In what order Listeners are executed in JMeter?

Listeners of all types are executed in the order described in the rules below:

1. If a Listener is attached to a Sampler, it is executed after all Assertions of the Sampler.
2. If a Listener is attached to a container (Test Plan, Thread Group, or Logical Controller), it is executed after Assertions to each every Samplers in that container tree branch.
3. If a Sampler has multiple Listeners inherited from multiple level of parent nodes, Listeners from a near parent are executed first.
4. If a Sampler has multiple Listeners inherited from parent nodes and attached as child leaves, Listeners attached as child leaves are executed first.
5. Multiple Listeners attached to the same parent node are executed sequentially.

Let's create the following Test Plan tree, JMeter-Execution-Order-6.jmx, to verify these rules:

Test Plan
   |- setUp Thread Group
   |     |- Sampler Z
   |- tearDown Thread Group
   |     |- Sampler A
   |- Thread Group 1
   |     |- Sampler 11
   |     |- Sampler 12
   |     |- If Controller (1==2)
   |           |- Sampler 13
   |- Thread Group 2
   |     |- PreProcessor 2
   |     |- PostProcessor B
   |     |- Listener J
   |     |- Assertion BB
   |     |- Sampler 21
   |     |- Sampler 22
   |     |- If Controller (2==2)
   |           |- Sampler 23
   |                 |- Assertion CC
   |                 |- Listener K
   |                 |- PostProcessor C
   |                 |- PreProcessor 3
   |- PreProcessor 1
   |- PostProcessor A
   |- Listener I
   |- Assertion AA

Run the above Test Plan. You see the following execution order:

PreProcessor 1
Sampler A
PostProcessor A
Assertion AA
Listener I      - Rule 2 applied

PreProcessor 1
Sampler 11
PostProcessor A
Assertion AA
Listener I      - Rule 2 applied

PreProcessor 1
Sampler 12
PostProcessor A
Assertion AA
Listener I      - Rule 2 applied

PreProcessor 2
PreProcessor 1
Sampler 21
PostProcessor B
PostProcessor A
Assertion BB
Assertion AA
Listener J      - Rule 3 applied
Listener I

PreProcessor 3
Sampler 23
PostProcessor B

Listener K      - Rule 4 applied
