MES Test Manager® (MTest)

The Model Test Manager

MTest is the first choice for requirements-based testing of Simulink®, TargetLink®, and Embedded Coder® models, as confirmed by our customers regularly.

MTest automates all test activities for module and integration testing and supports all simulation types, from model-in-the-loop to processor-in-the-loop simulation.


Your MES Test Manager® benefits:

  • Simple and intuitive test case specification with MTCD
  • Automated test evaluation
  • Assessment Framework for test result evaluation
  • Complete documentation of tests and links to requirements
  • Highest degree of test automation
  • Supports TargetLink® as well as Embedded Coder®
  • Traceability and coverage (model, code, requirements, etc.)
  • Requirements-based testing in compliance with ISO 26262 and ISTQB


How MTest supports you:

1. Matlab Integration
Matlab Integration

MTest is fully integrated in MATLAB® and supports releases from R2007b to R2015b.
This allows MTest to access all MATLAB® variables and parameters relevant to model testing.
MTest is specialized for the software testing of implementation models with dSPACE TargetLink®, as well as Embedded Coder® of MathWorks® – multi-project capability being another strength of MTest.

2. Easy import of requirements

MTest imports requirements directly and with ease, whether from a requirements-workbook, or a file. All requirements are checked for their testability in the process. If requirements alter, MTest will indicate the changes.

3. Efficient specification of test cases

We developed a clear and for testers easily comprehensible test case specification language for MTest: MTCD (Model Test Case Design Language). MTCD allows efficient specification of all required signals and test cases to be linked to requirements individually.

If the test case specification requires other methods, it also imports measurement data (ASCII, MAT, Excel), or classification trees by TESTONA/CTE (Berner & Mattner).

4. Automated test execution

Automated test execution is not only a self-evident, but also fundamental component of MTest. It includes test bed generation, model simulation according to input data, and recording results for MIL, SIL, and PIL simulation along with all internal (local) measurement parameters. All fully automated, totally hands-off!
It is up to you to set the pace, or to let MTest do all the tests for you with the convenient batch mode – either way, you are always in control.

5. Automated evaluation of test results

The Assessment Framework is a powerful MTest tool to evaluate test results safely and automatically. This increases test efficiency and makes the detection of possible errors much easier.

The approach to check each requirement on all test sequences provides higher test coverage and thus a reliable assertion regarding the functional quality of your software model. The Assessment Framework thereby provides cost-effective, yet efficient quality assurance.

6. Test coverage and traceability

MTest automatically aggregates all relevant coverage data for requirements, test specifications, code, and model.

The RCT (Requirements, Coverage, Traceability) Framework integrated in MTest links coverage data directly with requirements – this makes the traceability of results possible at any time.

7. Test documentation

The documentation of test results is a top priority for MTest, and it documents literally everything a tester could wish for:

  • Detailed test reports with signal graphics, applied parameters and test results
  • Compact test catalogs for a quick overview of what is essential

MTest even measures test progress and test quality, pointing out areas to quality managers where action is required.
