.Dd June 27, 2010 .Dt ATF-CHECK 1 .Os .Sh NAME .Nm atf-check .Nd executes a command and analyzes its results .Sh SYNOPSIS .Nm .Op Fl s Ar qual:value .Op Fl o Ar action:arg ... .Op Fl e Ar action:arg ... .Op Fl x .Ar command .Nm .Fl h .Sh DESCRIPTION .Nm executes a given command and analyzes its results, including exit code, stdout and stderr.

p In the first synopsis form, .Nm will execute the provided command and apply checks specified by arguments. By default it will act as if it was run with .Fl s .Ar exit:0 .Fl o .Ar empty .Fl e .Ar 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).

p In the second synopsis form, .Nm will print information about all supported options and their purpose.

p The following options are available: l -tag -width XqualXvalueXX t Fl h Shows a short summary of all available options and their purpose. t Fl s Ar qual:value Analyzes termination status. Must be one of: l -tag -width signal:<value> -compact t Ar exit:<value> checks that the program exited cleanly and that its exit status is equal to .Va value . The exit code can be omitted altogether, in which case any clean exit is accepted. t Ar ignore ignores the exit check. t Ar signal:<value> checks that the program exited due to a signal and that the signal that terminated it is .Va 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. .El

p Most of these checkers can be prefixed by the .Sq not- string, which effectively reverses the check. t Fl o Ar action:arg Analyzes standard output. Must be one of: l -tag -width inline:<value> -compact t Ar empty checks that stdout is empty t Ar ignore ignores stdout t Ar file:<path> compares stdout with given file t Ar inline:<value> compares stdout with inline value t Ar match:<regexp> looks for a regular expression in stdout t Ar save:<path> saves stdout to given file .El

p Most of these checkers can be prefixed by the .Sq not- string, which effectively reverses the check. t Fl e Ar action:arg Analyzes standard error (syntax identical to above) t Fl x Executes .Ar command as a shell command line, executing it with the system shell defined by .Va ATF_SHELL in .Xr atf-config 1 . You should avoid using this flag if at all possible to prevent shell quoting issues. .El .Sh EXIT STATUS .Nm exits 0 on success, and other (unspecified) value on failure. .Sh EXAMPLES d -literal -offset indent # 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\etyy\en" \e 'echo foobar ; printf "xx\etyy\en" >&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 .Ed .Sh SEE ALSO .Xr atf-config 1 , .Xr atf 7
