Getting “NameError: 'aqFileSystem' is not defined” after upgrading to TestComplete v15.77.6.7 (x64).

Hi dhanuj,

If you have verified by rolling a system back to the previous version open a support issue and create a very simple project to demo and test the problem with support.  You can start a case from the help menu in TestComplete.  I am on an older version and I haven't seen any community posts related to this.  That said version upgrades can cause unexpected issues so I always check and test before I trust it. 😉

Post back and let us know what you find out.  The community would be grateful.  

... If you find my posts helpful drop me a like! 👍 Be sure to mark or post the solution to help others out and/or to credit the one who helped you. 😎

... Also, the version history page is a great resource to check to see if you really even need to upgrade.  There isn't anything in the release notes for this version specifically related to this issue that I saw.

It's a know issue in the latest version of TestComplete with Python. I do suggest you raise a support ticket though.

We extensively use aqFileSystem in our Javascript codebase, and v15.77.6.7 doesn't cause issues for us. I believe this may be an issue specifically with v15.77.6.7 in combination with a Python codebase, and seems related to:
NameError: name 'Aliases' is not defined | SmartBear Community

If you're using Python, please double-check that your project is running with Python 3.13.3, which is the supported version in TestComplete v15.77.6.7. A mismatch could cause issues like missing built-in objects.

Also, a potential workaround was mentioned in this post — try adding the following to your OnStartTestEvent handler:

import gc
def OnStartTestEvent(Sender):
    gc.collect()

This forces garbage collection before your tests run and helped resolve similar issues with built-in objects.
