mock_adapter library

MockAdapter - Testing adapter for unit and integration tests

This adapter provides a mock implementation of the NetworkAdapter interface, allowing you to test your application without making real network requests.

Features

Configure mock responses for specific paths
Simulate network errors
Add artificial delays
Track request history
No external dependencies required

Usage

import 'package:rxnet_plus/adapters/mock_adapter.dart';
import 'package:rxnet_plus/src/adapter/models/adapter_response.dart';
import 'package:rxnet_plus/src/adapter/models/adapter_request.dart';

void main() {
  test('should fetch user data', () async {
    // Arrange
    final mockAdapter = MockAdapter();
    mockAdapter.setMockResponse(
      '/users/123',
      AdapterResponse(
        statusCode: 200,
        data: {'id': 123, 'name': 'John'},
        headers: {},
        request: AdapterRequest(
          baseUrl: 'https://api.example.com',
          path: '/users/123',
          method: HttpMethod.get,
        ),
      ),
    );

    await rxNet.initNet(
      baseUrl: 'https://api.example.com',
      adapter: mockAdapter,
    );

    // Act
    final result = await rxNet.getRequest()
        .setPath('/users/123')
        .request();

    // Assert
    expect(result.isSuccess, true);
    expect(result.value['name'], 'John');
    expect(mockAdapter.requestHistory.length, 1);
  });
}

Advanced Features

Simulating Errors

mockAdapter.setMockError(
  '/users/123',
  AdapterException(
    type: AdapterExceptionType.notFound,
    message: 'User not found',
  ),
);

Adding Delays

mockAdapter.setMockDelay('/users/123', Duration(seconds: 2));

Tracking Requests

final history = mockAdapter.requestHistory;
expect(history.length, 3);
expect(history[0].method, HttpMethod.get);
expect(history[0].path, '/users/123');
