Manually

If you want to test the bot by creating your personal instance, follow this steps:

• Install system requirements
• Clone this repository or download it as zip.
• Send a message to your bot on Telegram, even '/start' will do. If you don't, you could get an error
• Make a copy of the file data/DMI_DB.db.dist in the same directory and rename it to DMI_DB.db to enable the database sqlite
• Make a copy of the file config/settings.yaml.dist in the same directory and rename it to settings.yaml
• Set your token with python3 setup.py <token> or edit settings.yaml manually
• Launch the bot with python3 main.py

(If you don't have a token, message Telegram's @BotFather to create a bot and get a token for it)

To run the end-to-end tests read the following steps below.

Steps:

• Sign in your Telegram account with your phone number here. Then choose “API development tools”
• If it is your first time doing so, it will ask you for an app name and a short name, you can change both of them later if you need to. Submit the form when you have completed it
• You will then see the api_id and api_hash for your app. These are unique to your app, and not revocable.
• Edit the folling values in the config/settings.yaml file:

test:
  api_hash: hash of the telegram app used for testing
  api_id: id of the telegram app used for testing
  session: session of the telegram app used for testing (see steps below)
  tag: tag of the bot used for testing
  token: token for the bot used for testing
  representatives_group: representatives' group id used for testing
  dev_group_chatid: dev's group id used for testing

• Copy the file "tests/conftest.py" in the root folder and Run

python3 conftest.py .

• Follow the procedure and copy the session value it provides in the settings file in "test:session". You can then delete the conftest.py you just used, you won't need it again
• Edit tag value with the username of the test bot you will use.
• Edit representatives_group value with the user_id or group_id where you want receive reports from /report command.
• Edit dev_group_chatid value with the user_id or group_id where you want receive tracebacks.
