Microsoft.Data.SqlClient.SqlException : Cannot open database "<DATABASE>" requested by the login. The login failed.

[gabrielbergoc]

.NET version: 7.0

So, when I run the tests in the template, they run just fine, and the integration tests create a "CleanArchitectureDb-Test" in my localdb. But after I adapted the tests to my application, I get

Microsoft.Data.SqlClient.SqlException : Cannot open database "<DATABASE>" requested by the login. The login failed.

Why isn't my project creating the database before the tests, and the template is? I couldn't find a single divergent line of code that might cause this issue...
Or even better: how is the template project creating the database before the tests?
