How to run tests

The clickhouse-test utility that is used for functional testing is written using Python 2.x.
It also requires you to have some third-party packages:

$ pip install lxml termcolor

In a nutshell:

• Put the clickhouse program to /usr/bin (or PATH)
• Create a clickhouse-client symlink in /usr/bin pointing to clickhouse
• Start the clickhouse server
• cd dbms/tests/
• Run ./clickhouse-test

Example usage

Run ./clickhouse-test --help to see available options.

To run tests without having to create a symlink or mess with PATH:

./clickhouse-test -c "../../build/dbms/src/Server/clickhouse --client"

To run a single test, i.e. 00395_nullable:

./clickhouse-test 00395
