-
-* im.status.gradle.gpshell = the path to the gpshell executable
-* im.status.gradle.gpshell.isd = the AID of the issuer security domain
-* im.status.gradle.gpshell.mac_key = the MAC key for the ISD

-* im.status.gradle.gpshell.kvn = the Key Version Number for the ISD
-* im.status.keycard.test.simulated = true if the test should run on the simulator, false (or anything else) otherwise

 Testing is done with JUnit and performed either on a real card or on [jCardSim](https://github.com/status-im/jcardsim). 
 Although the tests are comprehensive, debugging on the real card is not easy because raw APDUs are not shown in the test 
 log and there is no way to set breakpoints in the applet.
