The ResourceSync Simulator simulates a ResourceSync Source, which is a server that hosts resources subject to synchronization.
Any ResourceSync-compliant client can be used to synchronize a Destination with the simulated Source. The simulator is tested with v0.6.2 of our own ResourceSync client and library reference implementationn.
Make sure Python 2.7.2 or later is running on your system:
sudo easy_install tornado
...and the ResourceSync simulator uses the ResourceSync client and library, which is currently available only from github (not yet on pypi). So manual download and install is required from Github:
cd /tmp git clone git://github.com/resync/resync.git cd resync/ python setup.py build sudo python setup.py install
Get the ResourceSync Simulator from Github:
git clone git://github.com/resync/simulator.git
Run the source simulator (with the default configuration in ./config/default.yaml):
chmod u+x simulate-source ./simulate-source
Terminate the source simulator:
How to define parameterized use cases
Parameterized Use Cases can be defined by creating a YAML configuration file (e.g., simulation1.yaml) and defining a set of parameters:
source: name: ResourceSync Simulator number_of_resources: 1000 change_delay: 2 event_types: [create, update, delete] average_payload: 1000 max_events: -1 stats_interval: 10
Additional resource_list_builder and change memory implementations can be attached for simulation purposes. For instance, the following configuration attaches a change memory implemented by the DynamicChangeList class.
resource_list_builder: class: DynamicResourceListBuilder uri_path: resourcelist.xml changememory: class: DynamicChangeList uri_path: changelist.xml max_changes: 1000
See the examples in the ./config directory for further details.
