示例1: test_export
# 需要导入模块: from babel.messages import Catalog [as 别名]
# 或者: from babel.messages.Catalog import _num_plurals [as 别名]
def test_export(self):
"""Test that the export command maintains the proper plural form,
and actually replaces an incorrect one."""
p = self.setup_project()
p.write_xml(data="""<resources></resources>""")
p.write_xml(data="""<resources></resources>""", lang='ja')
# Generate a catalog with different plural rules than we expect
catalog = Catalog('ja')
catalog._num_plurals, catalog._plural_expr = 2, '(n < 2)'
p.write_po(catalog)
# Export should override the info
assert 'Plural-Forms header' in p.program('export')
catalog = p.get_po('ja.po')
assert catalog.num_plurals == 1
assert catalog.plural_expr == '(0)'
