# Python prerequisites for `make e2e-test`

`make e2e-test` also requires a test database and, for some service tests, `libgit2`. See
[`backend/test/Readme.md`](../test/Readme.md) for the full local E2E test flow.

For the Python plugin tests to run properly, the following steps must be taken:

1. The following packages are required for Ubuntu: `libffi-dev default-libmysqlclient-dev libpq-dev`
2. `python3.9` is required by the time of this document. 
   - Try `deadsnakes` if you are using Ubuntu 22.04 or above, the `python3.9-dev` is required.
   - Use `virtualenv` if you are having multiple python versions. `virtualenv -p python3.9 path/to/venv` and `source path/to/venv/bin/activate.sh` should do the trick
3. both `mysql-client` and `postgresql` are required. 
   - `postgresql` is required for `psycopg2` to work
4. [poetry](https://python-poetry.org/) is required. 
   - run `cd backend/python/pydevlake && poetry install`
   - run `cd backend/python/plugins/azuredevops && poetry install`
5. `sqlalchemy` won't work with `localhost` in the database connection string, use `127.0.0.1` instead
