We used to have browser tests that assert that an edit conflict is detected if the same form is submitted twice. However, for some reasons they did not work in CI, and so they were skipped a long time ago. Quick attempts to fix the underlying problem were not successful (see Reenable browser test to check for edit conflicts (I4df0ff86)).
So, those tests were effectively dead code for a long time and thus deleted: selenium: Delete tests disabled for more than 1 year (I9507e539)
However, we may still wish to verify that behavior.
- there exists a test that asserts that the edit schema form detects an edit conflict when re-submitting the same form
- there exists a test that asserts that the SetEntitySchemaLabelDescriptionAliasesPage detects an edit conflict when re-submitting the same form
