Verify Requirements by Using Tests
Link requirements to tests in MATLAB and Simulink, then verify the requirements by running the tests. Track the verification status of requirements, and justify requirements that cannot or do not need to be verified. Use external results to verify requirements.
Apps
| Requirements Editor | Create and edit requirements |
| Requirements Manager | Manage requirements and links in model |
Classes
Methods
Topics
- Verify and Validate a Model and Code
Define requirements, test models and code, check for design errors and standards compliance, and measure test coverage.
- Review Requirements Verification Status
Use the requirements verification status to check test and analysis results linked to your requirements.
- View Unified Verification Results in Model Testing Dashboard and in Requirements Editor
Use the Model Testing Dashboard to visualize the requirements verification status of requirements in your projects. (Since R2024a)
- Verify Requirements with MATLAB Tests
Verify requirements by running linked MATLAB tests. (Since R2022a)
- Link Test Cases to Requirements
Associate Simulink Test™ test cases with requirements.
- Generate and Export Tests from Requirements Table Blocks
Automate test generation and execution in models that contain Requirements Table blocks.
- Justify Requirements
Provide justifications for your requirements.
- Include Results from External Sources in Verification Status
Link from external sources and display the results in the requirements verification status.
Featured Examples

Linking to a Test Script
Link a requirement to a MATLAB script.
Linking to a Result File
Link a requirement to a test result file.
Integrating Results from a Custom-Authored MATLAB Script as a Test
In this example, you link a requirement to a MATLAB® script. The verification status in the Requirements Editor reflects the test results. This example performs the steps described in Linking to a Test Script. This example uses a requirements set file named counter_req.slreqx, a MATLAB script called runmytests.m that runs a test for the Counter class in Counter.m. The test script contains custom methods that write results a TAP format to a file named results.tap.
Integrating Results from an External Result File
In this example, you link a requirement to a result file in Excel® Format. The verification status in the Requirements Editor reflects the test results. This example performs the steps described in Linking to a Result File. This example uses a requirement set file named counter_req and a test results file named results.xlsx. This file contains a test case named counterSetsValue.
Integrating Results from a Custom Authored MUnit Script as a Test
In this example, you integrate the results from a MATLAB® xml Unit test by linking to a test script. The verification status in the Requirements Editor reflects the test results. This example uses a requirement set file named counter_req and an XML unit test file named myMUnitResults.xml. This file contains a test case named testCounterStartsAtZero.
