104 =head2 Main functions
106 The following functions are exported by default when using C<OpenSSL::Test>.
112 =item B<setup "NAME">
114 C<setup> is used for initial setup, and it is mandatory that it's used.
115 If it's not used in a OpenSSL test recipe, the rest of the recipe will
116 most likely refuse to run.
118 C<setup> checks for environment variables (see L</ENVIRONMENT> below),
119 checks that C<$TOP/Configure> or C<$SRCTOP/Configure> exists, C<chdir>
120 into the results directory (defined by the C<$RESULT_D> environment
121 variable if defined, otherwise C<$BLDTOP/test> or C<$TOP/test>, whichever
129 my $old_test_name = $test_name;

133 warn "setup() detected test name change. Innocuous, so we continue...\n"
134 if $old_test_name && $old_test_name ne $test_name;
136 return if $old_test_name;
138 BAIL_OUT("setup() needs \$TOP or \$SRCTOP and \$BLDTOP to be defined")
139 unless $ENV{TOP} || ($ENV{SRCTOP} && $ENV{BLDTOP});
140 BAIL_OUT("setup() found both \$TOP and \$SRCTOP or \$BLDTOP...")
141 if $ENV{TOP} && ($ENV{SRCTOP} || $ENV{BLDTOP});
145 BAIL_OUT("setup() expects the file Configure in the source top directory")
146 unless -f srctop_file("Configure");
148 __cwd($directories{RESULTS});
153 =item B<indir "SUBDIR" =E<gt> sub BLOCK, OPTS>
155 C<indir> is used to run a part of the recipe in a different directory than
156 the one C<setup> moved into, usually a subdirectory, given by SUBDIR.
157 The part of the recipe that's run there is given by the codeblock BLOCK.
159 C<indir> takes some additional options OPTS that affect the subdirectory:
163 =item B<create =E<gt> 0|1>
165 When set to 1 (or any value that perl preceives as true), the subdirectory
166 will be created if it doesn't already exist. This happens before BLOCK
169 =item B<cleanup =E<gt> 0|1>
171 When set to 1 (or any value that perl preceives as true), the subdirectory
172 will be cleaned out and removed. This happens both before and after BLOCK
180 ok(run(app(["openssl", "version"]), stdout => "foo.txt"));
181 if (ok(open(RESULT, "foo.txt"), "reading foo.txt")) {
184 is($line, qr/^OpenSSL 1\./,
185 "check that we're using OpenSSL 1.x.x");
187 }, create => 1, cleanup => 1;
195 my $codeblock = shift;
198 my $reverse = __cwd($subdir,%opts);
199 BAIL_OUT("FAILURE: indir, \"$subdir\" wasn't possible to move into")
206 if ($opts{cleanup}) {
207 rmtree($subdir, { safe => 0 });
213 =item B<app ARRAYREF, OPTS>
215 =item B<test ARRAYREF, OPTS>
217 Both of these functions take a reference to a list that is a command and
218 its arguments, and some additional options (described further on).
220 C<app> expects to find the given command (the first item in the given list
221 reference) as an executable in C<$BIN_D> (if defined, otherwise C<$TOP/apps>
224 C<test> expects to find the given command (the first item in the given list
225 reference) as an executable in C<$TEST_D> (if defined, otherwise C<$TOP/test>
228 Both return a CODEREF to be used by C<run>, C<pipe> or C<cmdstr>.
230 The options that both C<app> and C<test> can take are in the form of hash
235 =item B<stdin =E<gt> PATH>
237 =item B<stdout =E<gt> PATH>
239 =item B<stderr =E<gt> PATH>
241 In all three cases, the corresponding standard input, output or error is
242 redirected from (for stdin) or to (for the others) a file given by the
243 string PATH, I<or>, if the value is C<undef>, C</dev/null> or similar.
247 =item B<perlapp ARRAYREF, OPTS>
249 =item B<perltest ARRAYREF, OPTS>
251 Both these functions function the same way as B<app> and B<test>, except
252 that they expect the command to be a perl script. Also, they support one
257 =item B<interpreter_args =E<gt> ARRAYref>
259 The array reference is a set of arguments for perl rather than the script.
260 Take care so that none of them can be seen as a script! Flags and their
261 eventual arguments only!
267 ok(run(perlapp(["foo.pl", "arg1"],
268 interpreter_args => [ "-I", srctop_dir("test") ])));

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

414 return __bldtop_dir(@_); # This caters for operating systems that have
415 # a very distinct syntax for directories.

422 LIST is a list of directories that make up a path from the top of the OpenSSL
423 build directory (as indicated by the environment variable C<$TOP> or
424 C<$BLDTOP>) and FILENAME is the name of a file located in that directory path.
425 C<bldtop_file> returns the resulting file path as a string, adapted to the local
433 return __bldtop_file(@_);

441 source directory (as indicated by the environment variable C<$TOP> or

451 return __srctop_dir(@_); # This caters for operating systems that have
452 # a very distinct syntax for directories.

459 LIST is a list of directories that make up a path from the top of the OpenSSL
460 source directory (as indicated by the environment variable C<$TOP> or
461 C<$SRCTOP>) and FILENAME is the name of a file located in that directory path.
462 C<srctop_file> returns the resulting file path as a string, adapted to the local
470 return __srctop_file(@_);
477 LIST is a list of CODEREFs returned by C<app> or C<test>, from which C<pipe>
478 creates a new command composed of all the given commands put together in a
479 pipe. C<pipe> returns a new CODEREF in the same manner as C<app> or C<test>,

565 =item B<display =E<gt> 0|1>
567 When set to 0, the returned string will be with all decorations, such as a
568 possible redirect of stderr to the null device. This is suitable if the
569 string is to be used directly in a recipe.
571 When set to 1, the returned string will be without extra decorations. This
572 is suitable for display if that is desired (doesn't confuse people with all
573 internal stuff), or if it's used to pass a command down to a subprocess.
584 my ($cmd, $display_cmd) = shift->(0);
587 if ($opts{display}) {
596 =item B<quotify LIST>
598 LIST is a list of strings that are going to be used as arguments for a
599 command, and makes sure to inject quotes and escapes as necessary depending
600 on the content of each string.
602 This can also be used to put quotes around the executable of a command.

644 OpenSSL::Test depends on some environment variables.
650 This environment variable is mandatory. C<setup> will check that it's
651 defined and that it's a directory that contains the file C<Configure>.
652 If this isn't so, C<setup> will C<BAIL_OUT>.
656 If defined, its value should be the directory where the openssl application
657 is located. Defaults to C<$TOP/apps> (adapted to the operating system).
661 If defined, its value should be the directory where the test applications
662 are located. Defaults to C<$TOP/test> (adapted to the operating system).
666 If defined, it puts testing in a different mode, where a recipe with
