You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: ColorSelector.m
    path of file: ./repos/widgets-toolbox/test/+wt/+test
    
    the code of the file until where you have to start completion: classdef 
    
function
        
    end %methods
    
    
    %% Unit Tests
    methods (Test)
            
        function testValueProperty(testCase)
            
            % Set the color
            newColor = [1 0 0];
            testCase.verifySetProperty("Value", newColor);
            
            % Set the color
            newColor = [0.5 1 0];
            testCase.verifySetProperty("Value", newColor);
            
            % Test an invalid color
            newColor = [-1 0 1];
            errorID = 'wt:validators:mustBeBetween';
            testCase.verifySetPropertyError("Value", newColor, errorID);
            
            % Test an invalid color
            newColor = {1};
            errorID = 'MATLAB:validation:UnableToConvert';
            testCase.verifySetPropertyError("Value", newColor, errorID);
            
            % Test an invalid color
            newColor = rand(1,5);
            errorID = 'MATLAB:validation:IncompatibleSize';
            testCase.verifySetPropertyError("Value", newColor, errorID);
