This test validates the service's ability to: - Correctly orchestrate interactions between repositories and mocked external clients. - Process data from mocked analytics providers (for provider-driven metrics). - Execute real MongoDB aggregation pipelines against seeded fixture data (for database-driven metrics). - Transform and persist the final `KpiCardData`, `ChartCardData`, and `RankedListCardData` into a real test database. The test utilizes a temporary MongoDB instance for realistic database interaction and `mocktail` to simulate external API responses, ensuring a robust, fast, and reliable verification of the entire analytics ETL process. --- analytics_sync_service_integration_test.dart | 246 +++++++++++++++++++ 1 file changed, 246 insertions(+) create mode 100644 analytics_sync_service_integration_test.dart diff --git a/analytics_sync_service_integration_test.dart b/analytics_sync_service_integration_test.dart new file mode 100644 index 0000000..873ce9d --- /dev/null +++ b/analytics_sync_service_integration_test.dart @@ -0,0 +1,246 @@ +import 'package:core/core.dart'; +import 'package:data_client/data_client.dart'; +import 'package:data_mongodb/data_mongodb.dart'; +import 'package:data_repository/data_repository.dart'; +import 'package:flutter_news_app_api_server_full_source_code/src/config/environment_config.dart'; +import 'package:flutter_news_app_api_server_full_source_code/src/models/models.dart'; +import 'package:flutter_news_app_api_server_full_source_code/src/services/analytics/analytics.dart'; +import 'package:logging/logging.dart'; +import 'package:mocktail/mocktail.dart'; +import 'package:mongo_dart/mongo_dart.dart'; +import 'package:test/test.dart'; + +class MockAnalyticsReportingClient extends Mock + implements AnalyticsReportingClient {} + +/// A test-specific subclass of AnalyticsSyncService that allows injecting +/// mocked clients. +class TestableAnalyticsSyncService extends AnalyticsSyncService { + TestableAnalyticsSyncService({ + required super.remoteConfigRepository, + required super.kpiCardRepository, + required super.chartCardRepository, + required super.rankedListCardRepository, + required super.userRepository, + required super.topicRepository, + required super.reportRepository, + required super.sourceRepository, + required super.headlineRepository, + required super.engagementRepository, + required super.appReviewRepository, + required super.analyticsMetricMapper, + required super.log, + required AnalyticsReportingClient?

It pulls behavioral data from your chosen analytics provider (Google Analytics or Mixpanel) and combines it with operational data by running direct, complex aggregations against the application's own database. - **High-Performance Dashboard:** The web dashboard reads this pre-aggregated data, resulting in near-instant load times for all analytics charts and metrics. This architecture avoids slow, direct, on-the-fly queries from the client to the analytics provider. - **Provider-Agnostic Design:** The engine is built on a provider-agnostic interface. You can switch between Google Analytics and Mixpanel via a simple configuration change, without altering any code. - **Extensible & Scalable:** Adding new charts or KPIs is as simple as defining a new mapping. The system is designed to be easily extended to track new metrics as your application evolves. -> **Your Advantage:** Get a complete, production-grade analytics pipeline out of the box.
