clear

public void clear()

Description copied from class: AbstractTestElement

Clear the TestElement of all data.

Specified by:

clear in interface TestElement

Overrides:

clear in class AbstractTestElement

testStarted

public void testStarted()

Description copied from interface: TestStateListener

Called just before the start of the test from the main engine thread. This is before the test elements are cloned. Note that not all the test variables will have been set up at this point.

N.B. testStarted() and testEnded() are called from different threads.

Specified by:

testStarted in interface TestStateListener

See Also:

StandardJMeterEngine.run()

testEnded

public void testEnded()

Description copied from interface: TestStateListener

Called once for all threads after the end of a test. This will use the same element instances as at the start of the test.

N.B. testStarted() and testEnded() are called from different threads.

Specified by:

testEnded in interface TestStateListener

See Also:

StandardJMeterEngine.stopTest()

testStarted

public void testStarted(String host)

Description copied from interface: TestStateListener

Called just before the start of the test from the main engine thread. This is before the test elements are cloned. Note that not all the test variables will have been set up at this point.

N.B. testStarted() and testEnded() are called from different threads.

Specified by:

testStarted in interface TestStateListener

Parameters:

host - name of host

See Also:

StandardJMeterEngine.run()

testEnded

public void testEnded(String host)

Description copied from interface: TestStateListener

Called once for all threads after the end of a test. This will use the same element instances as at the start of the test.

N.B. testStarted() and testEnded() are called from different threads.

Specified by:

testEnded in interface TestStateListener

Parameters:

host - name of host

See Also:

StandardJMeterEngine.stopTest()

testIterationStart

public void testIterationStart(LoopIterationEvent event)

Description copied from interface: TestIterationListener

Each time through a Thread Group's test script, an iteration event is fired for each thread. This will be after the test elements have been cloned, so in general the instance will not be the same as the ones the start/end methods call.

Specified by:

testIterationStart in interface TestIterationListener
