l.r.t.t.TestProberFactoryRequestTimeoutRatioWithoutTwisted(TestCase) : class documentation

Part of lp.registry.tests.test_distributionmirror_prober View In Hierarchy

Tests to ensure we stop issuing requests on a given host if the requests/timeouts ratio on that host is too low.

The tests here will stub the prober's connect() method, so that we can easily check whether it was called or not without actually issuing any connections.

Inherited from TestCase:

Method becomeDbUser Commit, then log into the database as dbuser.
Method __str__ The string representation of a test is its id.
Method useContext Use the supplied context in this test.
Method makeTemporaryDirectory Create a temporary directory, and return its path.
Method installKarmaRecorder Set up and return a KarmaRecorder.
Method assertProvides Assert 'obj' correctly provides 'interface'.
Method assertNotifies Assert that a callable performs a given notification.
Method assertNoNotification Assert that no notifications are generated by the callable.
Method assertSqlAttributeEqualsDate Fail unless the value of the attribute is equal to the date.
Method assertTextMatchesExpressionIgnoreWhitespace Undocumented
Method assertIsInstance Assert that an instance is an instance of assert_class.
Method assertIsNot Assert that expected is not the same object as observed.
Method assertContentEqual Assert that 'iter1' has the same content as 'iter2'.
Method assertRaisesWithContent Check if the given exception is raised with given content.
Method assertBetween Assert that 'variable' is strictly between two boundaries.
Method assertVectorEqual Apply assertEqual to all given pairs in one go.
Method expectedLog Expect a log to be written that matches the regex.
Method pushConfig Push some key-value pairs into a section of the config.
Method attachOopses Undocumented
Method attachLibrarianLog Include the logChunks from fixture in the test details.
Method assertStatementCount Assert that the expected number of SQL statements occurred.
Method useTempDir Use a temporary directory for this test.
Method assertEmailHeadersEqual Assert that two email headers are equal.
Method assertStartsWith Undocumented
Method assertEndsWith Asserts that s ends with suffix.
Method checkPermissions Check if the used_permissions match expected_permissions.
Method assertEmailQueueLength Pop the email queue, assert its length, and return it.
Method _unfoldEmailHeader Unfold a multiline email header.

def _createProberStubConnectAndProbe(self, requests, timeouts):
Create a ProberFactory object with a URL inside self.host and call its probe() method.

Before the prober.probe() method is called, we stub the connect method, because all we want is to check whether that method was called or not --we don't want to actually connect.

def test_connect_is_called_if_not_enough_requests(self):
Test that only a small ratio is not enough to cause a host to be skipped; we also need to have a considerable number of requests.
def test_connect_is_not_called_after_too_many_timeouts(self):
If we get a small requests/timeouts ratio on a given host, we'll stop issuing requests on that host.
def test_connect_is_called_if_not_many_timeouts(self):
Undocumented
