Use Rhino Mock to report the function that was called

I have a failing testcase that depends on an external module.
I want to use Rhino Mock to generate a report on called functions.
I created a minimal example that illustrates my problem:
using NUnit.Framework;
using Rhino.Mocks;
using System;
namespace StackOverflow_namespace
{
public interface IUsefulService
{
object HiddenAmongManyCalls();
}
public class ThirdPartyBase
{
private int a = 42;
public ThirdPartyBase(IUsefulService service)
{
object liveFastDieYoung = service.HiddenAmongManyCalls();
liveFastDieYoung.Equals(a);
}
}
public class MyParty : ThirdPartyBase
{
public MyParty(IUsefulService service) : base(service)
{
}
}
[TestFixture]
class StackOverflow
{
[Test]
public void Hypothetical()
{
IUsefulService service = MockRepository.GenerateMock<IUsefulService>();
try
{
var party = new MyParty(service);
}
catch(Exception e)
{
string[] calls = MagicallyGetTheCallsThatWereMadeToTheMock();
foreach(var call in calls)
{
//with my visual studio testrunner for nunit 3 I can investigate stored console output
Console.WriteLine(call);
}
Assert.Fail("Excpexted no exception but was '" + e.GetType().Name + "': " + e.Message);
}
}
private string[] MagicallyGetTheCallsThatWereMadeToTheMock()
{
return new[]
{
"This is where I am lost, I do not know how to get the calls from the repository."
};
}
}
}
I tried to find something online without success.
Do Rhino Mocks record all calls and can I access that list?
Edit:
An attempt to verify Expectations did not work since I am looking for calls I did not expect.
I could build a list of calls using GetArgumentsForCallsMadeOn. I can reflect on the Interface. I started on a method for that but I currently fail to see how I can convert a MethodInfo to an Action<T>.
private IEnumerable<string> GetCallsList<Interface>(Interface rhinomock)
{
Type interfaceType = typeof(Interface);
List<MethodInfo> interfaceMethodInfos = new List<MethodInfo>();
List<string> returnInfos = new List<string>();
StringBuilder callbuilder = new StringBuilder();
foreach (var property in interfaceType.GetProperties())
{
interfaceMethodInfos.Add(property.GetGetMethod());
interfaceMethodInfos.Add(property.GetSetMethod());
}
foreach (var method in interfaceType.GetMethods())
{
interfaceMethodInfos.Add(method);
}
foreach (var methodinfo in interfaceMethodInfos)
{
Action<Interface> magic = null; //convert methodinfo into action - still missing
var calls = rhinomock.GetArgumentsForCallsMadeOn(magic); //magic is currently null, here be crash
foreach (var call in calls)
{
bool more = false;
callbuilder.Clear().Append(interfaceType.Name).Append('.').Append(methodinfo.Name).Append('(');
foreach (var parameter in call)
{
if (more){ callbuilder.Append(", "); }
if (null == parameter) { callbuilder.Append("<null>"); }
else { callbuilder.Append(parameter.ToString()); }
more = true;
}
callbuilder.Append(')');
string callInfo = callbuilder.ToString();
returnInfos.Add(callInfo);
}
}
return returnInfos;
}

I was able to use reflection to get the output I wanted.
Here is the minimal example where the test fails and the output contains all method calls.

service.TestCall2("callA", 2);

liveFastDieYoung.Equals(a);

WCF service without adding reference in WPF

I created a WCF consuming application in WPF by adding service reference.Now its working fine.But now i have a new requirement that is, i want to call the service dynamically by entering the URL,username and password.

You can create a WCF client without adding a service reference with the use of ClientBase, but you will still need a reference to the interface for the compiler to knowwhat functions to call.
It works like this:
public class ServiceClient : System.ServiceModel.ClientBase<IService>, IService {
public ServiceClient() {
}
public ServiceClient(System.ServiceModel.Channels.Binding binding, System.ServiceModel.EndpointAddress remoteAddress) :
base(binding, remoteAddress) {
}
public void Login(string user, string password) {
return base.Channel.Login(user, password);
}
}
NetNamedPipeBinding binding = new NetNamedPipeBinding();
binding.TransactionFlow = true;
EndpointAddress address = new EndpointAddress(youraddress);
ServiceClient client = new ServiceClient(binding, address);
client.Login("xxx", "yyy");

See this website for a general idea. Create a new VisualStudio Solution and add a WCF Service Application project and an Unit Test Project. Put the following code in the test project (a slightly modified version of the code in the link) and add the missing references to the unit test project. Start the WCF service without debugging, change the portnumber in the test if needed and run the test. As mentioned in the article, the code can still use some adjustments before it could be put into production.

I can't change other Class var value with CompileAssemblyFromSource

i try to use CompileAssemblyFromSource to change 1 value at my main class.
But when i compile i get error "Could not load file or assembly or one of its dependencies" and this only happens when i try change static value of other class. But if i return some output or wrote anything at Console from this FooClass than all work's fine. But how can i change value of other class?
using System;
using System.CodeDom.Compiler;
using System.Reflection;
using Microsoft.CSharp;
namespace stringToCode
{
class Program
{
public static int q = 0;
static void Main(string[] args)
{
string source = "namespace stringToCode { public class FooClass { public void Execute() { Program.q = 1; } } }";
Console.WriteLine("q=" + q);
using (var foo = new CSharpCodeProvider())
{
var parameters = new CompilerParameters();
parameters.GenerateInMemory = true;
foreach (Assembly assembly in AppDomain.CurrentDomain.GetAssemblies())
{
try
{
string location = assembly.Location;
if (!String.IsNullOrEmpty(location))
{
parameters.ReferencedAssemblies.Add(location);
}
}
catch (NotSupportedException)
{}
}
var res = foo.CompileAssemblyFromSource(parameters ,source);
var type = res.CompiledAssembly.GetType("FooClass"); //<- here i has error
var obj = Activator.CreateInstance(type);
var output = type.GetMethod("Execute").Invoke(obj, new object[] { });
Console.WriteLine("q=" + q);
Console.ReadLine();
}
}
}
}

You can't find the type because you have compilation error in your code.You can't access the classes in your current code in this manner. You should at least reference the current assembly in your in-memory assembly.
UPDATE
You have two issues in your code. First, you have to make the class Program public. Then you should specify the full name of type in GetType method.
This code works fine:
using System;
using System.CodeDom.Compiler;
using System.Reflection;
using Microsoft.CSharp;
namespace stringToCode
{
public class Program
{
public static int q = 0;
static void Main(string[] args)
{
string source = "namespace stringToCode { public class FooClass { public void Execute() { Program.q = 1; } } }";
Console.WriteLine("q=" + q);
using (var foo = new CSharpCodeProvider())
{
var parameters = new CompilerParameters();
parameters.GenerateInMemory = true;
foreach (Assembly assembly in AppDomain.CurrentDomain.GetAssemblies())
{
try
{
string location = assembly.Location;
if (!String.IsNullOrEmpty(location))
{
parameters.ReferencedAssemblies.Add(location);
}
}
catch (NotSupportedException)
{}
}
var res = foo.CompileAssemblyFromSource(parameters ,source);
var type = res.CompiledAssembly.GetType("stringToCode.FooClass"); //<- here i has error
var obj = Activator.CreateInstance(type);
var output = type.GetMethod("Execute").Invoke(obj, new object[] { });
Console.WriteLine("q=" + q);
Console.ReadLine();
}
}
}
}

Invoke code from string. parameter not accepted

I wish to invoke code that is in selected txt file. It works fine until file content is something simple like "Text string". It also works if i pass string parameter into it. But when i try passing an object like in my case Global it fails. Error is: "The type or namespace name 'Global' could not be found (are you missing a using directive or an assembly reference?)"
Here is some code..
private void button1_Click(object sender, EventArgs e)
{
Scripting scriptObj = new Scripting();
scriptObj.fileName = this.openFileDialog1.FileName;
scriptObj.tekst = File.ReadAllText(this.openFileDialog1.FileName);
string exit = scriptObj.GetAction();
this.label1.Text = exit;
}
namespace WindowsFormsApplication2
{
public class Global
{
public string fileName = "test string";
}
public class Scripting
{
public string tekst = "";
public string fileName = "";
public string MyMethod1(Global obj) { return (obj.fileName); }
public string GetAction()
{
string sourceCode = #" namespace WindowsFormsApplication2 { public class Scripting { public string MyMethod (Global obj) { return (" + tekst + "); }}}";
var compParms = new CompilerParameters
{
GenerateExecutable = false,
GenerateInMemory = true
};
var csProvider = new CSharpCodeProvider();
CompilerResults compilerResults = csProvider.CompileAssemblyFromSource(compParms, sourceCode);
if (compilerResults.Errors.HasErrors)
{
StringBuilder errors = new StringBuilder("Compiler Errors :\r\n");
foreach (CompilerError error in compilerResults.Errors)
{
errors.AppendFormat("Line {0},{1}\t: {2}\n",
error.Line, error.Column, error.ErrorText);
}
return errors.ToString();
}
else
{
Global newGlobal = new Global();
newGlobal.fileName = "TEsTfileNameToOutput";
object typeInstance = compilerResults.CompiledAssembly.CreateInstance("WindowsFormsApplication2.Scripting");
MethodInfo mi = typeInstance.GetType().GetMethod("MyMethod");
string methodOutput = (string)mi.Invoke(typeInstance, new object[]{ newGlobal });
return methodOutput;
}
}
}
}
Why does
public string MyMethod (Global obj) { return (" + tekst + "); }
not take Global as param, but it works ok with MyMethod1
public string MyMethod1(Global obj) { return (obj.fileName); }
Content of selected file is: obj.fileName

You haven't included a reference to the current assembly, which is the assembly declaring Global. Therefore the compiler has no idea which type you're talking about.
You need to set the ReferencedAssemblies property in the CompilerParameters that you're creating.

Passing custom object across AppDomains

I compile a plugin and then create an instance of it in a new AppDomain. Then I want to execute a method in the plugin object but that results in an ArgumentException:
"Object of type System.MarshalByRefObject can not be converted to type Data"
The code below should be compilable and result in the exception above. To make it work you must also sign the Assembly (Project -> Properties -> Signing -> Sign the assembly -> New ...)
IPlugin.cs:
using System;
namespace Plugin
{
[Serializable]
class Data : MarshalByRefObject
{
int value;
}
interface IPlugin
{
void DoStuff(Data data);
}
}

var domain = AppDomain.CreateDomain(DomainName, null, setup, permissions, fullTrustAssembly);
return (Sandbox)Activator.CreateInstanceFrom(domain, typeof(Sandbox).Assembly.ManifestModule.FullyQualifiedName, typeof(Sandbox).FullName).Unwrap();
}
public bool CreateInstance(string assemblyPath, string scriptType)
{

var assembly = Assembly.LoadFrom(assemblyPath);
CodeAccessPermission.RevertAssert();

if (type == null)
return false;
instance = Activator.CreateInstance(type);
return instance != null;
}

{

return info.Invoke(instance, parameters);
}
}
private static void CompileToFile(string code, string ifaceFile, string output)

}
}
}

It must be a type known at both sides of your communication!
