addTestCaseToTestPlan failed with "xml.parsers.expat.ExpatError: junk after document element: line 1, column 91"

[kennethwork99]

What is the expected behavior with adding existing test cases to test plan? Should it failed with "testlink.testlinkerrors.TLResponseError" instead of xml error? Initially I called addTestCaseToTestPlan and it worked fine. Later on user added new test cases. l was curious what would happen if calling addTestCaseToTestPlan again with existing tests and new tests and found the xml.parsers.expat.ExpatError.

Hello Kenneth,

currently, invalid XML responses from TL are not catch as an TLResponseError.
Invalid XML responses happens when an internal TL failure occurs.

In your case, following invalid xml content is returned it seams, that TL does not catch some db errors for your invalid request

Currently the python client will not catch such TL internal server errors. Please report such internal server errors to TL ( http://mantis.testlink.org/ ) , so that these problems are fixed inside the server.
