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.
