Verifying Constructor Calls

0 votes
Hello,

Maybe this feature already exists, but I had the thought that it may be useful to be able to verify that a constructor call was made. For instance, if you were trying to validate this property in an object:

public ValuesCollection Values
{
get
{
if (_values == null)
_values = new ValuesCollection();
return _values;
}
}

I could then, in my test code, verify that the constructor of the ValuesCollection was called:

Isolate.Verify.ConstructorWasCalled<ValuesCollection>();

Hi Brian,

Isolator AAA API does not have this feature yet - I'll suggest thios feature for future version of Isolator.
Until we'll implement it you could use the old natural/reflective API instead

Does that feature have been added since?

Or do you have an example of a solution using old natural/reflective API?

Thanks

Hi,
You can use the old API in order to do that, the concept of verify is a bit different here since you are verifying on all the recorded expectations.

For example the test below will fail since you recorded an expectation on the constructor of DummyClass but did not call it. If you'll uncomment the call to the constructor the test will pass. 

[TestMethod]
public void Test()
{
    using (RecordExpectations r = RecorderManager.StartRecording())
    {
        new DummyClass();
    }
    
    //DummyClass dummy = new DummyClass();
    MockManager.Verify();
}
