Dos.ORM
Dos.ORM（原Hxj.Data）于2009年发布、2015年正式开源，支持Core，该组件已在大量成熟项目中应用。初期开发过程中参考了NBear与MySoft，吸取了他们的一些精华，加入新思想，后期参考EF的Lambda语法进行大量扩展。官方网站：https://www.ITdos.com/Dos/ORM/Index.html，交流QQ群：60831381。

TestBase
*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()

```
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 & 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();
```

RulesEngine
Rules Engine is a package for abstracting business logic/rules/policies out of the system. This works in a very simple way by giving you an ability to put your rules in a store outside the core logic of the system thus ensuring that any change in rules doesn't affect the core system.
