ECU-TEST is a software tool from Dresden-based TraceTronic GmbH for testing and validating embedded systems .

Since the appearance of the first version of ECU-TEST in 2003, the software has been used as a standard tool in the development of automotive control units and is increasingly being used in the development of construction and agricultural machines as well as in factory automation . The development of the software began as part of the research project "Systematic Control Unit Test" and laid the foundation for the spin-off of TraceTronic GmbH from the Technical University of Dresden .

ECU-TEST is used for the specification, implementation, documentation, execution and evaluation of test cases . Using various test automation methods, the tool ensures that all activities relating to the creation, execution and evaluation of test cases are carried out efficiently.

functionality

methodology

ECU-TEST automates the control of the entire test environment , whereby a wide range of test tools is supported.

Different levels of abstraction for measured variables allow use in different test levels , including within the framework of model in the loop , software in the loop and hardware in the loop as well as in real systems (for example in the vehicle ).

The creation of test cases in ECU-TEST is done graphically and does not require any programming knowledge. Test case descriptions have a generic form and, together with extensive parameterization and configuration options, allow uniform access to all test tools and thus enable tests that have been created once to be easily used over several development phases.

construction

ECU-TEST is divided into four functional areas:

  • Editor and project manager
  • Configurator
  • Drain machine
  • Analyzer and log generator

To create a test case, one or more sequences of test steps and their parameterizations are defined in the editor. Test steps include reading and evaluating state variables of the device under test, manipulating the test environment and executing diagnostic functions and control structures. The project manager is used to organize several test cases.

Further settings for the test object and the test environment can be made in the configurator.

The execution of test cases is carried out by a multi-level process machine. The resulting logging data is collected and forms the basis for creating a test report .

Optional checks of the recorded quantities downstream of the test take place in the analyzer. From the results of the test execution and subsequent checks, the log generator generates a detailed test report, which can be displayed interactively and stored in files and databases.

Interfaces

ECU-TEST offers clearly defined interfaces for extensions and for integration into existing test and validation processes. A large number of test hardware and software are already supported as standard. Additional tools can be connected with little effort using user-defined test steps, plug-ins and Python scripts. Software tools from several test bench computers in distributed test environments can be addressed via a special client-server architecture . A COM interface to other tools, such as test and requirements management , to version management and test case generation integrated be.

ECU-TEST supports the following hardware and software and is based on the following standards:
