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,
41 it refuses to work. See L</ENVIRONMENT> below.

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")) {

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.

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

456 foreach (keys %saved_hooks) {

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

528 OpenSSL::Test depends on some environment variables.
534 This environment variable is mandatory. C<setup> will check that it's
535 defined and that it's a directory that contains the file C<Configure>.
536 If this isn't so, C<setup> will C<BAIL_OUT>.
540 If defined, its value should be the directory where the openssl application
541 is located. Defaults to C<$TOP/apps> (adapted to the operating system).
545 If defined, its value should be the directory where the test applications
546 are located. Defaults to C<$TOP/test> (adapted to the operating system).
550 If defined, its value should be the directory where the log files are
551 located. Defaults to C<$TEST_D>.
555 If defined, it puts testing in a different mode, where a recipe with
556 failures will result in a C<BAIL_OUT> at the end of its run.
