<div class="markdown_content"><p>I plan to add Unit tests for our future application with the Test Manager.<br/> A framework allows me to test the most function blocks really easy.<br/> Unfortunately, i also have methods which use functions of System-dependent libraries.</p> <p>Best example is, that i need to synchronize my system time with a external clock:<br/> [-img src=Screenshot 2022-02-28 231445.png: missing =-]</p> <p>For the synchronization i currently use the SysTimeRtcSet function of the eponymous library. Each run of a test case for the synchronization method will call this function and manipulate my system time.</p> <p>I started to replaced this function by using the DateTimeProvider of the Util library, which at least implements an iDateTimeProvider interface. But the DateTimeProvider only allows me to GetDateTime().</p> <p>How can i dissolve my dependency? How does CODESYS want me to dissolve this?</p> <p>Thanks for any help!!</p> <p>PS: The function is only in use, but not under test.<br/> PPS: I don't want to use pragmas for testing code run.</p></div>
