From 6994da5173a60e770163cd5fc65f73b24066c0a5 Mon Sep 17 00:00:00 2001 From: Davide Brunato Date: Thu, 20 Jun 2019 07:31:00 +0200 Subject: [PATCH 01/91] Code refactoring for tests - Rename XMLSchemaTestCase to XsdValidatorTestCase - Add casepath() helper - Modify TestResources: derive from TestCase and use casepath() - Split test_package.py into 3 modules (added test_etree.py and test_memory.py) - Update .tox with new environments 'package' and 'memory' - Replace test_package with test_etree into test_all.py script - Modify XsdValidatorTestCase.check_schema() to use xs prefix for XSD namespace and no namespace as targetNamespace for a fast reuse of common and user sample cases --- .gitignore | 3 +- doc/conf.py | 2 +- setup.py | 4 +- tox.ini | 19 +- xmlschema/__init__.py | 2 +- xmlschema/tests/__init__.py | 93 +++-- xmlschema/tests/test_all.py | 4 +- xmlschema/tests/test_etree.py | 97 +++++ xmlschema/tests/test_helpers.py | 3 +- xmlschema/tests/test_memory.py | 107 +++++ xmlschema/tests/test_models.py | 6 +- xmlschema/tests/test_package.py | 169 -------- xmlschema/tests/test_resources.py | 46 +-- xmlschema/tests/test_schemas.py | 632 ++++++++++++++++------------- xmlschema/tests/test_validators.py | 196 ++++----- xmlschema/tests/test_xpath.py | 8 +- 16 files changed, 730 insertions(+), 661 deletions(-) create mode 100644 xmlschema/tests/test_etree.py create mode 100644 xmlschema/tests/test_memory.py diff --git a/.gitignore b/.gitignore index 3c1ce44..710bdda 100644 --- a/.gitignore +++ b/.gitignore @@ -6,7 +6,8 @@ *.json .idea/ .tox/ -.coverage +.coverage* +!.coveragerc .ipynb_checkpoints/ doc/_*/ dist/ diff --git a/doc/conf.py b/doc/conf.py index cd13579..19559b7 100644 --- a/doc/conf.py +++ b/doc/conf.py @@ -62,7 +62,7 @@ author = 'Davide Brunato' # The short X.Y version. version = '1.0' # The full version, including alpha/beta/rc tags. -release = '1.0.13' +release = '1.0.14' # The language for content autogenerated by Sphinx.
