TestBase.HttpClient.Fake 4.2.0

TestBase – Rich, fluent assertions and tools for testing with heavyweight dependencies: HttpClient, AdoNet, AspNetCore, AspNet.Mvc, Streams, Logging

*TestBase* gives you a flying start with
- fluent assertions that are simple to extend
- sharp error messages
- tools to help you test with “heavyweight” dependencies on
 - AspNetCore.Mvc, AspNet.Mvc 3-5, or WebApi Contexts
 - HttpClient
 - Ado.Net
 - Streams & Logging
- Mix & match with your favourite test runners & assertions.

# TestBase.HttpClient.Fake

```
//Arrange
var httpClient = new FakeHttpClient()
               .SetupGetUrl("https://host.*/").Returns(request=> "Got:" + request.RequestUri)
               
               .SetupGetPath("/uri[Pp]attern/").Returns("stringcontent")
               
               .SetupPost(".*").Returns(response)

               .SetupPost(".*", new byte[]{1,2,3}).Returns(otherResponse)

               .SetupPost(".*", "a=1&b=2")
               .Returns(
                           request => "You said : " + request.Content.ReadAsStringAsync().ConfigureFalseGetResult(),
                           HttpStatusCode.Accepted)

               .Setup(x=>x.RequestUri.PathAndQuery.StartsWith("/this")).Returns(response)
               
               .Setup(x=>x.Method ==HttpMethod.Put)
               .Returns(new HttpResponseMessage(HttpStatusCode.Accepted));

// Act

                                               await i.Content.ReadAsStringAsync()));

           
//Assert
putResponse.StatusCode.ShouldBe(HttpStatusCode.Accepted);
postResponse.ShouldBe(response); // ==> SetupPost(".*").Returns(response) was the first
                                   // matched setup. Setups are tried in first-to-last order.                                            

httpClient.Verify(x=>x.Method ==HttpMethod.Put, "Expected Put, but no matching invocations.");
httpClient.Verify(
                   x=>x.Method ==HttpMethod.Post
                   && x.Content.ReadAsStringAsync().ConfigureFalseGetResult()=="a=1&b=2",
                   "Expected Post a=1&b=2");

httpClient.VerifyAll(); // ==> "Exception : 4 unmatched expectations"

```

### TestBase

Chainable fluent assertions get you to the point concisely.

```
UnitUnderTest.Action()
 .ShouldNotBeNull()
 .ShouldEqualByValueExceptFor(new {Id=1, Descr=expected}, ignoreList )
 .Payload
 .ShouldMatchIgnoringCase("I expected this")
.Should(someOtherPredicate);

.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().ShouldBeOneOf().ShouldNotBeOneOf()
numeric.ShouldBeBetween().ShouldEqualWithTolerance()....GreaterThan....LessThan...GreaterOrEqualTo ...
ienumerable.ShouldAll().ShouldContain().ShouldNotContain().ShouldBeEmpty().ShouldNotBeEmpty() ...
stream.ShouldHaveSameStreamContentAs().ShouldContain()
value.ShouldBe().ShouldNotBe().ShouldBeOfType().ShouldBeAssignableTo()...
.ShouldAll(predicate), .SingleOrAssertFail()...
