NAME ^

XML::Compile::Tester - support XML::Compile related regression testing

INHERITANCE ^

 XML::Compile::Tester
   is a Exporter

SYNOPSIS ^

 use XML::Compile::Tester;

 # default additional compile flags, avoids repetition
 set_compile_defaults(validation => 0, @other_opts);
 set_compile_defaults();  # reset

 # set default namespace, such that $type only needs to use local
 my $ns     = 'some-schemas-targetNamespace';
 my $type   = pack_type($ns, 'localName'); # X::C::Util
 set_default_namespace($ns);
 my $type   = 'localName'; # now implicit in $ns

 my $reader = reader_create($schema, "my reader", $type, @opts);
 my $data   = $reader->($xml);  # $xml is string, filename, node

 my $writer = writer_create($schema, "my writer", $type, @opts);
 my $xml    = $writer->($doc, $data);
 my $xml    = writer_test($writer, $data);

 my $rerror = reader_error($schema, $type, $xml);
 my $werror = writer_error($schema, $type, $data);

 my $output = templ_xml($schema, $type, @options);
 my $output = templ_perl($schema, $type, @options);

DESCRIPTION ^

The XML::Compile module suite has extensive regression testing. Probably, you want to do regression testing as well. This module provide functions which simplify writing tests for XML::Compile related distributions.

FUNCTIONS ^

Reader checks

reader_create(SCHEMA, COMMENT, TYPE, OPTIONS)

Create a reader for TYPE. One test is created, reporting success or failure of the creation.

Of course, XML::Compile::Schema subroutine compile is being called, with some options. By default, check_values is true, and include_namespaces is false. These values can be overruled using set_compile_defaults(), and with the OPTIONS parameter list.

example: reader_create

 my $type   = pack_type('namespace', 'localName');
 my $reader = reader_create($schema, 'my test', $type
   , check_occurs => 0, @other_options);

 my $data   = $reader->($xml);
 is_deeply($data, $expected, 'my test');  # Test::More
 cmp_deeply($data, $expected, 'my test'); # Test::Deep

 # alternative for $type:
 set_default_namespace('namespace');
 my $reader = reader_create($schema, 'my test', 'localName'
   , check_occurs => 0, @other_options);
reader_error(SCHEMA, TYPE, XML)

Parsing the XML to interpret the TYPE should return an error. The error text is returned.

example: reader_error

 my $error = reader_error($schema, $type, <<_XML);
 <test1>...</test1>
 _XML

 is($error, 'error text', 'my test');
 like($error, qr/error pattern/, 'my test');

Writer checks

writer_create(SCHEMA, COMMENT, TYPE, OPTIONS)

Create a writer for TYPE. One test (in the Test::More sense) is created, reporting success or failure of the creation.

Of course, XML::Compile::Schema subroutine compile is being called, with some options. By default, check_values and use_default_namespace are true, and include_namespaces is false. These values can be overruled using set_compile_defaults(), and with the OPTIONS parameter list.

example: writer_create

 set_default_namespace('namespace');
 my $writer = writer_create($schema, 'my test', 'test1');

 my $doc    = XML::LibXML::Document->new('1.0', 'UTF-8');
 my $xml    = $writer->($doc, $data);
 compare_xml($xml, <<_EXPECTED, 'my test');
   <test1>...</test1>
 _EXPECTED

 # implicit creation of $doc
 my $xml    = writer_test($writer, $data);
writer_error(SCHEMA, TYPE, DATA)

Translating the Perl DATA into the XML type should return a validation error, which is returned.

example: writer_error

 my $error = writer_error($schema, $type, $data);

 is($error, 'error text', 'my test');
 like($error, qr/error pattern/, 'my test');
writer_test(WRITER, DATA, [DOC])

Run the test with a compiled WRITER, which was created with writer_create(). When no DOC (XML::LibXML::Document object) was specified, then one will be created for you.

Check templates

templ_perl(SCHEMA, TYPE, OPTIONS)
templ_xml(SCHEMA, TYPE, OPTIONS)

Create an example template for TYPE, as XML message. The OPTIONS are passed to XML::Compile::Schema subroutine template.

example: templ_xml

 my $out = templ_xml($schema, $type, show => 'ALL');
 is($out, $expected);

Helpers

compare_xml(XML, EXPECTED, [COMMENT])

Compare the XML (either a string or an XML::LibXML::Element) with the EXPECTED string. Both sources are stripped from layout before comparing.

In a future release, this algorithm will get improved to compare the parsed XML node trees, not the strings.

example: compare_xml

 compare_xml($xml, <<_XML, 'my test');
   <test1>...</test1>
 _XML
set_compile_defaults(OPTIONS)

Each call to create a reader or writer (also indirectly) with XML::Compile::Schema subroutine compile will get these OPTIONS passed, on top (and overruling) the usual settings.

example:

 # defaults for XML::Compile::Schema::compile()
 set_compile_defaults(include_namespaces => 1, validate => 0
   , sloppy_intergers => 1, sloppy_floats => 1);

 set_compile_defaults();   # reset
set_default_namespace(TESTNS)

Defined which namespace to use when a relative (only localName) type is provided. By default, this is undef (an error when used)
