Blank Rows in CSV Data

Will a blank rows/row in a CSV file be picked up during execution?

Yes. Blank rows in a CSV file are treated as entries and are picked up during iteration execution.

If a CSV file contains a blank row, Appvance IQ will include that row as an iteration. Any corresponding fields with blank values will be pickedprocessed as empty values.

For example, if the CSV contains:

username,password
user1,password1
,
user3,password3

The blank row will still be processed as an entryiteration.
