I have the same issue as above. The problem I am having is that I am not mocking the private method but I am using the MSTest private accessor object in order to call the private method I am testing. The mocked objects are public here is some code to illustrate the issue.
///<summary>
/// A test for ProcessIncomingMessage
///</summary>
[DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML", "|DataDirectory|\\incoming.xml", "Event", DataAccessMethod.Sequential), DeploymentItem("TestResources\\Unified\\incoming.xml"), TestMethod]
public void ProcessIncomingMessageTest()
{
var expectedTower = TestContext.DataRow["Tower"].ToString();
var expectedEventDescription = TestContext.DataRow["EventDescription"].ToString().TrimStart('\r', '\n', ' ');
expectedEventDescription = expectedEventDescription.TrimEnd(' ', '\n', '\r', '\0');
var rawDataToUse = Convert.FromBase64String(TestContext.DataRow["RawData"].ToString());
var target = new UnifiedProtocolTranslator_Accessor(); // TODO: Initialize to an appropriate value
bool called;
Mock.Arrange(() => target.StoreMessages(Arg.IsAny<byte[]>(), Arg.AnyInt)).IgnoreArguments().DoInstead((byte[] arg1,int arg2) => called = true).MustBeCalled();
Mock.Arrange(()=> target.ClearBuffers()).DoNothing().MustBeCalled();
bool expected = true; // TODO: Initialize to an appropriate value
bool actual;
actual = target.ProcessIncomingMessage(rawDataToUse, rawDataToUse.Length);
Assert.AreEqual(expected, actual);
Mock.Assert(target);
}
When I call the ProcessIncomingMessage method I expect that StoreMessages and ClearBuffers are mocked, yet it goes and executes those methods as if they were not mocked.
Thank you in advance.
