For instance, root (or super-user or Administrator) may always be able to read files no matter the permissions. .PP Some attributes don't make sense outside of Unix, either, so some tests automatically skip if they think they won't work on the platform. If you have a way to make these functions work on Windows, for instance, please send me a patch. :) \s-1IF\s0 you want to pretend to be Windows on a non-Windows machine (for instance, to test \f(CW\*(C`skip()\*(C'\fR), you can set the \f(CW\*(C`PRETEND_TO_BE_WINDOWS\*(C'\fR environment variable. .PP The optional \s-1NAME\s0 parameter for every function allows you to specify a name for the test.

Besides memory consumption, test diagnostics for failing tests might be difficult to decipher. However, for short files this works very well. .Sp Because the entire contents are treated as one large string, you can make a pattern that tests multiple lines. Don't forget that you may need to use the /s modifier for such patterns: .Sp .Vb 2 \& # make sure file has one or more paragraphs with CSS class X \& file_contains_like($html_file, qr{<p class="X">.*?</p>}s); .Ve .Sp Contrariwise, if you need to match at the beginning or end of a line inside the file, use the /m modifier: .Sp .Vb 2 \& # make sure file has a setting for foo \& file_contains_like($config_file, qr/^ foo \es* = \es* \ew+ $/mx); .Ve .Sp If you want to test your file contents against multiple patterns, but don't want to have the file read in repeatedly, you can pass an arrayref of patterns instead of a single pattern, like so: .Sp .Vb 7 \& # make sure our template has rendered correctly \& file_contains_like($template_out, \& [ \& qr/^ $title_line $/mx, \& map { qr/^ $_ $/mx } @chapter_headings, \& qr/^ $footer_line $/mx, \& ]); .Ve .Sp Please note that if you do this, and your file does not exist or is not readable, you'll only get one test failure instead of a failure for each pattern. This could cause your test plan to be off, although you may not care at that point because your test failed anyway. If you do care, either skip the test plan altogether by employing Test::More's \f(CW\*(C`done_testing()\*(C'\fR function, or use \&\*(L"file_readable_ok\*(R" in conjunction with a \f(CW\*(C`SKIP\*(C'\fR block. .Sp Contributed by Buddy Burden \f(CW\*(C`<barefoot@cpan.org>\*(C'\fR. .IP "file_contains_unlike ( \s-1FILENAME, PATTERN\s0 [, \s-1NAME \s0] )" 4 .IX Item "file_contains_unlike ( FILENAME, PATTERN [, NAME ] )" Ok if the file exists and its contents (as one big string) do \fBnot\fR match \s-1PATTERN,\s0 not ok if the file does not exist, is not readable, or exists but matches \s-1PATTERN.\s0 .Sp All notes and caveats for \*(L"file_contains_like\*(R" apply to this function as well. .Sp Contributed by Buddy Burden \f(CW\*(C`<barefoot@cpan.org>\*(C'\fR. .IP "file_contains_utf8_like ( \s-1FILENAME, PATTERN\s0 [, \s-1NAME \s0] )" 4 .IX Item "file_contains_utf8_like ( FILENAME, PATTERN [, NAME ] )" The same as \f(CW\*(C`file_contains_like\*(C'\fR, except the file is opened as \s-1UTF\-8.\s0 .IP "file_contains_utf8_unlike ( \s-1FILENAME, PATTERN\s0 [, \s-1NAME \s0] )" 4 .IX Item "file_contains_utf8_unlike ( FILENAME, PATTERN [, NAME ] )" The same as \f(CW\*(C`file_contains_unlike\*(C'\fR, except the file is opened as \s-1UTF\-8.\s0 .IP "file_contains_encoded_like ( \s-1FILENAME, ENCODING, PATTERN\s0 [, \s-1NAME \s0] )" 4 .IX Item "file_contains_encoded_like ( FILENAME, ENCODING, PATTERN [, NAME ] )" The same as \f(CW\*(C`file_contains_like\*(C'\fR, except the file is opened with \s-1ENCODING\s0 .IP "file_contains_encoded_unlike ( \s-1FILENAME, ENCODING, PATTERN\s0 [, \s-1NAME \s0] )" 4 .IX Item "file_contains_encoded_unlike ( FILENAME, ENCODING, PATTERN [, NAME ] )" The same as \f(CW\*(C`file_contains_unlike\*(C'\fR, except the file is opened with \s-1ENCODING.\s0 .IP "file_readable_ok( \s-1FILENAME\s0 [, \s-1NAME \s0] )" 4 .IX Item "file_readable_ok( FILENAME [, NAME ] )" Ok if the file exists and is readable, not ok if the file does not exist or is not readable. .IP "file_not_readable_ok( \s-1FILENAME\s0 [, \s-1NAME \s0] )" 4 .IX Item "file_not_readable_ok( FILENAME [, NAME ] )" Ok if the file exists and is not readable, not ok if the file does not exist or is readable. .IP "file_writeable_ok( \s-1FILENAME\s0 [, \s-1NAME \s0] )" 4 .IX Item "file_writeable_ok( FILENAME [, NAME ] )" Ok if the file exists and is writeable, not ok if the file does not exist or is not writeable. .IP "file_not_writeable_ok( \s-1FILENAME\s0 [, \s-1NAME \s0] )" 4 .IX Item "file_not_writeable_ok( FILENAME [, NAME ] )" Ok if the file exists and is not writeable, not ok if the file does not exist or is writeable. .IP "file_executable_ok( \s-1FILENAME\s0 [, \s-1NAME \s0] )" 4 .IX Item "file_executable_ok( FILENAME [, NAME ] )" Ok if the file exists and is executable, not ok if the file does not exist or is not executable. .Sp This test automatically skips if it thinks it is on a Windows platform. .IP "file_not_executable_ok( \s-1FILENAME\s0 [, \s-1NAME \s0] )" 4 .IX Item "file_not_executable_ok( FILENAME [, NAME ] )" Ok if the file exists and is not executable, not ok if the file does not exist or is executable. .Sp This test automatically skips if it thinks it is on a Windows platform. .IP "file_mode_is( \s-1FILENAME, MODE\s0 [, \s-1NAME \s0] )" 4 .IX Item "file_mode_is( FILENAME, MODE [, NAME ] )" Ok if the file exists and the mode matches, not ok if the file does not exist or the mode does not match. .Sp This test automatically skips if it thinks it is on a Windows platform. .Sp Contributed by Shawn Sorichetti \f(CW\*(C`<ssoriche@coloredblocks.net>\*(C'\fR .IP "file_mode_isnt( \s-1FILENAME, MODE\s0 [, \s-1NAME \s0] )" 4 .IX Item "file_mode_isnt( FILENAME, MODE [, NAME ] )" Ok if the file exists and mode does not match, not ok if the file does not exist or mode does match. .Sp This test automatically skips if it thinks it is on a Windows platform. .Sp Contributed by Shawn Sorichetti \f(CW\*(C`<ssoriche@coloredblocks.net>\*(C'\fR .IP "file_mode_has( \s-1FILENAME, MODE\s0 [, \s-1NAME \s0] )" 4 .IX Item "file_mode_has( FILENAME, MODE [, NAME ] )" Ok if the file exists and has all the bits in mode turned on, not ok if the file does not exist or the mode does not match.
