JMeter assertion for a API response which contains [] or string "transaction"

How can we assert an API response which contains [] or "transaction"?

Jmeter Assertion should pass if it contains any of the below response Response 1: [] (only empty square brackets) or Response 2: contains string "transaction" as part of response

Solution

  • The easiest is going for Response Assertion configured like:

    enter image description here

    It will pass in 2 cases:

    • when response body will contain []
    • or when response body will contain transaction

    if response body won't contain any of these - the assertion will fail.
