NAME
    Test::Subs - Test your modules with a lightweight anonymous block based
    syntax

SYNOPSIS
      use SomeModule;
      use Test::Subs;
  
      test { 1 == 2 };

DESCRIPTION
    This module provide a very lightweight syntax to run "Test::Harness" or
    "Tap::Harness" compliant test on your code.

    As opposed to other similar packages, the two main functionnalities of
    "Test::Subs" are that the tests are anonymous code block (rather than
    list of values), which are (subjectively) cleaner and easier to read,
    and that you do not need to pre-declare the number of tests that are
    going to be run (so all modifications in a test file are local).

    Using this module is just a matter of "use Test::Subs" followed by the
    declaration of your tests with the functions described below. All tests
    are then run at the end of the execution of your test file.

    As a protection against some error, if the compilation phase fail, the
    output of the test file will be one failed pseudo-test.

FUNCTIONS
    This is a list of the public function of this library. Functions not
    listed here are for internal use only by this module and should not be
    used in any external code unless .

    All the functions described below are automatically exported into your
    package except if you explicitely request to opposite with "use
    Test::Subs ();".

    Finally, these function must all be called from the top-level and not
    inside of the code of another test function. That is because the library
    must know the number of test before their execution.

  test
      test { CODE };
      test { CODE } DESCR;

    This function register a code-block containing a test. During the
    execution of the test, the code will be run and the test will be deemed
    successful if the returned value is "true".

    The optionnal "DESCR" is a string (or an expression returning a string)
    which will be added as a comment to the result of this test. If this
    string contains a "printf" *conversion* (e.g. %s or %d) it will be
    replaced by the result of the code block.

  todo
      todo { CODE };
      todo { CODE } DESCR;

    This function is the same as the function "test", except that the test
    will be registered as *to-do*. So a failure of this test will be ignored
    when your test is run inside a test plan by "Test::Harness" or
    "Tap::Harness".

  match
      match { CODE } REGEXP;
      match { CODE } REGEXP, DESCR;

    This function declares a test which will succeed if the result of the
    code block match the given regular expression.

    The regexp may be given as a scalar string or as a "qr" encoded regexp.

  not_ok
      not_ok { CODE };
      not_ok { CODE } DESCR;

    This function is exactly the opposite of the "test" one. The test that
    it declares will succeed if the code block return a "false" value.

  fail
      fail { CODE };
      fail { CODE } DESCR;

    This function declares a test that will succeed if its code block "die"
    (raise any exception).

  failwith
      failwith { CODE } REGEXP;
      failwith { CODE } REGEXP, DESCR;

    As for the "fail" function, this function declares a test which expects
    that its code block "die". Except that the test will succeed only if the
    raised exception (the content of the $@ variable) match the given
    regular expression.

    The regexp may be given as a scalar string or as a "qr" encoded regexp.

  comment
      comment { CODE };

    This function evaluate its code and display the resulting value on the
    standard error handle. The buffering on "STDOUT" and "STDERR" is
    deactivated when "Test::Subs" is used and the output of this function
    should appear in between the result of the test when the test file is
    run stand-alone.

    This function must be used outside of the code the other functions
    described above. The output comment to "STDERR" inside a test, just use
    the "print" or "printf" function. The default output has been
    "select"-ed to "STDERR" so the result of the test will not be altered.

EXAMPLE
    Here is an example of a small test file using this module.

      use strict;
      use warnings;
      use Test::Subs;
  
      test { 1 == 1 } 'This is the first test';
  
      todo { 1 == 2 };
  
      not_ok { 0 };
  
      fail { die "fail" };

    Run through "Test::Harness" this file will pass, with only the second
    test failing (but marked *todo* so that's OK).

CAVEATS
    The standard set by "Test::Harness" is that all output to "STDOUT" is
    interpreted by the test parser. So a test file should write additional
    output only to "STDERR". This is what will be done by the "comment"
    fonction. To help with this, during the execution of your test file, the
    "STDERR" file-handle will be "select"-ed. So any un-qualified "print" or
    "printf" call will end in "STDERR".

    This package use source filtering (with "Filter::Simple"). The filter
    applied is very simple, but there is a slight possibility that it is
    incompatible with other source filter. If so, do not hesitate to report
    this as a bug.
