Run, Watch, Report

rlRun

Run command with optional comment and make sure its exit code matches expectations.

    rlRun [-t] [-l] [-c] [-s] command [status[,status...] [comment]]
-t

If specified, stdout and stderr of the command output will be tagged with strings 'STDOUT: ' and 'STDERR: '.

-l

If specified, output of the command (tagged, if -t was specified) is logged using rlLog function. This is intended for short outputs, and therefore only last 50 lines are logged this way. Longer outputs should be analysed separately, or uploaded via rlFileSubmit or rlBundleLogs.

-c

Same as -l, but only log the command output if it failed.

-s

Store stdout and stderr to a file (mixed together, as the user would see it on a terminal) and set $rlRun_LOG variable to name of the file. $rlRun_LOG is now actually an array where the first index holds the last reference to the file. Thus its behavior is not changed if used without an index. The array is consumed by the rlJournalEnd function to remove the leftover files, so no manual files removal is needed anymore. Note that if you need to use such a file after calling the rlJournalEnd function you need to create your own copy of the respective file. When -t option is used, the content of the file becomes tagged too.

If the -s option is not used, $rlRun_LOG is not modified and keeps its content from the last “rlRun -s”.

command

Command to run.

status

Expected exit code(s). Optional, default 0. If you expect more exit codes, separate them with comma (e.g. “0,1” when both 0 and 1 are OK and expected), or use from-to notation (i.e. “2-5” for “2,3,4,5”), or combine them (e.g. “2-4,26” for “2,3,4,26”).

comment

Short summary describing the action (optional, but recommended - explain what you are doing here).

Returns the exit code of the command run. Asserts PASS when command\'s exit status is in the list of expected exit codes.

Note:

  • The output of rlRun is buffered when using -t, -l or -s option (they use unix pipes, which are buffered by nature). If you need an unbuffered output just make sure that expect package is installed on your system (its “unbuffer” tool will automatically be used to produce unbuffered output).
  • Be aware that there are some variables which can collide with your code executed within rlRun. You should avoid using __INTERNAL_rlRun_* variables.
  • When any of -t -l, -c, or -s option is used, special file descriptors 111 and 112 are used to avoid the issue with incomplete log file, bz1361246. As there might be an indefinite loop, there's a timeout of two minutes implemented as a fix for bz1416796. Also an error message is issued to signal the possibility of running subprocess which keeps the file descriptors open.

    Do not use these options if you expect process forking and continuouse run. Try your own apropriate solution instead.

Warning: using unbuffer tool is now disabled because of bug 547686.

rlWatchdog

Run command. If it does not finish in specified time, then kill it using signal. Note that the command is executed in a sub-shell so modified environment (e.g. set variables) is not relfected in the test environment.

    rlWatchdog command timeout [signal] [callback]
command

Command to run.

timeout

Timeout to wait, in seconds.

signal

Signal to use (optional, default KILL).

callback

Callback function to be called before the signal is send (optional, none by default). The callback function will have one argument available — PGID of the process group.

Returns 0 if the command ends normally, without need to be killed.

rlReport

Report test result to the test harness. The command to be used for reporting is set by the respective plugin. You can also use the $BEAKERLIB_COMMAND_REPORT_RESULT variable to use your custom command.

    rlReport name result [score] [log]
name

Name of the test result.

result

Result (one of PASS, WARN, FAIL). If called with something else, will use WARN.

score

Test score (optional).

log

Optional log file to be submitted instead of default OUTPUTFILE.

rlCmpVersion

Compare two given versions composed by numbers and letters divided by dot (.), underscore (_), or dash (-).

    rlCmpVersion ver1 ver2

If ver1 = ver2, sign '=' is printed to stdout and 0 is returned. If ver1 > ver2, sign '>' is printed to stdout and 1 is returned. If ver1 < ver2, sign '<' is printed to stdout and 2 is returned.

rlTestVersion

Test releation between two given versions based on given operator.

    rlTestVersion ver1 op ver2
op

Operator defining the logical expression. It can be '=', '==', '!=', '<', '<=', '=<', '>', '>=', or '=>'.

Returns 0 if the expresison ver1 op ver2 is true; 1 if the expression is false and 2 if something went wrong.

Release Info

    rlIsFedora 30 32

  Returns 0 if we are running Fedora 30 or 32.

rlIsCentOS

    rlIsCentOS [VERSION_SPEC]...
VERSION_SPEC

Argument specifies version of particular CentOS distribution, eg. 7, “>7”.

For more details see description of “rlIsOSVersion”.

Returns 0 when we're running on CentOS. With given version specification in arguments returns 0 if the particular CentOS version is running.

Prototype:

    rlIsCentOS

  Returns 0 if we are running on CentOS.

    rlIsCentOS 7.1 6

  Returns 0 if we are running CentOS 7.1 or any CentOS 6.

rlIsOS

    rlIsOS ID
ID

Argument is based on contents of /etc/os-release. Possible options of ID are e.g. fedora, rhel, centos, ol.

Returns 0 when we're running on system with respective ID. Returns 1 when parameter does not match with ID in os-release. Returns 2 when there is no ID defined. Returns 3 when no argument is given.

Prototype:

    rlIsOS rhel

  Returns 0 if we are running on RHEL.

rlIsOSLike

    rlIsOSLike ID_LIKE
ID_LIKE

Argument is based on contents of /etc/os-release. Possible options of ID_LIKE are e.g. fedora, rhel.

Returns 0 when we're running on system with requested ID_LIKE. Returns 1 when parameter does not match with ID nor ID_LIKE in os-release. Returns 2 when there is no ID or ID_LIKE defined. Returns 3 when no argument is given.

Prototype:

    rlIsOSLike rhel

  Returns 0 if we are running on RHEL, CentOS, Rocky Linux, etc..

    rlIsOSLike fedora

  Returns 0 if we are running on Fedora, RHEL, CentOS, Oracle Linux, etc..

rlIsOSVersion

    rlIsOsVersion VERSION_SPEC...
VERSION_SPEC

Parameter is based on VERSION_ID in /etc/os-release. It consists of either major or major.minor refering to a particular release.

It accepts multiple arguments separated by space (8.1 8.2 8.3 9).

To specify a group of distributions optional operator can be passed in argument together with the version number as one string ('>8.5'). Operator can be '<', '<=', '=<', '=', '>', '>=' matching whether the currently installed version is lesser, lesser or equal, equal, equal or greater, greater than the version number supplied as second half of the argument.

Note that when using >/< operators you have to either put the argument in quotes or escape the operators to avoid them being interpreted as bash redirection operator.

Returns 0 when we're running distribution of the particular version requested by the argument.

It usually follows after rlIsOS and rlIsOSLike.

Be cautious when using together with rlIsOSLike as different distributions may use different versioning schema.

Prototype:

   rlIsOSVersion 6 7 9

  Returns 0 if we are running distribution with VERSION_ID 6, 7 or 9.

    rlIsOSVersion 7.8 8

  Returns 0 if we are running distribution 7.8 or any 8.

    rlIsOSVersion ">=7.5" or rlIsOSVersion \>=7.5

  Returns 0 if we are running distribution 7.5 or higher (both minors or majors).

Note:

    rlIsOSVersion '<7.5' || rlIsOSVersion '<8.5'

  would also cover 7.9 as it is less than 8.5, which is not what you want.
  So if you want to construct a condition for a distribution <7.5 within the major 7 or
  a distribution <8.5 within the major 8 you actually need to use following construct:

    rlIsOSVersion 7 && rlIsOSVersion '<7.5' || rlIsOSVersion 8 && rlIsOSVersion '<8.5'

  This returns 0 when running distribution less than 7.5 and less then 8.5, but not 7.9 (nor 6.9).

rlIsRHELLike

    rlIsRHELLike [VERSION_SPEC]...
VERSION_SPEC

Argument specifies version of particular RHEL distribution, eg. 8, 8.4 “>8.4”.

For more details see description of “rlIsOSVersion”.

Returns 0 when we're running on RHEL-like distribution. These are considered to be RHEL, CentOS, Rocky Linux, etc.. With given version specification in arguments returns 0 if the particular version of RHEL-like distribution is running.

Prototype:

    rlIsRHELLike

  Returns 0 if we are running on RHEL-like system.

    rlIsRHELLike ">=6"

  Returns 0 if we are running on RHEL-like distribution of version 6.0 or higher.
