Adding Response Assertion to a Java Sampler
Hi,
I am trying to load test a Java application and would like to verify some
results by applying a response assertion on the returned value.
The code looks something liek this:
....
SampleResult results = new SampleResult();
try {
results.sampleStart();
String response = getResponseFromJavaApp();
results.setSamplerData("\\[testCount 1\\]"); // what does this
method do?
ResponseAssertion assertion = new ResponseAssertion();
assertion.setAssumeSuccess(false);
assertion.setName("Assertion Results");
assertion.setTestField(response);
AssertionResult result = assertion.getResult(results);
logger.debug("Failure message = " + result.getFailureMessage());
AssertionResult[] ars =results.getAssertionResults();
results.setSampleLabel(response);
....
I would like to know if my response contains the required text....how do I
verify this? What is it that I am doing wrong in the code above/
Any tips would be appreciated .
Thanks
M

The external system is the system under test - e.g. for HTTP sampler
it is the http server.
The data is used by the Listeners. You can put whatever you like in
the field, but unless it corresponds (in some way) with the data the
sampler "sends" to the "external system" it won't be much use.

If you code the sampler correctly, response Assertions will do this for you

Listeners can already save failed samples.

Please have a look at the example code, and try running some test
plans with Assertions and Listeners.

Thanks, that makes a lot of sense now :)
"It sets the sampler data - i.e. the data that the sampler passed to
the external system."
What do you mean by the external system? Where exactly can I use this
sampler data?
Also is there anyway to create a "batch process" wherein
1) I call the method A with some input parameter (do-able)
2) get the response from method B (do-able)
3) get the Patterns to Test from Response Assertion for a particular input
parameter -- -- not sure how??? (of course, there should be 1-1 mapping
between the input parameter and the pattern & this should be hard-coded
somewhere)
4) and if the test fails, dump the output to a file (I think this step easy)
This way I can load-test and also verify if the expected & observed results
match.
Cheers

OK - you also need a sampleEnd();

It sets the sampler data - i.e. the data that the sampler passed to
the external system.
It should be set before running the sample.

Assertions are added as separate test elements, not as code in the sampler.

Add an assertion in the test plan.
Or just use standard Java code.

Have a look at some of the example samplers under src/examples.
