Unless certain properties are defined, the tests that require them will 155be skipped. 156.Pp 157Test suites are configured by defining their configuration 158variables in 159.Pa /usr/local/etc/kyua/kyua.conf . 160The format of this file is detailed in 161.Xr kyua.conf 5 . 162.Pp 163The following configuration variables are available in the 164.Fx 165Test Suite: 166.Bl -tag -width "allow_sysctl_side_effects" 167.It allow_devfs_side_effects 168If defined, enables tests that may destroy and recreate semipermanent device 169nodes, like disk devices. 170Without this variable, tests may still create and destroy devices nodes that 171are normally transient, like /dev/tap* and /dev/pts*, as long as they clean 172them up afterwards. 173However, tests that require this variable have a relaxed cleanup requirement; 174they must recreate any devices that they destroyed, but not necessarily with 175the same devnames. 176.It allow_sysctl_side_effects 177Enables tests that change globally significant 178.Xr sysctl 8 179variables. 180The tests will undo any changes in their cleanup phases. 181.It disks 182Must be set to a space delimited list of disk device nodes. 183Tests that need destructive access to disks must use these devices. 184Tests are not required to preserve any data present on these disks. 185.It fibs 186Must be set to a space delimited list of FIBs (routing tables). 187Tests that need to modify a routing table may use any of these. 188Tests will cleanup any new routes that they create. 189.El 190.Ss What to do if something fails? 191If there is 192.Em any failure 193during the execution of the test suite, please consider reporting it to the 194.Fx 195developers so that the failure can be analyzed and fixed. 196To do so, either send a message to the appropriate mailing list or file a 197problem report. 198For more details please refer to: 199.Bl -bullet -offset indent -compact 200.It 201.Lk http://lists.freebsd.org/ "FreeBSD Mailing Lists" 202.It 203.Lk http://www.freebsd.org/support.html "Problem Reporting" 204.El 205.Sh FILES 206.Bl -tag -compact -width usrXlocalXetcXkyuaXkyuaXconfXX 207.It Pa /usr/local/etc/kyua/kyua.conf 208System-wide configuration file for 209.Xr kyua 1 . 210.It Pa ~/.kyua/kyua.conf 211User-specific configuration file for 212.Xr kyua 1 ; 213overrides the system file. 214.It Pa ~/.kyua/store.db 215Default result database used by Kyua. 216.It Pa /usr/tests/ 217Location of the 218.Fx 219Test Suite. 220.It Pa /usr/tests/Kyuafile 221Top-level test suite definition file. 222.El 223.Sh SEE ALSO 224.Xr kyua 1 , 225.Xr build 7 226.Sh HISTORY 227The 228.Fx 229Test Suite first appeared in 230.Fx 10.1 . 231.Pp 232The 233.Nm 234manual page first appeared in 235.Nx 6.0 236and was later ported to 237.Fx 10.1 . 238.Sh AUTHORS 239.An Julio Merino Aq Mt jmmv@FreeBSD.org 240
