2. Case Background

2.1. System Context, Mission and Scope

ATF is a C++/Lua framework for SDL automated black-box testing.
It provides high- and low-level API for mobile applications and/or HMIs emulation.

ATF core lua-scripts provides API for SDL easy manipulation:
- Start and stop SDL
- Emulation websocket HMI, HMI interfaces registration and subscription
- Emulation TCP mobile connection and FORD protocol session establishing
- Expectation HMI and mobile RPC from SDL
- Expectation extensions with setting up timeouts, call-chains and fields validation
- SDL messages auto-validation

2.2. Product Stakeholders

Actors are stakeholders that interact with product directly.

Stakeholder Name Actor (Yes/No) Concern
Ford Company No Get the ATF system with enough quality and functionality that fulfill their goals
SDL Automation Test teams Yes Get the ATF system with enough functionality for SDL testing coverage
PM / Architect / Analyst No Use Customer Requirements Specification
Developers No Construct and deploy the system from specifications
ATF Test team No Test the system to ensure that it is suitable for use

2.3. Business Goals

ATF system allows to automatize SDL regression testing and decreasing functional end regression costs.
ATF with a smoke tests scripts suite provide Continuous testing and Continuous delivery for SDL open-source developers and integrators.

2.4. Significant Driving Requirements

The requirements are listed in the table below and ordered by descending of their significance from architectural solution point of view.

# Driving Requirement Description
1. ATF has to be POSIX-compliant to be easily ported on all POSIX standardized OSs.
2. Script language need to be used as a main-tool for simplification.
3. ATF shall provide a High-level API for SDL manipulation.
