The cause of failure is not known as of now. It may be that the tests themselves need to be fixed.

**For re-enabling the tests -**
1. Search for the methods named as above in the code. ( like search for `state_single12_1_1` in `StateSuite.cs` )
2. Comment out the `DisabledTestCase` attribute before the test function.

To run the tests in isolation, use the following command
```
.\RunTests.cmd /Area=Annotations /Name=
```
`` is the full name mentioned above in the list ( e.g. `StateSuite.state_single12_1_1.fixed` )

For debugging the tests, add the `/DebugTests` argument in the command above.
