ADO.NET Specification Tests

This library provides a suit of xUnit.net-based tests for ADO.NET providers, i.e., classes that inherit from DbConnection, DbCommand, DbDataReader, etc.

It intends to clarify ambiguous areas in the ADO.NET documentation and help ensure that various providers act consistently (when the behaviour doesn't depend on the specific target database server).

How to Use

Add a reference to the NuGet package to your test project.

Create a class that implements IDbFactoryFixture: the Factory property must return a DbProviderFactory for your ADO.NET implementation, and the ConnectionString property must return a valid connection string that the test suite can use to connect to a database. See this example for System.Data.SqlClient.

To use the tests that execute SQL statements, you must implement the ISelectValueFixture interface. Examples of doing this can be found in the tests/* projects and AdoNet.Databases.

Create one public derived class from each XTestBase<T> test base class. Add a public constructor that takes an instance of your IDbFactoryFixture implementation and passes it to the base class.

As necessary, override failing test methods to customize/skip them for your provider.

How to Build a Comparison Chart

Clone this repo.

Run the required database servers locally:

cd docker
docker-compose up

Run the AdoNetApiTest program:

1. In Visual Studio 2017, set it as the Start Up Project and press Ctrl+F5 to launch, or
2. From a command prompt: dotnet run -p src\AdoNetApiTest\AdoNetApiTest.csproj

Note that some DB providers require the full .NET Framework 4.7; this program has only been tested on Windows (not with mono).

The program will run all providers' test suites, then open the results in your default browser.
