Terragraph CTF

Terragraph is a gigabit wireless technology designed to meet the growing demand for reliable high-speed internet access. Documentation for the project can be found at terragraph.com.

This repository contains a comprehensive automated test suite for Terragraph, consisting of test implementations and a test runner application for the Connectivity Testing Framework (CTF) developed by Meta. Test plan documentation can be found here.

Building

Dependencies

• Python 3.8
• requests - Used in test implementations
• later - Used for unit tests
• pandas - Used in SIT routing tests to analyze data by columns

Installation

# Init venv
$ python3 -m venv venv
$ source ./venv/bin/activate

# Install dependencies
$ pip install --upgrade pip
$ cd ./ctf/ctf_client/ ; pip install -r requirements.txt ; cd -
$ cd ./ctf/common/     ; pip install -r requirements.txt ; cd -
$ pip install requests later pandas

# Run CTF
$ export EXTERNAL_DEPLOYMENT=True
$ python3 tg_ctf_runner.py --help

# Run unit tests
$ python3 -m unittest terragraph/ctf/unittests_lib.py

Usage

Commands

• run <TestName> - Run a CTF test (or test suite)
• describe <TestName> - Show test description and parameters
• list-tests - List all tests (and test suites)
• list-setups - List all setups registered in CTF
• force-free <id> - Forcefully free a test setup

Credentials

CTF credentials must be provided in any of the following ways:

1. ~/.ctf_config file:

{
  "user": "user@fb.com",
  "pwd": "<your CTF password>",
  "api_server_url": "https://openctf.io/",
  "file_server_url": "https://openctf.io/"
}

2. Environment variables:

CTF_USER
CTF_PASSWORD
CTF_API_SERVER_URL
CTF_FILE_SERVER_URL

Serverless Mode

The CTF client includes a "serverless" feature which allows running tests locally without a CTF server instance. The test results are stored on the local machine. To enable this mode, pass --serverless=true to the "run" command, for example:

python3 tg_ctf_runner.py run TestTgCtfTest --test-setup-id 1 --serverless=true

This requires additional configuration files as listed below:

1. Create ~/.ctf_serverless_config with the following contents:

{
  "test_setups_dir": "/path/to/test_setups_dir",
  "test_results_dir": "/path/to/test_results_dir",
  "ctf_client_app_data": "/path/to/ctf_client_app_data"
}

2. Create the test setup files, which will hold all the devices and their connection details. The files must be named <setup_id>.json within the "test_results_dir" directory, for example 1.json with the contents below:
