Easy way to automate testing

I continue explaning about LoadRunner iteration number.
Well, how to determine the current iteration number?

• The first way is to use LoadRunner parameter od 'Iteration Number' type.
  It is described here
• The second way is to use a LoadRunner global variable.
  I will explain this approach now. Also, you will see how to define and use global variables.
  
  

1. Define a global variable
   You can add a new variable definition into vuser_init section of LoadRunner script:
   
   
2. Then we will add a variable incrementation and usage into Action section of LoadRunner script. For example, like this:
   Please, note that LoadRunner does not require using of "extern" keyword.
   
   
3. And last step is to open LoadRunner Run-time Settings and to set the desired total iteration count. In my example I set it to 3:
   
   
4. That's all! Let's start our script and see Log-file:
   
   As you can see, nIterationNumber variable changes its values with every new iteration.
   
   Tip: do not forget to increment its value, for example with ++ operator.
   
   Both proposed approaches (with LoadRunner parameter and with a global variable) are simple enough. Use any you like and track your LoadRunner iterations thoroughly :)
