Fix gitlab migration unit test Closes #1837. The differences in dates can be explained by commite19b9653ea
, which changed the order in which "created_date" and "updated_date" are considered. (cherry picked from commitb0bba20aa4
) Mock HTTP requests in GitLab migration test This introduces a new utility which can be added to other tests making HTTP calls to a live service, to cache the responses of this service in the repository. (cherry picked from commit52053b1389
) Enable mocked HTTP responses for GitLab migration test (cherry picked from commit19cefc4de2
) Simplify HTTP mocking utility in unit tests Follow-up to https://codeberg.org/forgejo/forgejo/pulls/1841 (cherry picked from commitca517c8bb4
) (cherry picked from commitb227e0dd6b
) (cherry picked from commit6cc9d06556
) (cherry picked from commitf0746e648d
) (cherry picked from commit414193341b
