FixtureBase
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. - To create your own FixtureBase with your own preferred Fakes, see the examples at <https://github.com/chrisfcarroll/ActivateAnything/blob/master/FixtureBase/FixtureExample.cs.md> - For how it's done, see <https://github.com/chrisfcarroll/ActivateAnything/blob/master/FixtureBase/FixtureBase.cs> Construction is done by - [ActivateAnything](https://www.nuget.org/packages/ActivateAnything)   Faking is done by - [TestBase.AdoNet](https://www.nuget.org/packages/TestBase.AdoNet) - [TestBase.HttpClient.Fake](https://www.nuget.org/packages/TestBase.HttpClient.Fake) For more tools focussed on cutting the cost of unit testing, see also: - [TestBase](https://www.nuget.org/packages/TestBase) - [TestBase.AspNetCore.Mvc](https://www.nuget.org/packages/TestBase.AspNetCore.Mvc) - [TestBase-Mvc](https://www.nuget.org/packages/TestBase-Mvc) - [TestBase.AdoNet](https://www.nuget.org/packages/TestBase.AdoNet) - [TestBase.HttpClient.Fake](https://www.nuget.org/packages/TestBase.HttpClient.Fake) - [Serilog.Sinks.ListOfString](https://www.nuget.org/packages/Serilog.Sinks.Listofstring) - [Extensions.Logging.ListOfString](https://www.nuget.org/packages/Extensions.Logging.ListOfString)
