Alpha and Beta Testing-Acceptance Testing

            Alpha and Beta Testing

Acceptance Testing
  • Making sure the software works correctly for intended user in his or her normal work environment.
  • Alpha test (version of the complete software is tested by customer under the supervision of the developer at the developer’s site)
  • Beta test (version of the complete software is tested by customer at his or her own site without the developer being present)
  • Software can be built as a custom software, (e.g. MIS for a particular organization) for one customer or as a product to be used by many customers.
  • When it is developed as custom software, a series of acceptance tests are conducted to enable the customer to validate all requirements.
  • They are conducted by the end-user rather than software engineers and may be conducted over a period of weeks or months.
  • In case of software being developed as a product it is not possible to have acceptance testing by each end-user and hence a process called alpha and beta testing is followed.
  • The alpha test is conducted by a customer at the developer’s site.
  • The developer records errors and usage problems.
  • They are conducted in controlled environment.
  • The beta test is conducted at one or more customer sites by the end-user of the software.
  • The developer is generally not present.
  • The customer records all problems and reports to the developer at regular intervals.
  • Based on these reports the developer modifies the software and then releases to the entire customer base.

What is DFD ? or What is Data Flow Diagram?

A data-flow diagram ( DFD ) is a graphical representation of the "flow" of data through an information system. DFDs can also be used for the visualization of data processing ( structured design ). On a DFD , data items flow from an external data source or an internal data store to an internal data store or an external data sink, via an internal process . A DFD provides no information about the timing or ordering of processes, or about whether processes will operate in sequence or in parallel. It is therefore quite different from a flowchart, which shows the flow of control through an algorithm, allowing a reader to determine what operations will be performed, in what order, and under what circumstances, but not what kinds of data will be input to and output from the system, nor where the data will come from and go to, nor where the data will be stored (all of which are shown on a DFD ). ...

Rules for Stopping the Decomposition Process in DFD

Rules for Stopping the Decomposition Process in DFD (1) when you have reduced each process to a single decision or calculation or to a single database operation;  (2) when each data store represents data about a single entity;  (3) when the system user does not care to see any more detail or when you and other analysts have documented sufficient detail to do subsequent systems development tasks;  (4) when every data flow does not need to be split further to show that different data are handled in different ways;  (5) when you believe that you have shown each business form or transaction, computer on-line display, and report as a single data flow;  (6) when you believe there is a separate process for each choice on all lowest-level menu options for the system.
