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

110 =head2 Main functions
112 The following functions are exported by default when using C<OpenSSL::Test>.
118 =item B<setup "NAME">
120 C<setup> is used for initial setup, and it is mandatory that it's used.
121 If it's not used in a OpenSSL test recipe, the rest of the recipe will
122 most likely refuse to run.
124 C<setup> checks for environment variables (see L</ENVIRONMENT> below),
125 checks that C<$TOP/Configure> or C<$SRCTOP/Configure> exists, C<chdir>
126 into the results directory (defined by the C<$RESULT_D> environment
127 variable if defined, otherwise C<$BLDTOP/test-runs> or C<$TOP/test-runs>,
128 whichever is defined).
135 my $old_test_name = $test_name;
139 BAIL_OUT("setup() must receive a name") unless $test_name;
140 warn "setup() detected test name change. Innocuous, so we continue...\n"
141 if $old_test_name && $old_test_name ne $test_name;
143 return if $old_test_name;
145 BAIL_OUT("setup() needs \$TOP or \$SRCTOP and \$BLDTOP to be defined")
146 unless $ENV{TOP} || ($ENV{SRCTOP} && $ENV{BLDTOP});
147 BAIL_OUT("setup() found both \$TOP and \$SRCTOP or \$BLDTOP...")
148 if $ENV{TOP} && ($ENV{SRCTOP} || $ENV{BLDTOP});
152 BAIL_OUT("setup() expects the file Configure in the source top directory")
153 unless -f srctop_file("Configure");
155 note "The results of this test will end up in $directories{RESULTS}"
158 __cwd($directories{RESULTS});
163 =item B<indir "SUBDIR" =E<gt> sub BLOCK, OPTS>
165 C<indir> is used to run a part of the recipe in a different directory than
166 the one C<setup> moved into, usually a subdirectory, given by SUBDIR.
167 The part of the recipe that's run there is given by the codeblock BLOCK.
169 C<indir> takes some additional options OPTS that affect the subdirectory:
173 =item B<create =E<gt> 0|1>
175 When set to 1 (or any value that perl perceives as true), the subdirectory
176 will be created if it doesn't already exist. This happens before BLOCK
184 ok(run(app(["openssl", "version"]), stdout => "foo.txt"));
185 if (ok(open(RESULT, "foo.txt"), "reading foo.txt")) {
188 is($line, qr/^OpenSSL 1\./,
189 "check that we're using OpenSSL 1.x.x");
199 my $codeblock = shift;
202 my $reverse = __cwd($subdir,%opts);
203 BAIL_OUT("FAILURE: indir, \"$subdir\" wasn't possible to move into")
213 =item B<cmd ARRAYREF, OPTS>
215 This functions build up a platform dependent command based on the
216 input. It takes a reference to a list that is the executable or
217 script and its arguments, and some additional options (described
218 further on). Where necessary, the command will be wrapped in a
219 suitable environment to make sure the correct shared libraries are
220 used (currently only on Unix).
222 It returns a CODEREF to be used by C<run>, C<pipe> or C<cmdstr>.
224 The options that C<cmd> (as well as its derivatives described below) can take
225 are in the form of hash values:
229 =item B<stdin =E<gt> PATH>
231 =item B<stdout =E<gt> PATH>
233 =item B<stderr =E<gt> PATH>
235 In all three cases, the corresponding standard input, output or error is
236 redirected from (for stdin) or to (for the others) a file given by the
237 string PATH, I<or>, if the value is C<undef>, C</dev/null> or similar.
241 =item B<app ARRAYREF, OPTS>
243 =item B<test ARRAYREF, OPTS>
245 Both of these are specific applications of C<cmd>, with just a couple
248 C<app> expects to find the given command (the first item in the given list
249 reference) as an executable in C<$BIN_D> (if defined, otherwise C<$TOP/apps>
252 C<test> expects to find the given command (the first item in the given list
253 reference) as an executable in C<$TEST_D> (if defined, otherwise C<$TOP/test>
256 Also, for both C<app> and C<test>, the command may be prefixed with
257 the content of the environment variable C<$EXE_SHELL>, which is useful
258 in case OpenSSL has been cross compiled.
260 =item B<perlapp ARRAYREF, OPTS>
262 =item B<perltest ARRAYREF, OPTS>
264 These are also specific applications of C<cmd>, where the interpreter
265 is predefined to be C<perl>, and they expect the script to be
266 interpreted to reside in the same location as C<app> and C<test>.
268 C<perlapp> and C<perltest> will also take the following option:
272 =item B<interpreter_args =E<gt> ARRAYref>
274 The array reference is a set of arguments for the interpreter rather
275 than the script. Take care so that none of them can be seen as a
276 script! Flags and their eventual arguments only!
282 ok(run(perlapp(["foo.pl", "arg1"],
283 interpreter_args => [ "-I", srctop_dir("test") ])));
289 One might wonder over the complexity of C<apps>, C<fuzz>, C<test>, ...
290 with all the lazy evaluations and all that. The reason for this is that
291 we want to make sure the directory in which those programs are found are
292 correct at the time these commands are used. Consider the following code
295 my $cmd = app(["openssl", ...]);
298 ok(run($cmd), "Testing foo")
301 If there wasn't this lazy evaluation, the directory where C<openssl> is
302 found would be incorrect at the time C<run> is called, because it was
303 calculated before we moved into the directory "foo".

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

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