51 This module is a private extension of L<Test::More> for testing OpenSSL.
52 In addition to the Test::More functions, it also provides functions that
53 easily find the diverse programs within a OpenSSL build tree, as well as
54 some other useful functions.
56 This module I<depends> on the environment variables C<$TOP> or C<$SRCTOP>
57 and C<$BLDTOP>. Without one of the combinations it refuses to work.
58 See L</ENVIRONMENT> below.
60 With each test recipe, a parallel data directory with (almost) the same name
61 as the recipe is possible in the source directory tree. For example, for a
62 recipe C<$SRCTOP/test/recipes/99-foo.t>, there could be a directory
63 C<$SRCTOP/test/recipes/99-foo_data/>.

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-runs> or C<$TOP/test-runs>,
130 whichever is defined).

149 BAIL_OUT("setup() found both \$TOP and \$SRCTOP or \$BLDTOP...")

154 BAIL_OUT("setup() expects the file Configure in the source top directory")
155 unless -f srctop_file("Configure");
157 note "The results of this test will end up in $directories{RESULTS}"
160 __cwd($directories{RESULTS});
165 =item B<indir "SUBDIR" =E<gt> sub BLOCK, OPTS>
167 C<indir> is used to run a part of the recipe in a different directory than
168 the one C<setup> moved into, usually a subdirectory, given by SUBDIR.
169 The part of the recipe that's run there is given by the codeblock BLOCK.
171 C<indir> takes some additional options OPTS that affect the subdirectory:
175 =item B<create =E<gt> 0|1>
177 When set to 1 (or any value that perl perceives as true), the subdirectory
178 will be created if it doesn't already exist. This happens before BLOCK
186 ok(run(app(["openssl", "version"]), stdout => "foo.txt"));
187 if (ok(open(RESULT, "foo.txt"), "reading foo.txt")) {
190 is($line, qr/^OpenSSL 1\./,
191 "check that we're using OpenSSL 1.x.x");
201 my $codeblock = shift;
204 my $reverse = __cwd($subdir,%opts);
205 BAIL_OUT("FAILURE: indir, \"$subdir\" wasn't possible to move into")
215 =item B<cmd ARRAYREF, OPTS>
217 This functions build up a platform dependent command based on the
218 input. It takes a reference to a list that is the executable or
219 script and its arguments, and some additional options (described
220 further on). Where necessary, the command will be wrapped in a
221 suitable environment to make sure the correct shared libraries are
222 used (currently only on Unix).
224 It returns a CODEREF to be used by C<run>, C<pipe> or C<cmdstr>.
226 The options that C<cmd> (as well as its derivatives described below) can take
227 are in the form of hash values:
231 =item B<stdin =E<gt> PATH>
233 =item B<stdout =E<gt> PATH>
235 =item B<stderr =E<gt> PATH>
237 In all three cases, the corresponding standard input, output or error is
238 redirected from (for stdin) or to (for the others) a file given by the
239 string PATH, I<or>, if the value is C<undef>, C</dev/null> or similar.
243 =item B<app ARRAYREF, OPTS>
245 =item B<test ARRAYREF, OPTS>
247 Both of these are specific applications of C<cmd>, with just a couple
250 C<app> expects to find the given command (the first item in the given list
251 reference) as an executable in C<$BIN_D> (if defined, otherwise C<$TOP/apps>
254 C<test> expects to find the given command (the first item in the given list
255 reference) as an executable in C<$TEST_D> (if defined, otherwise C<$TOP/test>
258 Also, for both C<app> and C<test>, the command may be prefixed with
259 the content of the environment variable C<$EXE_SHELL>, which is useful
260 in case OpenSSL has been cross compiled.
262 =item B<perlapp ARRAYREF, OPTS>
264 =item B<perltest ARRAYREF, OPTS>
266 These are also specific applications of C<cmd>, where the interpreter
267 is predefined to be C<perl>, and they expect the script to be
268 interpreted to reside in the same location as C<app> and C<test>.
270 C<perlapp> and C<perltest> will also take the following option:
274 =item B<interpreter_args =E<gt> ARRAYref>
276 The array reference is a set of arguments for the interpreter rather
277 than the script. Take care so that none of them can be seen as a
278 script! Flags and their eventual arguments only!
284 ok(run(perlapp(["foo.pl", "arg1"],
285 interpreter_args => [ "-I", srctop_dir("test") ])));
291 One might wonder over the complexity of C<apps>, C<fuzz>, C<test>, ...
292 with all the lazy evaluations and all that. The reason for this is that
293 we want to make sure the directory in which those programs are found are
294 correct at the time these commands are used. Consider the following code
297 my $cmd = app(["openssl", ...]);
300 ok(run($cmd), "Testing foo")
303 If there wasn't this lazy evaluation, the directory where C<openssl> is
304 found would be incorrect at the time C<run> is called, because it was
305 calculated before we moved into the directory "foo".

381 return cmd([ @interpreter, @interpreter_args,
382 @prog, @cmdargs ], %opts) -> (shift);
388 =item B<run CODEREF, OPTS>
390 CODEREF is expected to be the value return by C<cmd> or any of its
391 derivatives, anything else will most likely cause an error unless you
392 know what you're doing.
394 C<run> executes the command returned by CODEREF and return either the
395 resulting standard output (if the option C<capture> is set true) or a boolean
396 indicating if the command succeeded or not.
398 The options that C<run> can take are in the form of hash values:
402 =item B<capture =E<gt> 0|1>
404 If true, the command will be executed with a perl backtick,
405 and C<run> will return the resulting standard output as an array of lines.
406 If false or not given, the command will be executed with C<system()>,
407 and C<run> will return 1 if the command was successful or 0 if it wasn't.
409 =item B<prefix =E<gt> EXPR>
411 If specified, EXPR will be used as a string to prefix the output from the
412 command. This is useful if the output contains lines starting with C<ok >
413 or C<not ok > that can disturb Test::Harness.
415 =item B<statusvar =E<gt> VARREF>
417 If used, B<VARREF> must be a reference to a scalar variable. It will be
418 assigned a boolean indicating if the command succeeded or not. This is
419 particularly useful together with B<capture>.
423 Usually 1 indicates that the command was successful and 0 indicates failure.
424 For further discussion on what is considered a successful command or not, see
425 the function C<with> further down.

926 OpenSSL::Test depends on some environment variables.
932 This environment variable is mandatory. C<setup> will check that it's
933 defined and that it's a directory that contains the file C<Configure>.
934 If this isn't so, C<setup> will C<BAIL_OUT>.
938 If defined, its value should be the directory where the openssl application
939 is located. Defaults to C<$TOP/apps> (adapted to the operating system).
943 If defined, its value should be the directory where the test applications
944 are located. Defaults to C<$TOP/test> (adapted to the operating system).
948 If defined, it puts testing in a different mode, where a recipe with
949 failures will result in a C<BAIL_OUT> at the end of its run.
953 If defined it indicates that the FIPS provider is being tested. Tests may use
954 B<ok_nofips>, B<is_nofips> and B<isnt_nofips> to invert test results
955 i.e. Some tests may only work in non FIPS mode.
