Unable to mock the ref and out parameter of the function

Unable to mock the ref and out parameter of the function, test case fails occasionally.

Sample code:

Test case:

public void test1()
{
string expected = null;
string s1 ="hi";
string s2="hello";
string xpected = "pound";

string key = "Test";
langType ret_lang = langType.English;
using (RecordExpectations recorder = RecorderManager.StartRecording())
{
string Lang = privateTarget.CLanguage(ref key, ref ret_lang);
recorder.Return("pound").RepeatAlways();
}

privateTarget.CLa(key, ref s1, ref s2);

Assert.AreEqual(expected, s1, "s1_CLa_expected was not set correctly.");
Assert.AreEqual(xpected, s2, "s2_CLa_expected was not set correctly.");

}

Public void CLa(key, ref s1, ref s2)
{
s1 = null
s2= null
...
..........
string key = "Mother Tongue"
langType ret_lang = langType.French;

string st = CLanguage(key, ref ret_lang);

....
...

If ret_lang = French Then

s1 = st
Else
s2 = st

Endif
.....

}

When the test case fails the ret_Lang = French. Thus mocking the ref and out parameter fails occassionally.

I have tried the dynamic mocking but still the test case fails ocassionally.


I am not able to make the test case pass consistently.

Typemock.NET version 4.1.0.0

The Testcase is in C#.Net and the
Function is in VB.Net

Please help me out to resolve this issue.

Thanks in advance.
