| <div class="block">This interface defines the interactions between the JavaSampler and external |
| Java programs which can be executed by JMeter. Any Java class which wants to |
| be executed as a JMeter test must implement this interface (either directly |
| or indirectly through AbstractJavaSamplerClient). |
| <p> |
| JMeter will create one instance of a JavaSamplerClient implementation for |
| each user/thread in the test. Additional instances may be created for |
| internal use by JMeter (for example, to find out what parameters are |
| supported by the client). |
| <p> |
| When the test is started, setupTest() will be called on each thread's |
| JavaSamplerClient instance to initialize the client. Then runTest() will be |
| called for each iteration of the test. Finally, teardownTest() will be called |
| to allow the client to do any necessary clean-up. |
| <p> |
| The JMeter JavaSampler GUI allows a list of parameters to be defined for the |
| test. These are passed to the various test methods through the |
| <a href="JavaSamplerContext.html" title="class in org.apache.jmeter.protocol.java.sampler"><code>JavaSamplerContext</code></a>. A list of default parameters can be defined |
| through the getDefaultParameters() method. These parameters and any default |
| values associated with them will be shown in the GUI. Users can add other |
| parameters as well. |
| <p> |
| When possible, Java tests should extend <a href="AbstractJavaSamplerClient.html" title="class in org.apache.jmeter.protocol.java.sampler"><code>AbstractJavaSamplerClient</code></a> rather than implementing JavaSamplerClient |
| directly. This should protect your tests from future changes to the |
| interface. While it may be necessary to make changes to the JavaSamplerClient |
| interface from time to time (therefore requiring changes to any |
| implementations of this interface), we intend to make this abstract class |
| provide reasonable default implementations of any new methods so that |
| subclasses do not necessarily need to be updated for new versions. |
| Implementing JavaSamplerClient directly will continue to be supported for |
| cases where extending this class is not possible (for example, when the |
| client class is already a subclass of some other class). |
| <p> |
| See <a href="../test/SleepTest.html" title="class in org.apache.jmeter.protocol.java.test"><code>SleepTest</code></a> for an example of |
| how to implement this interface.</div> |
