To do so, a few dependencies have been imported: * external/bsd/lutok * external/mit/lua * external/public-domain/sqlite * external/public-domain/xz The Kyua framework is the new generation of ATF (Automated Test Framework), it is composed of: * external/bsd/atf * external/bsd/kyua-atf-compat * external/bsd/kyua-cli * external/bsd/kyua-tester * tests Kyua/ATF being written in C++, it depends on libstdc++ which is provided by GCC. As this is not part of the sources, Kyua is only compiled when the native GCC utils are installed. To install Kyua do the following: * In a cross-build enviromnent, add the following to the build.sh commandline: -V MKBINUTILS=yes -V MKGCCCMDS=yes WARNING: At this point the import is still experimental, and not supported on native builds (a.k.a make build).

.Os
|
|
.Sh NAME
|
|
.Nm debug
|
|
.Nd Executes a single test case with facilities for debugging
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl -build-root Ar path
|
|
.Op Fl -kyuafile Ar file
|
|
.Op Fl -stdout Ar path
|
|
.Op Fl -stderr Ar path
|
|
.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 that matches a
|
|
single test case; see
|
|
.Xr kyua-test-filters 7 .
|
|
The test case is executed and its result is printed as the last line of the
|
|
output of the tool.
|
|
.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 arbitraty 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
|
|
.Xr kyua-build-root 7
|
|
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 that redirects the output to 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 that redirects the output to 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
|
|
.Xr kyua 1 .
