Data Flow Testing

Finally, for this week I decided to write about Data Flow Testing. I found a blog site called Ques10 and there was a question about what is data flow testing. The blogger Ramnarth ansered the question by explaining what Data Flow Testing is. Data Flow Testing is a test that tells us that a programmer can perform a number of test on data values which are collectively known as data flow testing. With data flow testing it can be performed at two levels static and dynamic. Static testing is performed by analyzing the source code and doesn’t involve in running the source code. It is performed to reveal potential problems in the programs which are also known as a data flow anomaly.  And with dynamic testing it looks at the path of the program from the source code and with this you would draw a data flow graph of the program select a critical testing area, then identify the paths in that data flow and test the derive inputs. He talks about how testing critical section on the data flow chart by breaking it down into paths and tests such as how we did it in class. Were we would look at the DU-Paths and look at all the edges and nodes to see if they make sense. I like this blog because it does involve some of the things that we did in class such as DU-Path testing, edges, and node testing. I like that the things I learned in class is also reflected into real life things we can do. I think data flow testing is just something we could be doing because it is just a bunch of tests that you run through so that way you do multiple test at the same time.
