 * Checks if the resource at the given location can be executed as a test. The location may point to an N4JS project

 * or not; for example, to enable or disable a "Run as test" context menu item). This method does not check all
 * details because many checks are better handled at later stages when meaningful error messages can be provided to
 * the user.
