For a long time testing has been considered secondary in the entire system development life cycle but nowadays it is being considered as a critical thing in the entire cycle. This is something which is picking up throughout the world. Companies throughout the world are focusing one test phase as there have been several fatal cases or cost of a project shooting up significantly and major embarrassment to the company which did the development work because they were inefficient in detecting the bugs which creep up later causing significant business loss to the client.
Earlier there were no investments done in the test phase in terms of estimate it was not even counted while bidding or allocating projects. But nowadays focus has shifted in recruiting full time personnel for this purpose, causing a great source of employment for people who are interested in working in this domain and developing expertise on it, adding skill sets which provide them advantage both locally as well as globally. A lot of students Freshers especially are gaining a lot because they are getting jobs into this sector right out of campus into multinational companies which otherwise would have been very difficult to do.
It's one of the most growing sectors in the software sector creating a huge demand for personnel who have skills in automated and manual methods of working. The entire sector has been progressing at a rate of more than 21%, making it one of the most lucrative sectors to work for. Quality Assurance is being taken seriously across the board in all companies. Nowadays a lot of companies based in the west have sent their jobs to companies based in the third world increasingly to reduce their costs. Testing is considered to be both destructive as well as constructive. Destructive as it helps in finding bugs in the software and constructive as it helps preventing errors coming/creping up in the first place.
Companies are now realizing that the testing phase is critical to their clients overall strategy in providing solution to the end user. Researchers while performing analysis of software projects found out that the prominent reason for the projects getting scrapped or terminated.
There are various methodologies as part of software test based technology. Quality Assurance can mean different things to different based working in different industry domains. For example in manufacturing industry ISO standard is mostly used to denote the processes being followed in the sector whereas in Software services sector it is done in a comprehensive manner by experts who have extensive knowledge in this sector. When we talk about this term the terms which usually come our mind are reliability, stability, portability, maintainability, usability, user friendly, bug free.
The two kinds of methodologies which are extensively used are static and dynamic methodologies. The destructive nature requires that the personnel involved in s/w development should not make any assumption which were previously done by developer while creating the code.
Manual based test methodology has been in the limelight for a very long time. It is an approach where the tester writes all the test cases himself/herself and executes the same. It is a tedious process where a lot of man ours or man days are spent on the project trying to work on the project. Earlier this approach was being used by most of the companies as no methods of automated based approach had been present, but since he advent of automated approach the task of testers has become a lot easier. There are several builds of code in a project which is evaluated by the test team. Each build needs approval from the team before it is released into the production environment. Any software product or a piece of software before being released into the end user environment is thoroughly checked that it meets the business and technical requirements of the client. Nowadays with the advent of automated tools like a Quick Test Professional and other automated techniques based on regression approach it has become a lot easier for testers to perform multiple regression tests for code which has been evaluated once to make sure that any new errors have crept in the system.
These kind of tools is being used commonly among all the professionals and has made the life easier for testers. Another reason is that with so many technological changes taking place in day to day life newer kinds of tools are coming up which are providing a competitive edge to a company which are using those as compared to other companies which are not using them. These tools have also reduced the overall time allocated for this phase and helping the products to become bug free and less error prone. There are several advantages in using these techniques the primary being that human error can be removed. In most cases it has been found that human error being the cause of applications crashing. Another thing is that these tools can be used to maintain the system reliability. Software testing services shall drive revenues for companies depending on this sector.
