One test bench is saved to your current folder:

  • testbench_Echo.m

Input Arguments

collapse all

Options to modify test bench procedure, specified as -nomex or -keeptestbench. Options can be specified together or separately, and in any order.

  • -nomex –– validateAudioPlugin does not generate and run a MEX version of the test bench file. This option significantly reduces run time of the test bench procedure.

  • -keeptestbench –– validateAudioPlugin saves the generated test benches to the current folder.

Name of the plugin class to validate. The plugin class must derive from either the audioPlugin class or the audioPluginSource class. The validateAudioPlugin function exercises an instance of the specified plugin class.

You can specify the plugin class to validate by specifying its class name or file name. For example, the following syntaxes perform equivalent operations:

  • validateAudioPlugin myPlugin

  • validateAudioPlugin myPlugin.m

If you want to specify the plugin class by file name, and your plugin class is inside a package, you must specify the package as a file path. For example, the following syntaxes perform equivalent operations:

  • validateAudioPlugin myPluginPackage.myPlugin

  • validateAudioPlugin +myPluginPackage/myPlugin.m

Limitations

The validateAudioPlugin function is compatible with Windows® and Mac operating systems. It is not compatible with Linux®.

Test Bench Procedure

The validateAudioPlugin function uses dynamic testing to find common audio plugin programming mistakes not found by the static checks performed by generateAudioPlugin. The function:

  1. Runs a subset of error checks performed by generateAudioPlugin.

  2. Generates and runs a MATLAB® test bench to exercise the class.

  3. Generates and runs a MEX version of the test bench.

  4. Removes the generated test benches.

If the plugin class fails testing, step 4 is automatically omitted. To debug your plugin, step through the saved generated test bench.

If you use the -keeptestbench option, or if an error occurs during validation, the test bench files are saved to your current folder.
