The reason why we need to refactor constant runner are as follows: 1) using processes to genereate load is to expensive The optimal way to do thing is to create N processes (where N is amount of cpu) and use threads. 2) using multiprocessing.Pool() doesn't allow us to make proper timeouts 3) using multprocessing.Pool() doesn't allow us to stop imidiatelly load (when we run runner.abort()) What has also been done in this patch: 1) Unification of common part between rps and new constant runner 2) Using RAMInt for iterations counting in the RPS runner as well 3) Added a "sleep" parameter in Dummy.dummy_exception. This will allow us a better functional testing for the "--abort-on-sla-failure" feature. 4) Minor fix in SLA ToDo in next patches: * Implement timeouts * Work on the constant for duration runner Co-Authored-By: Boris Pavlovic <boris@pavlovic.me> Co-Authored-By: Mikhail Dubov <mdubov@mirantis.com> Change-Id: I49bcc8694e10b3bbb8dcf5c9fe52e29e48a985f3
Testing
Please, don't hesitate to write tests ;)
Unit tests
Files: /tests/unit/*
The goal of unit tests is to ensure that internal parts of the code work properly. All internal methods should be fully covered by unit tests with a reasonable mocks usage.
About Rally unit tests:
- All unit tests are located inside /tests/unit/*
- Tests are written on top of: testtools, fixtures and mock libs
- Tox is used to run unit tests
To run unit tests locally:
$ pip install tox
$ tox
To run py26, py27 or pep8 only:
$ tox -e <name>
#NOTE: <name> is one of py26, py27 or pep8
To run py26, py27 against mysql or psql
$ export RALLY_UNITTEST_DB_URL="mysql://user:secret@localhost/rally" $ tox -epy27
To get test coverage:
$ tox -e cover
#NOTE: Results will be in /cover/index.html
To generate docs:
$ tox -e docs
#NOTE: Documentation will be in doc/source/_build/html/index.html
Functional tests
Files: /tests/functional/*
The goal of functional tests is to check that everything works well together. Fuctional tests use Rally API only and check responses without touching internal parts.
To run functional tests locally:
$ source openrc
$ rally deployment create --fromenv --name testing
$ tox -e cli
#NOTE: openrc file with OpenStack admin credentials
Output of every Rally execution will be collected under some reports root in directiry structure like: reports_root/ClassName/MethodName_suffix.extension This functionality implemented in tests.functional.utils.Rally.__call__ method. Use 'gen_report_path' method of 'Rally' class to get automaticaly generated file path and name if you need. You can use it to publish html reports, generated during tests. Reports root can be passed throw environment variable 'REPORTS_ROOT'. Default is 'rally-cli-output-files'.
Rally CI scripts
Files: /tests/ci/*
This directory contains scripts and files related to the Rally CI system.
Rally Style Commandments
File: /tests/hacking/checks.py
This module contains Rally specific hacking rules for checking commandments.
