I received the following response

Mink

Provide more details like what is the json path you've written? what is the expected value in your example? – Markup

Please check the below images,my test plan & and its response – Mink

Did you try to remove square brackets? – Frogman

Change [200] to 200 in Expected value. – Markup

Removing square brackets works,but how should I will know the JSON path assertion got passed ? – Mink

@Mink You won't be getting error like the one in your last screenshot. – Markup

Thank you guys it worked and I understood the concept – Mink

Answer 1

For start following JSONPath Assertion will test your statusCode

$.statusCode

put 200 to Expected Value of JSONPath Assertion.

This one is for userName

$.responseData.userName

Easy, isn't it? See Parsing JSON guide for more useful examples and how-tos.

Please check the below images,my test plan & and its response – Mink

Add your JSONPath assertion as a child of your HTTP Request and remove brackets around 200 – Immigration

Answer 2

I found the JSR223 Assertion with script language javascript to be the easiest. at least if you have knowledge in java and javascript. And no need to add any plugins.

My working code in detail:

var json = JSON.parse(SampleResult.getResponseDataAsString());
if (json.statusCode != 200) {
    AssertionResult.setFailureMessage("" 
        + json.statusCode 
        + " " + json.statusMessage
        + " " + json.errorMessage);
    AssertionResult.setFailure(true);
}

I used your code, but getting assertion failure: Assertion failure message:javax.script.ScriptException: groovy.lang.MissingPropertyException: No such property: JSON for class: Script1 – Lianna

Answer 3

I personally prefer to use BSF PostProcessor in coupling with Groovy language. Example of how to parse JSON with Groovy you can find here how to parse json using groovy

Frogman

Hi thank you for responding me,I'm new to Jmeter and im not that comfortable with Post Processor could you share step by step how to check the assertion for json data – Mink

Hi, I will be happy to help you but can you please show what you have tried so far? – Frogman

Please check the above images,my test plan & and its response – Mink

Why do you edit my answer?? Are you sure you wanted to answer me but not @Dmitriy T? – Frogman

Reverted to the original post, why don't you update your question, @Sreenivas? – Kimkimball

@Dmitriy T - sorry for editing ur answer .@Kimkimball I have posted my test plan and response. I need correct JSON path and expected value based on the above JSON data – Mink
