Drizzle unit test (Vitest)

i m trying to use a second db(db2) for my unit test but its still keep writing into db1 anyone can gv me some guidance or help please?

export const createNewLocationRow = async (
  createNewLocationPayload: ICreateLocation
) => {
  const { name, coordinate } = createNewLocationPayload;
  try {
    const result = await db
      .insert(locations)
      .values({
        name,
        coordinate,
      })
      .returning();
    return result[0];
  } catch (err) {
    console.log(err);
    throw new CustomError(
      "Failed to create new location",
      HTTP_CODES.BAD_GATEWAY
    );
  }
};

export const createNewLocationRow = async (
  createNewLocationPayload: ICreateLocation
) => {
  const { name, coordinate } = createNewLocationPayload;
  try {
    const result = await db
      .insert(locations)
      .values({
        name,
        coordinate,
      })
      .returning();
    return result[0];
  } catch (err) {
    console.log(err);
    throw new CustomError(
      "Failed to create new location",
      HTTP_CODES.BAD_GATEWAY
    );
  }
};

    db,
    pool,
  };
});

// // Apply migrations before each test
beforeEach(async () => {
  await applyMigrations();

// Clean up the database after each test
afterEach(async () => {
  await db.execute(sql`drop schema if exists public cascade`);
  await db.execute(sql`create schema public`);
