Software Functional Testing Is Done At Various Levels.

Software functional testing is done at different levels to identify bugs and eliminate them. Software development has become more complicated than ever because of the awareness of the customer about various facilities available in a particular programming platform. To meet the entire customer requirement and satisfy the customer is more important in the competitive world because alternatives and substitutes available to the customer are more as the world is becoming a global village. Those software testing companies which give due importance to the software testing phase can only withstand the market. 

Software functional testing services is done to check various functions of the software like durability, execution, load handling when data storage is more and different types of user handling and data security. Each of the above mentioned functions of the software has to be tested with a team of software testers. The job can be done by the same development company by having a separate team of software testers or the job can be outsourced to companies. There are many companies which are specialized in many form of software testing like test automation services and manual software testing.

Software functional testing involves different methods. There are auto testing tools which test the basic errors and automatically solve the common bugs. Manual testing is also done to ensure the quality of the software. Load runner, win runner are the common testing tools available in the market. There are also software testing tools which are specialized to test a particular functionality of software. The durability of the software has to be tested. This becomes essential because the investment on software is very costly and if a project fails, the organization incurs a loss on their investment and the efforts taken to develop and implement a project will also go waste.

The next functionality that has to be tested is the load accepting. It tests the strength of the database. The database has to be very strong to manage a large volume of data. To test this efficient design for the database has to be developed and tested to ensure the strength of the database.  With all these testing methods emerging to test various functionalities, Software testing has become a separate career line. The opportunities are growing equivalent to the software programming. It attracts young people who have an eye for detail and solve all the bugs without leaving any. In the actual scenario we find that it is not possible to remove 100% of all the bugs. Bugs exist in spite of testing so effectively. The point is that it should not affect the performance of the software drastically and prevent the customer from using the software package..

The common methods to test the software functions are closed and the open method. The closed method is otherwise called as grey box testing and open method is otherwise known as white box testing.
