Update as of 2025: This function (IECStringUtils.FormatDateTime) doesn't make any sense there isn't any parameter that accepts a Date_Time value. I have no idea what's purpose even is. I am going to use StuSprintf from the StringUtils library for this purpose.
Note: I should say they are marked INTERNAL, not PRIVATE
Note: I should say they are marked INTERNAL, not PROTECTED
Test Suit Methods should be Protected not Private
AssertEquals_String doesn't work for Strings longer than 255 characters
this can be closed BTW
I think this is the same or similar to https://forge.codesys.com/lib/counit/tickets/58/ I figured out that this was occurring because assert was being called continuously
Seems to work now. Can this be closed?
