Release Notes
v2.0.0
Developed with a help of @jogibear9988, @dzmitry-lahoda, @MaceWindu,
and other contributors - kudos to all of them!

- added: #107 Check if xxxAssigns also work with Variables
- added: #118 Support for Expression.Variable (in a Expression.Block)
- added: #127 Switch is not supported
- added: #130 Net Framework Expression compiler generates perfromanter Code for isNull check
- added: #138 Optimize Compilation of nested Lambdas
- fixed: #83 Issues with linq2db tests

- fixed: #137 Problem with Reading & Writing of Struct Fields.
- fixed: #146 Boolean parameter value changed from false to true
- fixed: #147 'Common Language Runtime detected an invalid program' with int.TryParse
- fixed: #151 'Attempt to read protected memory'
- fixed: #152 int.MinValue access throws 'Method not supported'
- fixed: #154 Equals Expression does not call "Equals" of class (in MS Code)
- fixed: #156 Invoking an Action constant fails with 'Common Language Runtime detected an invalid program'
- fixed: #159 Condition with converted numeric comparisons gives unexpected result
- fixed: #162 Float - short numeric comparisons with conversions gives unexpected result
- fixed: #163 Add of Nullable Int, etc does not work correctly

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()
.ShouldNotBeNullOrEmptyOrWhiteSpace().ShouldEqualIgnoringCase()
.ShouldContain().ShouldStartWith().ShouldEndWith().ShouldBeContainedIn(), ...

```
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();
```
