One stage of testing is Unit testing. In unit testing the user focuses on whether the unit meets the requirements stated in the program specifications. Unit testing is performed after the programmer has developed and tested the code. The primary goal is this unit testing may discover errors resulting from the programmer's misinterpretation of the specifications. There are two approaches to unit testing which are black-box and white-box. Black-box testing is the most common in which each item in the program specification becomes a test. White-box testing is for special circumstances where the tester wants to review the actual program code.
The second stage of testing is Integration testing. This stage evaluates whether a set of modules or programs that are required to work together do so without errors. They make sure that the interfaces and linkages between the different parts of the system work correctly. Focus is on flow of control and on data exchanges in the system. There are four approaches to integration testing which are user interface testing (tests each interface function), use scenario testing (tests each use scenario), data flow testing (tests each process in a step by step fashion), and system interface testing (tests the exchange of data with other systems). Almost every project uses all four approaches.
The third stage is system testing. They are conducted by the systems analysts ensuring everything is in proper working order in correspondence with the entire systems, including modules and programs. Additionally, system testing examines how well the system meets the requirements of the business and its overall usability, security and performance under heavy work loads. The documentation of the system is also tested during the system testing stage.
The fourth stage of testing is acceptance testing. THis type of testing is done primarily by the people who support the project and the team. The point of acceptance testing is to make sure that the system is finsihed or complete, that it will meet the business needs that first designated the design to be developed and that people who will use the system find it acceptable.
To go further with Justine's blog entry acceptance testing is done by users to determine whether the system is acceptable to them. It draws on the system test plans(alpha testing) and real work the users perform (beta testing).
Unit testing is where the programmer tests to ensure that the module is functioning as it should. The primary goal of unit testing is to check for any misinterpretations made by the programmer when setting up the system. This is the stage that we are currently in for our group projects; we have designed how we want the system to appear now it is time for the programmers to implement our requirements and then test to ensure no errors were made. There are two approaches to unit testing, the most popular approach is Black-box testing, this is where the test plan is developed from the program specification. The other approach to unit testing is White-box testing, this is really done because of its complexity. White-box testing is where the tester wants to review the actual code for the program.
To go off of Justi's and Robert's post, there are the two types of testing--Aplha and Beta. An example of Alpha testing would be tests done during training of a store's staff in the use of in store kiosks. Employees would work together to devop a series of tests and training exercises to train staff onhow to use the system.
Beta testing would begin by "going live" with in store kiosks. This is when the customers would have the chance to use and evaluate the system.
The four stages of testing are as follows: Unit tests, whose main goal is black-box testing. Integration tests, whose purpose is to ensure that the web interface and system management components encompass all user interface and use scenario tests. Systems tests, test the entire system based on security, performance and usability. Acceptance tests, are conducted in two stages alpha and beta. Alpha is done during the training of staff and beta is when "going live".
One stage of testing are system tests that are conducted by system analysts that make sure that the systems and programs work together without error. They also make sure that the business requirements are met, and it's usability and security are where they need to be.
