====== How to open an extension with the junit tenant ===== When finding errors in complex integration tests, it is useful to start HMC or other extension on the junit tenant to check what data is stored there. To do this please follow these steps: * Open **HAC** * Go to Platform > Tenants * Go to the junit Tenant * Click on the button **Activate** * Now go to your extension adding **;tenantID=junit** at the end of the url. For example, to log into HMC use: http://localhost:9001/hmc/hybris;tenantID=junit Once the junit tenant active is, you can start any extension with the URL suffix above to see what it is stored on that tenant. It is also possible to activate and use the extensions **with other tenants**. FIXME Check if this procedure works on newer versions of Hybris and on the backoffice extensions --Based on Hybris 4.8.17
