Debugging a CorDapp
|
||
|
|
===================
|
||
|
|

|
There are several ways to debug your CorDapp.
|
||
|
|
|
||
|
|
Using a ``MockNetwork``
|
||
|
|
-----------------------
|
||
|
|
|
||
|
|
You can attach the `IntelliJ IDEA debugger <https://www.jetbrains.com/help/idea/debugging-code.html>`_ to a
|
||
|
|
``MockNetwork`` to debug your CorDapp:
|
||
|
|
|
||
|
|
* Define your flow tests as per :doc:`api-testing`
|
||
|
|
|
||
|
|
* In your ``MockNetwork``, ensure that ``threadPerNode`` is set to ``false``
|
||
|
|
|
||
|
|
* Set your breakpoints
|
||
|
|
* Run the flow tests using the debugger. When the tests hit a breakpoint, execution will pause
|
||
|
|
|
||
|
|
Using the node driver
|
||
|
|
---------------------
|
||
|
|
|
||
|
|
You can also attach the `IntelliJ IDEA debugger <https://www.jetbrains.com/help/idea/debugging-code.html>`_ to nodes
|
||
|
|
running via the node driver to debug your CorDapp.
|
||
|
|
|
||
|
|
With the nodes in-process
|
||
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^
|
||
|
|
|
||
|
|
1. Define a network using the node driver as per :doc:`tutorial-integration-testing`
|
||
|
|
|
||
|
|
* In your ``DriverParameters``, ensure that ``startNodesInProcess`` is set to ``true``
|
||
|
|
|
||
|
|
2. Run the driver using the debugger
|
||
|
|
|
||
|
|
3. Set your breakpoints
|
||
|
|
|
||
|
|
4. Interact with your nodes. When execution hits a breakpoint, execution will pause
|
||
|
|
|
||
|
|
* The nodes' webservers always run in a separate process, and cannot be attached to by the debugger
|
||
|
|
|
||
|
|
With remote debugging
|
||
|
|
^^^^^^^^^^^^^^^^^^^^^
|
||
|
|
|
||
|
|
1. Define a network using the node driver as per :doc:`tutorial-integration-testing`
|
||
|
|
|
||
|
|
* In your ``DriverParameters``, ensure that ``startNodesInProcess`` is set to ``false`` and ``isDebug`` is set to
|
||
|
|
``true``
|
||
|
|
|
||
|
|
2. Run the driver. The remote debug ports for each node will be automatically generated and printed to the terminal.
|
||
|
|
For example:
|
||
|
|
|
||
|
|
.. sourcecode:: none
|
||
|
|
|
||
|
|
[INFO ] 11:39:55,471 [driver-pool-thread-0] (DriverDSLImpl.kt:814) internal.DriverDSLImpl.startOutOfProcessNode -
|
||
|
|
Starting out-of-process Node PartyA, debug port is 5008, jolokia monitoring port is not enabled {}
|
||
|
|
|
||
|
|
3. Attach the debugger to the node of interest on its debug port:
|
||
|
|
|
||
|
|
* In IntelliJ IDEA, create a new run/debug configuration of type ``Remote``
|
||
|
|
* Set the run/debug configuration's ``Port`` to the debug port
|
||
|
|
* Start the run/debug configuration in debug mode
|
||
|
|
|
||
|
|
4. Set your breakpoints
|
||
|
|
|
||
|
|
5. Interact with your node. When execution hits a breakpoint, execution will pause
|
||
|
|
|
||
|
|
* The nodes' webservers always run in a separate process, and cannot be attached to by the debugger
|
||
|
|
|
||
|
|
