I am new to Jmeter. I need to write an assertion to my http request. The HTTP request returns all the tags available as an array in JSON response and I need to assert that my tag, which I have stored as a variable, is part of the response
I have tried using ${tagName}
as well as vars.get("tagName")
for response assertion, but both are doing the string match rather than matching the variable value.I am sure there is an easy fix to this. Please help.
In case of "normal" Response Assertion as per How to Use JMeter Assertions in Three Easy Steps article:
The most commonly used assertion is the Response Assertion, which checks whether a response text/body/code/message/header contains, matches, or equals a specified pattern.
The Pattern can be either be:
- a “string” for “Equals” or “Substring” clauses
- a “Perl5-style” Regular Expression for “Contains” or “Matches” clauses
So the configuration you're looking for is "Substring" pattern matching rule and should be something like:
tagName variable doesn't have a value so double check the way you're creating/assigning it. You can see all JMeter Variables with their respective values using Debug Sampler and View Results Tree listener combination
Have you tried using the JSON Assertion item, rather than the Response Assertion?
You can then assert that the JSON path in the response exists and is set to a value, which can be a JMeter variable.
Your JSON path in it might be something like $.tagName (or whatever the field is called in the response) and the expected value might be ${tagName} (your variable).
