A method for testing an internal interface of a reconfigurable radio equipment, RRE, wherein the internal interface is one of (generalized) Multiradio Interface, (g)MURI, (generalized) Reconfigurable Radio Frequency Interface, (g)RRFI or (generalized) Unified Radio Application Interface, (g)URAI, the method comprising: activating a test mode for a first component of the RRE; installing a Reference Radio Application Package, RRAP, to the RRE; sending, by the RRAP, one or more service primitives defined by the internal interface to a second component of the RRE, the one or more service primitives to be provided by the second component to the first component; obtaining an output based on operation of the RRAP based on the one or more service primitives, the output created by the internal interface, wherein for testing the (g)MURI interface, some or all of service primitives as defined in ETSI EN 303 146-1 V1.3.1 and/or ETSI EN 303 681-1 V1.1.2 are fed from a Communication Service Layer, CSL, of the RRE to a Radio Control Framework, RCF, of the RRE and verified by the RRAP, for testing the (g)RRFI interface, some or all of service primitives as defined in ETSI EN 303 146-2 V1.1.5 and/or ETSI EN 303 681-2 V1.1.2 are fed from a Unified Radio Application, URA, of the RRE to a Radio Frequency Tranceiver, RF TRx, of the RRE or vice versa and verified by the RRAP, for testing the (g)URAI interface, some or all of service primitives as defined in ETSI EN 303 146-3 V1.3.1 and/or ETSI EN 303 681-3 V 1.1.2 are fed from the URA to the RCF or vice versa and verified by the RRAP; and validating, by the RRAP, the obtained output. activating a test mode for a first component of the RRE; installing a Reference Radio Application Package, RRAP, to the RRE; sending, by the RRAP, one or more service primitives defined by the internal interface to a second component of the RRE, the one or more service primitives to be provided by the second component to the first component; obtaining an output based on operation of the RRAP based on the one or more service primitives, the output created by the internal interface, wherein for testing the (g)MURI interface, some or all of service primitives as defined in ETSI EN 303 146-1 V1.3.1 and/or ETSI EN 303 681-1 V1.1.2 are fed from a Communication Service Layer, CSL, of the RRE to a Radio Control Framework, RCF, of the RRE and verified by the RRAP, for testing the (g)RRFI interface, some or all of service primitives as defined in ETSI EN 303 146-2 V1.1.5 and/or ETSI EN 303 681-2 V1.1.2 are fed from a Unified Radio Application, URA, of the RRE to a Radio Frequency Tranceiver, RF TRx, of the RRE or vice versa and verified by the RRAP, for testing the (g)URAI interface, some or all of service primitives as defined in ETSI EN 303 146-3 V1.3.1 and/or ETSI EN 303 681-3 V 1.1.2 are fed from the URA to the RCF or vice versa and verified by the RRAP; and validating, by the RRAP, the obtained output. for testing the (g)MURI interface, some or all of service primitives as defined in ETSI EN 303 146-1 V1.3.1 and/or ETSI EN 303 681-1 V1.1.2 are fed from a Communication Service Layer, CSL, of the RRE to a Radio Control Framework, RCF, of the RRE and verified by the RRAP, for testing the (g)RRFI interface, some or all of service primitives as defined in ETSI EN 303 146-2 V1.1.5 and/or ETSI EN 303 681-2 V1.1.2 are fed from a Unified Radio Application, URA, of the RRE to a Radio Frequency Tranceiver, RF TRx, of the RRE or vice versa and verified by the RRAP, for testing the (g)URAI interface, some or all of service primitives as defined in ETSI EN 303 146-3 V1.3.1 and/or ETSI EN 303 681-3 V 1.1.2 are fed from the URA to the RCF or vice versa and verified by the RRAP; and validating, by the RRAP, the obtained output.
