How to use constant property when defining TestParameter in unittest.

A constant class property can be used when defining a content of other class properties (e.g. testConstant1 below).

But when this other property is in the TestParameter property block (e.g. testConstant2) matlab complains that 'The class UnitTestConstantInTestParams has no Constant property or Static method named 'CONST_VALUE''.

    classdef UnitTestConstantInTestParams < matlab.unittest.TestCase

        properties
            testConstant1 = num2cell(1:UnitTestConstantInTestParams.CONST_VALUE);
        end

        properties (Constant)
            CONST_VALUE = 5;
        end

        properties (TestParameter)
            % testConstant2 = num2cell(1:5);
            testConstant2 = num2cell(1:UnitTestConstantInTestParams.CONST_VALUE);
        end

        methods (Test)
            function testConstValues1(testCase)

                for value = testCase.testConstant1
                end
            end

            function testConstValues2(testCase, testConstant2)

            end
        end

    end

Is this a known and desired behavior?

Tested in 8.6.0.267246 (R2015b).

This is a bug:

The bug report mentions Static methods but the same issue applies to Constant properties.

Thanks, that was very helpful, since none of the workarounds I tried worked ;-).
