Is there a way to change order of TestCases in sltest.tes​tmanager.T​estSuite programmatically?

I'm importing content of a TestFile from external server. Everything works well, but there is a case, when order of the TestCases changes, and I want to refrect it in the parent sltest.testmanager.TestSuite.

I thought that sltest.testmanager.moveTests might be helpful, as it accepts array of objects to be moved, and moving those testcases to a temporary TestSuite, then back to the original place. Unfortunately order of the array doesn't seem to be respected - testcases are landing in their original order.

            % sort test cases within this test suite
            unsortedTCs = parentTS.getTestCases();
            if ~isempty(unsortedTCs)
                % collect the indexes of the referred testcases
                sorting_array = getOriginalIndexes(unsortedTCs);
                [~, ind] = sort(sorting_array);
                sortedTCs = unsortedTCs(ind);
                tempTestSuite = createTestSuite(parentTS, 'temp');
                sltest.testmanager.moveTests(sortedTCs, tempTestSuite);
                sltest.testmanager.moveTests(sortedTCs, parentTS);
                remove(tempTestSuite);
            end

Any hint?

In UI I can drag&drop testcases to change their order - looking for similar functionality over API.

Thank you!

You can use the moveTest api’s starting with R2020b release to move tests with the following. We will request the documentation to be update with this example

sltest.testmanager.moveTests(tc1, tc2); % move tc1 below tc2
sltest.testmanager.moveTests(tc3, tc1); % move tc3 to top before tc1

I am using R2024A and finding that if I have test manager open when I run the commands, then the test suites are ordered as I want them, but upon reload then the order has changed. Is there anything in the background that could cause Test Suites to be re-ordered to a different criteria?

Why does the order of your tests matter? That sounds like you may have Interacting Tests, a sub-category of the Erratic Tests test smell.
