In one of my tests I need to check that the data in an array matches to an expected result. I send an API call and receive the following JSON response:
{
"sting": "value",
"another string": "value",
"array": ["value1","value2","value3"]
}
Using the JSON Path Assertion plugin I'm able to check each value individually.
$.array[0]
Is there a way to evaluate all the array's values in one assertion?
Looking into Can't check an array with JSONPath Assertion. Update JSONPath to 2.1? currently it is not possible.
You can work it around using Response Assertion instead as follows:
Add JSON Path Extractor as a child of the request which returns above JSON and configure it as follows:
array $.arrayAdd Response Assertion after the JSON Path Extractor and configure it as follows:
arrayEqualsPatterns to Test: ["value1","value2","value3"] - make sure there are no trailing spaces, new lines, etc.

If your response may vary, i.e. array members order changes, you might need to consider scripting-based assertion, i.e. JSR223 Assertion instead
See How to Use JMeter Assertions in Three Easy Steps guide for comprehensive information on using JMeter Assertions in your tests.
I was able to get this to work by using the .. syntax. In your case, it would be $..array which would return
[
"value1",
"value2",
"value3"
]
Then you could, for example, check the "additionally assert value" box and "match as regular expression" and then do \w+ as the expected value, asserting that there is a word there.
