Class SleepTest
java.lang.Object
org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient
org.apache.jmeter.protocol.java.test.SleepTest
- All Implemented Interfaces:
Serializable
,JavaSamplerClient
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.

Method Details
-
setupTest
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 interfaceJavaSamplerClient
- Overrides:
setupTest
in classAbstractJavaSamplerClient
- Parameters:
context
- the context to run with. This provides access to initialization parameters.
-
runTest
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 aSampleResult
object.SampleResult
has many fields which can be used. At a minimum, the test should useSampleResult.sampleStart
andSampleResult.sampleEnd
to 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 interfaceJavaSamplerClient
- Parameters:
context
- the context to run with. This provides access to initialization parameters.- Returns:
- a SampleResult giving the results of this sample.

-
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 interfaceJavaSamplerClient
- Overrides:
getDefaultParameters
in classAbstractJavaSamplerClient
- 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.
