*TestBase* gives you a flying start with - fluent assertions that are easy to extend - sharp error messages - tools to help you test with “heavyweight” dependencies on - AspNetCore.Mvc, AspNet.Mvc or WebApi Contexts - HttpClient - Ado.Net - Streams & Logging - Mix & match with your favourite test runners & assertions. ``` UnitUnderTest.Action() .ShouldNotBeNull() .ShouldEqualByValueExceptFor(new {Id=1, Descr=expected}, ignoreList ) .Payload .ShouldMatchIgnoringCase("I expected this") .Should(someOtherPredicate); .Items .ShouldAll(predicate) .ShouldContain(item) .ShouldNotContain(predicate) .Where(predicate) .SingleOrAssertFail() .ShouldEqualByValue().ShouldEqualByValueExceptFor(...).ShouldEqualByValueOnMembers() work with all kinds of object and collections, and report what differed. string.ShouldMatch(pattern).ShouldNotMatch().ShouldBeEmpty().ShouldNotBeEmpty() .ShouldNotBeNullOrEmptyOrWhiteSpace().ShouldEqualIgnoringCase() .ShouldContain().ShouldStartWith().ShouldEndWith().ShouldBeContainedIn(), ... numeric.ShouldBeBetween().ShouldEqualWithTolerance()....GreaterThan....LessThan...GreaterOrEqualTo ... ienumerable.ShouldAll().ShouldContain().ShouldNotContain().ShouldBeEmpty().ShouldNotBeEmpty() ... stream.ShouldHaveSameStreamContentAs().ShouldContain() value.ShouldBe().ShouldNotBe().ShouldBeOfType().ShouldBeAssignableTo()... ``` TestBase.HttpClient.Fake ``` new FakeHttpClient() .Setup(x=>x.RequestUri.PathAndQuery.StartsWith("/this")) .Returns(response) .Setup(x=>x.Method==HttpMethod.Put) .Returns(new HttpResponseMessage(HttpStatusCode.Accepted)); ``` TestBase.AdoNet ------------------ `FakeDbConnection` ``` - db.SetupForQuery(…) - db.SetupForExecuteNonQuery(…) - db.ShouldHaveUpdated("tableName", …) - db.ShouldHaveSelected("tableName", …) - db.ShouldHaveDeleted("tableName", …) - db.Verify( x=>x.CommandText.Matches("Insert [case] .*") && x.Parameters["id"].Value==1 ) - db .ShouldHaveInvoked(cmd => predicate(cmd)) .ShouldHaveParameter("name", value) ``` `RecordingDbConnection` TestBase.Mvc.AspNetCore & TestBase.Mvc for Mvc 4 & Mvc 5 -------------------------------------------------------- ``` ControllerUnderTest.WithControllerContext() .Action() .ShouldbeViewResult() .ShouldHaveModel<TModel>() .ShouldEqualByValue(expected) ControllerUnderTest.Action() .ShouldBeRedirectToRouteResult() .ShouldHaveRouteValue("expectedKey", [Optional] "expectedValue"); ShouldHaveViewDataContaining(), ShouldBeJsonResult() etc. ``` - Test AspNetCore controllers with zero setup using `controllerUnderTest.WithControllerContext(actionUnderTest)` - Test more complex AspNetCore controller/application dependencies using `HostedMvcTestFixtureBase` and specify your MVCApplications `Startup` class. ``` [TestCase("/dummy")] public async Task Put_Should_ReturnA(string url) { var httpClient=GivenClientForRunningServer<Startup>(); GivenRequestHeaders(httpClient, "CustomHeader", "HeaderValue1"); var result = await httpClient.PutAsync(url, json); result.ShouldBe_202Accepted(); } ``` For Mvc4 and Mvc 5, fake your http request &amp; context, and use the `RegisterRoutes` method of your actual application to set up `Controller.Url` ``` ControllerUnderTest .WithHttpContextAndRoutes( RouteConfig.RegisterRoutes, "/incomingurl" ); ApiControllerUnderTest.WithWebApiHttpContext<T>( httpMethod, requestUri, routeTemplate) ``` Testable Logging ``` // Extensions.Logging.ListOfString var log = new List<String>(); ILogger mslogger= new LoggerFactory().AddStringListLogger(log).CreateLogger("Test2"); // Serilog.Sinks.ListOfString Serilog.Logger slogger= new LoggerConfiguration().WriteTo.StringList(log).CreateLogger(); ```

TestBase.AdoNet TestBase.FakeDb ------------------ Fake and verify AdoNet queries and commands ``` - fakeDbConnection.SetupForQuery(IEnumerable<TFakeData>; ) - fakeDbConnection.SetupForQuery(IEnumerable<Tuple<TFakeDataForTable1,TFakeDataForTable2>> ) - fakeDbConnection.SetupForQuery(fakeData, new[] {"FieldName1", FieldName2"}) - fakeDbConnection.SetupForExecuteNonQuery(rowsAffected) - fakeDbConnection.ShouldHaveUpdated("tableName", [Optional] fieldList, whereClauseField) - fakeDbConnection.ShouldHaveSelected("tableName", [Optional] fieldList, whereClauseField) - fakeDbConnection.ShouldHaveUpdated("tableName", [Optional] fieldList, whereClauseField) - fakeDbConnection.ShouldHaveDeleted("tableName", whereClauseField) - fakeDbConnection.ShouldHaveInvoked(cmd => predicate(cmd)) - fakeDbConnection.ShouldHaveExecutedStoredProcedure("name") - fakeDbConnection.ShouldHaveXXX().ShouldHaveParameter("name", value) - fakeDbConnection.Verify(x=>x.CommandText.Matches("Insert [case] .*") && x.Parameters["id"].Value==1) ``` TestBase.RecordingDb -------------------- * `new RecordingDbConnection(IDbConnection)` helps you profile Ado.Net Db calls See also - TestBase - TestBase.Mvc - TestBase.AdoNet - Serilog.Sinks.ListOfString - Extensions.Logging.ListOfString
