Dubstep.TestUtilities.TestServer 0.0.4

TestServer

TestServer is designed for unit test. It generates an HttpClient instance that you can inject to your service.

Get Started

1. Install the package by nuget

   dotnet add package Dubstep.TestUtilities.TestServer
   

2. Create a TestServer instance by new TestServer()
3. Configure RuleSet of the TestServer instance
4. Generate a HttpClient by CreateClient()

Example

// The default vaule when not match found is a HttpNotFound response
// It can be changed by SetDefaultAction
server.CurrentRuleSet
    .SetDefaultAction(async (response) =>
    {
        response.StatusCode = 500;
        await response.WriteAsync("Simon says server error");
    });

// Return OK response for every request
server.CurrentRuleSet
    .AddRule()
    .SetOkResponse("ok");

// Return Bad Request for every request
server.CurrentRuleSet
    .AddRule()
    .SetBadRequest();

// Return OK response for every HTTP GET request
server.CurrentRuleSet
    .AddRule()
    .WhenGet()
    .SetOkResponse("ok");

// Return OK response for every HTTP Get request that matches an url patter
var urlPattern = "\\?id=1";
server.CurrentRuleSet
    .AddRule()
    .WhenUrlMatch(urlPattern)
    .SetOkResponse("ok")

// Return OK response for every HTTP request that has expected header
server.CurrentRuleSet
    .AddRule()
    .WhenHeaderMatch("User-Agent", expectedUserAgent)
    .SetOkResponse("ok");

// You can chain your configuration, if the request matches mutiple rules, the first match will be picked
var firstPattern = "\\?id=1";
var secondPattern = "\\?id=*";

server.CurrentRuleSet
    .AddRule()
    .WhenUrlMatch(firstPattern)
    .SetOkResponse("ok-1")
    .AddRule()
    .WhenUrlMatch(secondPattern)
    .SetOkResponse("ok-2");

// Expire the rule after a certain count of match, once the rule has expired, it will never match a request
server.CurrentRuleSet
    .AddRule()
    .SetMaxMatchCount(1)
    .SetOkResponse(okResponse);

// Return Ok response on the first request, and Ok response with a different content on the second request
server.CurrentRuleSet
    .AddRule()
    .SetMaxMatchCount(1)
    .SetOkResponse("ok-1");
    .AddRule()
    .SetOkResponse("ok-2");

// Generate a HttpClient instance
var httpClient = server.CreateClient();

// Apply a HttpMessageHandler to the client
var httpClient = server.CreateClient(new AddAuthorizationHandler());
