ClickHouse integration tests

This directory contains tests that involve several ClickHouse instances, custom configs, ZooKeeper, etc.

Running natively

Prerequisites:

  • Ubuntu 14.04 (Trusty) or higher.
  • docker. Minimum required API version: 1.25, check with docker version.

You must install latest Docker from https://docs.docker.com/engine/installation/linux/docker-ce/ubuntu/#set-up-the-repository Don't use Docker from your system repository.

  • pip and libpq-dev. To install: sudo apt-get install python-pip libpq-dev
  • py.test testing framework. To install: sudo -H pip install pytest
  • docker-compose and additional python libraries. To install: sudo -H pip install docker-compose docker dicttoxml kazoo PyMySQL psycopg2 pymongo tzlocal kafka-python protobuf pytest-timeout

(highly not recommended) If you really want to use OS packages on modern debian/ubuntu instead of "pip": sudo apt install -y docker docker-compose python-pytest python-dicttoxml python-docker python-pymysql python-pymongo python-tzlocal python-kazoo python-psycopg2 python-kafka python-pytest-timeout

If you want to run the tests under a non-privileged user, you must add this user to docker group: sudo usermod -aG docker $USER and re-login. (You must close all your sessions (for example, restart your computer)) To check, that you have access to Docker, run docker ps.

Run the tests with the pytest command. To select which tests to run, use: pytest -k <test_name_pattern>

By default tests are run with system-wide client binary, server binary and base configs. To change that, set the following environment variables:

  • CLICKHOUSE_TESTS_SERVER_BIN_PATH to choose the server binary.
  • CLICKHOUSE_TESTS_CLIENT_BIN_PATH to choose the client binary.
  • CLICKHOUSE_TESTS_BASE_CONFIG_DIR to choose the directory from which base configs (config.xml and users.xml) are taken.

Running with runner script

The only requirement is fresh docker configured docker.

Notes:

  • If you want to run integration tests without sudo you have to add your user to docker group sudo usermod -aG docker $USER. More information about docker configuration.
  • If you already had run these tests without ./runner script you may have problems with pytest cache. It can be removed with rm -r __pycache__ .pytest_cache/.
  • Some tests maybe require a lot of resources (CPU, RAM, etc.). Better not try large tests like test_cluster_copier or test_distributed_ddl* on your notebook.

You can run tests via ./runner script and pass pytest arguments as last arg:

$ ./runner --binary $HOME/ClickHouse/dbms/programs/clickhouse  --bridge-binary $HOME/ClickHouse/dbms/programs/clickhouse-odbc-bridge --configs-dir $HOME/ClickHouse/dbms/programs/server/ 'test_odbc_interaction -ss'

$ export CLICKHOUSE_TESTS_ODBC_BRIDGE_BIN_PATH=$HOME/ClickHouse/dbms/programs/clickhouse-odbc-bridge

You can just open shell inside a container by overwritting the command: ./runner --command=bash

Adding new tests

To add new test named foo, create a directory test_foo with an empty __init__.py and a file named test.py containing tests in it. All functions with names starting with test will become test cases.

helpers directory contains utilities for:

  • Launching a ClickHouse cluster with or without ZooKeeper indocker containers.
  • Sending queries to launched instances.
  • Introducing network failures such as severing network link between two instances.

To assert that two TSV files must be equal, wrap them in the TSV class and use the regular assert statement. Example: assert TSV(result) == TSV(reference). In case the assertion fails, pytest will automagically detect the types of variables and only the small diff of two files is printed.
