We can use Regular expression where ever there is
need of some conditional checkpoint, like if there is a condition that to check
that order number should start with 1.
We can put a standard checkpoint and use the regular
expression in standard checkpoint, while editing the standard checkpoint, we
see a “Regular Expression” button next to the value of Constant/Parameterization.
Click on this button, “Constant value option” window
will open.
Check the check box at the left side of “Regular
Expression”
To put condition for any value after first digit as 1
use “1. *”
It will check for any
value starting with 1.
