Visual Studio Professional 2019 - version 16.6.3

JustMock 2019.1.115.2 (Commercial version)

My solution has 3000+ unit tests and suddenly, 1000+ tests failed with the error :

 Message: 
    Test method Cloee2.Ws.UnitTests.Services.Business.TestConditionsAdmissionSe2.GetClasseGeneriqueNulle threw exception:

They pass in debug, but not in run.

I try to clear bin and obj folder of my solution, but nothing to do.

Any idea ?

Hi,

I'm using JustMock to mock SharePoint objects in some Unit Tests. When I run Unit Tests (I use ReSharper as test runner) and the JustMock profiler is enabled, the unit tests are much slower. Normally, one Unit test runs within seconds. With the JustMock profiler enabled, I have to wait several minutes. Is there something I can do to accelerate this?

 

Thank you very much!

 

I have the following in a test (my first ever JustMock test, I might add)...



The class being Mocked looks like this ...


When I attempt to run the test I get ...

Can anyone point out what I've done wrong?

I put out a question on stackoverflow, but did not get any response. So let me link it here: https://stackoverflow.com/questions/61074264/how-can-i-mock-multiple-instances-of-a-struct

For convenience a copy of the text:

 

I have a `struct` that I want to mock. In a more complex test I need several instances of this struct, each with it's own behavior. To facilitate this, I've created a helper method.

    private MyStruct CreateMock(string toString) {
        var mock = Mock.Create<MyStruct>();
        Mock.Arrange(() => mock.toString()).Returns(toString);
        return mock;
    }

When I debug a test where this method is called multiple times, it appears as if the `Arrange` call is overwritten for ALL instances of the struct (or maybe I am using struct mocking instead of instance mocking?). 

I've tried:

    mock.Arrange(m => m.toString()).Returns(toString); // Using Helpers assembly, note the lowercase m at the start of the line.

But to no avail. How can I get multiple instances of a struct?

I am trying Arrange a  base class method which is override in drive class but I can`t

Here is my Code :

 public class Class1 : Class2
    {
        public bool Class1Call { get; set; }

        public override void Method1()
        {
            Class1Call = true;
           base.Method1();      //<<<<< want to ensure that base.Method1 ic call during Method1 call
        }
    }

    public class Class2
    {
        public bool IsCall { get; set; }

        public virtual void Method1()
        {
            IsCall = true;
        }
    }


    public class TestClass
    {
        [Fact]
        public void Class_1_Test()
        {
            var foo = Mock.Create<Class1>();
            Mock.Arrange(() => (foo as Class2).Method1()).CallOriginal().OccursOnce();
            Mock.Arrange(() => foo.Method1()).CallOriginal().OccursOnce();

            foo.Method1();

            Mock.Assert(foo);

            Assert.True(foo.IsCall);

        }
    } 

hi mate, I was wondering if it is possible to mock the following case.

 

from school in dbContext.Schools

join student in dbContext.Students

   on school.id equals student.schoolId into students

let firstStudent = students.FirstOrDefault()

select firstStudent.Name;

 

When all the tables are empty and there is no school and no student in the tables, a real sql execution just returns an empty object of IEnuemrable<string> type. If I mock 'dbContext.Schools' and 'dbContext.Students', 'firstStudent.Name' throws a null exception because 'firstStudent' is null.

Is there a way to conditionally mock only in this context of linq to sql so that we can bypass the null exception and get the mocked execution to run smoothly?

Hi ,

I am actually intended to write a UT  for the following code.
Private void GetVersion(){
string version=GetLatest();
if(string.IsNullOrEmpty(version))
Throw new InvalidException("Ivalid version");

How to write a unit test for the above code?

Hello,

We're encountering the following type of error on our build servers:

  X SendFile_GivenValidInformation_ShouldReturnSuccessResult [1ms]
  Error Message:
   Initialization method InsuranceApiLibrary.Syncronizers.<<redacted>>Tests.Setup threw exception. Telerik.JustMock.Core.ElevatedMockingException: Cannot mock '<<redacted>>SoapClient'. The profiler must be enabled to mock, arrange or execute the specified target.

Disable the profilers or link them from the JustMock configuration utility. Restart the test runner and, if necessary, Visual Studio after linking..

When we exclude code coverage, we get very similar errors, but without the lines about detected third-party active profilers.  I have directly verified that the JM profiler settings are correct (see attached images).

Our build servers have Visual Studio Enterprise 2019 16.4.2, .NET Core SDK 3.1.100, and JustMock 2020.1.113.1 installed.  The C# projects in question target .NET Core 3.1.  The path to the JM DLL being referenced by those projects is "C:\Program Files (x86)\Progress\Telerik JustMock\Libraries\netcoreapp2.0\Telerik.JustMock.dll".  I can find no obvious alternative path or DLL for .NET Core 3.x, so I assume that DLL applies to multiple .NET Core major versions.

This problem is blocking new initiatives.  Thanks in advance for any assistance you can provide.

Hi ,

I want to write a unit test for a small class where it has following execution paths

 private bool? DetermineCheckState()
        {
            try
            {
               

                //1.where  ProjectsOperationData is a ObservableCollection<ProjectOperationData>{get;set;}

               //2 IsSelected is a public property in ProjectOperationData Class
                bool allChildrenChecked = ProjectsOperationData.Count(x => x.IsSelected == true) == ProjectsOperationData.Count;
                if (allChildrenChecked)
                {
                    return true;
                }

                //2. returns false if any project is not selected in Project Operations Form
                bool allChildrenUnChecked = ProjectsOperationData.Count(x => x.IsSelected == false) == ProjectsOperationData.Count;
                if (allChildrenUnChecked)
                {
                    return false;
                }
            }
            }

            return null;
        }

 

Can anyone suggest a way to write unit test?
