Create a test-specific simulation environment for your model by using a test harness. You can isolate individual blocks for unit testing and add inputs, verification logic, and dashboard blocks. Perform closed-loop testing by adding physical plant models to the test harness. Test potential design changes in the test harness before you change the production model.
Compared to using separate models for unit testing, test harnesses offer management and synchronization capabilities in the model canvas. If your model is under change management, you can save test harnesses in external files, without changing the main model.
You can test generated code by simulating test harnesses in SIL or PIL mode. You can also test external handwritten code by creating test harnesses for C Caller or S-Function blocks.
|Model and code testing in different execution environments, manage test suites, and analyze and report results
- Test Harness and Model Relationship
Test a Simulink® model in an isolated environment, using a separate workspace and configuration set accessed via the model canvas.
- Create a Test Harness
Use a test harness to isolate the component under test.
- Create or Import Test Harnesses and Select Properties
Create, import, and customize test harness configurations for your model and subsystem.
- Manage Test Harnesses
Manage test harnesses, including opening, converting, closing, deleting, and exporting.
- Synchronize Changes Between Test Harness and Model
Transfer configuration sets and workspace variables, update the component design, and rebuild the harness to reflect the latest design.
- Test Harness Construction for Specific Model Elements
Describes how test harnesses are constructed for certain Simulink semantics and component types.
- Test Library Blocks
Test reusable components using tests for libraries, library blocks, and linked blocks.
- Customize Test Harnesses
Create reusable functions and callbacks that customize test harnesses.
- Create Test Harnesses from Standalone Models
Import standalone models as test harnesses in Simulink Test™.
- Use Stateflow Chart for Test Harness Inputs and Scheduling
Use Stateflow Chart to define test harness inputs and test sequence.
