Item is gated behind the `mock` feature

I want to create mock data for my database unit tests. However, using #[cfg(feature = "mock")] throws the error:

error[E0432]: unresolved import `crate::tests::prepare_mock_data::prepare_mock_db`
  --> src/tests/user_test.rs:18:9

        .append_query_results([
            vec![
                isumis_user::Model {
                    id: 1,
                    username: "Test".to_string(),
                    pass_hash: encrypted_pass.0,

                    group_id: None,
                    user_role: Role::Student,
                    created_at: Default::default(),
                    modified_at: None,
                }
            ]
        ])
        .into_connection()
}

[features]
mock = ["sea-orm/mock"]

[[test]]
name = "user_test"
path = "src/tests/user_test.rs"
required-features = ["mock"]

[dependencies.sea-orm]
version = "1.1.0"
features = [
    "sqlx-postgres", 
    "runtime-async-std-native-tls", 
    "macros", 
    "runtime-async-std"
]

I want to use the feature on this one function because sea_orm does not allow to use mock for real databases.

The places you call or import prepare_mock_db must also be behind the "mock" feature gate. So in your src/tests/user_test.rs, try configuring out the import:

#[cfg(feature = "mock")]
use crate::tests::prepare_mock_data::prepare_mock_db;

It has to be everywhere where I need this feature....oof :slight_smile:

Maybe you can abstract every test that needs the mock feature into a single module and then feature-gate the module. Then you'd only have two places with #[cfg(feature = "mock")].
