mindsdb--minds

api: Contains tests related to the MindsDB's API endpoints.
integration: Contains the integration tests
load: Contains the load tests
scripts: Scripts and utilitis used for tests
unit: This directory contains the unit tests: * handlers: A subset of unit tests specifically targeting data handlers. * ml_handlers: A subset of unit tests specifically targeting ML handlers.

Installation

To run the tests, you need to install the necessary dependencies. You can do this by running the following command:

pip install -r requirements/requirements.txt -r requirements/requirements-test.txt

This command will install all the required packages as listed in requirements-test.txt and the requirements.txt files.

Note: You will also need to install the dependencies required by any of the integrations that the tests you are running use. This can be done by running pip install .[<integration_name>] in the root directory of the repository.

Runing tests

Unit and Integration Tests

To execute unit or integration tests, use the following pytest command:

pytest -vx <test_dir>

For example, to run the unit tests for the handlers, use the following command:

pytest -vx tests/unit/handlers

Load Tests

For load testing, we use locust:

locust -f test_start.py --headless -u <number_of_users> -r <spawn_rate>

Options:

--headless: Runs Locust in headless mode without the web UI.
-u: Specifies the total number of users to simulate.
-r: Defines the spawn rate of users, i.e the number of users to spawn per second.

Note: The load tests require an environment variable called INTEGRATIONS_CONFIG to be set containing information related to the testing environments used. These environments will also need be pre-loaded with the necessary data for the tests to run successfully.

Generating Test Reports

We use pytest for running tests and coveralls for generating test coverage reports. To run the tests and generate a coverage report, use the following command:

pytest --cov=<code_dir> <test_dir> && coveralls

For example, to run tests for the HTTP API, use the following command:

pytest --cov=mindsdb/api/http tests/unit/api/http && coveralls

For the above command to be successful, you need to either have the COVERALLS_REPO_TOKEN environment variable set to your Coveralls token or have a .coveralls.yml file in the root directory of the repository with the token.

Otherwise, you simply run the following command:

pytest --cov=<code_dir> <test_dir>
