> A suggestion to enable Java assertions in the project's build xml when
> running tests. I think this would improve the build quality.
> To enable assertions add the following snippets to the JUnit tasks in
> build.xml:
> <assertions>
> <enable />
> </assertions>
> --
> For example:
> <junit ... >
> ...
> <assertions>
> <enable />
> </assertions>
> </junit>
