The documentation on Fluent Mocking ends with this statement:
Important
Note that when you use Fluent Asserts only arrangements marked with either MustBeCalled or Occurs will be verified. For other tests you have to use the explicit assert.
What this fails to note is that, while this is true of the function "Assert", there is another function, "AssertAll", which will flag an error if any Arranged function call was not utilized.
On a related note, I left other suggestions for this same page a day or two ago. I would have liked to leave the above statement using the same feedback utility, but I can no longer find the control that I used to leave those initial suggestions.
We are trying to run unit tests via xUnit and mocking method occurence using JustMockLite. Method under arrange is creating a underlying Task however, once in a while test fails with following error

Update reference functionality wrongly suggests updating JustMock assembly reference and even more - detects currently referenced one as a lite version, see the screenshot below:
When a breakpoint is added inside an async test that uses JustMock the debugger is failing to hit it.
To reproduce the issue follow the next steps:
1. Open the attached project
2. Create a breakpoint at the first arrangement in the async test method.
3. Start debugging the async test
Result: the breakpoint is not hit.
The issue is observed for both .NET Core and .NET Framework.
The test run is aborted when a .testsettings is used for executing JustMock tests. The .testsettings contains only a description.
<?xml version="1.0" encoding="UTF-8"?>
<TestSettings name="Local" id="15694c75-be1c-4113-9d42-2cbe1013c41c" xmlns="http://microsoft.com/schemas/VisualStudio/TeamTest/2010">
<Description>These are default test settings for a local test run.</Description>
</TestSettings>
It seems that the usage of the MSTest element is breaking the execution.
Workaround: As .testsettings are deprecated use .runsettings instead without MSTest element.
My team and I have spotted some odd behaviour with the latest version of JustMock (2015.3.929.5) when targeting a Windows Store app.
If we create a mock for an object in a helper method, the mock fails when making assertions for calls to the mock.
The following code illustrates the issue:
[TestMethod]
public void ThisWillFail()
{
var subject = CreateSubject();
subject.DoSomething();
subject.Assert(s => s.DoSomething(), Occurs.Once());
}
[TestMethod]
public void ThisWillPass()
{
var subject = Mock.Create<ISubject>();
subject.DoSomething();
subject.Assert(s => s.DoSomething(), Occurs.Once());
}
public interface ISubject
{
void DoSomething();
}
private static ISubject CreateSubject()
{
return Mock.Create<ISubject>();
}
In this code, the first test will fail but the second test will pass. The only difference is that, in the first test, we're setting up the mock in a helper method.
We have a "Unit Test Library (.NET for Windows Store apps)" referencing the Telerik.JustMock assembly. I have attached a simple project containing this implementation.
It's worth noting that the same code passes in a regular .NET class library; it only fails in a "Unit Test Library (.NET for Windows Store apps)". It's also worth noting that this worked under an older version of the assembly (2014.3.1021.2).
Any help would be appreciated, as we currently have around 3,000 tests and a good proportion of them set up their mocks using a helper method in this way.
