Being able to use asynchronous functions in your tests could be useful, for example, when you're querying your database asynchronously. Imagine you want to test sending requests to your FastAPI application and then verify that your backend successfully wrote the correct data in the database, while using an async database library.

Let's look at how we can make that work.

## pytest.mark.anyio { #pytest-mark-anyio }

map:{
    # /- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
    # o database: (Required)
    #  This is the target database, only considered when generating
    #  the SQL for your DBFlute project.
    #  Your possible choices are:
    #
    #    mysql, postgresql, oracle, db2, sqlserver,
    #    h2, derby, (sqlite, firebird, msaccess)
    #
    ; database = h2
    # - - - - - - - - - -/

package gorm

import (
	"context"
	"database/sql"

	"gorm.io/gorm/clause"
	"gorm.io/gorm/schema"
)

// Dialector GORM database dialector
type Dialector interface {
	Name() string
	Initialize(*DB) error
	Migrator(db *DB) Migrator
	DataTypeOf(*schema.Field) string
	DefaultValueOf(*schema.Field) clause.Expression
	BindVarTo(writer clause.Writer, stmt *Statement, v interface{})
	QuoteTo(clause.Writer, string)

    /**
     * Default constructor for UserService.
     */
    public UserService() {
        // Default constructor
    }

    /** User behavior for database operations */
    @Resource
    protected UserBhv userBhv;

    /** Login assistance for authentication operations */
    @Resource
    protected FessLoginAssist fessLoginAssist;

So, you would be able to, for example, share the same data from a Django application in a database with a FastAPI application. Or gradually migrate a Django application using the same database.

And your users would be able to login from your Django app or from your **FastAPI** app, at the same time.
