software is developed.

There are many approaches to application testing. Reviews, walkthroughs or inspections are considered as static testing, whereas actually executing programmed code with a given set of test cases is referred to as dynamic testing. More than often the former is omitted, whereas the latter takes place when programs begin to be used for the first time – which is normally, considered the beginning of the testing stage. This may actually begin before the program is 100{70c334fb92e874d1e6848b98072ad90d8e1e4d18d72219bf8863dcf279bcb8a9} complete in order to test particular sections of code (modules or discrete functions). For example, Spreadsheet programs are, by their very nature, tested to a large extent “on the fly” during the build process as the result of some calculation or text manipulation is shown interactively immediately after each formula is entered. Several certification programs exist to support the professional aspirations of software testers and quality assurance specialists. No certification currently offered actually requires the applicant to demonstrate the ability to test software. No certification is based on a widely accepted body of knowledge. Many IT giants have their in-house testing department.
