=item True()

test for a scalar value that evaluates to true.

Send a scalar value to this function along with the test's name:

    $UnitTestObject->True(1, 'Test Name');

    $UnitTestObject->True($ParamA, 'Test Name');

Internally, the function receives this value and evaluates it to see
if it's true, returning 1 in this case or undef, otherwise.

    my $TrueResult = $UnitTestObject->True(
        $TestValue,
        'Test Name',
    );

    }
    else {
        $Self->_Print( 0, $Name );
        return;
    }
}

=item False()

test for a scalar value that evaluates to false.

It has the same interface as L</True()>, but tests
for a false value instead.

=cut

sub False {
    my ( $Self, $False, $Name ) = @_;

    if ( !$Name ) {

=item Is()

compares two scalar values for equality.

To this function you must send a pair of scalar values to compare them,
and the name that the test will take, this is done as shown in the examples
below.

    $UnitTestObject->Is($A, $B, 'Test Name');

Returns 1 if the values were equal, or undef otherwise.

    my $IsResult = $UnitTestObject->Is(
        $ValueFromFunction,      # test data
        1,                       # expected value

        $Self->_Print( 0, "$Name (is '$Test' should be '$ShouldBe')" );
        return;

compares two scalar values for inequality.

It has the same interface as L</Is()>, but tests
for inequality instead.

        return;

}

=item IsDeeply()

compares complex data structures for equality.

To this function you must send the references to two data structures to be compared,
and the name that the test will take, this is done as shown in the examples
below.

    $UnitTestObject-> IsDeeply($ParamA, $ParamB, 'Test Name');

Where $ParamA and $ParamB must be references to a structure (scalar, list or hash).

Returns 1 if the data structures are the same, or undef otherwise.

    my $IsDeeplyResult = $UnitTestObject->IsDeeply(
        \%ResultHash,           # test data
        \%ExpectedHash,         # expected value
