ATF-RUN(1)

NAME
atf-run - executes a collection of tests

SYNOPSIS
atf-run [-v var1=value1 [.. -v varN=valueN]] [test1 [.. testN]]
atf-run -h

DESCRIPTION
atf-run executes a collection of test cases, test programs, or a complete test suite. The results of each test are collected by the tool, and are then multiplexed into a single machine-parseable report; see atf-formats(5) for more details. This report can later be transformed into many different and saner formats using the atf-report tool.

The list of test programs to execute is read from an Atffile present in the current directory. This file describes the test suite stored in the directory it lives in, which aside from the list of test programs also includes meta-data and configuration variables.

atf-run is also in charge of reading the configuration files that tune the behavior of each test program and passing down the necessary variables to them. More details on how this is done are given in the Configuration section.

In the first synopsis form, atf-run parses the Atffile in the current directory and runs all the test programs specified in it. If any test arguments are given as part of the command line, those tests are executed instead of the complete list. Each test argument can be either the name of a test program, or a string of the form test_program:test_case to execute a single test case.

In the second synopsis form, atf-run will print information about all supported options and their purpose.

The following options are available:

-h  Shows a short summary of all available options and their purpose.

-v var=value
    Sets the configuration variable var to the given value value.

  Configuration
atf-run reads configuration data from multiple places. After all of these places have been analyzed, a list of variable-value pairs are passed to the test programs to be run.

The following locations are scanned for configuration data, in order. Items down the list override values defined above them:

1.  Configuration variables defined in the Atffile.

2.  Configuration variables defined in the system-wide configuration file shared among all test suites. This lives in ${ATF_CONFDIR}/common.conf.

3.  Configuration variables defined in the system-wide test-suite-specific configuration file. This lives in ${ATF_CONFDIR}/<test-suite>.conf.

4.  Configuration variables defined in the user-specific configuration file shared among all test suites. This lives in ${HOME}/.atf/common.conf.

5.  Configuration variables defined in the user-specific test-suite-specific configuration file. This lives in ${HOME}/.atf/<test-suite>.conf.

6.  Configuration variables provided as part of the command line through the -v option.

The value of ATF_CONFDIR in the above list determined as detailed in atf-config(1).

The following configuration variables are globally recognized:

unprivileged-user
    The name of the system user that atf-run will drop root privileges into for test cases defining ‘require.user=unprivileged’. Note that this is not provided for security purposes; this feature is only for the convenience of the user.

  Hooks
atf-run's internal behavior can be customized by the system administrator and the user by means of hooks. These hooks are written in the shell script language for simplicity and are stored in the following files, which are read in the order provided below:

1.  ${ATF_CONFDIR}/atf-run.hooks

2.  ${HOME}/.atf/atf-run.hooks

The following hooks are supported:

info_start_hook
    Called before atf-run executes any test program. The purpose of this hook is to write additional ‘info’ stanzas to the top of the output report; these are defined by the ‘application/X-atf-tps format’ described in atf-formats(5). Always use the ‘atf_tps_writer_info’ function to print these.

    This takes no parameters.

info_end_hook
    Similar to ‘info_start_hook’ but executed after all test programs have been run so that additional ‘info’ stanzas can be added to the bottom of the output report.

    This takes no parameters.

All hooks are accompanied by a function named ‘default_<hook_name>’ that can be executed by them to invoke the default behavior built into atf-run. For example, in order to extend the default ‘info_start_hook’ hook, we could write the following function:

    info_start_hook()
    {
        default_info_start_hook "${@}"
        atf_tps_writer_info "uptime" "$(uptime)"
    }
