MATLAB Class-based unit tests: How to pass in variable containing data to test

I'm not sure how to pass in variables when executing a unit test. These variables were created from another function not placed within the unit test.

*Method 1:*

       classdef myTest < matlab.unittest.TestCase
              properties
                A, B, C
              end
              methods (Test)
                function testDataCoverage(testCase)
                  expSol = afunction(A, B, C)
                  actSol = 10
                  testCase.verifyEqual(testCase, actSol, expSol)
                end
              end
        end

I next tried to place the variable-creating function (getData) within the unit test but encountered this error:

Concrete class myTest does not define a TestParameter property named BNew for the dataCoverage method. Either implement the property or define the class as Abstract.

*Method 2:*

    classdef myTest < matlab.unittest.TestCase

          properties
          end

          methods (Test)

            function testDataCoverage(testCase)
               [A, B, C] = getData()
               expSol = afunction(A, B, C)
               actSol = 10
               testCase.verifyEqual(testCase, actSol, expSol)
            end

            function [A, B, C] = getData()
                ...code here...
            end

            function Sol = afunction(A, BNew, C)
                ...code here...
            end

          end
    end

Try putting getData and afunction in a separate "methods" section--note, plain "methods", without "(Test)"--that is placed before your "methods (Test)" section
