Class SleepTest

java.lang.Object
org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient
org.apache.jmeter.protocol.java.test.SleepTest
All Implemented Interfaces:
Serializable, JavaSamplerClient, Interruptible
@AutoService(JavaSamplerClient.class) public class SleepTest extends AbstractJavaSamplerClient implements Serializable, Interruptible
The SleepTest class is a simple example class for a JMeter Java protocol client. The class implements the JavaSamplerClient interface.

During each sample, this client will sleep for some amount of time. The amount of time to sleep is determined from the two parameters SleepTime and SleepMask using the formula: 

 totalSleepTime = SleepTime + (System.currentTimeMillis() % SleepMask)
Thus, the SleepMask provides a way to add a random component to the sleep time.

    • SleepTest

      public SleepTest()
      Default constructor for SleepTest. The Java Sampler uses the default constructor to instantiate an instance of the client class.

  • Method Details

    • setupTest

      public void setupTest(JavaSamplerContext context)
      Do any initialization required by this client. In this case, initialization consists of getting the values of the SleepTime and SleepMask parameters. It is generally recommended to do any initialization such as getting parameter values in the setupTest method rather than the runTest method in order to add as little overhead as possible to the test.
      Specified by:
      setupTest in interface JavaSamplerClient
      Overrides:
      setupTest in class AbstractJavaSamplerClient
      Parameters:
      context - the context to run with. This provides access to initialization parameters.

    • runTest

      public SampleResult runTest(JavaSamplerContext context)
      Perform a single sample. In this case, this method will simply sleep for some amount of time. Perform a single sample for each iteration. This method returns a SampleResult object. SampleResult has many fields which can be used. At a minimum, the test should use SampleResult.sampleStart and SampleResult.sampleEndto set the time that the test required to execute. It is also a good idea to set the sampleLabel and the successful flag.
      Specified by:
      runTest in interface JavaSamplerClient
      Parameters:
      context - the context to run with. This provides access to initialization parameters.
      Returns:
      a SampleResult giving the results of this sample.

    • getDefaultParameters

      public Arguments getDefaultParameters()
      Provide a list of parameters which this test supports. Any parameter names and associated values returned by this method will appear in the GUI by default so the user doesn't have to remember the exact names. The user can add other parameters which are not listed here. If this method returns null then no parameters will be listed. If the value for some parameter is null then that parameter will be listed in the GUI with an empty value.
      Specified by:
      getDefaultParameters in interface JavaSamplerClient
      Overrides:
      getDefaultParameters in class AbstractJavaSamplerClient
      Returns:
      a specification of the parameters used by this test which should be listed in the GUI, or null if no parameters should be listed.

    • interrupt

      public boolean interrupt()
      Description copied from interface: Interruptible
      Interrupt the current operation if possible.
      Specified by:
      interrupt in interface Interruptible
      Returns:
      true if there was an operation to interrupt.
