26.Dt ATF-CHECK 1
27.Os
28.Sh NAME
29.Nm atf-check
30.Nd executes a command and analyzes its results
31.Sh SYNOPSIS
32.Nm
33.Op Fl s Ar qual:value
34.Op Fl o Ar action:arg ...
35.Op Fl e Ar action:arg ...
36.Op Fl x
37.Ar command
38.Sh DESCRIPTION
39.Nm
40executes a given command and analyzes its results, including
41exit code, stdout and stderr.
42.Pp
43.Em Test cases must use
44.Em Xr atf-sh 3 Ns ' Ns s
45.Em Nm atf_check
46.Em builtin function instead of calling this utility directly.
47.Pp
48In the first synopsis form,
49.Nm
50will execute the provided command and apply checks specified
51by arguments.
52By default it will act as if it was run with
53.Fl s
54.Ar exit:0
55.Fl o
56.Ar empty
57.Fl e
58.Ar empty .
59Multiple checks for the same output channel are allowed and, if specified,
60their results will be combined as a logical and (meaning that the output must
61match all the provided checks).
62.Pp
63In the second synopsis form,
64.Nm
65will print information about all supported options and their purpose.
66.Pp
67The following options are available:
68.Bl -tag  -width XqualXvalueXX
69.It Fl s Ar qual:value
70Analyzes termination status.
71Must be one of:
72.Bl -tag -width signal:<value> -compact
73.It Ar exit:<value>
74checks that the program exited cleanly and that its exit status is equal to
75.Va value .
76The exit code can be omitted altogether, in which case any clean exit is
77accepted.
78.It Ar ignore
79ignores the exit check.
80.It Ar signal:<value>
81checks that the program exited due to a signal and that the signal that
82terminated it is
83.Va value .
84The signal can be specified both as a number or as a name, or it can also
85be omitted altogether, in which case any signal is accepted.
86.El
87.Pp
88Most of these checkers can be prefixed by the
89.Sq not-
90string, which effectively reverses the check.
91.It Fl o Ar action:arg
92Analyzes standard output.
93Must be one of:
94.Bl -tag -width inline:<value> -compact
95.It Ar empty
96checks that stdout is empty
97.It Ar ignore
98ignores stdout
99.It Ar file:<path>
100compares stdout with given file
101.It Ar inline:<value>
102compares stdout with inline value
103.It Ar match:<regexp>
104looks for a regular expression in stdout
105.It Ar save:<path>
106saves stdout to given file
107.El
108.Pp
109Most of these checkers can be prefixed by the
110.Sq not-
111string, which effectively reverses the check.
112.It Fl e Ar action:arg
113Analyzes standard error (syntax identical to above)
114.It Fl x
115Executes
116.Ar command
117as a shell command line, executing it with the system shell defined by
118.Va ATF_SHELL .
119You should avoid using this flag if at all possible to prevent shell quoting
120issues.
121.El
122.Sh EXIT STATUS
123.Nm
124exits 0 on success, and other (unspecified) value on failure.
125.Sh ENVIRONMENT
126.Bl -tag -width ATFXSHELLXX -compact
127.It Va ATF_SHELL
128Path to the system shell to be used when the
129.Fl x
130is given to run commands.
131.El
132.Sh EXAMPLES
133The following are sample invocations from within a test case.
134Note that we use the
135.Nm atf_check
136function provided by
137.Xr atf-sh 3
138instead of executing
139.Nm
140directly:
141.Bd -literal -offset indent
142# Exit code 0, nothing on stdout/stderr
143atf_check 'true'
144
145# Typical usage if failure is expected
146atf_check -s not-exit:0 'false'
147
148# Checking stdout/stderr
149echo foobar >expout
150atf_check -o file:expout -e inline:"xx\etyy\en" \e
151    'echo foobar ; printf "xx\etyy\en" >&2'
152
153# Checking for a crash
154atf_check -s signal:sigsegv my_program
155
156# Combined checks
157atf_check -o match:foo -o not-match:bar echo foo baz
