Using TMap Contains( ) with automated unit testing can result in a false return, when the element of the TMap exists.

If a user relies on the automation unit testing, they can get a incorrect result when using TMap because Contains( ) doesn't always return the correct result.

1. Download attached project and extract
2. Right-click FailTest.uproject and generate Visual Studio project files.
3. Open project Visual Studio file.
4. Run project as Development Editor
5. In editor, select Window->Developer Tools->Sessions Frontend
6. Select "Editor" from the left side panel.
7. Select Automation from the tabs in Sessions Frontend window.
8. Check the box for FailTest from the Automation lists
9. Click, "Start Tests"

Result:

Second Contains( ) returns false even though TMap has element it is looking for.

Expected:

TMap Contains( ) function finds existing element in TMap
