import 'dart:io';

import 'package:isar/isar.dart';
import 'package:todos/todo.dart';

void main() {
  // TODO Implement typical setup
  //  TODO Send boilerplate isar test snippet to @brian-at-pieces

// Note: This code is setting up a test environment
// using an in-memory Isar database. It creates a new Todo object,
// adds test data to the object, and then writes the data to the database.
// This is useful for testing the functionality of an Isar database without
// affecting the real data used by an application.

// Initialize an Isar instance
  late final Isar isar;

// Set up test environment
  setUp(() async {
    // Configure in-memory database, but this can be changed to a file location
    isar = await Isar.open(
      [TodoSchema],
      directory: Directory.current.path,
    );

    // Add test data
    final newTodo = Todo()
      ..done = false
      ..title = 'Task 1'
      ..description = 'This is task 1'
      ..created = DateTime.now()
      ..updated = DateTime.now();

    // Write new data to Isar database
    await isar.writeTxn(() async {
      await isar.todos.put(newTodo);
    });
  });

// Classic tearDown method for isar
  tearDown(() async {
    await isar.close();
  });

  test('Add and retrieve todo', () async {
    // Retrieve the test data and assert that it matches the original data
    final existingTodo = await isar.todos.get(1);
    expect(existingTodo?.title, equals('Task 1'));
    expect(existingTodo?.done, equals(false));
  });

  test('Delete todo', () async {
    // Delete the test data and assert that it no longer exists
    await isar.writeTxn(() async {
      await isar.todos.delete(1);
    });

    final existingTodo = await isar.todos.get(1);
    expect(existingTodo, isNull);
  });
}
