This adds snakeviz to dev tools and also updates the message displayed
upon running `test-backend` with `--profile` option to say how to run
snakeviz correctly when using vagrant development environment.
This causes `upgrade-zulip-from-git`, as well as a no-option run of
`tools/build-release-tarball`, to produce a Zulip install running
Python 3, rather than Python 2. In particular this means that the
virtualenv we create, in which all application code runs, is Python 3.
One shebang line, on `zulip-ec2-configure-interfaces`, explicitly
keeps Python 2, and at least one external ops script, `wal-e`, also
still runs on Python 2. See discussion on the respective previous
commits that made those explicit. There may also be some other
third-party scripts we use, outside of this source tree and running
outside our virtualenv, that still run on Python 2.
In this commit we basically start to override the request method of
httplib2.Http() to raise an exception whenever it is called i.e.
a trial is made to access the network from test suits.
Fixes: #1472.
The problem this commit solves is related to how we search for
testcases in the test files. We use a simple 'search_key' in file_data.
This will return a false positive if there is a 'longer_search_key' in
file_data.
While searching for TestCases we should use a longer key to remove the
possibility of collision. Using 'class TestCase(' should be precise
enough.
Fixes#4983
We enable data_suffix option when creating Coverage instances which
causes the output files to include the hostname, pid, and random id.
Before each run erase is called which clears all existing coverage data
files. And then at the end of the test run use the combine method which
merges the reports.
We collect coverage in the main process which collects data from
imports and also when running in single process mode. In the workers we
collect coverage in run_subsuite. This creates more stats files than
strictly required but I don't see a better place to save the stats when
stopping workers.
Note that this has the side effect of enabling parallel testing in
Travis CI.
This commit changes the backend testing framework to run
in parallel mode which is same as --processes=4. If --coverage
is supplied, we enforce serial mode, --processes=1, because
coverage is not compatible with parallel mode at the moment.
This fixes the fact that our test suites would have trouble connecting
to the other parts of the Zulip service when run with a proxy
configuration (e.g. trying to send requests to localhost through the
proxy!).
Thanks for Vishnu Ks for his work on this.
Fixes#971.
In backend tests, only call generate-fixtures when --generate-fixtures
is explicitly passed or is_template_database_current() returns False.
We don't need to flush cache for backend tests because we bounce the key
prefix used to create cache keys before running every test
This adds the option '--rerun' to the `test-backend` infrastructure.
It runs the tests that failed during the last 'test-backend' run. It
works by stailing failed test info at var/last_test_failure.json
Cleaned up by Umair Khan and Tim Abbott.
This code was added as part of the Django 1.10 migration to make our
tests work with both Django 1.8 and 1.10. Now that we're on 1.10,
it's no longer required.
Like many rare-case code with new tests, it turns out that the logic
for handling null characters in our Zephyr postgres query escaping
never worked, in multiple ways. First, it always changed the second
character in s, not the current one being inspected, and second, the
value it replaced it with was no the correct postgres escape of the
null byte. We fix this and add tests.
This completes the effort to get zerver/views/messages.py to 100%
test coverage.
Fixes#1006.
This adds an assertion, when `test-backend` is run with `--coverage`,
that we have 100% test coverage on a list of files that we expect to.
There's a whitelist/blacklist, managed in tools/test-backend.
Fixes#3363.
This helps make the Zulip development environment somewhat more robust
to new contributors, since it will give them a nice warning if they
try running any of our development tools outside the Zulip virtualenv.
Fixes#3468.
We now instrument URL coverage whenever you run the back end tests,
and if you run the full suite and fail to test all endpoints, we
exit with a non-zero exit code and report failures to you.
If you are running just a subset of the test suite, you'll still
be able to see var/url_coverage.txt, which has some useful info.
With some tweaks to the output from tabbott.
Fixes#1441.
These are not particularly interesting to measure test coverage for,
since migrations are not run as the part of the test suite by
construction, and management commands aren't being tested by this test
suite.
Previously, running `tools/test-backend analytics/` (or any other test suite
name ending with a '/') would give a cryptic error about modules not
importing properly. This commit rstrip's the trailing slash from test suite
names given on the command line.
Previously, the generate-fixtures shell script by called into Django
multiple times in order to check whether the database was in a
reasonable state. Since there's a lot of overhead to starting up
Django, this resulted in `test-backend` and `test-js-with-casper`
being quite slow to run a single small test (2.8s or so) even on my
very fast laptop.
We fix this is by moving the checks into a new Python library, so that
we can avoid paying the Django startup overhead 3 times unnecessarily.
The result saves about 1.2s (~40%) from the time required to run a
single backend test.
Fixes#1221.
This is a first pass at building a framework for collecting various
stats about realms, users, streams, etc. Includes:
* New analytics tables for storing counts data
* Raw SQL queries for pulling data from zerver/models.py tables
* Aggregation functions for aggregating hourly stats into daily stats, and
aggregating user/stream level stats into realm level stats
* A management command for pulling the data
Note that counts.py was added to the linter exclude list due to errors
around %%s.
This optimizes the process of running individual or small groups of
backend tests (./tools/test-backend
zerver.tests.test_bugdown.FencedBlockPreprocessorTest.test_simple_quoting)
to allow the following syntaxes:
./tools/test-backend zerver/tests/test_bugdown.py
./tools/test-backend zerver.tests.test_bugdown.py
./tools/test-backend zerver/tests/test_bugdown
./tools/test-backend zerver.tests.test_bugdown
./tools/test-backend test_bugdown.py
./tools/test-backend test_bugdown
./tools/test-backend FencedBlockPreprocessorTest
./tools/test-backend FencedBlockPreprocessorTest.test_simple_quoting
Fixes#1670.
