How to use Jmeter Xpath extractor for multiple run in dynamic API elements

Question

XPath extractor response assertion passed first run but in second run it is getting failed because <name>pc</name> is not coming in API. How to skip this element if it is not coming in second run without failing response assertion or any suggestions for this?

API response first run:

API response in second run: missing element < name > pc < /name >

Response assertion - DB values(name_1)using jdbc request match with xml element(name) in API response

Answer 1

You have two ways:

• either you add an If Controller checking the content of the name in the response (clause be like ${__groovy( ${name}?.trim() )} ) and put inside there the assertion, so to avoid asserting if the name is empti

• or you try to make it pass even if the name is empty: you need to figure out why the API is returning an empty name; in that case your comparing value (expected value) should be empty as well; you cannot have the test pass if an expected information is not returned

Answer 2

I would suggest you to use /part01[position()<2] as a value of XPath query. I think it will solve your problem.

Answer 3

use JSR223 Assertion for assertion. So, you'll have better control over it.

String responseData = vars.get("name");
