What do you mean by Data flow testing?

Answer»

Data flow testing is a type of STRUCTURAL testing that is used to analyze the flow of data in the program. In this, a programmer can perform various tests on data values and variables. USING this testing, one can determine the variables that are used at every stage of the program’s control flow. It HELPS us in the following ways: 

  • Eliminate or remove variables that are NEVER used after being declared  
  • Pinpoint variables that are used but never declared  
  • Deallocate variable before it is used 
  • Pinpoint variables that are DEFINED multiple times before it is used
