ATF-CHECK(1)                General Commands Manual               ATF-CHECK(1)

NAME
     atf-check - executes a command and analyzes its results

SYNOPSIS
     atf-check [-s qual:value] [-o action:arg ...] [-e action:arg ...] [-x]
               command

DESCRIPTION
     atf-check executes a given command and analyzes its results, including
     exit code, stdout and stderr.

     atf-check will execute the provided command and apply checks specified by
     arguments.  By default it will act as if it was run with -s exit:0 -o
     empty -e empty.  Multiple checks for the same output channel are allowed
     and, if specified, their results will be combined as a logical and
     (meaning that the output must match all the provided checks).

     The following options are available:

     -s qual:value  Analyzes termination status.  Must be one of:
                    exit:<value>    checks that the program exited cleanly and
                                    that its exit status is equal to value.
                                    The exit code can be omitted altogether,
                                    in which case any clean exit is accepted.
                    ignore          ignores the exit check.
                    signal:<value>  checks that the program exited due to a
                                    signal and that the signal that terminated
                                    it is value.  The signal can be specified
                                    both as a number or as a name, or it can
                                    also be omitted altogether, in which case
                                    any signal is accepted.

                    Most of these checkers can be prefixed by the `not-'
                    string, which effectively reverses the check.

     -o action:arg  Analyzes standard output.  Must be one of:
                    empty           checks that stdout is empty
                    ignore          ignores stdout
                    file:<path>     compares stdout with given file
                    inline:<value>  compares stdout with inline value
                    match:<regexp>  looks for a regular expression in stdout
                    save:<path>     saves stdout to given file

                    Most of these checkers can be prefixed by the `not-'
                    string, which effectively reverses the check.

     -e action:arg  Analyzes standard error (syntax identical to above)

     -x             Executes command as a shell command line, executing it
                    with the system shell defined by ATF_SHELL in
                    atf-config(1).  You should avoid using this flag if at all
                    possible to prevent shell quoting issues.

EXIT STATUS
     atf-check exits 0 on success, and other (unspecified) value on failure.

EXAMPLES
           # Exit code 0, nothing on stdout/stderr
           atf-check 'true'

           # Typical usage if failure is expected
           atf-check -s not-exit:0 'false'

           # Checking stdout/stderr
           echo foobar >expout
           atf-check -o file:expout -e inline:"xx\tyy\n" \
               'echo foobar ; printf "xx\tyy\n" >&2'

           # Checking for a crash
           atf-check -s signal:sigsegv my_program

           # Combined checks
           atf-check -o match:foo -o not-match:bar echo foo baz
