iXML Community Group Test Suite

21 Jun 2022 (28 Jun 2022)

Top-level catalog for tests in the iXML Community Group Test Suite.

Tests have been contributed from several sources, but the core of the test collection are the tests contributed by Steven Pemberton in December 2021.

Error tests

Tests intended to demonstrate errors that processors are required to raise.

non-XML-char-in-input-output-clear

Created 20 Jun 2022 by MSM

Followup to invalid-char. Tests for serialization of non-XML characters in a different way.

This test set is for sanity checking the inputs of the following test set: the grammar accepts a range of non-XML characters but hides all of them, indicating in the output where they were. When the outputs of these tests are as expected, we can have some confidence about exactly which invisible characters are where in the test-case inputs. We can then use the same test-case inputs with a grammar that does not hide all of the non-XML characters but tries instead to serialize them.

Invisible XML Grammar

{ Grammar for experiments with non-XML characters in input.

  In this grammar, non-XML characters are accepted in the
  input but are not shown in the output.  It's used for
  sanity-checking the inputs for tests of the companion
  grammar in which not all control characters are hidden.

  Since we need non-XML characters in the input, and the only 
  non-XML characters we can make are in the C0 range, the 
  input and output are likely to be challenging to check.
  
  You have been warned.
