Testing

If you’re using ent.Client in your unit-tests, you can use the generated enttest package for creating a client and auto-running the schema migration as follows:

package main
import (
    "testing"
    "<project>/ent/enttest"
    _ "github.com/mattn/go-sqlite3"
)
func TestXXX(t *testing.T) {
    client := enttest.Open(t, "sqlite3", "file:ent?mode=memory&_fk=1")
    defer client.Close()
    // ...
}

In order to pass functional options to Open, use enttest.Option:

func TestXXX(t *testing.T) {
    opts := []enttest.Option{
        enttest.WithOptions(ent.Log(t.Log)),
        enttest.WithMigrateOptions(migrate.WithGlobalUniqueID(true)),
    }
    client := enttest.Open(t, "sqlite3", "file:ent?mode=memory&_fk=1", opts...)
    defer client.Close()
    // ...
}
