36 This module is a private extension of L<Test::More> for testing OpenSSL.
37 In addition to the Test::More functions, it also provides functions that
38 easily find the diverse programs within a OpenSSL build tree, as well as
39 some other useful functions.
41 This module I<depends> on the environment variables C<$TOP> or C<$SRCTOP>
42 and C<$BLDTOP>. Without one of the combinations it refuses to work.

109 C<setup> is used for initial setup, and it is mandatory that it's used.
110 If it's not used in a OpenSSL test recipe, the rest of the recipe will
111 most likely refuse to run.

150 C<indir> is used to run a part of the recipe in a different directory than
151 the one C<setup> moved into, usually a subdirectory, given by SUBDIR.
152 The part of the recipe that's run there is given by the codeblock BLOCK.
154 C<indir> takes some additional options OPTS that affect the subdirectory:
158 =item B<create =E<gt> 0|1>
160 When set to 1 (or any value that perl preceives as true), the subdirectory
161 will be created if it doesn't already exist. This happens before BLOCK
164 =item B<cleanup =E<gt> 0|1>
166 When set to 1 (or any value that perl preceives as true), the subdirectory
167 will be cleaned out and removed. This happens both before and after BLOCK

208 =item B<app ARRAYREF, OPTS>
210 =item B<test ARRAYREF, OPTS>
212 Both of these functions take a reference to a list that is a command and
213 its arguments, and some additional options (described further on).
215 C<app> expects to find the given command (the first item in the given list
216 reference) as an executable in C<$BIN_D> (if defined, otherwise C<$TOP/apps>
219 C<test> expects to find the given command (the first item in the given list
220 reference) as an executable in C<$TEST_D> (if defined, otherwise C<$TOP/test>
223 Both return a CODEREF to be used by C<run>, C<pipe> or C<cmdstr>.
225 The options that both C<app> and C<test> can take are in the form of hash
230 =item B<stdin =E<gt> PATH>
232 =item B<stdout =E<gt> PATH>
234 =item B<stderr =E<gt> PATH>
236 In all three cases, the corresponding standard input, output or error is
237 redirected from (for stdin) or to (for the others) a file given by the
238 string PATH, I<or>, if the value is C<undef>, C</dev/null> or similar.
242 =item B<perlapp ARRAYREF, OPTS>
244 =item B<perltest ARRAYREF, OPTS>
246 Both these functions function the same way as B<app> and B<test>, except
247 that they expect the command to be a perl script.

289 C<run> executes the command returned by CODEREF and return either the
290 resulting output (if the option C<capture> is set true) or a boolean indicating
291 if the command succeeded or not.
293 The options that C<run> can take are in the form of hash values:
297 =item B<capture =E<gt> 0|1>
299 If true, the command will be executed with a perl backtick, and C<run> will
300 return the resulting output as an array of lines. If false or not given,
301 the command will be executed with C<system()>, and C<run> will return 1 if
302 the command was successful or 0 if it wasn't.

441 return __srctop_file(@_);
448 LIST is a list of CODEREFs returned by C<app> or C<test>, from which C<pipe>
449 creates a new command composed of all the given commands put together in a

599 defined and that it's a directory that contains the file C<Configure>.
600 If this isn't so, C<setup> will C<BAIL_OUT>.
604 If defined, its value should be the directory where the openssl application

610 are located. Defaults to C<$TOP/test> (adapted to the operating system).
