A common problem in JMeter is that you want a CSV file as an input and want to execute each line, then continue. So from a script perspective that would look something like this:
Thread Group |-For Each CSV Line | |-HTTP Request (CSV input) |-Do something else
The issue though is there is no “For Each” concept in JMeter. I know that it is called a ForEach Loop in JMeter but it isn’t from a developer view. You need to know the length of your CSV file. You could just tell the For loop how many lines there are but that would make it very unflexible. You’d need to adjust the script every time the CSV changes.
So here is how I solved it. Not elegant but it actually works quite well.
