During exploratory tests, I noticed that after one tries to change the user's email address to a faulty one, the error message next to the "Email" field doesn't occur.
Log into the application as administrator.
Go to Administration > Users.
Click the "Edit" button next to any user with an email address, e.g. srmanager1.
Try to change the user's email address to an incorrect one, e.g. "srmanager1@openlmis".
The error message that the email address is incorrect doesn't appear below the "Email" field.
The error message below the "Email" field that the address is incorrect should occur before clicking the "Update User" button.
