114 The following functions are exported by default when using C<OpenSSL::Test>.
120 =item B<setup "NAME">
122 C<setup> is used for initial setup, and it is mandatory that it's used.
123 If it's not used in a OpenSSL test recipe, the rest of the recipe will
124 most likely refuse to run.
126 C<setup> checks for environment variables (see L</ENVIRONMENT> below),
127 checks that C<$TOP/Configure> or C<$SRCTOP/Configure> exists, C<chdir>
128 into the results directory (defined by the C<$RESULT_D> environment
129 variable if defined, otherwise C<$BLDTOP/test> or C<$TOP/test>, whichever

154 unless -f srctop_file("Configure");
156 __cwd($directories{RESULTS});
161 =item B<indir "SUBDIR" =E<gt> sub BLOCK, OPTS>
163 C<indir> is used to run a part of the recipe in a different directory than
164 the one C<setup> moved into, usually a subdirectory, given by SUBDIR.
165 The part of the recipe that's run there is given by the codeblock BLOCK.
167 C<indir> takes some additional options OPTS that affect the subdirectory:
171 =item B<create =E<gt> 0|1>
173 When set to 1 (or any value that perl preceives as true), the subdirectory
174 will be created if it doesn't already exist. This happens before BLOCK
177 =item B<cleanup =E<gt> 0|1>
179 When set to 1 (or any value that perl preceives as true), the subdirectory
180 will be cleaned out and removed. This happens both before and after BLOCK
188 ok(run(app(["openssl", "version"]), stdout => "foo.txt"));
189 if (ok(open(RESULT, "foo.txt"), "reading foo.txt")) {
192 is($line, qr/^OpenSSL 1\./,
193 "check that we're using OpenSSL 1.x.x");
195 }, create => 1, cleanup => 1;

207 BAIL_OUT("FAILURE: indir, \"$subdir\" wasn't possible to move into")
214 if ($opts{cleanup}) {
215 rmtree($subdir, { safe => 0 });
221 =item B<cmd ARRAYREF, OPTS>
223 This functions build up a platform dependent command based on the
224 input. It takes a reference to a list that is the executable or
225 script and its arguments, and some additional options (described
228 It returns a CODEREF to be used by C<run>, C<pipe> or C<cmdstr>.
230 The options that C<cmd> can take are in the form of hash values:
234 =item B<stdin =E<gt> PATH>
236 =item B<stdout =E<gt> PATH>
238 =item B<stderr =E<gt> PATH>
240 In all three cases, the corresponding standard input, output or error is
241 redirected from (for stdin) or to (for the others) a file given by the
242 string PATH, I<or>, if the value is C<undef>, C</dev/null> or similar.
246 =item B<app ARRAYREF, OPTS>
248 =item B<test ARRAYREF, OPTS>
250 Both of these are specific applications of C<cmd>, with just a couple
253 C<app> expects to find the given command (the first item in the given list
254 reference) as an executable in C<$BIN_D> (if defined, otherwise C<$TOP/apps>
257 C<test> expects to find the given command (the first item in the given list
258 reference) as an executable in C<$TEST_D> (if defined, otherwise C<$TOP/test>
261 Also, for both C<app> and C<test>, the command may be prefixed with
262 the content of the environment variable C<$EXE_SHELL>, which is useful
263 in case OpenSSL has been cross compiled.
265 =item B<perlapp ARRAYREF, OPTS>
267 =item B<perltest ARRAYREF, OPTS>
269 These are also specific applications of C<cmd>, where the interpreter
270 is predefined to be C<perl>, and they expect the script to be
271 interpreted to reside in the same location as C<app> and C<test>.
273 C<perlapp> and C<perltest> will also take the following option:
277 =item B<interpreter_args =E<gt> ARRAYref>
279 The array reference is a set of arguments for the interpreter rather
280 than the script. Take care so that none of them can be seen as a
281 script! Flags and their eventual arguments only!
287 ok(run(perlapp(["foo.pl", "arg1"],
288 interpreter_args => [ "-I", srctop_dir("test") ])));
294 One might wonder over the complexity of C<apps>, C<fuzz>, C<test>, ...
295 with all the lazy evaluations and all that. The reason for this is that
296 we want to make sure the directory in which those programs are found are
297 correct at the time these commands are used. Consider the following code
300 my $cmd = app(["openssl", ...]);
303 ok(run($cmd), "Testing foo")
306 If there wasn't this lazy evaluation, the directory where C<openssl> is
307 found would be incorrect at the time C<run> is called, because it was
308 calculated before we moved into the directory "foo".

398 resulting output (if the option C<capture> is set true) or a boolean
399 indicating if the command succeeded or not.
401 The options that C<run> can take are in the form of hash values:
405 =item B<capture =E<gt> 0|1>
407 If true, the command will be executed with a perl backtick, and C<run> will
408 return the resulting output as an array of lines. If false or not given,
409 the command will be executed with C<system()>, and C<run> will return 1 if
410 the command was successful or 0 if it wasn't.
414 For further discussion on what is considered a successful command or not, see
