# NAME

Test::Some - test a subset of tests

# VERSION

version 0.0.1

# SYNOPSIS

    use Test::More;

    use Test::Some 'foo';

    plant tests => 3;

    subtest foo => sub { pass };

    # will be skipped
    subtest bar => sub { fail };

# DESCRIPTION

This module allows to run a subset of the 'subtest' tests given in a test file.

The module declaration takes a whitelist of the subtests we want to run. 
Any subtest that doesn't match any of the whitelist
items will be skipped (or potentially bypassed).

The test files don't even need to be modified, as t
he module can also be invoked from the command-line. E.g.,

    perl -MTest::Some=foo t/tests.t

## Whitelist items

### '~'

Tells Test::Some to bypass the non-whitelisted tests instead of skipping them. That makes for a smaller output, but
the test file would now fail if it has a `plan tests =` $n> line (as we'll only report on `$n - bypassed` tests). 

### Subtest name

At its most simple, the names of the subtests we want to run can be passed.

    # run subtests 'foo' and 'bar'
    use Test::Some 'foo', 'bar';

### Negation

An item prefixed with a bang (!) is negated.

    use Test::Some '!foo';  # run all tests but 'foo'

Note that a subtest is run if it matches any item in the whitelist, so

    use Test::Some '!foo', '!bar';

will run all tests as \`foo\` is not \`bar\` and vice versa.

### Regular expression

A string beginning with a slash (/), or a regular expression object 
will be considered to be a regular expression to be compared against the
subtest name

    use Test::Some '/foo';  # only tests with 'foo' in their name

    # equivalent to 
    use Test::Some qr/foo/;

### Tags

Strings prefixed with a colon (:) are considered to be tags. 

    # run all tests with the 'basic' tag
    use Test::Some ':basic';

Tags can be assigned to a subtest by putting them
after the coderef. E.g.,

    subtest foo, sub { 
        ...     
    }, 'tag1', 'tag2';

Test::More's subtest ignore those trailing arguments, so they be put there without
breaking backward compatibility.

### Code

A coderef can be passed. It'll have the subtest name and its tags passed in as 
\`$\_\` and \`%\_\`, respectively.

    # run tests with tags 'important' *and* 'auth'
    use Test::Some sub { 
        $_{important} and $_{auth} 
    };
