 `test-results-simulink-test` | (Optional) Path to export Simulink Test Manager results in MLDATX format. This input requires a Simulink Test license, and is supported in MATLAB R2019a and later.<br/>**Example:** `test-results/results.mldatx`
 `code-coverage-cobertura`   | (Optional) Path to write code coverage report in Cobertura XML format.<br/>**Example:** `code-coverage/coverage.xml`
 `model-coverage-cobertura`  | (Optional) Path to write model coverage report in Cobertura XML format. This input requires a Simulink Coverage™ license, and is supported in MATLAB R2018b and later.<br/>**Example:** `model-coverage/coverage.xml`
+`use-parallel`              | (Optional) Indicator to run tests in parallel, specified as false or true. This input requires a Parallel Computing Toolbox license, and might not be compatible with other options. If incompatible, testing occurs in serial regardless of the value for `use-parallel`.
 
 ## Notes
 * In MATLAB R2019a and later, the **Run MATLAB Tests** action uses  the `-batch` option to start MATLAB noninteractively. Preferences do not persist across different MATLAB sessions launched with the `-batch` option. To run code that requires the same preferences, use a single action.
