				raillaAuthorUnsubmitted Done Inline Actions The name is generated by the storage and IRL will never match the original name because it's hashed (which is tested elsewhere) and naming/storing logic is not specific to the avatar in any way. Checking the full name would require mocking the storage and/or the hashing, and it seems out of scope of this change, which should assume that storage just works. I've added a todo https://developer.blender.org/T81290 about configuring test storage in the backlog, because currently it's using the same configuration staging is using, which is not ideal. railla: The name is generated by the storage and IRL will never match the original name because it's…
				sybrenUnsubmitted Not Done Inline Actions Fair enough, but why then bother checking the avatar name at all? sybren: Fair enough, but why then bother checking the avatar name at all?
				raillaAuthorUnsubmitted Done Inline Actions It's just a sanity check: the goal of the test is to test that avatar change is being handled in some meaningful way ("`avatar` used to be empty, check that it's not empty after the webhook was called"). Afaik, the only way to check that a `FileField` is "not empty", is to check either `bool(file_field)` or `file_field.name`, and out of these two I'd prefer the explicit latter one, and just to remind whomever reading the test that it's an image, also check for the extension. railla: It's just a sanity check: the goal of the test is to test that avatar change is being handled…
