classdef PlotlyTestCaseAnyInteger < PlotlyTestCaseAny

% PlotlyTestCaseAnyInteger Matcher for integer values

%

% This class validates that a value is an integer (whole number).

% Optionally can enforce positive integers only.

%

% Do not instantiate this class directly. Use PlotlyTestCase.AnyInteger() instead.

%

% Example:

% expected.width = PlotlyTestCase.AnyInteger();

% testCase.verifyEqualStructs(actual, expected);

properties

PositiveOnly = false % If true, only accept positive integers

end

methods

function obj = PlotlyTestCaseAnyInteger(positiveOnly)

% Constructor

%

% Syntax:

% obj = PlotlyTestCaseAnyInteger()

% obj = PlotlyTestCaseAnyInteger(positiveOnly)

%

% Input:

% positiveOnly - (Optional) If true, only accept positive integers

if nargin > 0

obj.PositiveOnly = positiveOnly;

end

end

function result = match(obj, actualValue)

% match Check if value is a valid integer

%

% Validates that actualValue is a numeric integer value.

% If PositiveOnly is true, also checks that value > 0.

result = struct('passed', false, 'diagnostic', '');

% Check if it's numeric

if ~isnumeric(actualValue)

result.diagnostic = sprintf('Expected integer, got %s', class(actualValue));

return;

end

% Check if it's scalar

if ~isscalar(actualValue)

result.diagnostic = sprintf('Expected scalar integer, got %s array', mat2str(size(actualValue)));

return;

end

% Check if it's a whole number

if actualValue ~= floor(actualValue)

result.diagnostic = sprintf('Expected integer, got %g', actualValue);

return;

end

% Check if positive (if required)

if obj.PositiveOnly && actualValue <= 0

result.diagnostic = sprintf('Expected positive integer, got %d', actualValue);

return;

end

result.passed = true;

end
