Telemotive Test Automation

On the fast lane to series production

Telemotive Test Automation (TTA) is an open and easy to use software framework. It enables a flexible and fast creation of test cases for ECUs. Apps, websites, IoT devices, sensors and software can be tested and validated automatically. TTA takes advantage of existing hardware and software tools and is able to fill any gap in the automated toolchain. TTA was developed according to the ISTQB standards and your codes are reusable.
Test automation has never been more user-friendly!

Based on Python 3, the software framework enables the developers to use open source packages and to benefit from an elaborate reporting with clear visualization. Pre-assembled units, sample code and easy-to-apply test case implementations enable a straightforward learning process for new users as well as accelerated development cycles. We continuously develop Telemotive Test Automation at the pulse of the market and offer customized solutions for individual requirements.

Diagnostics and Flash

Unified Diagnostics Services (UDS)
- The UDS Unit contains functions for all specified UDS Services and a class, defining all the constant parameters from the UDS protocol, in a way that the tester does not have to use the raw/hexadecimal values of the parameters.
ISO-TP
- The ISO-TP Unit sends and receives messages via CAN according to the ISO transport protocol (ISO 15765-2)
Open Diagnostic Data Exchange (ODX) support
- The ODX unit provides functions to access PDX-containers and its ODX-F definition files
- Those containers and files can be used to access necessary information about the flash process for a given software container and the flash data itself
Trigger time outs
Flash ECU
- The Flash unit provides the functionality for both partial and complete implementations of a flash-cycle, as well as building blocks for programming test cases at a user-friendly high level, using the UDS-protocol
- It contains classes and functions, built in a way that the tester does not need to have deep knowledge of the UDS-protocol
Example of tests: Flash, Authentication, system, diagnostic, compliance
OEM-specific connections

Interfaces

Ethernet and CAN
- Sending and receiving of messages
- Parsing of message catalogues (e.g. FIBEX)
- OEM specific implementations available
- Ethernet: Diverse protocol implementations and Ethernet specific units
- Diagnostics protocols over CAN
Serial

- Can be used by several clients simultaneously
- Data can be stored by byte
Image- / Frame grabber
- Different image grabbing devices and drivers available
Android Debug Bridge (ADB)
- Provides the basic communication layer between the Android device and TTA
- Controls the connection and provides the basic communication with the Android device
- Simulation of swipes and taps
- Enables app and phone testing
OEM specific tooling and connections
Simulation tools and rest bus simulation
Anything from the Python network
- Integrated packages such as Selenium, Jira/Confluence, …

Supported Hardware Connections

Touch device Robots
Frame grabbers
Bus interfaces
- Hardware interfaces to send and receive bus messages
- i.e. blue PiraT Mini
Programmable power supply units
Data loggers (reading buses i.e. CAN, Ethernet, FlexRay)
Controllable multimeters
Relays
- Provides functions to operate relays on a relay board
- Set relays, get the switching status (ON or OFF) of the relays, toggle and reset with easy commands in the TTA test case e.g. >>> relay.set(on=[2, 4, 8])
- Boards can be connected using various interfaces (serial, USB, Ethernet)
Further hardware products can be added by the user due to the native Python approach of TTA

Adaptable image processing

Images are captured from external frame grabber devices (e.g. Epiphan) or directly via Secure Shell (SSH)
Techniques: image filtering & comparison, icon search, feature matching, video sequence analysis, image inversion, binarisation (OTSU algorithm), contour detection or other methods using OpenCV
Optical Character Recognition (OCR)
- Recognition of text in images to test against reference values
- More than 100 language packages are implemented using Tesseract and Onenote

Audio testing

Validation of recorded audio signals & their quality such as signal tones (i.e. Head Unit), voice control / voice recognition, …
Comparison to reference signal with probability estimation
Transformation of audio signals to frequency area
Check of signal-noise-ratio and total harmonic distortion

Project roles and their TTA features

TTA features have been tailored for the project roles of a test automatization team.
