.Nd executes a command and analyzes its results
|

.Sh SYNOPSIS
|
|
.Nm

.Ar command
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
executes a given command and analyzes its results, including
|
|
exit code, stdout and stderr.
|
|
.Pp
|
|
.Em Test cases must use
|
|
.Em Xr atf-sh 3 Ns ' Ns s
|
|
.Em Nm atf_check
|
|
.Em builtin function instead of calling this utility directly.
|
|
.Pp
|
|
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).
|
|
.Pp
|
|
In the second synopsis form,
|
|
.Nm
|
|
will print information about all supported options and their purpose.
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width XqualXvalueXX
|
|
.It Fl s Ar qual:value
|
|
Analyzes termination status.
|
|
Must be one of:
|
|
.Bl -tag -width signal:<value> -compact
|
|
.It 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.
|
|
.It Ar ignore
|
|
ignores the exit check.
|
|
.It 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
|
|
.Pp
|
|
Most of these checkers can be prefixed by the
|
|
.Sq not-
|
|
string, which effectively reverses the check.
|
|
.It Fl o Ar action:arg
|
|
Analyzes standard output.
|
|
Must be one of:
|
|
.Bl -tag -width inline:<value> -compact
|
|
.It Ar empty
|
|
checks that stdout is empty
|
|
.It Ar ignore
|
|
ignores stdout
|
|
.It Ar file:<path>
|
|
compares stdout with given file
|
|
.It Ar inline:<value>
|
|
compares stdout with inline value
|
|
.It Ar match:<regexp>
|
|
looks for a regular expression in stdout
|
|
.It Ar save:<path>
|
|
saves stdout to given file
|
|
.El
|
|
.Pp
|
|
Most of these checkers can be prefixed by the
|
|
.Sq not-
|
|
string, which effectively reverses the check.
|
|
.It Fl e Ar action:arg
|
|
Analyzes standard error (syntax identical to above)
|
|
.It Fl x
|
|
Executes
|
|
.Ar command
|
|
as a shell command line, executing it with the system shell defined by
|
|
.Va ATF_SHELL .
|
|
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 ENVIRONMENT
|
|
.Bl -tag -width ATFXSHELLXX -compact
|
|
.It Va ATF_SHELL
|
|
Path to the system shell to be used when the
|
|
.Fl x
|
|
is given to run commands.
|
|
.El
|
|
.Sh EXAMPLES
|
|
The following are sample invocations from within a test case.
|
|
Note that we use the
|
|
.Nm atf_check
|
|
function provided by
|
|
.Xr atf-sh 3
|
|
instead of executing
|
|
.Nm
|
|
directly:
|
|
.Bd -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
