Good morning everybody, Thank you for your involvement in JMeter and reading this message.
I am starting this thread to gather insight on (technical) possibilities for embedding JMeter in another program / for running JMeter scripts from other Java code. Chris Widhelm started a similar thread in 2004, but that stranded in some debate on 'why one would want to do such' and the suggestion to use httpunit instead of JMeter. == why I want JMeter and not some other library == I work for a company that created a client-server application in which the client communicates to the server via a proprietary and rather complicated web of http messages. Simple record and playback on this interface gave challenges because of propriety cryptographic key exchange and dynamic values originating from the server that must be included in successive calls to the server. Somebody in this company created a JMeter plug-in that handles this stuff, allowing us to record sessions between client and server and play it back. The plug-in is black-box for me and the guy who developed it is, off course, long gone. I want to use JMeter for automated testing of the server side of our application because of this plug-in and the good editor for recording new scripts. In this automated testing I would like to run jmx scripts as part of something bigger and I would like to call it from Java. Since JMeter is written in Java I figured this would be possible. == what I have found so far == What I find most is that people install JMeter in a fixed location and call it via the command line. That is for example what the JMeter ant task does: * http://www.programmerplanet.org/pages/projects/jmeter-ant-task.php To my knowledge there is one solution that attempts to do it all 'the Java way' (jars on class path and calling methods), which is the maven-jmeter-plugin (for more information on that see): * http://www.ronniealleva.org/index.php/maven-jmeter-plugin/ * https://github.com/Ronnie76er/jmeter-maven-plugin/blob/master/src/main/java/org/apache/jmeter/JMeterMojo.java As you might see in the last link: there is quite some code involved to put property files where JMeter expects them and pass configuration in a commandline-ish way. Of course I could go and re-factor this jmeter-maven-plugin into some sort of JMeter API, but I am afraid that it will turn out to be a rabbit hole, because I am not too familiar with the detailed working of JMeter (I can do some basic stuff via the editor, but that I as far as I got so far). Also this jmeter-maven-plugin has been developed specifically for 2.3.2 and I am afraid that it might become out-dated easily. == my questions == Basically my question(s) are quite open to start with: * does anyone have experiences with running JMeter embedded in another Java program? * do you guys think it is feasible to create a pure Java API to make this easier? * do you guys think such API should be part of the standard JMeter product (separating engine and editor)? * or does such API maybe already exist? Thank you for reading this and many thanks in advance for any insight you can give me on this topic.
