TestSuite Maximum recursion limit reached.

Hi

I wrote a testSuite for my application. Unfortunately, there is a recursion occurring which I cannot explain. The image below depicts the folder structure I use.

The next lines of code is where I initiate the TestSuite. I assured that my current working directory is ./test.

% MainTest.m
import matlab.unittest.TestSuite

suiteFolder = TestSuite.fromFolder(pwd);
result = run(suiteFolder);

disp(result)

As an example below is the code which runs one test function.

% TestStage.m
function tests = TestStage
tests = functiontests(localfunctions);

function setupOnce(testCase)
testCase.TestData.origPath = pwd;
cd('../src')

function teardownOnce(testCase)
cd(testCase.TestData.origPath);

function testSmallStage(testCase)

    verifyTrue(testCase, true);

I get the following error when I run the `MainTest.m`. However, the test finishes when I run `TestStage.m` on its own.

Warning: The following error was caught while executing 'matlab.unittest.internal.Teardownable' class destructor:
Maximum recursion limit of 500 reached.

Can you reproduce the error? Where is my mistake?
