Landerist

Open project for the decentralization of real estate listings using the following methodology:

1. Locate websites of real estate agencies by country that may contain property listings.
2. Download the data from the real estate listings and standardize it using artificial intelligence.
3. Distribute the dataset for free in ORELS format.
4. Keep the dataset updated daily.

Installation

Download the project and open it in Visual Studio. Copy appsettings.example.json to appsettings.Local.json and fill in the settings needed by your environment. The local file is ignored by Git and must not be committed.

Settings can also be supplied with environment variables prefixed with LANDERIST__. For example, LANDERIST__DATABASE_NAME overrides DATABASE_NAME from the JSON files. Environment variables take precedence over local JSON settings.

The test runner uses DATASOURCE_LOCAL while sharing the configured database name and user. It refuses to start when DATASOURCE_LOCAL matches DATASOURCE_PRODUCTION.

Open Database.sql, update its local paths, and run it in SQL Server to initialize the database.

Testing

Run the unit tests, which do not require SQL Server, with:

dotnet test .\landerist_unit_tests\landerist_unit_tests.csproj

Run the automated SQL Server integration tests with:

dotnet test .\landerist_integration_tests\landerist_integration_tests.csproj

These tests use only DATASOURCE_LOCAL, run serially, and perform CRUD checks inside a temporary SQL table. The legacy landerist_tests project remains a manual diagnostics runner and is not part of the automated test suite.

Run the architecture fitness tests with:

dotnet test .\landerist_architecture_tests\landerist_architecture_tests.csproj

See ARCHITECTURE.md for the dependency rules and migration baseline.
