MEF creates trouble for integration tests #392
Description
I have to fight with MEF on my sever run of unit / integration tests. I have got past not finding the Ado provider with the code sample below but then run up against "SimpleDataException:
Simple.Data.SimpleDataException: No System.Data.SqlClient Provider found.. at Simple.Data.MefHelper.Compose[T](String contractName)"
Would rather have feature that allows me to circumvent MEF for testing.
[ClassInitialize]
public static void ClassInitialize(TestContext testContext)
{
//Hack to avoid strange error that only occurs on automatic test server.
//Error message: Simple.Data.SimpleDataException: No Ado Provider found. at Simple.Data.MefHelper.Compose[T](String contractName)
var adoAdapter = new AdoAdapter();
adoAdapter.Setup(new
{
ConnectionString = "Data Source=(local);Initial Catalog=DB;Integrated Security=True;User Instance=False",
ProviderName = "System.Data.SqlClient"
});
Database.UseMockAdapter(adoAdapter);
}
I have, of course, added all nuget packages to the test project.
