Is it possible to do front-end development without having a database at hand?

Question

Stored procedures

Question for web-developers: is it possible to create front-end and back-end of the site if you have a detailed technical specification without having a database at hand that stores the content and interface description?
For example, MS SQL Server is used as a database server, communication with the database is based on stored procedures, procedure parameters and returned data sets are specified in the TOR.
I apologize for the clumsiness in the wording.
Please answer to the point.

Answer 1

Front-end is possible (it does not communicate directly with the database in your case)
What prevents you from creating a test database for tests?

Answer 2

Fixtures

Answer 3

Maybe use sqlite as a test database?

Answer 4

you can lock the data source and use fixtures for the data itself, as index0h said , but then you need to clearly know the interface with which the production application will communicate
