Dear Telerik team,
It is nice to have a way to generate mocks.
But it is annoying to have lots of those messages for references in XML comments. I had to turn the feature off. Which might be the case for other customers too.
Maybe you want to have a look into it.
JustMock interprets anonymous types as tuples. The sample below demonstrates the issue:
public interface IAnsweringService
{
(int code, string desc) GetAnswer(string question);
}
[TestMethod]
public void AnswerToTheUniverseQuestionTest()
{
var apiMock = Mock.Create<IAnsweringService>();
var expectedAnswer = new { code = 42, desc = "Answer to the Ultimate Question of Life" };
Mock.Arrange(() => apiMock.GetAnswer(Arg.AnyString)).Returns(expectedAnswer);
var actualAnswer = apiMock.GetAnswer("What is a universe question answer?");
Assert.AreEqual(expectedAnswer.code, actualAnswer.code);
Assert.AreEqual(expectedAnswer.desc, actualAnswer.desc);
}
Telerik.JustMock.Core.MockException: The chained return value type '<>f__AnonymousType1`2[System.Int32,System.String]' is not compatible with the arranged method's return type 'System.ValueTuple`2[System.Int32,System.String]'
The following code snippet causes a hang in the test execution while being debugged:
Mock.SetupStatic(typeof(TimeSpan), Behavior.CallOriginal, StaticConstructor.NonMocked);
Mock.Arrange(() => TimeSpan.FromSeconds(15)).Returns(TimeSpan.MinValue);
The issue can be temporary solved by disabling the DebugWindow via JustMock extension menu.
Hello
I generate a syntax tree which I will format with Formatter.Format() from the package Microsoft.CodeAnalysis.CSharp.Workspaces 4.4.0 and .NET 6. A test exists where the formatter is used but when the JustMock profiler is enabled an InvalidProgramException is thrown. When the profiler is disabled everything works fine. It fails on Windows and on Linux.
Message:
System.InvalidProgramException : Common Language Runtime detected an invalid program.
Stack Trace:
ContextIntervalTree`2.ctor(TIntrospector& introspector)
FormattingContext.ctor(AbstractFormatEngine engine, TokenStream tokenStream)

You can reproduce this by writing an unit test for that (I used xUnit):
[Fact]
public void Test1()
{
var classText = @"using System; namespace TestNameSpace.Orders { public class Order
{
public Guid Id { get; set; }
}
}";
var syntaxTree = CSharpSyntaxTree.ParseText(classText);
var workspace = new AdhocWorkspace();
var formattedClassText = Formatter.Format(syntaxTree.GetRoot(), workspace).ToFullString();
var expected = @"using System;
namespace TestNameSpace.Orders
{
public class Order
{
public Guid Id { get; set; }
}
}";
Assert.Equal(expected, formattedClassText);
}
}
See attachments. We do not use the free edition.

Considering the following simple test scenario:
public abstract class TestBase
{
public static TestContext TestContext { get; set; }
}
[TestClass]
public class UnitTest1 : TestBase
{
[ClassInitialize]
public static void ClassInitlialize(TestContext ctx)
{
TestContext = ctx;
}
[TestMethod]
public void TestMethod1()
{
}
}
[TestClass]
public class UnitTest2 : TestBase
{
[ClassInitialize]
public static void ClassInitlialize(TestContext ctx)
{
TestContext = ctx;
}
[TestMethod]
public void TestMethod1()
{
}
}
Attempt to run the tests above with JustMock profiler enabled fails with System.InvalidProgramException. The issue is not reproducible with MSTest.TestFramework and MSTest.TestAdapter packages prior to 3.0.x.
The issue is demonstrated with the following sample:
[Theory]
[MemberData(nameof(GetMemberDataContext))]
public void ValidParameters_Success(int param1, int param2)
{
// Arrange
Mock.SetupStatic(typeof(MyClass), Behavior.Strict, StaticConstructor.Mocked);
Mock.Arrange(() => MyClass.method1()).Returns(true);
// Act
IService service = new Service();
bool result = service.method2();
// Assert
Assert.True(result);
Mock.Assert(() => MyClass.method1(), Occurs.Once()); // <-- the test fails here because it reports that method invocation occurs twice
}
The issue in not observed if the code is modified in the following way, which indicates behavioral incinsistency:
[Theory]
[MemberData(nameof(GetMemberDataContext))]
public void ValidParameters_Success(int param1, int param2)
{
// Arrange
Mock.SetupStatic(typeof(MyClass), Behavior.Strict, StaticConstructor.Mocked);
Mock.Arrange(() => MyClass.method1()).Returns(true).OccursOnce();
// Act
IService service = new Service();
bool result = service.method2();
// Assert
Assert.True(result);
Mock.Assert<MyClass>();
}
if you use the C# using declaration and have JustMock advanced (elevated) mode enabled, the runtime will throw an InvalidProgramException.
Find below the sample code that demonstrates the issue:
public class TestClass : IDisposable
{
public void Dispose()
{
}
}
[TestClass]
public class Fixture
{
public interface ITest { }
[TestMethod]
public async Task Test()
{
ITest mock = Mock.Create<ITest>();
using TestClass test = new();
}
}
The threading model of UI apps differs from the test host and this might become a source of issues like the following: System.InvalidOperationException: "The calling thread must be STA, because many UI components require this". The request is about extending JustMock with some helpers that can be used to solve this issue easily.
Considering the sample class
using Azure.Messaging.ServiceBus;
public class Class2
{
private static ServiceBusSender messageToTopicSender;
private static string topicName;
public static void SetRequestTopicClient(string serviceBusConnectionString, string topName)
{
topicName = topName;
ServiceBusClient serviceBusClient = new ServiceBusClient(serviceBusConnectionString);
messageToTopicSender = serviceBusClient.CreateSender(topicName);
}
}
and the following tests
[TestClass]
public class Class1Test
{
[TestInitialize]
public void SetUp()
{
Mock.Arrange(() => Class2.SetRequestTopicClient("", "")).DoNothing();
}
[TestMethod]
public void TestA()
{
Class2.SetRequestTopicClient("", "");
}
}
[TestClass]
public class Class2Test
{
static ServiceBusClient serviceBusClient = Mock.Create<ServiceBusClient>();
ServiceBusSender messageToTopicSender = Mock.Create<ServiceBusSender>();
[TestInitialize]
public void SetUp()
{
Mock.Arrange(() => new ServiceBusClient("conStr")).Returns(serviceBusClient);
Mock.Arrange(() => serviceBusClient.CreateSender("myTopic")).Returns(messageToTopicSender);
}
[TestMethod]
public void TestB()
{
Class2.SetRequestTopicClient("conStr", "myTopic");
}
}
Executing the tests in order TestA -> TestB results in failed TestB, but changing the order or runining them standalone succeeds.The outcome of the tests should not be dependent of the execution order.
The new public API should allow the developer to access the invocations for a particular arrangement. Something like the following:
IEnumerable<IInvocaiton> invocations = foo.GetInvocationsFor((x) => x.CalcData(2, 2));
