@jerneju should we maybe fix CredentialManager.__getattr__ to catch the error and then return an empty string?

This is fixing retrieving from CredentialManager. What about storing into it? Can the same thing happen there?

[jerneju]

@nikicc if we do not plan to show an error message in the future, then fixing CredentialManager is way better. Is there any widget where user really should be informed about this error?

[jerneju]

@nikicc I have finally done the test. It does raise an error when trying to store it.

[nikicc]

This is probably blocked on biolab/orange3#2354 right? If so, we should probably bump the Orange version in requirements?

[nikicc]

These tests cannot run until the new version of Orange is out, since on Text we install Orange through pip. We should at least add something like:

    @unittest.skipIf(LooseVersion(Orange.__version__) < LooseVersion('3.4.3'),
                     'Not supported in versions of Orange below 3.4.3')

or probably even better: move the test to the core Orange.

Closed in favor of biolab/orange3#2354 .
