I have a class which has a large number of properties each of which returns a double, and a method under test which takes a string, and an instance of the class, and calls one of these properties based on the value of the string (effectively, it calls the property whose name is the string). I am using NUnit, which provides for parameterised testing. I would like to test the method with a set strings, but this means arranging for the specific property call. I am quite close, but I can't quite get it to work.

So far I have the following. A set of test parameters, defined as a Dictionary:

public static Dictionary<string, System.Linq.Expressions.Expression<Func<IMyClass, double>>> SpecialProperties = new Dictionary<string, System.Linq.Expressions.Expression<Func<IMyClass, double>>>()
{
    {"InlineLength", x=>x.InLineLength},
    {"BranchLength", x=>x.BranchLength},
    {"TotalLength", x=>x.TotalLength},
    {"CentreLineLength", x=>x.CentreLineLength},
    {"SurfaceArea", x=>x.SurfaceArea},

}

 

Then I have the test method:

[Test]
[TestCaseSource("SpecialProperties")]
public void SpecialProperties_Test(string specialPropertyName, System.Linq.Expressions.Expression<Func<IMyClass, double>> specialProperty)
{
    IMyClass mockMyClass = Mock.Create<IMyClass>(Behavior.Strict);

    mockMyClass.Arrange(specialProperty).Returns(9.99);

   double result =  _concreteInstanceOnTest.MethodOnTest(specialPropertyName, mockMyClass);

    Assert.AreEqual(9.99, result);

}

This very nearly works, but I get an Inconsistent Accessibility error - Expression<Func<IMyclass, double>> is less accessible than SpecialProperties_Test(). I'm obviously not doing it quite right. Can anybody help?

I'm not sure if this is a JustMock question, but it may be. I'm trying to test a Kendo datasource 'read' method which is implemented in my MVC controller. The datasource is actually part of a grid definition, but I have others that are in auto-complete controls.

The following is a fragment of my grid definition in the view.

 

My controller methods is:

 

and a fragment of my test is:

 

When I run my test, the controller throws and exception:

 

 

System.ArgumentNullException: 'Value cannot be null.'  Message:"Value cannot be null.\r\nParameter name: source"

Obviously I'm not setting up the 'request' properly, althought I don't exactly know what's wrong.

Rather than spin my wheels trying to figure that out, I wonder if you can advise me on the recomended approach to testing datasources.

TIA

Hi there, I'm trying to profile a very slow unit test using Visual Studio 2015 Enterprise, but this unit test uses JustMock.

 When I try to profile the test, it returns with the following exception:

"Telerik.JustMock.Core.ElevatedMockingException: Cannot mock 'ActuIT.Futurama.Config.Settings'. The profiler must be enabled to mock, arrange or execute the specified target.
Detected active third-party profilers:
* {C60A40F7-B6A2-428C-8E87-E1BF6563F650} (from process environment)
Disable the profilers or link them from the JustMock configuration utility. Restart the test runner and, if necessary, Visual Studio after linking."

 I've already linked the "Visual Studio 2015 Code Coverage/IntelliTrace" profiler in the Justmock settings, but this didn't change a thing.

 Does anyone have a solution?

 

Hi

 

Does JustMock support unit testing for ASP .Net Core projects?

I am facing some dependency issues when i use JustMock to test ASP .Net Core project.

 

Thanks and Regards

Expected Behavior: RecursiveLoose mocking behavior will cause every method to return a mocked object for reference types.
Actual Behavior: When RecursiveLoose runs into an interface that derives from IEnumerable<T>, the returned mocked object does not get recursively mocked causing NullReferenceException when a test attempts to access members on the mocked object (IBaz in the example above).

The above is a simplified test case to narrow down the source of the bug.  If I have an IEnumerable<T> property on IFoo instead, then the returned object is correctly mocked (GetEnumerator doesn't return null).

As shown in the above example on line 29, mocking an IBar directly works.  It is only when attempting to recursively mock an object that derives from IEnumerable that the problem occurs.

Does JustMock has smart unit test suggestions feature like TypeMock Suggest? Please let me know

I am trying to test async method but i am getting null reference exception.

I have a service that has a GetAll method which is async: public async Task<IQueryable<T>> GetAll()

and the method under test is calling this method: await _service.GetAll();

I am mocking the service and then doing an arrange on the getAll method, but i get a null reference exception when the method is called in the code under test.

Mock.Arrange(() => mockService.GetAll()).Returns(Task.FromResult<IQueryable<Models.VM>>(vms.AsQueryable()));

 

Thanks

Sorry if this is a noob question on JustMock, but I'm still learning the package.  

 

VS 2017 Enterprise 15.2(26430.6) Release
.NET Framework 4.6.01586
XUnit.net 2.2.0

Created a unit test for testing an email module where I'm mocking the SmtpClient to keep it from actually sending emails in unit tests.  When I run the tests either all together or individually, they run properly.  When I attempt to use the Test->Analyze Code Coverage, several of them fail with:

I've tried some of the suggestions I've found in other forum topics like disabling Intellitrace, running VS elevated and enabling the VS2015 Intellitrace option in the JustMock Options menu.  None of these combinations appear to make any difference.  As it is, I'm unable to view code coverage using these unit tests which limits the usability.

 

Here's the code that passes except under Analyze Code Coverage:

 

Anyone have any suggestions?  Is this a bug, a known issue with VS2017 and JustMock or just me being too new to JustMock a.k.a.I screwed something up?

 

 

Hi,

 

I have 2 interfaces (I1 and I2) that have a property called FileName. Another interface is inheriting these two interfaces. Let us call it I3.In I3, I am using new modifier (this is C#) so that in my code I do not get FileName property displayed twice and prevent compiler ambiguity errors.

When I mock interface I3 and set the FileName value, this value does not propagate to interfaces I1 and I2. This is not an issue in my actual code. 

I have attached a sample pictures of the code. The first assert works. Second and third fail.

Assert.IsTrue(toTest.FileName == @"test file name", "FileName missing"); //1
Assert.IsTrue((toTest as Interface1).FileName== @"test file name","FileName missing"); //2
Assert.IsTrue((toTest as Interface2).FileName == @"test file name", "FileName missing"); //3

Am I doing something wrong OR is this a bug with the lite version of JustMock?

Thank you for time taken to read and any direction to resolve my challenge.

Hi there

Is there any early access program or something similar for JustMock? Due to some license problems I had to move to Visual Studio 2017 RC and now I desperately need the JustMock Profiler...

Any chance?

Thank you for your help
