GLOBAL OPTIONS:
--config value, -c value Location of the client config file. If not specified and the default does not exist, the program's directory is searched as well (default: "/etc/crictl.yaml") [$CRI_CONFIG_FILE]
--debug, -D Enable debug mode (default: false)
--image-endpoint value, -i value Endpoint of CRI image manager service (default: uses 'runtime-endpoint' setting) [$IMAGE_SERVICE_ENDPOINT]
--runtime-endpoint value, -r value Endpoint of CRI container runtime service (default: uses in order the first successful one of [unix:///var/run/dockershim.sock unix:///run/containerd/containerd.sock unix:///run/crio/crio.sock unix:///var/run/cri-dockerd.sock]). Default is now deprecated and the endpoint should be set instead. [$CONTAINER_RUNTIME_ENDPOINT]
--timeout value, -t value Timeout of connecting to the server in seconds (e.g. 2s, 20s.). 0 or less is set to default (default: 2s)
--help, -h show help
critest
root@kali:~# critest -h
Controlling Test Order
--ginkgo.seed [int] (default: randomly generated by Ginkgo)
The seed used to randomize the spec suite.
--ginkgo.randomize-all
If set, ginkgo will randomize all specs together. By default, ginkgo only
randomizes the top level Describe, Context and When containers.
Controlling Test Parallelism
These are set by the Ginkgo CLI, do not set them manually via go test.
Use ginkgo -p or ginkgo -procs=N instead.
--ginkgo.parallel.process [int] (default: 1)
This worker process's (one-indexed) process number. For running specs in
parallel.
--ginkgo.parallel.total [int] (default: 1)
The total number of worker processes. For running specs in parallel.
--ginkgo.parallel.host [string] (default: set by Ginkgo CLI)
The address for the server that will synchronize the processes.
Filtering Tests
--ginkgo.label-filter [expression]
If set, ginkgo will only run specs with labels that match the label-filter.
The passed-in expression can include boolean operations (!, &&, ||, ','),
groupings via '()', and regular expressions '/regexp/'. e.g. '(cat || dog)
&& !fruit'
--ginkgo.focus [string]
If set, ginkgo will only run specs that match this regular expression. Can
be specified multiple times, values are ORed.
--ginkgo.skip [string]
If set, ginkgo will only run specs that do not match this regular
expression. Can be specified multiple times, values are ORed.
--ginkgo.focus-file [file (regexp) | file:line | file:lineA-lineB | file:line,line,line]
If set, ginkgo will only run specs in matching files. Can be specified
multiple times, values are ORed.
--ginkgo.skip-file [file (regexp) | file:line | file:lineA-lineB | file:line,line,line]
If set, ginkgo will skip specs in matching files. Can be specified multiple
times, values are ORed.
Failure Handling
--ginkgo.fail-on-pending
If set, ginkgo will mark the test suite as failed if any specs are pending.
--ginkgo.fail-fast
If set, ginkgo will stop running a test suite after a failure occurs.
--ginkgo.flake-attempts [int] (default: 0 - failed tests are not retried)
Make up to this many attempts to run each spec. If any of the attempts
succeed, the suite will not be failed.
Controlling Output Formatting
--ginkgo.no-color
If set, suppress color output in default reporter.
--ginkgo.v
If set, emits more output including GinkgoWriter contents.
--ginkgo.vv
If set, emits with maximal verbosity - includes skipped and pending tests.
--ginkgo.succinct
If set, default reporter prints out a very succinct report
--ginkgo.trace
If set, default reporter prints out the full stack trace when a failure
occurs
--ginkgo.show-node-events
If set, default reporter prints node > Enter and < Exit events when specs
fail
--ginkgo.json-report [filename.json]
If set, Ginkgo will generate a JSON-formatted test report at the specified
location.
--ginkgo.junit-report [filename.xml]
If set, Ginkgo will generate a conformant junit test report in the specified
file.
--ginkgo.teamcity-report [filename]
If set, Ginkgo will generate a Teamcity-formatted test report at the
specified location.
Debugging Tests
In addition to these flags, Ginkgo supports a few debugging environment
variables. To change the parallel server protocol set GINKGO_PARALLEL_PROTOCOL
to HTTP. To avoid pruning callstacks set GINKGO_PRUNE_STACK to FALSE.
--ginkgo.dry-run
If set, ginkgo will walk the test hierarchy without actually running
anything. Best paired with -v.
--ginkgo.poll-progress-after [duration] (default: 0)
Emit node progress reports periodically if node hasn't completed after this
duration.
--ginkgo.poll-progress-interval [duration] (default: 10s)
The rate at which to emit node progress reports after poll-progress-after
has elapsed.
--ginkgo.source-root [string]
The location to look for source code when generating progress reports. You
can pass multiple --source-root flags.
--ginkgo.timeout [duration] (default: 1h)
Test suite fails if it does not complete within the specified timeout.
--ginkgo.grace-period [duration] (default: 30s)
When interrupted, Ginkgo will wait for GracePeriod for the current running
node to exit before moving on to the next one.
--ginkgo.output-interceptor-mode [dup, swap, or none]
If set, ginkgo will use the specified output interception strategy when
running in parallel. Defaults to dup on unix and swap on windows.
