FixtureBase 0.3.0

Don't spend hours writing code to mock a dozen dependencies, and more hours debugging it. Just write your test code, and let FixtureBase create the dependencies for you.

FixtureBase constructs your UnitUnderTest to test your codebase end-to-end, with external dependencies auto-faked and automatically injected in just the right place; even constructor dependencies that are several layers deep.

You just write your tests:
```
public class FixtureBaseExample : FixtureBaseWithDbAndHttpFor<AUseCase>
{
   [Fact]
   public void UUTSendsDataToDb()
   {
       var newDatum = new Datum{Id=99, Name="New!" };

       UnitUnderTest.InsertDb(newDatum);

       Db.ShouldHaveInserted("Data",newDatum);
   }

   [Fact]
   public void UUTreturnsDataFromDbQuerySingleColumn()
   {
       var dbData = new[] { "row1", "row2", "row3", "row4"};
       Db.SetUpForQuerySingleColumn(dbData);

       UnitUnderTest.FromDbStrings().ShouldEqualByValue(dbData);
   }

   [Fact]
   public async Task UUTGetHttpReturnsDataFromService()
   {
       var contentFromService = "IGotThis!";
       HttpClient
           .Setup(m => true)
           .Returns(new HttpResponseMessage(HttpStatusCode.OK) {Content = new StringContent(contentFromService)});

       (await UnitUnderTest.GetHttp()).ShouldBe(contentFromService);

       HttpClient.Verify(x=>x.Method==HttpMethod.Get);
   }
}
```
 
The included examples demonstrate FixtureBases for applications which depend on Ado.Net IDbConnections and on HttpClient network connections.
