Struct TestDatabase

pub struct TestDatabase<'a, B: DatabaseBackend> {
    pub test_pool: &'a B::Pool,
    pub test_user: String,
}

A test database instance that provides access to a connection pool and test-specific data.

This struct is generic over the database backend type and provides methods for setting up and interacting with a test database instance.

Type Parameters

• 'a - The lifetime of the database pool reference
• B - The database backend type that implements DatabaseBackend

Fields

test_pool: &'a B::Pool

The connection pool for this test database

test_user: String

A unique identifier for the test user, useful for test data isolation

Implementations

impl<'a, B: DatabaseBackend> TestDatabase<'a, B>

pub async fn setup<F, Fut, T>(&self, f: F) -> Result<T, Box<dyn Error>>

where F: FnOnce(B::Connection) -> Fut, Fut: Future<Output = Result<T, Box<dyn Error>>>,

Sets up the test database by executing the provided setup function.

This method acquires a connection from the pool, executes the setup function with that connection, and returns the result.

Type Parameters

• F - The setup function type
• Fut - The future type returned by the setup function
• T - The result type of the setup function

Arguments

• f - A function that takes a database connection and returns a future

Returns

Returns a Result containing the value returned by the setup function, or an error if the setup failed.
