Test::File::Contents(3pm)				User Contributed Perl Documentation				 Test::File::Contents(3pm)

Name
       Test::File::Contents - Test routines for examining the contents of files

Synopsis
	 use Test::File::Contents;

	 file_contents_eq	  $file,  $string,  $description;
	 file_contents_eq_or_diff $file,  $string,  $description;
	 file_contents_like	  $file,  qr/foo/,  $description;
	 file_md5sum_is 	  $file,  $md5sum,  $description;
	 files_eq		  $file1, $file2,   $description;
	 files_eq_or_diff	  $file1, $file2,   $description;

Description
       Got an app that generates files? Then you need to test those files to make sure that their contents are correct. This module makes that
       easy. Use its test functions to make sure that the contents of files are exactly what you expect them to be.

Interface
   Options
       These test functions take an optional hash reference of options which may include one or more of these options:

       "encoding"
	   The encoding in which the file is encoded. This will be used in an I/O layer to read in the file, so that it can be properly decoded to
	   Perl's internal representation. Examples include "UTF-8", "iso-8859-3", and "cp1252". See Encode::Supported for a list of supported
	   encodings. May also be specified as a layer, such as ":utf8" or ":raw". See perlio for a complete list of layers.

	   Note that it's important to specify the encoding if you have non-ASCII characters in your file. And the value to be compared against
	   (the string argument to "file_contents_eq()" and the regular expression argument to "file_contents_like()", for example, must be
	   decoded to Perl's internal form. The simplest way to do so use to put

	     use utf8;

	   In your test file and write it all in "UTF-8". For example:

	     use utf8;
	     use Test::More tests => 1;
	     use Test::File::Contents;

	     file_contents_eq('utf8.txt',   'aaaaaa', { encoding => 'UTF-8' });
	     file_contents_eq('latin1.txt', 'aaaaaa', { encoding => 'UTF-8' });

       "style"
	   The style of diff to output in the diagnostics in the case of a failure in "file_contents_eq_or_diff". The possible values are:

	   Unified
	   Context
	   OldStyle
	   Table
       "context"
	   Determines the amount of context displayed in diagnostic diff output. If you need to seem more of the area surrounding different lines,
	   pass this option to determine how many more links you'd like to see.

   Test Functions
       file_contents_eq

	 file_contents_eq $file, $string, $description;
	 file_contents_eq $file, $string, { encoding => 'UTF-8' };
	 file_contents_eq $file, $string, { encoding => ':bytes' }, $description;

       Checks that the file's contents are equal to a string. Pass in a Unix-style file name and it will be converted for the local file system.
       Supported options:

       "encoding"

       The old name for this function, "file_contents_is", remains as an alias.

       file_contents_eq_or_diff

	 file_contents_eq_or_diff $file, $string, $description;
	 file_contents_eq_or_diff $file, $string, { encoding => 'UTF-8' };
	 file_contents_eq_or_diff $file, $string, { style    => 'context' }, $description;

       Like "file_contents_eq()", only in the event of failure, the diagnostics will contain a diff instead of the full contents of the file. This
       can make it easier to test the contents of very large text files, and where only a subset of the lines are different. Supported options:

       "encoding"
       "style"
       "context"

       file_contents_ne

	 file_contents_ne $file, $string, $description;
	 file_contents_ne $file, $string, { encoding => 'UTF-8' };
	 file_contents_ne $file, $string, { encoding => ':bytes' }, $description;

       Checks that the file's contents do not equal a string. Pass in a Unix-style file name and it will be converted for the local file system.
       Supported options:

       "encoding"

       The old name for this function, "file_contents_isnt", remains as an alias.

       file_contents_like

	 file_contents_like $file, qr/foo/, $description;
	 file_contents_like $file, qr/foo/, { encoding => 'UTF-8' };
	 file_contents_like $file, qr/foo/, { encoding => ':bytes' }, $description;

       Checks that the contents of a file match a regular expression. The regular expression must be passed as a regular expression object created
       by "qr//".  Supported options:

       "encoding"

       file_contents_unlike

	 file_contents_unlike $file, qr/foo/, $description;
	 file_contents_unlike $file, qr/foo/, { encoding => 'UTF-8' };
	 file_contents_unlike $file, qr/foo/, { encoding => ':bytes' }, $description;

       Checks that the contents of a file do not match a regular expression. The regular expression must be passed as a regular expression object
       created by "qr//". Supported options:

       "encoding"

       file_md5sum_is

	 file_md5sum_is $file, $md5sum, $description;
	 file_md5sum_is $file, $md5sum, { encoding => 'UTF-8' };
	 file_md5sum_is $file, $md5sum, { encoding => ':bytes' }, $description;

       Checks whether a file matches a given MD5 checksum. The checksum should be provided as a hex string, for example,
       "6df23dc03f9b54cc38a0fc1483df6e21".  Pass in a Unix-style file name and it will be converted for the local file system. Supported options:

       "encoding"
	   Probably not useful unless left unset or set to ":raw".

       The old name for this function, "file_md5sum", remains as an alias.

       files_eq

	 files_eq $file1, $file2, $description;
	 files_eq $file1, $file2, { encoding => 'UTF-8' };
	 files_eq $file1, $file2, { encoding => ':bytes' }, $description;

       Tests that the contents of two files are the same. Pass in a Unix-style file name and it will be converted for the local file system.
       Supported options:

       "encoding"

       The old name for this function, "file_contents_identical", remains as an alias.

       files_eq_or_diff

	 files_eq_or_diff $file1, $file2, $description;
	 files_eq_or_diff $file1, $file2, { encoding => 'UTF-8' };
	 files_eq_or_diff $file1, $file2, { style    => 'context' }, $description;

       Like "files_eq()", this function tests that the contents of two files are the same. Unlike "files_eq()", on failure this function outputs a
       diff of the two files in the diagnostics. Supported options:

       "encoding"
       "style"
       "context"
