The super calls really aren't needed for either method since the base class's
setUp and tearDown are no-ops, but I added them anyways.

+    self.server = event_server.ThreadedServer()
+    self.server.start()
+
+  def tearDown(self):
+    self.server.shutdown()

[M-A Ruel, 2016/01/15 14:07:13]

try:
  self.server.shutdown()
finally:
  super(EventServerTest, self).tearDown()

[Mike Meade, 2016/01/18 20:25:51]

Done.

+
+  def Connect(self, verb, path):
+    conn = httplib.HTTPConnection('localhost', self.server.port)
+    conn.request(verb, path)

make lines 26-28 a single line

Changed in both locations.

+    resp = conn.getresponse()
+    return resp.status
+

+    self.assertEquals(self.Connect('GET', '/events/event1'), 404)
