ClickHouse Tests in TestFlows

This directory contains integration tests written using TestFlows that involves several ClickHouse instances, custom configs, ZooKeeper, etc.

Supported environment

• Ubuntu 18.04
• Python 3 >= 3.6

Prerequisites

• Docker install
• Docker Compose install
• TestFlows install

Running tests locally

You can run tests locally by passing --local and --clickhouse-binary-path to the regression.py.

• --local specifies that regression will be run locally
• --clickhouse-binary-path specifies the path to the ClickHouse binary that will be used during the regression run

Note: you can pass -h or --help argument to the regression.py to see a help message.

python3 regression.py -h

Note: make sure that the ClickHouse binary has correct permissions. If you are using /usr/bin/clickhouse its owner and group is set to root:root by default and it needs to be changed to clickhouse:clickhouse. You can change the owner and the group using the following command.

sudo chown clickhouse:clickhouse /usr/bin/clickhouse

Using the default ClickHouse installation and its server binary at /usr/bin/clickhouse, you can run regressions locally using the following command.

python3 regression.py --local --clickhouse-binary-path "/usr/bin/clickhouse"

Output Verbosity

You can control verbosity of the output by specifying the output format with -o or --output option. See --help for more details.
