Having kyua in the base system will simplify automated testing in CI and eliminates bootstrapping issues on new platforms. The build of kyua is controlled by WITH(OUT)_TESTS_SUPPORT.

.Ar test_case
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
command provides a mechanism to execute a single test case bypassing some
|
|
of the Kyua infrastructure and allowing the user to poke into the execution
|
|
behavior of the test.
|
|
.Pp
|
|
The test case to run is selected by providing a test filter, described below in
|
|
.Sx Test filters ,
|
|
that matches a single test case.
|
|
The test case is executed and its result is printed as the last line of the
|
|
output of the tool.
|
|
.Pp
|
|
The test executed by
|
|
.Nm
|
|
is run under a controlled environment as described in
|
|
.Sx Test isolation .
|
|
.Pp
|
|
At the moment, the
|
|
.Nm
|
|
command allows the following aspects of a test case execution to be
|
|
tweaked:
|
|
.Bl -bullet
|
|
.It
|
|
Redirection of the test case's stdout and stderr to the console (the
|
|
default) or to arbitrary files.
|
|
See the
|
|
.Fl -stdout
|
|
and
|
|
.Fl -stderr
|
|
options below.
|
|
.El
|
|
.Pp
|
|
The following subcommand options are recognized:
|
|
.Bl -tag -width XX
|
|
.It Fl -build-root Ar path
|
|
Specifies the build root in which to find the test programs referenced
|
|
by the Kyuafile, if different from the Kyuafile's directory.
|
|
See
|
|
.Sx Build directories
|
|
below for more information.
|
|
.It Fl -kyuafile Ar file , Fl k Ar file
|
|
Specifies the Kyuafile to process.
|
|
Defaults to
|
|
.Pa Kyuafile
|
|
file in the current directory.
|
|
.It Fl -stderr Ar path
|
|
Specifies the file to which to send the standard error of the test
|
|
program's body.
|
|
The default is
|
|
.Pa /dev/stderr ,
|
|
which is a special character device that redirects the output to
|
|
standard error on the console.
|
|
.It Fl -stdout Ar path
|
|
Specifies the file to which to send the standard output of the test
|
|
program's body.
|
|
The default is
|
|
.Pa /dev/stdout ,
|
|
which is a special character device that redirects the output to
|
|
standard output on the console.
|
|
.El
|
|
.Pp
|
|
For example, consider the following Kyua session:
|
|
.Bd -literal -offset indent
|
|
$ kyua test
|
|
kernel/fs:mkdir -> passed
|
|
kernel/fs:rmdir -> failed: Invalid argument
|
|
|
|
1/2 passed (1 failed)
|
|
.Ed
|
|
.Pp
|
|
At this point, we do not have a lot of information regarding the
|
|
failure of the
|
|
.Sq kernel/fs:rmdir
|
|
test.
|
|
We can run this test through the
|
|
.Nm
|
|
command to inspect its output a bit closer, hoping that the test case is
|
|
kind enough to log its progress:
|
|
.Bd -literal -offset indent
|
|
$ kyua debug kernel/fs:rmdir
|
|
Trying rmdir('foo')
|
|
Trying rmdir(NULL)
|
|
kernel/fs:rmdir -> failed: Invalid argument
|
|
.Ed
|
|
.Pp
|
|
Luckily, the offending test case was printing status lines as it
|
|
progressed, so we could see the last attempted call and we can know match
|
|
the failure message to the problem.

|
.Sh EXIT STATUS
|
|
The
|
|
.Nm
|
|
command returns 0 if the test case passes or 1 if the test case fails.
|
|
.Pp
|
|
Additional exit codes may be returned as described in
