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

42 and C<$BLDTOP>. Without one of the combinations it refuses to work.

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

128 BAIL_OUT("setup() needs \$TOP or \$SRCTOP and \$BLDTOP to be defined")

130 BAIL_OUT("setup() found both \$TOP and \$SRCTOP or \$BLDTOP...")
131 if $ENV{TOP} && ($ENV{SRCTOP} || $ENV{BLDTOP});

140 # Loop in case we're on a platform with more than one file generation
141 1 while unlink(__test_log());
146 =item B<indir "SUBDIR" =E<gt> sub BLOCK, OPTS>
148 C<indir> is used to run a part of the recipe in a different directory than
149 the one C<setup> moved into, usually a subdirectory, given by SUBDIR.
150 The part of the recipe that's run there is given by the codeblock BLOCK.
152 C<indir> takes some additional options OPTS that affect the subdirectory:
156 =item B<create =E<gt> 0|1>
158 When set to 1 (or any value that perl preceives as true), the subdirectory
159 will be created if it doesn't already exist. This happens before BLOCK
162 =item B<cleanup =E<gt> 0|1>
164 When set to 1 (or any value that perl preceives as true), the subdirectory
165 will be cleaned out and removed. This happens both before and after BLOCK
173 ok(run(app(["openssl", "version"]), stdout => "foo.txt"));
174 if (ok(open(RESULT, "foo.txt"), "reading foo.txt")) {
177 is($line, qr/^OpenSSL 1\./,

200 rmtree($subdir, { safe => 0 });
206 =item B<app ARRAYREF, OPTS>
208 =item B<test ARRAYREF, OPTS>
210 Both of these functions take a reference to a list that is a command and
211 its arguments, and some additional options (described further on).
213 C<app> expects to find the given command (the first item in the given list
214 reference) as an executable in C<$BIN_D> (if defined, otherwise C<$TOP/apps>
217 C<test> expects to find the given command (the first item in the given list
218 reference) as an executable in C<$TEST_D> (if defined, otherwise C<$TOP/test>
221 Both return a CODEREF to be used by C<run>, C<pipe> or C<cmdstr>.
223 The options that both C<app> and C<test> can take are in the form of hash
228 =item B<stdin =E<gt> PATH>
230 =item B<stdout =E<gt> PATH>
232 =item B<stderr =E<gt> PATH>
234 In all three cases, the corresponding standard input, output or error is
235 redirected from (for stdin) or to (for the others) a file given by the
236 string PATH, I<or>, if the value is C<undef>, C</dev/null> or similar.
240 =item B<perlapp ARRAYREF, OPTS>
242 =item B<perltest ARRAYREF, OPTS>
244 Both these functions function the same way as B<app> and B<test>, except
245 that they expect the command to be a perl script.

281 =item B<run CODEREF, OPTS>
283 This CODEREF is expected to be the value return by C<app> or C<test>,
284 anything else will most likely cause an error unless you know what you're
287 C<run> executes the command returned by CODEREF and return either the
288 resulting output (if the option C<capture> is set true) or a boolean indicating
289 if the command succeeded or not.
291 The options that C<run> can take are in the form of hash values:
295 =item B<capture =E<gt> 0|1>
297 If true, the command will be executed with a perl backtick, and C<run> will
298 return the resulting output as an array of lines. If false or not given,
299 the command will be executed with C<system()>, and C<run> will return 1 if
300 the command was successful or 0 if it wasn't.
304 For further discussion on what is considered a successful command or not, see
305 the function C<with> further down.

455 LIST is a list of CODEREFs returned by C<app> or C<test>, from which C<pipe>
456 creates a new command composed of all the given commands put together in a
