AlfieCloud includes hundreds of pre-created templates that you can use again and again. You can also modify these templates to suit your needs.
When you use the Create Tests feature you are effectively creating a template. You can use this created template again and again, as you would with the pre-created ones, modifying and publishing it as you need.
A template becomes a test when you publish it. By publishing a template you are saying that you are happy with your selection and it is ready to be taken. You cannot then modify a published test.
If you decide you need to modify a published test, you can simply return to the template, modify it, re-save and republish it with a different test title.
