# test (test functionalities) ### Command > test ### Syntax > test \[Task (string)] ### Description Tests the functionalities of HyperDbg in the running system. ### Parameters **\[Task (string)]** Different options are used mostly for debugging the internal mechanisms of HyperDbg.
OptionDescription
queryShows the state of each core (e.g., halted or not)
poolShows the state of memory pool allocation and pre-allocation
breakpointTurns the interception of breakpoints (#BP) ON/OFF.
trapTurns the interception of debug breaks (#DB) ON/OFF.
trap-statusShows the state of simultaneously debugging threads that HyperDbg sets the trap flag on them
### Examples The following command shows how to check all the test-cases. ```cpp HyperDbg> test ``` The following command shows the '**lock**' state of each core. ``` 0: kHyperDbg> test query ================================================ Debugging Lock Info ================================================ (04:32:04.709 - core : 0 - vmx-root? yes) [+] Information (KdQuerySystemState:1603) | Core : 0 is locked (04:32:04.709 - core : 0 - vmx-root? yes) [+] Information (KdQuerySystemState:1603) | Core : 1 is locked (04:32:04.709 - core : 0 - vmx-root? yes) [+] Information (KdQuerySystemState:1603) | Core : 2 is locked (04:32:04.709 - core : 0 - vmx-root? yes) [+] Information (KdQuerySystemState:1603) | Core : 3 is locked (04:32:04.709 - core : 0 - vmx-root? yes) [+] Information (KdQuerySystemState:1603) | Core : 4 is locked (04:32:04.709 - core : 0 - vmx-root? yes) [+] Information (KdQuerySystemState:1603) | Core : 5 is locked ================================================ NMI Receiver State =======+========================================= (04:32:04.709 - core : 0 - vmx-root? yes) [+] Information (KdQuerySystemState:1625) | Core : 0 - not called from an NMI handler (through the immediate VM-exit mechanism) (04:32:04.709 - core : 0 - vmx-root? yes) [+] Information (KdQuerySystemState:1625) | Core : 1 - not called from an NMI handler (through the immediate VM-exit mechanism) (04:32:04.709 - core : 0 - vmx-root? yes) [+] Information (KdQuerySystemState:1625) | Core : 2 - not called from an NMI handler (through the immediate VM-exit mechanism) (04:32:04.709 - core : 0 - vmx-root? yes) [+] Information (KdQuerySystemState:1625) | Core : 3 - not called from an NMI handler (through the immediate VM-exit mechanism) (04:32:04.709 - core : 0 - vmx-root? yes) [+] Information (KdQuerySystemState:1625) | Core : 4 - not called from an NMI handler (through the immediate VM-exit mechanism) (04:32:04.709 - core : 0 - vmx-root? yes) [+] Information (KdQuerySystemState:1625) | Core : 5 - not called from an NMI handler (through the immediate VM-exit mechanism) ``` The following command shows the state of pool allocation. ``` 0: kHyperDbg> test pool (04:32:04.709 - core : 0 - vmx-root? yes) [+] Information (PoolManagerShowPreAllocatedPools:218) | Pool details, Pool intention: 4 | Pool address: ffffc1059fdd1cc0 | Pool state: free | Should be freed: false | Already freed: false (04:32:04.709 - core : 0 - vmx-root? yes) [+] Information (PoolManagerShowPreAllocatedPools:218) | Pool details, Pool intention: 4 | Pool address: ffffc1059fdd1f00 | Pool state: free | Should be freed: false | Already freed: false (04:32:04.709 - core : 0 - vmx-root? yes) [+] Information (PoolManagerShowPreAllocatedPools:218) | Pool details, Pool intention: 4 | Pool address: ffffc1059fdd1b40 | Pool state: free | Should be freed: false | Already freed: false ... ``` The following command is used to turn OFF/ON the breakpoint (#BP) interception. ``` 0: kHyperDbg> test breakpoint on breakpoint interception (#BP) is activated 0: kHyperDbg> test breakpoint off breakpoint interception (#BP) is deactivated from now, the breakpoints will be re-injected into the guest debuggee ``` The following command is used to turn OFF/ON the debug break (#DB) interception. ``` 0: kHyperDbg> test breakpoint on debug break interception (#DB) is activated 4: kHyperDbg> test trap off debug break interception (#DB) is deactivated from now, the debug breaks will be re-injected into the guest debuggee ``` The following command shows the state of simultaneously debugging threads that HyperDbg sets the trap flag on them. ``` 0: kHyperDbg> test trap-status (01:14:17.385 - core : 0 - vmx-root? yes) [+] Information (KdQueryRflagTrapState:1568) | Number of valid entries: 0x0 (Please be aware that only top 0x0 items are considered valid.
