# 8. AN preparing the synchronization tests These are the steps that will be taken before the tests: #### 8.1. Backup before testing Perform a dump backup of the Scorpio data so we can restore it afterwards and delete the data of your DB. Remember to put it out of your docker or it will disappear if you restart your AN. How you could delete the data
kubectl get pvc -n <namespace> kubectl delete pvc postgris-0 kubectl delete pod postgis-0 -n <namespace> --grace-period=0 --force
If you change any of your settings, be careful with the PVC's; they could interfere negatively. It's advisable to remove them whenever there's a major change. #### 8.2. Configuration for testing Add the externalAccessNodesUrls configuration inside the APP block as shown on the image below, which should be adapted for these tests. (It will be reconfigured later to point to the correct location.)
externalAccessNodesUrls: enableCustomUrls: true customUrls: "https://desmos.dome-marketplace-lcl.org"
How it should looks #### 8.3. Review the values configuration and Trusted Lists registry Verify that you complete all the steps above and your machine is correctly registered in the Trusted lists [Trusted Lists github](https://github.com/DOME-Marketplace/trust-framework/tree/main/sbx) #### 8.4. Install AN After doing the previous steps, be sure that you installed your AN correctly. I'm leaving these commands here in case they're helpful. Remember that you need to throw these commands inside your values.yaml directory.
helm dependency build helm install myaccessnode . -f values.yaml
If you already have the current AN installed, uninstall it to prevent any mixing between the new and old configurations. helm uninstall myaccessnode #### 8.5. Desmos running without errors Confirm that your desmos pod is working correctly. You could check it with kubectl logs desmos-648bdbc988-pl2ft -n <your-namespace> -c desmos #### 8.6. Send an email Send an email to [d](mailto:domesupport@in2.es)[omesupport@in2.es](mailto:domesupport@in2.es) informing them that everything is ready to perform the integration tests.
