common interface to ATF test programs
-v var1=value1 [..
Test programs written using the ATF libraries all share a common user interface,
which is what this manual page describes. NOTE: There is no
binary known as
what is described in this manual page is the command-line
interface exposed by the atf-c, atf-c++ and atf-sh
In the first synopsis form, the test program will execute the
provided test case and print its results to the standard output, unless
otherwise stated by the
-r flag. Optionally, the
test case name can be suffixed by ‘:cleanup’, in which case
the cleanup routine of the test case will be executed instead of the test
case body; see
Note that the test case is executed without isolation, so
it can and probably will create and modify files in the current directory.
To execute test cases in a controller manner, you need a runtime engine that
understands the ATF interface. The recommended runtime engine is
You should only execute test cases by hand for debugging purposes.
In the second synopsis form, the test program will list all
available test cases alongside their meta-data properties in a format that
is machine parseable. This list is processed by
to know how to execute the test cases of a given test program.
The following options are available:
- Lists available test cases alongside a brief description for each of
- Specifies the file that will receive the test case result. If not
specified, the test case prints its results to stdout. If the result of a
test case needs to be parsed by another program, you must use this option
to redirect the result to a file and then read the resulting file from the
other program. Note: do not try to process the stdout of the
test case because your program may break in the future.
- The path to the directory where the test program is located. This is
needed in all cases, except when the test program is being executed from
the current directory. The test program will use this path to locate any
helper data files or utilities.
- Sets the configuration variable var to the value
