JMeter Assertion failure with groovy - json

Question

Update:
I want to check a JSON document on his structure. I created a JSR223 Assertion with language groovy. My code to check the JSON structure looks like this:
import groovy.json.*;
import org.apache.jmeter.samplers;
def response = prev.getResponseDataAsString();
log.info("Response" + response);
def json = new JsonSlurper().parseText(response);
//tests
def query = json.query;
assert query instanceof String;
def totalResults = json.totalResults;
assert query instanceof Integer;
def from = json.from;
assert from instanceof Integer;
def to = json.to;
assert to instanceof Integer;
assertionResult = new AssertionResult("Assertion failed! See log file.");
assertionResult.setError(true);
assertionResult.setFailureMessage(e.toString());
The validation in the JMeter logfile works great.
But in my View Result Tree, i got the following error message:
Assertion error: true
Assertion failure: false
Assertion failure message: javax.script.ScriptException: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Script27.groovy: 2: unable to resolve class org.apache.jmeter.samplers
# line 2, column 1.
import org.apache.jmeter.samplers;
^
Script27.groovy: 21: unable to resolve class AssertionResult
# line 21, column 19.
assertionResult = new AssertionResult("Assertion failed! See log file.");
^
2 errors
I want to see if the test result is successful or not.
How to fix this issue?

Answer 1

Don't instantiate AssertionResult class, it is pre-defined
Don't use Groovy assert keyword, it won't fail the parent sampler as expected, refer below example simple code
if (1 != 2) {
AssertionResult.setFailure(true)
AssertionResult.setFailureMessage("1 is not equal to 2")
}
once you get it working like below:
you can start modifying your tests as required
