MATLAB errors attempting to define listener for nonobservable property

In previous releases, you could define a listener for a nonobservable property. MATLAB

silently ignored the listener and did not call the listener callback. With release MATLAB

2014b, attempting to create a listener using event.proplistener or addlistener for

a nonobservable property causes an error.

Compatibility Considerations

If your code used meta-data or the properties function to get a list of all properties

defined by a class, and then assigns listeners to all properties, you should change your

code. Rewrite the code to determine if a given property is observable before assigning

the listener. For example, this code determines which properties of MyClass are

SetObservable or GetObservable.

mc = ?MyClass;

p = findobj(mc.PropertyList,'SetObservable',1,'-or','GetObservable',1)

p contains the meta.property objects for the properties of MyClass that are

SetObservable or GetObservable.

Script-based tests in unit testing framework

The MATLAB unit testing framework now provides script-based writing, execution, and

verification of tests as an alternative to writing function-based or class-based tests. For

more information, see Write Script-Based Unit Tests.

Plugin to report code coverage in unit testing framework

The matlab.unittest testing framework provides a plugin that produces a

code coverage report for MATLAB source code. For more information, see the

matlab.unittest.plugins.CodeCoveragePlugin documentation.

Control logging and verbosity in unit testing framework

Test authors can control the verbosity of logged messages in their tests. To

TestCase or Fixture. To control the verbosity of the output, use a plugin such as
