In the Django shell:
from django.test import SimpleTestCase
c = SimpleTestCase()
haystack = '<html><b>contribution</b></html>'
c.assertInHTML('<b>contribution</b>', haystack)
c.assertInHTML('contribution', haystack)
I do not understand why the first statement passes, but the second does not:
AssertionError Traceback (most recent call last)
<ipython-input-15-20da22474686> in <module>()

6 c.assertInHTML('<b>contribution</b>', haystack)
c:\...\lib\site-packages\django\test\testcases.py in assertInHTML(self, needle, haystack, count, msg_prefix)
680 else:
681 self.assertTrue(real_count != 0,
683
684 def assertJSONEqual(self, raw, expected_data, msg=None):
C:\...\Programs\Python\Python35-32\lib\unittest\case.py in assertTrue(self, expr, msg)
675 if not expr:
676 msg = self._formatMessage(msg, "%s is not true" % safe_repr(expr))

679 def _formatMessage(self, msg, standardMsg):
AssertionError: False is not true : Couldn't find 'contribution' in response
Django docs will simply say: "The arguments passed must be valid HTML." I do not think this is a problem because the call assert_and_parse_htmlin the first line does not rise:
def assertInHTML(self, needle, haystack, count=None, msg_prefix=''):
needle = assert_and_parse_html(self, needle, None,
'First argument is not valid HTML:')
haystack = assert_and_parse_html(self, haystack, None,
'Second argument is not valid HTML:')
real_count = haystack.count(needle)
if count is not None:
self.assertEqual(real_count, count,
msg_prefix + "Found %d instances of '%s' in response"
" (expected %d)" % (real_count, needle, count))
else:
self.assertTrue(real_count != 0,
msg_prefix + "Couldn't find '%s' in response" % needle)
I am using Python 3.5.1 and Django 1.8.8.
