Testing - Ent — ContextQMD

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()
	// ...
}
