From af80a9e81abd83069449ecf5986e163f3192a72a Mon Sep 17 00:00:00 2001 From: John Evans Date: Sun, 17 Aug 2014 19:03:29 -0400 Subject: [PATCH 01/27] Reworked warning tests, closes #245. Using 3.x warning infrastructure to verify warnings. Using old 2.x infrastructure to suppress warnings when the point of the test is not the warning itself but something else. All tests for warnings moved into glymur.test.test_glymur_warnings. --- glymur/codestream.py | 2 +- glymur/test/test_codestream_warnings.py | 100 ------- glymur/test/test_glymur_warnings.py | 207 +++++++++++++ glymur/test/test_opj_suite.py | 126 ++++++++ glymur/test/test_opj_suite_dump.py | 168 ++++++++++- glymur/test/test_opj_suite_neg.py | 13 +- glymur/test/test_opj_suite_warn.py | 376 ------------------------ glymur/test/test_printing.py | 25 +- 8 files changed, 513 insertions(+), 504 deletions(-) delete mode 100644 glymur/test/test_codestream_warnings.py create mode 100644 glymur/test/test_glymur_warnings.py delete mode 100644 glymur/test/test_opj_suite_warn.py diff --git a/glymur/codestream.py b/glymur/codestream.py index acc7791..88babe5 100644 --- a/glymur/codestream.py +++ b/glymur/codestream.py @@ -202,7 +202,7 @@ class Codestream(object): msg = 'Invalid marker id encountered at byte {0:d} ' msg += 'in codestream: "0x{1:x}"' msg = msg.format(self._offset, self._marker_id) - warnings.warn(msg) + warnings.warn(msg, UserWarning) break self.segment.append(segment) diff --git a/glymur/test/test_codestream_warnings.py b/glymur/test/test_codestream_warnings.py deleted file mode 100644 index 8b50bf2..0000000 --- a/glymur/test/test_codestream_warnings.py +++ /dev/null @@ -1,100 +0,0 @@ -""" -Test suite for codestream parsing. -""" - -# unittest doesn't work well with R0904. -# pylint: disable=R0904 - -# tempfile.TemporaryDirectory, unittest.assertWarns introduced in 3.2 -# pylint: disable=E1101 - -import os -import struct -import sys -import tempfile -import unittest -import warnings - -from glymur import Jp2k -import glymur - -from .fixtures import opj_data_file, OPJ_DATA_ROOT - -@unittest.skipIf(sys.platform.startswith('linux'), 'warnings failing on linux') -@unittest.skipIf(OPJ_DATA_ROOT is None, - "OPJ_DATA_ROOT environment variable not set") -class TestCodestreamOpjDataWarnings(unittest.TestCase): - """Test suite for unusual codestream cases.
