How to capture response of a Bean shell sampler

Question

Above is my code i have written to hit a web service whose endpoint is expecting a Byte Stream object. I am able to do that but i am not getting any response. I have to test the response. Though i am getting 200 ok but a string is sent in response that i am not getting.

And the response is blank

How can I get the response ?

Answer 1

You can add your output by using the SampleResult object:

String output = "...";

SampleResult.setResponseData( output );
SampleResult.setDataType( org.apache.jmeter.samplers.SampleResult.TEXT );

Answer 2

1. In order to read server's response you need to use URLConnection.getInputStream() method , not OutputStream
2. In order to convert stream to string you can use IOUtils.toString() method
3. In order to return data you can use return keyword

4. Minimal working code is below, adjust as per your needs:

    import java.net.HttpURLConnection; import java.net.URL; import java.nio.charset.StandardCharsets; import org.apache.commons.io.IOUtils; URL url = new URL("http://example.com"); HttpURLConnection con = (HttpURLConnection) url.openConnection(); con.setRequestMethod("GET"); String response = IOUtils.toString(con.getInputStream(), StandardCharsets.UTF_8); return response;

• Be aware of fact that JMeter is built on top of Apache HttpComponents so you can use the power of these libraries in order to create HTTP requests, see QuickStart wiki page to get ramped up in minutes
• Be aware that starting from JMeter 3.1 it is recommended to use JSR223 Test Elements and Groovy language for scripting , check out Apache Groovy - Why and How You Should Use It for comprehensive explanation, benchmarks, code samples, etc.
