mtutil, part of the Megatest tool suite, documentation at http://www.kiatoa.com/fossils/megatest
version " megatest-version "
license GPL, Copyright Matt Welland 2006-2017
Usage: mtutil action [options]
-h : this help
-manual : show the Megatest user manual
-version : print megatest version (currently " megatest-version ")
Actions:
run : initiate runs
remove : remove runs
rerun : register action for processing
set-ss : set state/status
archive : compress and move test data to archive disk
kill : stop tests or entire runs
db : database utilities
areas, contours, setup : show areas, contours or setup section from megatest.config
gendot : generate a graphviz dot file from pkts.
Contour actions:
process : runs import, rungen and dispatch
Trigger propagation actions:
tsend a=b,c=d... : send trigger info to all recpients in the [listeners] section
tlisten -port N : listen for trigger info on port N
Selectors
-immediate : apply this action immediately, default is to queue up actions
-area areapatt1,area2... : apply this action only to the specified areas
-target key1/key2/... : run for key1, key2, etc.
-test-patt p1/p2,p3/... : % is wildcard
-run-name : required, name for this particular test run
-contour contourname : run all targets for contourname, requires -run-name, -target
-state-status c/p,c/f : Specify a list of state and status patterns
-tag-expr tag1,tag2%,.. : select tests with tags matching expression
-mode-patt key : load testpatt from <key> in runconfigs instead of default TESTPATT
if -testpatt and -tagexpr are not specified
-new state/status : specify new state/status for set-ss
Misc
-start-dir path : switch to this directory before running mtutil
-set-vars V1=1,V2=2 : Add environment variables to a run NB// these are
overwritten by values set in config files.
-log logfile : send stdout and stderr to logfile
-repl : start a repl (useful for extending megatest)
-load file.scm : load and run file.scm
-debug N|N,M,O... : enable debug messages 0-N or N and M and O ...
Utility
db pgschema : emit postgresql schema; do \"mtutil db pgschema | psql -d mydb\"
Examples:
# Start a megatest run in the area \"mytests\"
mtutil run -area mytests -target v1.63/aa3e -mode-patt MYPATT -tag-expr quick
# Start a contour
mtutil run -contour quick -target v1.63/aa3e
