Hi Rajeswari,
Ensure Property Matches Expression: This gives you freedom of applying assertion on any LISA property(default or user created you want.
While,
Ensure Result Contains Expression: This by default applies on {{stepname.rsp}} property of step.
Function for both are same to look-up for Expression provided.
For your second question:
1- If you looking for fixed value in response, use Regular expression: " XSAMN920TB32 |
610214653208 "
2- If you need to look for regular expression, use:" [expressionforfirstvalue] | [expressionforsecondvalue] ".
Please check if this helps.
Thanks,
Dinesh Kumar
