OpenSSL::Test - a private extension of Test::More
=head1 SYNOPSIS
use OpenSSL::Test;
setup("my_test_name");
ok(run(app(["openssl", "version"])), "check for openssl presence");
indir "subdir" => sub {
ok(run(test(["sometest", "arg1"], stdout => "foo.txt")),
"run sometest with output to foo.txt");
};
=head1 DESCRIPTION
This module is a private extension of L<Test::More> for testing OpenSSL.
In addition to the Test::More functions, it also provides functions that
easily find the diverse programs within a OpenSSL build tree, as well as
some other useful functions.
This module I<depends> on the environment variables C<$TOP> or C<$SRCTOP>
and C<$BLDTOP>. Without one of the combinations it refuses to work.
See L</ENVIRONMENT> below.
With each test recipe, a parallel data directory with (almost) the same name
as the recipe is possible in the source directory tree. For example, for a
recipe C<$SRCTOP/test/recipes/99-foo.t>, there could be a directory
C<$SRCTOP/test/recipes/99-foo_data/>.

=head2 Main functions
The following functions are exported by default when using C<OpenSSL::Test>.
=cut
=over 4
=item B<setup "NAME">
C<setup> is used for initial setup, and it is mandatory that it's used.
If it's not used in a OpenSSL test recipe, the rest of the recipe will
most likely refuse to run.
C<setup> checks for environment variables (see L</ENVIRONMENT> below),
checks that C<$TOP/Configure> or C<$SRCTOP/Configure> exists, C<chdir>
into the results directory (defined by the C<$RESULT_D> environment
variable if defined, otherwise C<$BLDTOP/test> or C<$TOP/test>, whichever
is defined).
=back
=cut
sub setup {
my $old_test_name = $test_name;
$test_name = shift;
BAIL_OUT("setup() must receive a name") unless $test_name;
warn "setup() detected test name change. Innocuous, so we continue...\n"
if $old_test_name && $old_test_name ne $test_name;
return if $old_test_name;
BAIL_OUT("setup() needs \$TOP or \$SRCTOP and \$BLDTOP to be defined")
unless $ENV{TOP} || ($ENV{SRCTOP} && $ENV{BLDTOP});
BAIL_OUT("setup() found both \$TOP and \$SRCTOP or \$BLDTOP...")
if $ENV{TOP} && ($ENV{SRCTOP} || $ENV{BLDTOP});
__env();
BAIL_OUT("setup() expects the file Configure in the source top directory")
unless -f srctop_file("Configure");
__cwd($directories{RESULTS});
}
=over 4
=item B<indir "SUBDIR" =E<gt> sub BLOCK, OPTS>
C<indir> is used to run a part of the recipe in a different directory than
the one C<setup> moved into, usually a subdirectory, given by SUBDIR.
The part of the recipe that's run there is given by the codeblock BLOCK.
C<indir> takes some additional options OPTS that affect the subdirectory:
=over 4
=item B<create =E<gt> 0|1>
When set to 1 (or any value that perl preceives as true), the subdirectory
will be created if it doesn't already exist. This happens before BLOCK
is executed.
=item B<cleanup =E<gt> 0|1>
When set to 1 (or any value that perl preceives as true), the subdirectory
will be cleaned out and removed. This happens both before and after BLOCK
is executed.
=back
An example:
indir "foo" => sub {
ok(run(app(["openssl", "version"]), stdout => "foo.txt"));
if (ok(open(RESULT, "foo.txt"), "reading foo.txt")) {
my $line = <RESULT>;
close RESULT;
is($line, qr/^OpenSSL 1\./,
"check that we're using OpenSSL 1.x.x");
}
}, create => 1, cleanup => 1;
=back
=cut
sub indir {
my $subdir = shift;
my $codeblock = shift;
my %opts = @_;
my $reverse = __cwd($subdir,%opts);
BAIL_OUT("FAILURE: indir, \"$subdir\" wasn't possible to move into")
unless $reverse;
$codeblock->();
__cwd($reverse);
if ($opts{cleanup}) {
rmtree($subdir, { safe => 0 });
}
}
=over 4
=item B<app ARRAYREF, OPTS>
=item B<test ARRAYREF, OPTS>
Both of these functions take a reference to a list that is a command and
its arguments, and some additional options (described further on).
C<app> expects to find the given command (the first item in the given list
reference) as an executable in C<$BIN_D> (if defined, otherwise C<$TOP/apps>
or C<$BLDTOP/apps>).
C<test> expects to find the given command (the first item in the given list
reference) as an executable in C<$TEST_D> (if defined, otherwise C<$TOP/test>
or C<$BLDTOP/test>).
Both return a CODEREF to be used by C<run>, C<pipe> or C<cmdstr>.
The options that both C<app> and C<test> can take are in the form of hash
values:
=over 4
=item B<stdin =E<gt> PATH>
=item B<stdout =E<gt> PATH>
=item B<stderr =E<gt> PATH>
In all three cases, the corresponding standard input, output or error is
redirected from (for stdin) or to (for the others) a file given by the
string PATH, I<or>, if the value is C<undef>, C</dev/null> or similar.
=back
=item B<perlapp ARRAYREF, OPTS>
=item B<perltest ARRAYREF, OPTS>
Both these functions function the same way as B<app> and B<test>, except
that they expect the command to be a perl script. Also, they support one
more option:
=over 4
=item B<interpreter_args =E<gt> ARRAYref>
The array reference is a set of arguments for perl rather than the script.
Take care so that none of them can be seen as a script! Flags and their
eventual arguments only!
=back
An example:
ok(run(perlapp(["foo.pl", "arg1"],
interpreter_args => [ "-I", srctop_dir("test") ])));
=back

}
=over 4
=item B<run CODEREF, OPTS>
This CODEREF is expected to be the value return by C<app> or C<test>,
anything else will most likely cause an error unless you know what you're
doing.
C<run> executes the command returned by CODEREF and return either the
resulting output (if the option C<capture> is set true) or a boolean indicating
if the command succeeded or not.
The options that C<run> can take are in the form of hash values:
=over 4
=item B<capture =E<gt> 0|1>
If true, the command will be executed with a perl backtick, and C<run> will
return the resulting output as an array of lines. If false or not given,
the command will be executed with C<system()>, and C<run> will return 1 if
the command was successful or 0 if it wasn't.
=back
For further discussion on what is considered a successful command or not, see
the function C<with> further down.

=item B<display =E<gt> 0|1>
When set to 0, the returned string will be with all decorations, such as a
possible redirect of stderr to the null device. This is suitable if the
string is to be used directly in a recipe.
When set to 1, the returned string will be without extra decorations. This
is suitable for display if that is desired (doesn't confuse people with all
internal stuff), or if it's used to pass a command down to a subprocess.

LIST is a list of strings that are going to be used as arguments for a

OpenSSL::Test depends on some environment variables.
=over 4

This environment variable is mandatory. C<setup> will check that it's
defined and that it's a directory that contains the file C<Configure>.
If this isn't so, C<setup> will C<BAIL_OUT>.
=item B<BIN_D>
If defined, its value should be the directory where the openssl application
is located. Defaults to C<$TOP/apps> (adapted to the operating system).
=item B<TEST_D>
If defined, its value should be the directory where the test applications
are located. Defaults to C<$TOP/test> (adapted to the operating system).
=item B<STOPTEST>
If defined, it puts testing in a different mode, where a recipe with
failures will result in a C<BAIL_OUT> at the end of its run.
