35 This module is a private extension of L<Test::More> for testing OpenSSL.
36 In addition to the Test::More functions, it also provides functions that
37 easily find the diverse programs within a OpenSSL build tree, as well as
38 some other useful functions.
40 This module I<depends> on the environment variable C<$TOP>. Without it,

102 =item B<setup "NAME">
104 C<setup> is used for initial setup, and it is mandatory that it's used.
105 If it's not used in a OpenSSL test recipe, the rest of the recipe will
106 most likely refuse to run.
108 C<setup> checks for environment variables (see L</ENVIRONMENT> below),
109 check that C<$TOP/Configure> exists, C<chdir> into the results directory
110 (defined by the C<$RESULT_D> environment variable if defined, otherwise
111 C<$TEST_D> if defined, otherwise C<$TOP/test>).

131 1 while unlink(__test_log());
136 =item B<indir "SUBDIR" =E<gt> sub BLOCK, OPTS>
138 C<indir> is used to run a part of the recipe in a different directory than
139 the one C<setup> moved into, usually a subdirectory, given by SUBDIR.
140 The part of the recipe that's run there is given by the codeblock BLOCK.
142 C<indir> takes some additional options OPTS that affect the subdirectory:
146 =item B<create =E<gt> 0|1>
148 When set to 1 (or any value that perl preceives as true), the subdirectory
149 will be created if it doesn't already exist. This happens before BLOCK
152 =item B<cleanup =E<gt> 0|1>
154 When set to 1 (or any value that perl preceives as true), the subdirectory
155 will be cleaned out and removed. This happens both before and after BLOCK
163 ok(run(app(["openssl", "version"]), stdout => "foo.txt"));
164 if (ok(open(RESULT, "foo.txt"), "reading foo.txt")) {

190 remove_tree($subdir, { safe => 0 });
196 =item B<app ARRAYREF, OPTS>
198 =item B<test ARRAYREF, OPTS>
200 Both of these functions take a reference to a list that is a command and
201 its arguments, and some additional options (described further on).
203 C<app> expects to find the given command (the first item in the given list
204 reference) as an executable in C<$BIN_D> (if defined, otherwise C<$TOP/apps>).
206 C<test> expects to find the given command (the first item in the given list
207 reference) as an executable in C<$TEST_D> (if defined, otherwise C<$TOP/test>).
209 Both return a CODEREF to be used by C<run>, C<pipe> or C<cmdstr>.
211 The options that both C<app> and C<test> can take are in the form of hash
216 =item B<stdin =E<gt> PATH>
218 =item B<stdout =E<gt> PATH>
220 =item B<stderr =E<gt> PATH>
222 In all three cases, the corresponding standard input, output or error is
223 redirected from (for stdin) or to (for the others) a file given by the
224 string PATH, I<or>, if the value is C<undef>, C</dev/null> or similar.

243 return __build_cmd($num, \&__test_file, $cmd, %opts); }
248 =item B<run CODEREF, OPTS>
250 This CODEREF is expected to be the value return by C<app> or C<test>,
251 anything else will most likely cause an error unless you know what you're
254 C<run> executes the command returned by CODEREF and return either the
255 resulting output (if the option C<capture> is set true) or a boolean indicating
256 if the command succeeded or not.
258 The options that C<run> can take are in the form of hash values:
262 =item B<capture =E<gt> 0|1>
264 If true, the command will be executed with a perl backtick, and C<run> will
265 return the resulting output as an array of lines. If false or not given,
266 the command will be executed with C<system()>, and C<run> will return 1 if
267 the command was successful or 0 if it wasn't.
271 For further discussion on what is considered a successful command or not, see
272 the function C<with> further down.

348 =item B<top_dir LIST>
350 LIST is a list of directories that make up a path from the top of the OpenSSL
351 source directory (as indicated by the environment variable C<$TOP>).
352 C<top_dir> returns the resulting directory as a string, adapted to the local
360 return __top_file(@_, ""); # This caters for operating systems that have
361 # a very distinct syntax for directories.
366 =item B<top_file LIST, FILENAME>
368 LIST is a list of directories that make up a path from the top of the OpenSSL
369 source directory (as indicated by the environment variable C<$TOP>) and
370 FILENAME is the name of a file located in that directory path.
371 C<top_file> returns the resulting file path as a string, adapted to the local
379 return __top_file(@_);
386 LIST is a list of CODEREFs returned by C<app> or C<test>, from which C<pipe>
387 creates a new command composed of all the given commands put together in a
388 pipe. C<pipe> returns a new CODEREF in the same manner as C<app> or C<test>,
389 to be passed to C<run> for execution.
404 my ($c, $dc, @el) = $_->(++$counter);
422 =item B<with HASHREF, CODEREF>
424 C<with> will temporarly install hooks given by the HASHREF and then execute
425 the given CODEREF. Hooks are usually expected to have a coderef as value.
427 The currently available hoosk are:
431 =item B<exit_checker =E<gt> CODEREF>
433 This hook is executed after C<run> has performed its given command. The
434 CODEREF receives the exit code as only argument and is expected to return
435 1 (if the exit code indicated success) or 0 (if the exit code indicated

475 my ($cmd, $display_cmd, %errlogs) = shift->(0);
482 =item B<quotify LIST>
484 LIST is a list of strings that are going to be used as arguments for a
485 command, and makes sure to inject quotes and escapes as necessary depending
486 on the content of each string.
488 This can also be used to put quotes around the executable of a command.

530 OpenSSL::Test depends on some environment variables.
536 This environment variable is mandatory. C<setup> will check that it's
537 defined and that it's a directory that contains the file C<Configure>.
538 If this isn't so, C<setup> will C<BAIL_OUT>.
542 If defined, its value should be the directory where the openssl application
543 is located. Defaults to C<$TOP/apps> (adapted to the operating system).
547 If defined, its value should be the directory where the test applications
548 are located. Defaults to C<$TOP/test> (adapted to the operating system).
552 If defined, its value should be the directory where the log files are
553 located. Defaults to C<$TEST_D>.
557 If defined, it puts testing in a different mode, where a recipe with
558 failures will result in a C<BAIL_OUT> at the end of its run.
