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