@dvamst did you install magento before running tests? tests rely on some CLI commands to clean cache, and some CLI commands do not work unless magento is installed.

[volodymyr-d]

@mazhalai Yes, i did. Magento is installed and frontend is working fine.

[mazhalai]

@dvamst Please try cleaning your root var folder and the tmp directory inside integration tests.

[volodymyr-d]

@mazhalai Done. Still see the same error.

[mazhalai]

@dvamst composer install in root? in addition to above cleaning of folders.

[volodymyr-d]

@mazhalai yes, sure. Frontend is running fine.

[volodymyr-d]

@mazhalai I have reinstalled magento from scratch. Now tests are working. I'll close the issue.
