NAME

Test::Lazy::Tester

SYNOPSIS

        use Test::Lazy::Tester;

    $tester = Test::Lazy::Tester->new;

    # Will evaluate the code and check it:
        $tester->try('qw/a/' => eq => 'a');
        $tester->try('qw/a/' => ne => 'b');
        $tester->try('qw/a/' => is => ['a']);

    # Don't evaluate, but still compare:
        $tester->check(1 => is => 1);
        $tester->check(0 => isnt => 1);
        $tester->check(a => like => qr/[a-zA-Z]/);
        $tester->check(0 => unlike => qr/a-zA-Z]/);
        $tester->check(1 => '>' => 0);
        $tester->check(0 => '<' => 1);

    # A failure example:

        $tester->check([qw/a b/] => is => [qw/a b c/]);

    # Failed test '['a','b'] is ['a','b','c']'
    # Compared array length of $data
    #    got : array with 2 element(s)
    # expect : array with 3 element(s)


    # Custom test explanation:

        $tester->try('2 + 2' => '==' => 5, "Math is hard: %?");

    # Failed test 'Math is hard: 2 + 2 == 5'
    #      got: 4
    # expected: 5

DESCRIPTION

See Test::Lazy for more information.

METHODS

Test::Lazy::Tester->new( cmp_scalar => ?, cmp_structure => ?, render => ? )

Create a new Test::Lazy::Tester object, optionally amending the scalar comparison, structure comparison, and render subroutines using the supplied hashes.

For now, more information on customization can be gotten by:

    perldoc -m Test::Lazy::Tester

$tester->check( <got>, <compare>, <expect>, [ <notice> ] )

See Test::Lazy::check for details.

$tester->try( <got>, <compare>, <expect>, [ <notice> ] )

See Test::Lazy::try for details.

$tester->template()

Creates a Test::Lazy::Template using $tester as the basis.

See Test::Lazy::Template for more details.

Returns a new Test::Lazy::Template object.

$tester->render_value( <value> )

Render a gotten or expected value to a form suitable for the test notice/explanation.

This method will consult the $tester->render hash to see what if should do based on 'ref <value>'. By default, ARRAY and HASH are handled by Data::Dumper using the following:

        local $Data::Dumper::Indent = 0;
        local $Data::Dumper::Varname = 0;
        local $Data::Dumper::Terse = 1;

An undef value is a special case, handled by the $tester->render->{undef} subroutine. By default, the subroutine returns the string "undef"

$tester->render_notice( <left>, <compare>, <right>, <notice> )

Render the text explantaion message. You don't need to mess with this.
