ATF-RUN(1) BSD General Commands Manual ATF-RUN(1)
atf-run -- executes a collection of test programs
atf-run [-v var1=value1 [.. -v varN=valueN]] [test_program1 [.. test_programN]]
atf-run executes a collection of test programs or, in other words, a complete test suite. The results of each test program 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 vari-
ables 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
program names are given as part of the command line, those are the ones executed instead of the complete list.
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.
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
3. Configuration variables defined in the system-wide test-suite-specific configuration file. This lives in
4. Configuration variables defined in the user-specific configuration file shared among all test suites. This lives in
5. Configuration variables defined in the user-specific test-suite-specific configuration file. This lives in
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 conve-
nience of the user.
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:
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:
atf_tps_writer_info "uptime" "$(uptime)"
